SOME Adobe programs are compatible with Apple's BS, but they may have issues
And, Apple's BS update sometimes isn't even compatible with itself
I do NOT know if these revert to older links will work with BS
it really could be... that system is not compatible with version ME 2020...
I did it on both my computers - iMAC (2017) and MacBook Pro (Retina, 15-inch, Mid 2014)
(I upgreaded system to BigSur and all apps CC)
and AE and ME work together very well on MacBook
anyway Thanks for Your reply and advices...
Have a good day 😉
