MacOS 27 drops Intel support, will be last release with Rosetta 2

With the announcement of an upcoming new macOS release also come the usual changes in which Macs will still be supported. MacOS 27 Golden Gate is an important release in this regard, as it will be the first release of Apple's desktop operating system that will be entirely ARM-only, dropping support for all Intel Macs. It's important to note that Apple will provide three more years of security updates for the final Intel release of macOS, so Intel users won't be dropped like a brick immediately.

Still, the Intel Mac Pro was still being sold all the way up until mid-2023, and I'd be royally pissed off if my expensive 2023 Intel Mac went out of support a mere six years after purchase. They weren't cheap machines, and while you can argue everybody knew the writing was on the wall for the Intel Mac Pro in 2023, it still feels way too short of a supported lifespan for such an expensive, high-end piece of equipment. It didn't sell many units, I'm sure, but still.

In addition, MacOS 27 will be the last release to include the Rosetta 2 translation layer that allows Intel binaries to run on ARM macOS. I have no idea how many important applications are still Intel-only, but I have a feeling that number is going to be relatively small, and will become even smaller as the first macOS release without Rosetta 2 support near release. On top op of that, I'm sure enterprising users will find a way to transplant Rosetta 2 onto unsupported macOS release, and if all else fails, there's always virtual machines.
