If you have not updated to macOS High Sierra yet, you will have to for FCPX 10.4.1 Having animal of your present Sierra OS could come in suitable. For important projects, I have copy of Libraries on RAID 5 and 2nd copy sometimes 3rd on hard drive. In Finder, go to the drive where Final Cut Pro X Libraries are located, select Final Cut Library and folder, if you use media, and drag them to hard drive. 03 Back up the version of Final Cut Pro X app in Application folder.

When you double-click the App store update button for Final Cut Pro X, the version will replace the version in Application folder. . 06 Extra credit Right before you update to FCPX, empty Motion Templates folder by moving its contents to new folder..
