I just allowed my studio Mac to upgrade Logic Pro to 10.4 and an OS 10.13.2 Security Update. A client emailed to ask me for some rough mixes of an album project we've been working on for two years. I go to my "Music Projects" drive and there are all six songs with NO Logic sessions in their respective folders. Some rough mixes, that should have been, and were, in the Bounces folders are there but no Logic icon or folder array as there were the last time I visited the project a few weeks ago. I am very alarmed. The two sets of backups I have show the same absence. Of course I did not nor would ever delete critical session files on six songs currently in progress. It is as if the LPX folder heirarchy has become unreadable.
I don't know whether the Apple OS or the LPX update is responsible but I am freaking out that two years work, fully backed up, could somehow be non-retrievable.
Has anyone encountered anything like this since 10.4?
