What is the source version of Final Cut Pro? I recently downloaded Final Cut Pro Trial and then after using it for a while decided to get Final Cut Pro from the App Store. Whenever I open Final Cut, it still shows as the trial. I think that the problem is caused by the source version in version.plist. Does anyone have any idea what the source version of Final Cut Pro is? It is stored in /Applications/Final\ Cut\ Pro.app/version.plist. Thanks!

Also, if it helps, I am on macOS Catalina 10.15.
According to the App Store, the current version is 10.4.8. Your best course of action is to delete the trial app (or indeed all instances of FCP if you're unsure which is which), and then download the purchased version from the Store again.
