2. Mac Photos Has Attempted To Repair The Library

Pam Bush upgraded her Mac to the latest version of OS X, but her Photos library is full of black thumbnails, rather than tiny images. The Mac consultant who handled her upgrade told her it was a bug, and she needed to “rotate every image manually.” “Not going to happen in my lifetime,” Pam writes.

This typically happens when you have imported the photos accidentally using the COPY option rather than the ADD option. Thus, LR is looking in the folders where the COPY was placed, while you are looking in the folders where the original was placed. Re-importing the photos is simply not the answer. It is the wrong thing to do. Photos has attempted to repair the library Photos Library.photoslibrary but is unable to open it. The most common cause of this is a permissions problem. How to fix: Apple recommends to reset SMC. Shut down your Mac, and hold Shift + Ctrl + Option + Power button for about 10 seconds, with your cable plugged in. Click on the power button and wait for your Mac to start up. Try resetting NVRAM or PRAM. Your Mac will load straight into recovery mode. (If recovery mode doesn’t appear, restart your Mac and try pressing the keys again.) In OS X Recovery, click the “Disk Utility” shortcut to launch the Disk Utility here. Select the drive or partition you need to repair and click the “First Aid” button.

The consultant is technically correct: iPhoto and Photos rebuilds previews if you rotate an image, which can be done in Photos in the All Photos view by selecting Edit > Select All and then Image > Rotate Clockwise or Rotate Counterclockwise, and then the opposite after the rotation is complete.

However, for a large photo library, this is a lot of wasted time and effort, and might mask other problems in the file structure. Instead, you can rebuild thumbnails or repair the library, depending on the software you use.

For iPhotos and Photos alike, quit the app, then hold down Command and Option while launching, and keep them held down until you see a dialog.

In iPhoto, you’re prompted with the Photo Library First Aid dialog, and can choose among a number of options, including Rebuild Thumbnails. Select it, and click Repair. (Earlier versions of iPhoto had the Rebuild Photo Library dialog with two thumbnails options, and others that could be checked off at the same time.)

Photos removed any options: when it’s launched with Command and Option held down, you can opt to Rebuild or Quit. Rebuilding performs all maintenance operations and shows you the progress as it goes.
