Tried everything with the App Store today. It shows Updates available for FCP (10.4.10), but the Update button does not work, not for FCP, not for Motion, not for Compressor. Nothing happens. What a pain Apple.
Had to delete FCP (10.4.9) and install from the App Store (Cloud icon.) That installs the whole app to the current version, it just takes much longer.
But why? Why?
