Yesterday, Apple announced new Macs based on the new M1 chip (also known as Apple Silicon). These will be ship next week. They also announced that macOS Big Sur would be released on Thursday, November 12th.
I have tested all of my apps1 running on Big Sur, on both an Intel Mac and an Apple Silicon Mac. This is how things stand:
macOS Big Sur: All shipping versions of my apps will run fine on macOS Big Sur.2 There are a couple of minor graphical glitches which I will fix in updates. However in my view none of these would be reason to hold off your upgrade. Expect updates to all of them (some long overdue), but not before the release day.
Apple Silicon / M1 chip: All current shipping versions of my apps are Intel-only. They will seamlessly run on Macs with an M1 chip via the Rosetta 2 emulation layer. I will release Universal versions (that is, for both Intel and Apple Silicon Macs) of all my apps in future updates.
If you’re taking the plunge with the new OS, I hope you enjoy it. I’ve found it stable in my testing of the preview builds and it gets a thumbs up from me.
If you run into any problems with my apps on Big Sur or your new M1 chip Mac, please let me know via firstname.lastname@example.org.
