Mid 2011 iMac, 2.7ghz i5, 12GB Ram, 2TB internal, 240GB External Thunderbolt To start, I use an external thunderbolt drive as my boot drive. I did the update to 10.12.2 today and a few things went weird. After the update did it's mandatory reboot, computer booted to internal drive (I never fully cleared the OS from the internal because it took up more room then the external drive has space), so almost everything on my computer had a ? instead of the correct icon. This took me a few minutes to figure out, and then I rebooted and forced it to the external (holding option on boot up). Everything recovered (on the desktop) but my pictures, documents, movies, music folders where all empty. Like, nothing at all in them. I backup with time machine so restoring them wasn't an issue (outside of taking almost 2 hours), but I'm wondering if I did something wrong when setting those folders up that caused the OS to clear them. My internal is 2TB so I store all 4 of those folders on the internal. My main OS and most commonly used applications are on the MONSTER, and everything seems fine with all that. Just curious if anyone has had an issue with the "personal" folders clearing like this. Thanks! --- Post Merged, Dec 14, 2016 --- OH, and one more thing. My Messages history is gone as well. Opened up with zero conversations. I can't figure out how to recover this. It's not a big deal, but would be nice to get those back.
