Most stable PT software for 2020 I5 iMac 11.1OS
 

I Just purchased a newer refurbished I5 iMac as I wasn't sure when the latest compatibility with the new M1 chip was going to happen
(days ago it turns out... sigh... ) I'm leaving PT11.3. and just purchased a "new" perpetual license. Not knowing the newer PT OS I figured a 2020 I5 iMac would be better suited than my 2012, now it looks like compatibility issues all over the place. I haven't downloaded any PT yet. Ideas On the most stable for the newer I5 iMac 3.3 GHz 6-Core Intel Core i5???
Thanks!
