Rosetta is dying

Mac Mini M4, OS X, Printing

But your old Brother laser printer does not have to.

Extensive reports from beta testers of Apple’s latest desktop operating system – Mac OS 27, or Golden Gate – suggested that the software was robust and reliable, so I updated from Mac OS 26 (Tahoe) to OS 27 the other day …. and promptly lost the use of my USB wired Brother HL-2300D laser printer.

Reading the Apple Community discussion board disclosed that Apple was no longer including Rosetta with Mac OS 27, and that old but reliable Brother printer used Intel era code to do its thing. Meaning it needs access to Rosetta.

Rosetta – some background:

Two CPU generations ago Apple’s hardware was running on IBM G-series CPUs – the G1 through G5. Apple’s notebook, the Powerbook, was widely regarded as the best laptop on the market and was running the G3 CPU. Steve Jobs wanted to up performance by installing the latest G5 but the CPU ran so hot that it was unusable, unless you liked a scorched lap. I recall owning a G5 iMac desktop and, indeed, it put my kitchen toaster to shame when it came to heat output. The fans would race to maximum under the most modest tasks. Not Apple’s proudest moment.

Anyway, Steve concluded that the IBM CPUs were …. err, toast, and migrated the hardware to Intel CPUs. Cooler, faster, cheaper. To aid in the migration Apple developed a brilliant piece of software named Rosetta, after the Rosetta Stone, whose multi-language engravings acted as a Greek-to-Egyptian hieroglyph dictionary. Hieroglyphs could now be understood. Apple’s smartly named Rosetta performed a like task in translating IBM G generation applications to Intel code, meaning that all those old G apps would run seamlessly on Intel machines. The performance penalty was minor and Rosetta ran completely invisibly. A nod in the direction of that old Apple marketing slogan, “It Just Works”. Eventually developers rewrote all their application to run natively on Intel CPUs and the need for Rosetta disappeared, meaning you forever lost the use of old apps which were never rewritten, though those were few and far between.

History repeats:

When Apple started developing its own desktop and laptop CPUs, Apple Silicon, meaning the M1 through M6 range, they crafted a new version of Rosetta which did for the Intel-to-Apple Silicon change what the original Rosetta did for IBM-to-Intel. Old Intel applications would run perfectly well on M CPU hardware, performing the translation task invisibly in the background. The seamless implementation testifies to some serious programming chops in Cupertino. As before, with most applications now rewritten to run on Apple Silicon, the need for Rosetta went away, so much so that Apple warned that Rosetta would no longer be shipped with Mac OS 27. And as that old Brother printer needs Rosetta to work, it ceased doing so.

The fix is simple, as this extract of the Apple Community discussion discloses. Install Rosetta.



From the Apple Community discussion board

The Terminal app can be found in the Utilities folder, and the whole process takes under a minute. And, Bingo!, my old Brother HL-2300D is as good as new. That printer is hard wired to my Mac Mini M4 and is no longer supported by Brother, so the chance that Brother will update the driver for Mac OS 27/Apple Silicon is exactly zero. But there’s no need to throw it away. Further it works perfectly well with dirt cheap aftermarket toner cartridges and I expect to get many more years from mine. Will Mac OS 28 include Rosetta as a downloadable option? Unlikely, but I’m confident some smart programmer will come up with a new fix.

Running old Intel-era applications:

If you have old Intel apps you like and if these were never rewritten for Apple Silicon, installing Rosetta in Mac OS 27 should allow them to continue functioning.

Lightroom use:

The current desktop version of Lightroom is Lightroom Classic. It requires an Apple Silicon CPU to work and I print using a wirelessly connected Epson ET8550 color ink jet printer. There are no issues using LRc with the ET8550 running Mac OS 27.

Logitech G502 wired mouse

Mac Mini M4

Time for a new one.




The Logitech G502 wired gaming mouse.

My Mac Mini suddenly lost the ability to drag and drop files. Given the frequent use of this function and its general indispensability, this fault rendered the computer near useless.

I set about reinstalling the Tahoe operating system – no change – then restored files from my Time Machine sequential back-up. Still no joy.

That left the mouse and trying a basic old Microsoft two button mouse had drag and drop working once more, so the old Logitech G500 had to be replaced. As it had served me well I went with its replacement, the Logitech G502, and stuck with a wired design as that’s one less thing to go wrong and one fewer battery to recharge. At $38 it’s some 50% less than the G500 was 13 years ago, in inflation adjusted dollars, so no complaints here.

Like the G500 the G502 has installable weights to add heft and I loaded up the G502 with all six. There’s also one spare provided. Each weighs 36 grams/1.27 oz, so fully loaded you are adding 216 grams/7.6 oz, which confers just the right heft for my use. Also, like with the G500, the scroll wheel’s click-stops can be disengaged for smooth scrolling, much my preferred setting.

There’s a downloadable app which claims to do all sort of magic things, including changing the color of the LED logo (how dumb is that?). Well, it is a gaming mouse, which explains a lot about the typical user, I suppose. Rather than mess with that I stuck with the well supported SteerMouse which recognized the G502 immediately and programming the several buttons – there are seven – took a couple of minutes. After some use I had to turn down the pointer sensitivity and speed to get the settings I was used to. Simple to do. The G502’s buttons are located in a manner similar to that on the G500 which makes transition easy.

If the G502 lasts as long as the G500 I will be a happy camper.

6 months with the Mac Mini M4

Hardware, Mac Mini M4, Macintosh

A solid machine.


Still tiny.

I paid $799 for my 16gB/512gB Mac Mini M4 six months ago. B&H currently lists it for $744, at which price it’s a great bargain.

I have had no issues, except that I had to upgrade some applications, most importantly Lightroom Classic with its execrable subscription pricing. Still, at $10 monthly with many enhancements since my ancient version 6 running on the Mac Pro it’s not that bad a deal, but I do not like paying ransom money to a huge corporation. I also had to purchase an external enclosure for the four large hard disk drives and for the BluRay reader/burner which were formerly housed in the chassis of the magnificent Mac Pro. Sadly the latter had to be taken to the recyclers, despite being in perfect condition. A sad event.

Complaints? Screenshots take a few seconds to hit the desktop and sometimes they do not arrive at all. Not that big a deal. And rendering of 20-30mB DNG/RAW image files in LRc (from the Leica M10 and Nikon D800, respectively) can take some three seconds whereas the huge 80gB of RAM in the Mac Pro saw this happen immediately. Again, not a deal killer. And despite having only 16gB of RAM I cannot complain about performance which, in most respects, is of similar speed to that of the 2010 Mac Pro predecessor. And LRc loads in 4 seconds compared with 25 seconds in the old Mac Pro which is excellent, especially given my daily use of the application. Given three daily uses that’s a saving of over 6 hours a year.

Though there are 5 USB-C connectors (three of those also support Thunderbolt) I had to buy adapters for all my hard wired USB-A devices – keyboard, mouse, BluRay drive, laser printer, ink jet printer and a spare for a removable SDHC/CF camera card reader or an off site back-up hard drive. That’s six connections so in addition to buying USB-C to USB-A adapters, I also had to buy a splitter cord. All inexpensive.

The Mini continues to reside behind the keyboard on a pull out tray where it is not particularly well ventilated, but rarely gets even warm to the touch. I never hear the fan despite the Mini being some 14″ from my ears.


Nestled at the back of the keyboard tray. Open USB-A
connector is mostly used for reading camera cards.

If the Mini fails there’s nothing that can be easily fixed unlike in the Mac Pro which was an assemblage of replaceable hardware components. But there are no reports of poor reliability so far. And I console myself that the frequent software security updates from Apple keep the bad guys at bay. Yeah, right.

Recommended, as long as you avoid Apple’s gouging for higher RAM/SSD versions where the cost quickly goes ballistic.

Mac Mini M4 after one month – Part VI

Mac Mini M4, Macintosh

It will do, and is fine with LRc.

In Part III I set forth some technical measurements which indicated that the performance of the 2024 Mac Mini M4 was pretty much on a par with that of the 2010 Mac Pro fitted with dual 3.46gHz 6-core Intel CPUs, 80gb of memory and a speedy Nvidia GTX980 GPU. By contrast the M4 Mini has a single 10 core CPU and just 16gb of very fast memory. This testifies not only to the great performance gains realized by Apple with its in house Apple Silicon M4 CPU with its integrated GPU, but also shows just how awfully good that old behemoth, the Mac Pro tower was almost 15 years ago. Sadly, Apple’s planned obsolescence strategy, which saw to it that the Mac Pro was now six generations of MacOS behind, forced the upgrade. Well, that and the aggressive pricing of the new Mini, and my electricity bills will fall!

I now have a month of heavy daily use with the M4 Mini under my belt, much of that with the Apple Silicon optimized Lightroom Classic (LRc – v14.1.1), an upgrade from the prior Lightroom v6.4), so the following observations are mostly subjective.

Start up is much faster at 4-6 seconds compared with 20 for the older version, if I get a beachball it’s maybe once or twice a week, and with previews enabled image-to-image flipping is instantaneous. There’s the very occasional delay of 3-4 seconds for the image to render in full definition but that was also much the case with the Mac Pro.

More significantly, the latest version of LRc adds significant functionality in terms of localized image adjustments with both the Remove and Masking tools well implemented and easy to use, largely obsoleting the more complex variants in Photoshop. Indeed as I hate paying rent I dropped PS all together and made a one-off purchase of Affinity Photo 2 which does all I need on those rare occasions where LRc cannot do the trick.

A good example of the use of these new to me tools is in this night snap of a retailer’s window in Carmel, CA. The host of images I took in that setting all have a common factor which is that the dynamic range is very high, necessitating exposure for the highlights, to avoid burn out, with a post processing need to bring up the shadows. In the case of these ‘before’ and ‘after’ images not only was the shadows slider used to bring up the shadows across the whole image, I then selectively masked the fountain at the lower left to bring the sparkle in the water to life. The difference is, err…., night and day:


Before.


After.

In learning some of these new features I invested in Scott Kelby’s book. It does not cover the recently added Remove/Generative Fill functions but is an excellent learning resource, greatly superior to any video I have seen.

Returning to the Mac Mini M4, it never gets more than a tad warm to the touch, is small enough to nestle at the back of the keyboard tray and performs equally to the old Mac Pro at a fraction of the cost. While there were many frustrations regarding application incompatibility when switching from Intel to Apple Silicon CPUs these are now behind me, though I still hate paying Adobe $10 monthly in rent for LRc. Otherwise, what’s not to like?

Mac Mini M4 – Part V

Matching storage.

In Part IV I wrote about the French company named Polysoft which is providing upgraded storage for the Mac Studio computer, adding that I expect they will expand their offerings to include the Mac mini M4.

That may take a while as they will have to reverse engineer around Apple’s greed, but meanwhile another entrepreneurial outfit has produced an external SSD in a box with the same footprint as the Mini. TechRadar has the story and storage capacities from 512gb to a whopping 8tb will cost from $140 to $1000. That is extremely competitive when you look at Apple’s upgrade pricing – Greedy Timmy wants an additional $800 for just 2tb.


The Orico external SSD for the Mac mini M4.

Orico claims a throughput of 40Gbps which seems unlikely to me, but we should soon be seeing test data.
