I'm trying to open old 2012 FCPX events and projects--no luck. Is there an app or procedure that will help? I know there used to be a method--and maybe an app from Intelligent Assistance? No more? Doomed?
FCPX does not have to be in your Applications folder to run, so you can put the older version in another location. FCPX has been 64 bit for a while, older versions should work to an extent in Catalina, I'd assume.
