Hi, Ken. On a 2020 iMac (Intel), it’s been OK through all the update until 11. 2. Now all projects having missing source files which reside on external hard drives, except for my recent 1st/only with 11.2, the source files are there, but edited timeline was gone. So I redid it. All previous 11.2 projects, have missing source files & mostly not showing at all (see screenshot). I reinstalled 11.1 without resolution. Fortunately I saved my finished project for publishing, but any future re/edits may require a start from scratch. Also considering a new Mac in 2026 and run FC on it. I also recently added Webroot anti virus, but can’t see it having to do with missing files. See pre-11.2 projects & 1st 11.2 where the source files show, but timeline was gone & I had to recreate it. I’m a novice with FCPro and use it about once a quarter for simple personal projects. Keith Examples: https://www.youtube.com/@KeithKaters
