Rosetta 2 support discontinuation notice

Following the announcement that macOS Tahoe would be the last version of the operating system that will support Intel-powered Macs, support for Rosetta 2 is planned to be mostly discontinued by late 2027. This discontinuation is going to impact a lot of people who use non-native applications in Apple Silicon Macs, including gaming and computer-aided drafting applications. Apple did indicate that a small subset of functions from Rosetta 2 will be maintained for an indeterminate period of time after the support discontinuation date, but it is unclear whether the non-native applications will work.


I am planning on getting a new Apple Silicon Mac to replace my current Intel-powered MacBook Air, which I have had since December 2019 but is not able to run macOS Sequoia and will be unable to run Tahoe.

Windows XP security is essentially a submarine with a screen door,

Haha! 😀 No problem, though. I never attempt to go online with it. I downloaded the SP1, SP2 and SP3 updates from MS's updates site through Safari.

I have read that the US Air Traffic Control is still running Windows 95 with diskettes.

That is scary!


Around here, for many, many years, Slumberland (a home furnishing's store) had old DOS computers at all of their checkouts. Decades after Windows had overtaken DOS. Their reasoning was (and actually still is for even some major companies) is that it's a dumb OS that's very difficult to hack because it's Internet unaware.


But they finally had their sales/inventory/etc. system redone as a Windows setup. Grudgingly done because they could no longer replace or repair 30-40 year old hardware as station computers died.

Even after Digital Equipment Corporation came out with Alpha-based systems to start replacing the VAX, DEC's PDP business was a very large business in and of itself. That would be like Apple doing a thriving business in PowerPC-based Macs after having started the transition from Intel-based Macs to Apple-Silicon-based ones.

From what I understand, PowerPC is still a Big Deal in IBM's embedded business. Back in the day, the only time I ever got paid to use PowerPC was when it was an IBM running VxWorks. I don't know the current state of affairs. The most recent Mars rovers use PowerPC. But the Mars drone use a Qualcomm Snapdragon, which is based on ARM just like Apple Silicon.


Intel is really only a Windows thing now. Even AWS is going heavy into ARM. I have some projects that can make good use of some of the crazy-powered EC2 hosts, but even those can run on ARM now. You can get a 64 core, 1 TB RAM EC2 host for $5/hour.

You can always choose to stay on a certain platform, for example, macOS Tahoe (or its successor, macOS 27), in order to continue using Rosetta 2 and whatever apps need it.


Apple has stated that Rosetta 2 will continue to be available through macOS 27 (the successor to Tahoe). Given macOS history, we can expect macOS 27 to be officially supported until at least late 2029. Even after that it will remain viable for many years.


Heck, I'm still running High Sierra quite effectively on a couple of Macs, and it was released back in 2017 ... that's 8 years ago.


App developers have had plenty of time & warning to migrate their apps to Apple Silicon. If they haven't done that, the problem lies with them, not Apple.
