An inexpensive Mac Pro mouse

Mac Pro

This one is a winner

My desktop Mac Pro, a 2010 model upgraded with dual 3.47GHz Intel 12-core CPUs and 96GB of memory, has long enjoyed the company of a Logitech G500 gaming mouse, which remains available. As I have better things to do with my time than destroy brain cells I do not game, but that mouse, after almost a decade’s use, remains a perfect performer. It’s wired and tracks and clicks perfectly, showing no signs of deterioration after over 3,000 days of daily use.

But the other Mac Pro, which is my movie server, is a different story. That 2009 machine, again with upgraded CPUs, controls over 40TB (!) of disk storage on which reside all sorts of DVD and BluRay movies, all instantly accessible at the click of a mouse using DVDpedia. Well, that’s a bit of an overstatement. For years I have been using an RF Microsoft mouse, one of those with a dongle attached to a USB port, and things have gone from bad to worse. First, in this application, you must have wireless so that there are no wires to trip over. Second, scrolling must be dead smooth if you are to page through a lot of movies on those evenings when there is nothing else to do. And while the pointing and clicking functions of that mouse are as good as it gets, scrolling has gone from bad to unusable over the years, so much so that I resolved to explore alternatives.

I settled on a MacAlly bluetooth mouse – no dongle. It paired instantly and using the adjustable scrolling speed setting in the relevant System Preferences window, it points, clicks and scrolls perfectly. The mouse-to-Mac Pro distance is some 10 feet, with the TV screen hiding the computer. The Microsoft mouse has been relegated to the box in the corner of the garage with the black beetles, perennially in search of cheese. I should throw it out but we have developed a relationship over the years, and it’s not like it’s a disposable ex-spouse. The Mac Pro uses a dated bluetooth card which peaks at 802.11n and that’s all that is needed.


The MacAlly bluetooth mouse.

The MacAlly mouse uses two (included) AAA batteries. I use it on a brown wooden semi-matt finish coffee table, as above, no mouse pad, without issues. Unlike the Logitech G500 – no lefties – the MacAlly is ambidextrous. The small rectangular button below the tilting (sideways scrolling) and very smooth scroll wheel switches sensitivity between 800/1200/1600 DPI and I have found that the 1600 setting provides the smoothest pointer movement in my setting. Plus, you can get it in white finish, in addition to the usual black.

Be aware that this mouse is not very tall, unlike the gaming mouse linked in the first paragraph, so all day use may not be that comfortable. But for occasional use with my movie sever it’s fine.

Recommended, and at $20, what’s not to like?

A note on improving Bluetooth reception: If your Bluetooth reception is marginal, characterized by a delayed response of the cursor to mouse movement, a Bluetooth receiver like this helps. Because my Mac Pro is hidden behind the TV screen, the internal Bluetooth receiver receives a weak signal. I simply attached that external $10 Bluetooth receiver to a USB cable and routed it to the base of my amplifier which is in line of sight of the mouse. Problem solved. For $5 more the receiver even comes in a 5.0 version (the cheap one is 4.0) which confers enhanced sensitivity if needed.

A handy Apple ProRAW converter for the iPhone

iPhone, Technique

Getting Apple ProRAW into Lightroom.

One of the nice features of recent iPhones is the option of taking pictures in Apple ProRAW, Apple’s uncompressed and relatively unmanipulated photo format.

What prompts this piece is the excessive default sharpening of JPG images by the iPhone. As a colleague has pointed out, this has been worse and worse since iPhone 4.

The snag is that my Lightroom is version 6.4, and as I have no need for later ‘enhancements’ or the annuity toll they bring, I have not ‘upgraded’. Nor do I need a cloud-resident version of LR open to Adobe’s potential piracy and fee extortion. My LR is bought and paid for – once. But it cannot import Apple ProRAW files from the iPhone.

Wanting to compare the Apple ProRAW files with JPG I needed to get the former into Lightroom, and found that one way of doing this quickly is to connect the iPhone to my Mac Pro, logging on to iCloud Photos. That’s at iCloud.com, not Photos on your local drive.

After selecting the desired image, click and hold the mouse pointer on the file to be downloaded and you will see:


Downloading a RAW as DNG.

The resulting DNG file can now be imported into Lightroom. In my case the JPG was 4mb and the DNG (which is an uncompressed version of the RAW file) came in at 26mb. But, heck, storage is cheap.

The differences in compression and the related artifacts are very noticeable. First the DNG file needed +1.4 stops of exposure increase to match the JPG. Here are enlarged center sections:


JPG on the left.

You can do this in batches in iCloud Photos. Highlight selected files using the shift or control key and download as above.

The DNG files can now be sharpened as deemed necessary in Lightroom, avoiding the excessive native sharpening in the iPhone for JPG images.

Jony Ive on Steve Jobs

iPhone

A sad anniversary.

Steve Jobs died ten years ago today.

Here’s the tribute from his chief designer, Jony Ive:



The power of curiosity, the desire to learn rather than to be right, the willingness to take risk. All the dictates for a successful life are there.

Louche Long

Hall of Shame, Macintosh

Taste and money rarely mix.

Apple has had several justly famous advertising campaigns, from the ‘1984’ ad where an athlete hurls a sledgehammer at a movie screen in a theater filled with automatons, to the ‘Think Different’ series which adulated original thinkers. But maybe the most beloved was the long running ‘I’m a Mac and I’m a PC’ with the comedian John Hodgman as the nerdy and lovable PC-using klutz and, well, Justin Long. Long portrayed the oh! so cool Mac user and his smarmy, condescending, hipster presence did nothing to endear prospects to the Apple brand, for it was Hodgman viewers tuned in to view. One of the best known ads had PC swathed in bandages head to toe, explaining that his multiple crashes were the cause. Another had him on the shrink’s couch relating how unloved he was. Hodgman simply nailed it.


Nerd and hipster.

Before examining the new Intel ads claiming their CPUs are superior to Apple’s new M1 – a CPU which is universally lauded as redefining the realms of possibility in Macs – it bears to relate Apple’s history with CPU makers. The Motorola 68000 family in early Apple ][ computers could not hold it own, Motorola falling behind the performance game, and gave way to the IBM G3/4/5 series. Capable performers, these suffered from high heat output and, when Steve Jobs asked for a cool running successor to the G3 in the fabulous Powerbook notebook, IBM gave him the G4 which did a more than passable imitation of a toaster. It ran that hot. So Steve started the team working on converting the product line to Intel’s CPUs and did so successfully until …. Intel started repeating the errors of Motorola and IBM. Slow development cycles, loss of competitive position, we had seen it all before. But Apple, as always looking down the road, had an answer, having been sub-contracting design and development of its iPhone and iPad CPUs to ARM with whom the company increasingly adopted a tailored approach, not willing to rest on the laurels of a commodity product suitable for all.

This exercise culminated last year in Apple going whole hog and developing its own M1 CPU which not only derived from the state-of-the-art A14 in the iPhone, it also spanked the competition on performance (high) and power use and heat output (low). It was such a success that Apple has started migrating its notebooks and the Mac Mini to the M1 and later this year will do the same for the iMac and Mac Pro.

So Intel, always a day late and an idea short, felt it had to strike back and hired the louche Long, ever willing to prostitute his C-list Hollywood credentials, to talk up the advantages of Intel’s latest (very late) and (not so) greatest CPUs. And they got it so wrong, it’s comical to behold. Not only is Long still smarmy and condescending – characteristics as tied to the actor as the sneer is to Donald Sutherland – it’s really quite unclear what he is going on about.


See what I mean about Long?

AMD Radeon GPUs

Mac Pro

An element of future proofing.

For an index of all my Mac Pro articles, click here.

Apple simply cannot leave OS X alone. An OS that was perfectly solid with the Snow Leopard iteration back in 2009 continues to see annual ‘upgrades’ which add nothing but useless bells and whistles. And with OS X High Sierra (10.13 – 2017) Apple made the last version of OS X which worked with Nvidia GPUs. Nvidia and Apple had parted company a while back and Nvidia decided that the small user base no longer justified coding of drivers for later versions of OS X despite having some of the best GPUs made. Then Apple insisted on adding its Metal GPU technology meaning that from OS X Mojave (10.14) no Nvidia GPUs would work. A solution looking for, and finding, a problem.

So why care when OS X High Sierra works well? Because increasingly app makers are coding for Metal, and if your app is one of those and is in need of an upgrade, you are stuck with migrating to a recent model GPU from AMD/ATI.

I have not researched this in great depth but the AMD HD7950 is known to work well as are later versions. I bought a used 3gB HD7950 on eBay – it was fraudulently advertised as a later R9 280, so what else is new with eBay – and it works well in High Sierra. Here are the comparisons from HWCompare:


Nvidia GTX980 4gB vs. AMD HD7950 3gB.

My tests on my Mac Pro 2010 confirm that the AMD card – it ran me $220 – is marginally slower than the Nvidia/EVGA GTX980 in use, but as I do not do heavy video processing that does not concern me.


Unigine video tests. The upgrade to a faster CPU is irrelevant here.

Nova returns similar performance comparisons:


The GTX980 returns 2640.

Static power consumption, measured using a Kill-A-Watt meter, is 225 watts, compared with 252 watts for the Nvidia card. That rises to 460 watts with a BENQ 32″ 1080p display while running Unigine Heaven. That is well within the power handling of the Mac Pro and, more importantly, the 200 watt maximum power draw of the AMD GPU is below the 225 watts available to the card via the PCIe slot (75 watts) and the two motherboard cable feeds, one 6 and the other 8 pin. Those provide 75 watts each for a maximum of 225 watts. The AMD card is very quiet and there is no start up whirr, unlike with the Nvidia card. While the seller stated the boot screen works (my MacVidCards modified GTX980 provides a boot screen on its DVI and DP ports, not on the HDMI one) that is not the case. I could not get boot screens on any of the MDP, DVI or HDMI ports. Oh! well ….

Should you ‘upgrade’ to an AMD card? Well, if your latest apps insist on Metal and you want/have to install OS X Mojave (10.14) or Catalina (10.15), you have no choice. Only AMD GPUs will work. Does the AMD card work with the latest OS X, Big Sur (10.16)? It’s too early to say.

Adding 4K to the movie Mac Pro:

My motivation was different. Having added a big screen LG OLED TV a couple of years ago to the home theater, I wanted to deliver 4K video to the display which is mostly driven from a single CPU 2009 Mac Pro which is a robust and reliable file server as well as offering internet access to streaming services like Netflix and Amazon Prime Video. But the HDMI card in that Mac Pro is an ancient GTX520, limited to 1080p. Thus I have been using an Apple TV4K to deliver 4K streams, but that’s not an especially elegant solution as you have to switch between sources. That machine is running OS X Yosemite (10.10 – 2014) and has no need of Metal technology. So it occurred to me I could both future proof my 2010 Mac Pro by installing an AMD card and at the same time switch the GTX980 over to the 2009 movie Mac Pro where it will happily deliver 4K definition (3840 x 2160 in the 16:9 aspect ratio, compared with 1920 x 1080 in 1080p). That would allow sale of the AppleTV4K as all movies would be streamed through the Mac Pro and no input switching would be required. The home screen looks like this:


The Mac Pro movie server home screen – all icon driven. DVDPedia – at top left – catalogs movies on the server.

I use a small app named Img2Icns to generate icons from images found on the web.

HiDPI

When Apple migrated its screens to the Retina Display icons shrank to a quarter of their original size, making them very hard to see and click. Most external monitors, like a 4K TV, do not recognize the HiDPI tech built into the displays on Macs, so HiDPI has to be enabled to show icons in a decent size while not affecting 4K definition in 4K movies. HiDPI scaling can be enabled by starting Terminal (in Applications->Utilities) and typing the following (works with OS X Mavericks 10.9 or later):

sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true

Hit enter, type your password, hit enter again and reboot. HiDPI is now enabled. Go to System Preferences->Displays, click on ‘Scaled’ (you may have to hold down the Alt key on your keyboard) and HiDPI options will now be shown. Click on 3840 x 2160 (HiDPI) and your icons will revert to regular size. You can verify that you’re getting the right resolution by clicking the Apple Menu in the top-left, selecting “About This Mac”, then the “System Report” button, then clicking “Graphics/Displays” in the list on the left. You will see something like this:

Displays:

AV Receiver:
Resolution: 3840×2160 (2160p 4K UHD – Ultra High Definition)
UI Looks like: 1920×1080 (1080p FHD – Full High Definition)

If you decide you want to revert the change above, just use this terminal command:

sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool false

SwitchResX:

If you struggle with getting the right definition and frame rate in System Preferences->Displays, install SwitchResX, a small, inexpensive utility which allows you to set both. I find 24fps is inadequate for some movies and with HDMI on a Mac Pro (which supports HDMI 1.4, not the faster 2.0) you can increase the framing rated from 24fps to 30fps, which works well. I have it set at 3840×2160 which is 4K and 30fps.

Conclusion:

So if you need to add Metal/Mojave et al compatibility to your Mac Pro a late model AMD card works well and needs no special drivers. An older Nvidia card (GTX680 or later, but no later than GTX980) can be used to stream movies in 4K definition, a definition also supported by the AMD card. However, the Nvidia card is limited to OS X High Sierra (10.13) or earlier.
