HI I just updated to Big Sur and now final cut X does not open. Earlier I had updated to the latest Os and lost PS5 and Microsoft Office 11 (both those and a few more do not open) I purchased this iMac second hand, on the basis of additional software and of course the iMac itself After these updates it seems I am running into a big loss :( I tried to copy these softwares from the iMac on to my MacBook Pro ( which is even older) but to no avail How can I get at the least FCP X to work? I am mid edit of my short film and a work project All assistance will be appreciated.
