Robust operating systsems for the Mac

One week with Lion

OS X

A hype update, so far.

The real story of Lion.

While committed Mac OS X users have little choice but to update to Lion sooner or later and, at $30 it’s hardly a big deal economically, how much better is Lion than its rock stable predecessor, Snow Leopard?

I think there are two answers to this. For the casual user who grew up with iOS on the iPhone or iPad and who has a Mac laptop or is willing to spend another $80 on a trackpad for his desktop Mac, Lion probably works well. Many of the familiar iPad gestures are there, software is available by download only from the Mac store and eye candy in the guise of Mission Control and the like is there in abundance. Further, if you like the rendering of ‘Conversations’ in Apple iOS Mail, where it’s easy to scroll through a thread of exchanges, then you will also like this added feature in Lion.

But for longer time users Lion is nothing more or less than a pain in the you-know-what. You lose all your prized PPC applications, Apple having deleted the Rosetta emulator to force those with PPC iMacs to upgrade their hardware and software, making Lion the most expensive OS upgrade ever for these users. If your broadband is slow or bandwidth limited, forget about downloading the OS and many of the larger apps from the App Store. Life is too short and the telcos and cable companies too greedy. And if you use peripherals which require dedicated drivers, then you are going to be hunting around for these – or waiting for them to be released – before your hardware can be ‘un-bricked’. This happened to my external USB wireless dongle and my third display driven by a USB-to-DVI adapter. Mercifully, both vendors were really on the ball, and new drivers have been installed and functionality recovered. Also, thankfully, my Brother HL-2170W and HP DesignJet 90 printers continue to work every bit as well as they did with Snow Leopard.

Those suffering from confirmation bias – you paid for it so it must be good – will regale you with tales of how much faster Lion is than Snow leopard. Utter nonsense. Objective test measurements show it is 2-5% slower and your machine will run 5-7F hotter. Good luck if you are using one of Apple’s cooling-challenged iMacs where sleek design has made CPU and GPU cooling an afterthought. And if you choose to install your own SSD, search out TRIM Enhancer for garbage management because Apple has made sure that Lion’s built-in TRIM capabilities will be denied you, reserved for Apple-installed overpriced SSDs only. An indicator, if ever one was needed, of the growing ‘make a buck at any cost and squeeze your customer until the pips squeak’ mentality becoming increasingly pervasive at 1 Infinite Loop.

And those same long time OS X users will find they have to spend time reversing all the garish, dumbing down of Lion to make it look and feel like what was so well done by Snow Leopard. I address many of the more common issues here.

So what’s good? After one week of intense use with many applications I have had no lock-ups or glitches on any of my HackPro (Core2Quad 2.83gHz, 8gB RAM, Nvidia 9800GTX+ graphics, 2 SSDs, 2 HDDs), MacBook Air (11″ mid-2010 Core2Duo 1.4gHz, 2gB RAM model with integrated Intel 320M graphics. SSD) or Mac Mini (2010 model, Core2Duo, 5gB RAM Intel 320M, HDD). On my main work machine, the HackPro, hacking Lion for installation was the easiest yet, Hackintosh support having improved mightily in the past few years. Further, running a half-dozen big apps simultaneously is no big deal. This includes Photoshop CS5, Lightroom 3, iPhoto, Safari, Firefox, iBank, Word 2008, Excel 2008, Numbers, Pages, you name it. Just like Snow Leopard.

For that we should be truly grateful. Most of the other ‘enhancements’ are simply a waste of time – the time it will take a demanding user to reverse them. But if you do not want to be locked out of the Apple ecosystem and its upcoming iCloud, updating to Lion becomes a requirement.

An efficient Lion installation

OS X

Saving space.

If you use a Solid State Drive for your Mac OS and apps, then you know that the small, costly SSD can fill up quickly. If you download Lion from the App Store onto a machine with Snow Leopard installed, the download is what Apple calls an ‘incremental’ one. Only changed files are updated. OS X aficionados swear than the only real OS X installation is a ‘clean’ one, meaning you install Lion on a fresh drive or partition and then migrate over from your Snow Leopard drive or partition just what you need. I have never seen any comparative performance measurements to substantiate this claim so, until I do, I disregard it as so much urban myth.

So assuming you do an incremental install, one thing the installer will not do is erase apps and files you no longer need.

Which are these?

First, any PPC app – one written to run on Apples using IBM G3/4/5 CPUs, will no longer run. The brilliant PPC emulator software known as Rosetta, included through the last version of Snow Leopard, is no more. Which of your apps are PPC? Go to Applications->Utilities->Activity Monitor and click on the ‘Kind’ column heading to sort your apps by Intel, Intel (64 bit) and PPC.

Activity Monitor displays which CPU apps run on.

Well, guess what. As long as you have copies of your PPC apps in a Snow Leopard disk or partition, you might as well delete these from your Lion installation because there’s no way they will ever work.

Well, how about all the other crud which has built up from generations of machines? Time to fire up the free Omni DiskSweeper which, after a few minutes grinding (or few seconds if you use an SSD) will tell you where all your files reside, sorted by size in decreasing order. Now you can get serious about purging stuff, but do make a backup before you go ballistic.

Here’s my Users directory – the biggest part of which is MobileSync (backups of iPad/iPhone etc which could be erased); Music can be moved to an HDD. VirtualBox is only needed if you must run Windows. That lot comprise some 18gB of the 30.3gB,meaning you only really need 12gB for Users:

Add to that Applications, which means Applications+Library+usr:

All the Lion stuff adds another 5gB.

Here are my biggest Apps:

From the above approach you can figure what you need on an SSD boot drive which is to contain OS Lion + Users + Apps/Library and hence how large the SSD needs to be, allowing +10% for free space used for temp/scratch files, Mac OS X updates and any new apps you decide to add.

I suspect that, unless you have tons of big apps and/or a huge mail database, 40gB will do it nicely for you – meaning use 36gB and keep 10% free. My SSDs are 120gB but if I was normal you wouldn’t be reading this.

Update:

Reader Fazal Majid has pointed out below in his Comment to this post that there’s a free app named Monolingual which does all of the above and more. I used it and gained 0.51gB on my SSD (Monolingual erroneously reported a gain of 1.0gB) compared to the status immediately after upgrading to OS Lion. It took a couple of minutes to run and I could see it extracting PPC code from many current apps like iPhoto and Lightroom. The apps remaining on my HackPro continue to run fine.

You can download Monolingual by clicking below:

Click to download Monolingual.

However, a check of the Library->Application Support directory disclosed that related files in this directory were not removed. They are, for the most part, small, but it’s a shame the app authors did not go all the way. Still, the price is right.

Thanks Fazal!

Windows with Lion

OS X

For the masochists among you.

My prime, nay, sole, motivation for installing Windows on my Lion Hackintosh was to allow me to look at some computer games our 9 year old had programmed which run on Windows only. (At this juncture feel free to speculate at the wisdom of a parent who sends his son to a class which uses Windows).

If you have your original Windows discs it’s free, as easy as any Windows task ever is and works. Mine is Windows XP SP3, but any version through Windows 7 is supported, not to mention many flavors of Unix and, for those unwilling to hack their PC, you can even run Mac OS X from within Windows.

The product is the updated version of the one I ran under Snow Leopard and is named VirtualBox. Created by Sun it’s now part of Oracle and it’s free. Set it up right (the instructions are good but ‘techie’) and you can run Windows in an OS Lion window and cursor directly to that window like any other OS window. Windows runs in its own space and viruses cannot migrate to the OS installation. Several years with VB under Leopard and Snow Leopard have not resulted in any problems on the Mac side. Yes, I still get the inevitable lock-ups on the Windows side.

You can download VirtualBox here; it’s professionally supported and I have found it to be bug free.

Here’s a snap of Win XP running in Lion:

By all accounts Windows 7 is far better than XP or Vista so if you must have Windows and do not want to have to boot into a separate partition or use another machine, this is one way to go. Speed is fine on my Hackintosh and you don’t have to be Einstein to do this successfully. Sound worked out of the box as did wireless broadband. Once I installed the included ‘Guest Additions’ software (it’s under ‘Devices’ in the VB menu) I was able to set screen definition to full screen and the mouse cursor no longer had to be clicked in the Windows window to make it work. Looking at the simply awful font rendering in this OS I can’t help wondering how anyone with any aesthetic values could use this garbage. Whatever.

During the long, rambling installation process, which I had to redo from scratch as the Lion installation trashed my previous VB/Win, I grumbled about Windows to a friend, who is an iPad/Mac babe. Her reply was priceless:

Windows will always be with us! At least it attracts most of the viruses!

Making Lion roar

OS X

Getting rid of the silly things.

Apple’s latest OS, Lion, tries hard to dumb down the user experience compared with its awesome Snow Leopard predecessor. Mercifully, much of this silliness is reversible and I address some of the issues below.

This dumbing down reflects the effort Apple is making to have Lion’s UI more like that in iOS on the iPhone and iPad and I see where they are coming from. Nonetheless, I liked the way Snow Leopard worked, do not propose to use a touch tablet with my Hackintosh and therefore prefer things like they were. If you want to go the touch tablet route for your desktop, try one in an Apple Store first. I found the ergonomics did not work for me; they may be right for you.

Scrolling:

Scrolling has been reversed. Drag the scroll wheel down on your mouse and the screen scrolls up. That works with touch devices but is counterintuitive with a mouse. Go to System Preferences->Mouse and uncheck this box to revert to the old way:

Spell check:

Apps like Mail add the spell checker. It’s every bit as awful as in iOS, uses a rigid rule set, does not learn from mistakes and is insanely frustrating. A friend reports that he wrote that he wanted to “kick some ass” but ended up sending an email promising to “lick some ass” instead. He’s with his lawyers right now.

Disable spell check in System Preferences->Language & Text by unchecking this box:

Finder:

Finder has made many retrograde steps. Color is poorly used, directories hard to find. First, delete the ‘Show all Files’ choice. It’s useless. Right click, Remove from Sidebar.

Then make Finder show the Library directory. Go into Applications->Utilities->Terminal and copy and paste the following into Terminal:

chflags nohidden ~/Library

Hit enter, quit Terminal and go to Apple->Force Quit->Relaunch Finder for this to take effect.

By default, Finder does not show your boot drive, though it does show attached drives. Duh!

Go to Finder->View and click ‘Show Path Bar’.

Click on any Boot directory in the Sidebar and you will see the path at the base of the Finder window. In this example I have clicked on the Desktop in the Sidebar.

Click on the word SSD Boot (or whatever your boot drive is named). Finder will display the Boot directory.

Now click-drag the word ‘SSD Boot’ into the Sidebar. You can now access the boot directory.

Mail:

If you prefer the old look of Mail, go to Mail->Preferences->Viewing and check the top box:

Launchpad:

This one is about as dumb as it gets. The Launchpad icon appears in the Dock by default. Drag it out. The app purports to show an iPad-like screen with all your Apps on the display. Snag is, there’s no way of editing what shows so every Apple app, no matter how obscure or rarely used, shows up. And, in yet another childish knock at Adobe, Adobe apps – or any other apps for that matter – only display on the second and subsequent pages, out of alphabetical order. Too silly. This is a prime example of what I call ‘dumbing down’.

Launchpad. Can you spell ‘Duh!’?

Auto saving:

Apple made a big deal of this feature, long available on just about every app on a PC. Plus, it only works on amateur-hour apps like Numbers and Pages. For heavy duty pros who use Word and Excel, just save your work regularly like you always have or enable auto save. Even Microsoft added that feature a decade ago. Pure Cupertino hype, that one. If Jobs was selling water, his would be wetter and clearer than anyone else’s, I suppose. And 50% more.

Further, if you use TimeMachine for continuous versioned back-ups, it’s hard to see what this feature adds.

Safari:

Safari now wants to open with the last page you were using. Go into Safari->Preferences->General and change the New Windows and New Tabs settings to Homepage.

Then go to System Preferences->General and uncheck this box:

In this way, if you last quit Safari with many tabs open, you will not have to wait for all those pages to be reloaded when you next start Safari. Instead, you will be taken directly to your home page only, with no tabs open.

Mission Control:

I have saved the worst UI error for last. If you liked the ability to display multiple Windows of all your loaded apps as an app switcher (this was named Spaces in Snow Leopard), Mission Control makes sure that you now have a mess to work with. Use multiple monitors as I do and this mess is spread in random order across all three:

Suffice it to say that if Houston’s Mission Control was organized like this, Apollo 11 would still be searching for a landing site on the moon. Just drag this silly icon out of the Dock where it is installed by default.

Do the above and Lion starts to resemble the robust desktop OS which was Snow Leopard.

Why bother even upgrading from Snow Leopard?

  • Because your Mac will be ‘bricked’ earlier if you do not.
  • Because flaky MobileMe will disappear and be replaced by (hopefully less flaky) iCloud Q3/2012. As Snow Leopard and earlier OSs will not support full iCloud functionality, how else are you going to keep all your Macs and iOS device in Sync for Contacts, Mail and iCal?
  • Because new apps will increasingly only run on Lion. Remember Rosetta and PPC apps? Cynically excluded from Lion to obsolete your great PPC iMac.

    • Finally, let’s not complain too loudly. This, my favorite Steve Jobs quote, remains as true today as it ever has.

Lion on the Hackintosh

Hackintosh, OS X

A bit tricky, but now working.

My Hackintosh was resolutely refusing to download Lion from the App Store, telling me the new OS cannot be installed. Despite trying every trick in the book, I was stuck. My Hackster is the original Adam Pash Lifehacker build (click Hackintosh menus at the bottom of the page) and despite many upgrades to hardware – RAM, HDDs, two SSDs, better cooling, you name it – has been rock solid for the past two years, running 7/24. I have little need for the new things in Lion, many of which seek to emulate the IOS experience and to some extent dumb down Mac OS, but am aware that once you fall behind, Apple has every incentive to brick your machine so they can sell you a new one. As I got tired of recycling Apple’s poor hardware and of the related burning smell from its graphics cards, I very much decided to go with OS Lion ASAP to keep my Hackster burbling along, if not boiling.

Time to call FU.

What follows was written by my old geek buddy FU Steve, who was responsible for building the HackPro originally. ‘I’ refers to FU in what follows:

*****

So I went to Thomas’s MacMini (Core2Duo CPU), had him pay $29.99, downloaded Lion and, before hitting install, copied the installation file to an 8gB USB flash card – like the one used in cameras. The Lion license applies to all machines you own – no more Family Pack premia. Thomas uses the Mini as a Home Theater PC only – it’s too lightweight for his heavy duty processing needs.

After experimenting with various methods, I settled on the Kakewalk one, mainly because it provides specific support for Thomas’s Gigabyte EP45-UD3P motherboard. This mobo uses the Intel Core2Quad (Q9550) CPU, clocked at 2.83gHz and while that’s considered dated, your Mac is as fast as its slowest part which, for Thomas, is his mediocre AT&T broadband. There’s no reason to junk the mobo, CPU and RAM just because something theoretically faster on paper is out there. If Kakewalk works as well for you as it does for me, please be sure to make a donation to the author.

You can download Kakewalk here. It supports a very large variety of motherboards and graphics cards; the complete list is here. You will also need Chameleon 2.0 RC5-r1083 – Google it. That’s the small app which makes a drive or partition bootable. With the Lion flash card in one USB slot and another empty 8gB flash card in another USB slot (both originally formatted Mac OS Extended (Journaled), GUID partition), create the USB installer on the empty flash card. Now here’s where the Kakewalk instructions failed me. I restarted and tried booting from the Kakewalk USB flash drive, as instructed. No go. Some research disclosed others were having difficulty here, so I did what follows.

First, be aware that Thomas uses two SSDs in his Hackintosh. Boot and Backup. (His Data and Data backup are on HDDs).

  • I divided the Backup SSD into two partitions – 110gB and 10gB, the latter named Lion.
  • I then used Carbon Copy Cloner to clone SSD Boot to SSD Backup and tested that I could boot from SSD Backup.
  • I then cloned the Kakewalk USB flash drive to the SSD Backup – Lion partition.
  • Next I ran Chameleon and applied it to each of SSD Boot, SSD Backup and SSD Backup-Lion, testing the first and second in turn to make sure I could boot from either.
  • Then I removed the Kakewalk USB flash card from the USB port (essential or the system freezes), restarted and told the Hackintosh to boot from the SSD Backup-Lion partition. Tons of script scrolled by and the installer started.
  • I told the installer to install Lion to SSD Backup (which contains Snow Leopard and all Thomas’s applications) and after about 5 minutes (SSDs are fast) the installation was done.
  • Next I restarted and told the Hackster to boot from SSD-backup and all was well.

What’s going on here? The Chamelon app works off a hard drive or SSD but will not work off a USB flash card. By cloning the USB install data to a partition on the Backup SSD I made it possible to boot the installation ‘disk’ from the SSD. An HDD will work as well, but will be slower.

This is what greeted me after restarting from SSD Backup:

The CPU is actually an Intel Core2Quad, but Kakewalk is fooling the OS into believing it’s a Xeon as the Core4Quad was never shipped in any Mac.

The beauty of this approach is that you are installing onto a drive which already contains all your apps, so no use of Migration Utility is required.

Thomas had me run a bunch of tests on apps and hardware he uses most. Here are the results.

First steps after installation included downloading the Java update from Lion’s Software Update, updating Apple Mail (click), updating SpamSieve for Mail (click-click), installing the updated 1Password (essential for Thomas) and generally getting a feel for things.

What does not work:

First, the OWC Sales/Newer Technology USB->DVI adapter no longer works, meaning Thomas has lost the use of the third Dell 2209WA display he uses; the Hackster has but one Nvidia 9800GTX+ GPU card and that supports only two displays. The third needs the USB->DVI adapter. This will have to await a software update for Lion; System Preferences->Displays still ‘sees’ the third Dell. (See ‘Anomalies’ below).The alternative wireless dongle from Newer Technology does not work, another candidate for a software update. No old PPC apps work – Quicken 2003/5/6/7 (Thomas converted all his Quicken 2005 data to iWork, the least bad alternative, and they are all bad), EyeOne Match for the EyeOne Display2 colorimeter, as discussed earlier here.

Update: OWC has released an updated driver for the dongle and all is now well.

Sleep:

I could never get Sleep to work in Snow Leopard – any version. If you put the computer to sleep using the mouse or to timed sleep (System Preferences->Energy Saver) the BIOS would be reset and the Hackintosh would refuse to restart, requiring a complete boot cycle. As Thomas requires ‘instant on’ functionality, he simply left his Hackintosh running 7-by-24. Very energy wasteful.

Well, Sleep still does not work with the factory provided Lion OS; the BIOS is trashed and has to be recovered on restart. Even worse than with Snow Leopard. But I have finally managed to get it working in Lion – keyboard/mouse or timed. You need to replace the SleepEnabler.kext kernel extension in Lion. To do so, download the Kext installer here – it’s named KextBeast. Then download the replacement SleepEnabler.kext here. Install it. Sleep now finally works. Set your preferences for Sleep in System Preferences->Energy Saver.

What does work:

Sound and wireless broadband (TP-Link card with an Atheros chip emulating Airport) worked immediately.

Photography applications:

  • Lightroom 3.4.1 with Camera Raw 6.4.1 – no issues. Running in 64-bit mode.
  • iPhoto ’09 v 8.1.2 – no issues.
  • Bonjour printing – all Thomas’s printing is wireless. Brother HL-2170W monochrome laser printer – perfect. Hewlett Packard HP DJ90 color inkjet dye printer – perfect. Tested by making a big print from Lightroom. Phew! Real deal breaker for Thomas if this failed.
  • Photoshop CS5 v 12.0.2 64-bit – no issues

Speed benchmarks:

Geekbench – CPU performance:

In OS Snow Leopard 10.6.7:

On OS Lion 10.7.0:

That’s virtually identical.

For reference, here’s Geekbench running on my MacBook Air, the one with the 1.4gHz Intel Core2Duo CPU:

Those running Intel Core-i7 CPUs with 1333mHz RAM can expect a score of around 12,000 with up to 16,000 on the fastest (and costliest) systems.

Cinebench:

You can see how Thomas’s Hackintosh compares with some of the fastest machines out there in this test – here’s the Open GL test. The GPU is an Nvidia 9800GTX+:

And here’s the CPU test – you want to make sure your machine is really well cooled before doing these:

CPU operating temperature:

The key design brief for my Hackintosh was exceptional cooling. Thomas lost several MacBooks and iMacs to overheating. Here’s the recent history of the steady state idling CPU temperature in his machine:

OS Snow Leopard 10.6.0 through 10.6.7 – 107F
OS Snow Leopard 10.6.8 – 115F
OS Lion 10.7.0 – 115F

Snow Leopard 10.6.8 incorporated much of the Lion code and accounted for the 8F temperature rise. Lion keeps it unchanged, so realistically Lion runs 8F warmer than Snow Leopard. That’s never a good thing, but with a case temperature operating limit for the Intel Core2Quad Q9550 of 176F, there’s lots of headroom left. If your CPU is a Core2Duo the operating limit is higher – check it at Intel’s excellent site.

Other useful apps which work fine (nearly all have been reviewed by Thomas here – click the search box at the top of the page):

  • Total Finder – Finder with tabs and split screen
  • Moom – screen splitter
  • HideSwitch – shows invisible system files
  • Firefox 5.0.1 – second rate browser
  • Fingerprint – print from an iPad or iPhone
  • Transmit – with an update
  • Dropbox – what MobileMe should be
  • MouseLocator – flashes a green circle to help find the mouse cursor – see ‘Anomalies’ below
  • NetNewsWire – RSS feed aggregator
  • ImageWell – used for posting images to blogs

Other applications which do not work yet – meaning they probably do not work on genuine Macs either:

  • LogmeIn – remote desktop. Update July 25, 2010 – LogMeIn just issued a new desktop Lion app upgrade and the app now works properly.
  • Realtek Wireless Utility for Newer Technology wireless USB dongle – fixed – new driver installed
  • Newer Technology USB to DVI display adapter and software – fixed – new driver installed
  • SecondBar – shows the menu bar on all displays – fixed – see ‘Anomalies’ below
  • TrimEnabler – garbage management on SSDs – fixed – just re-download and re-install the current Snow Leopard version

Anomalies:

  • Thomas uses Dell 2209WA displays, which come equipped with two USB pass-through sockets per display. These USB sockets have ceased working though I have confirmed that the related sockets on the Hackintosh work fine. There’s a driver update here and once installed the third display comes back to life and the Dell USB pass through sockets become live again! Further, the new driver finally allows screenshots to be made from the related display.
  • The Hackintosh has a built-in Sony SDHC card reader. This has ceased working. However, plugging Thomas’s SDHC card into an inexpensive Transcend USB card reader and plugging this reader into one of the two front USB sockets on the Hackintosh has the card recognized and readable.
  • Re-downloading TRIM Support Enabler and reinstalling it has TRIM working on both SSDs, as confirmed by System Report-Hardware-SerialATA.
  • MouseLocatorAgent – causes jerky mouse cursor behavior, so switched off in System Preferences.
  • AirDrop, Apple’s new file sharing technology, does not work on the Hackintosh, but is fine on other Lion-equipped Macs.
  • Second Bar is a wonderful utility which permits display of the Finder menu bar on multiple displays. There’s an update for Lion, though it does not work on USB-DVI connected displays. The Snow Leopard version is unstable.
  • AirDisplay, which permits the use of an iPad as a second (or third or fourth or ….) display, needs a new driver for the Hackintosh.

Final steps:

With everything working well, I used Carbon Copy Cloner to clone SSD-Backup to SSD-Boot and restarted from SSD-Boot, the default startup drive. I left the SSD Backup Lion partition in place in the event Lion ever needs to be installed elsewhere, or reinstalled. If the drive with the installer fails, Thomas has the SDHC flash card installer which can be cloned to a new drive from which a fresh installation can be made. The beauty of this approach is that a fresh install can be made to any drive. The latter need not contain any predecessor OS.

So if you, like Thomas and I, are a reluctant but resigned upgrader to Lion and use a Macintosh, things overall do not look too bad. I expect Thomas to get an easy two more years from his HackPro.

*****

Thank you FU Steve, for all your hard work in keeping the HackPro current.

This blog post was written and posted from within Lion.

Does a Hackintosh make sense? An addendum from FU Steve.

With the latest iMacs increasingly price competitive and very fast, do the blood, toil, tears and sweat involved in crafting a Hackintosh still make sense? Thomas addressed this at length here. In summary, if you want the last word in robustness, reliability, easy parts availability worldwide and low repair costs there is no Mac, whether Mini, iMac or Pro, which compares with a Hackintosh. Further, modern software ‘builds’ allow the OS to be updated using Software Update, with manual labor only involved at major version changes. If you need the latest in CPUs/GPUs/RAM speed you would be building a Hackintosh with Intel’s fastest i7 CPU, an ATI Radeon HD5970 graphics card and 16-32gB of 1666 mHz RAM. Your all in price would still be less than half that of a MacPro and parts availability/upgradability infinitely better. So it’s a ‘horses for courses’ decision. With the exception of the MacPro, there is no Mac made which I would trust when it comes to reliability under hard use, all failing the test of proper ventilation/cooling with exorbitant repair costs when they break once out of warranty.

Since Thomas wrote that piece, the iMac and Mini have added Thunderbolt high speed data ports; this is Intel’s LightPeak technology on which Apple has a one year exclusive, meaning that PCI-E LightPeak cards will become available for PCs some time in early 2012. Tests confirm that this technology is faster than USB2 by an order of magnitude (meaning ten times faster) and is faster than eSATA. If you are moving large quantities of data – like video files or BluRay movies – this is a worthwhile investment and Thomas has told me he will likely ask me to add a card to the Hackster once disk drives sporting Light Peak connectivity become common and affordable.

The capacious box of the Hackintosh not only provides ample space for cooling radiators and fans, it also accommodates many drives:

Drives in the Hackintosh. All are internal (labels are wrong) except
TimeMachine which is in an external cradle.
