Hi Hoping someone can help as I'm getting to end of tether. I have an old mac mini which I updated to Yosemite a few Weeks ago. A couple of days ago my iphoto said the library needed updated which I clicked on but it seemed to hang so I force quit. However i restarted the mini and opened iphoto but it opened like it was new. No photos i Checked and the iphoto library still existed (and judging by side it's complete. 200gb) however it wouldn't let me reimport it. Thankfully I have time machine but when I go back. Regardless of date the restore button is greyed out and I can't go back. So I tried the alt and command whilst opening and asked to repair the library. Which seemed to work. However it said 140k pics to be imported. Finally 101k did import but only in 2 events. Fine, i selected them and asked to autosplit. After several hours it completed but it's a mess. A lot of the photos are triplicated. Photos are in wrong events entirely and some of the photos appear to be "faces" type images. Ie zoomed in close on a face. Also I'm missing 30k images/videos (got a message saying 3k images couldn't import (most appeared to be video files) My whole iphoto library is now a mess and I have no idea How to fix it. Can anyone make any suggestions. Even if it is to sort time machine so I can roll back a week. Hope you can help.
