"Faster video encoding. Encode video faster in Final Cut Pro, Compressor, and third-party video applications on Mac computers using M1 Ultra or M2 Ultra."Well, exactly!Meanwhile, I understand there are a number of features in Sonoma that will not appear in the version running on M1 or earlier. This was noted in a review I saw somewhere online. They're still selling the M1, but it seems they have already decided its headed for 'obsolete.' Nice...

"Sonoma also brings us our first feature that can only work on a subset of Apple Silicon Macs. MFI-certified assistive hearing devices can be paired directly to Macs, but not to Macs with a vanilla M1 inside. You'll need an M1 Pro, M1 Max, M1 Ultra, or any flavor of M2 chip to use this feature; the vanilla M1 is not supported."
