I am still on Mojave and will be until I am forced to upgrade. Wondering if I should skip Catalina altogether.
I will wait until at least version .4 of Big Sur. Over the years I have noticed that .4 means the kinks are ironed out.(and then the whole thing starts over again...).
Leaving the 32-bit world means $1200 to replace obsolete hardware, so I am not in a hurry.
I liked the shiny pill style(fake 3D) of MacOS best.
what hardware? the mac itself? (just curious of what you're referring to)...
i've never seen any black & white proof of that (the 'version 4
' myth). every version of every OS (beta, or final), has bug fixes, tweaks, and sometimes new bugs. all OSes, at any moment, are a work-in-progress. so you dive in if & when the time is right, and move forward. the kinks are always being ironed out.
still, no harm in waiting (and if '.4' is your moment, then '4' it is).
