Sort of a mini review. Using it at home on my MacBook Pro 2015 Intel Machine. Big Sur on M1 was fine ( if not great ), mostly because M1 is extremely fast. But Big Sir on x86 was slow, really slow. I am in the group that reported Big Sur was slower than Catalina, and Catalina was slower than Mojave. That is with both the OS itself and Safari. So Big Sur was not a smooth experience for me. Monterey so far brings back…
I heard the same from a friend. But my 2012 Air won’t get it. So I’m stuck on Catalina, as I can’t downgrade to Mojave.
