Not sure if anyone has a list of tools that work on Big Sur/M1 macs. So far Slate plugs work(except for VMR). Waves plugs work in FCPX without the GUI, Because of the GUI wants to freak out it doesn't work in Logic. I have not try to see if I can disable the GUI yet(if it is possible) in logic. FCPeffects work fine in Final cut, no luck for Red Giant, Neat, and Pixel Film Studios. Let me know if you have any luck with any other tools.
