Can't navigate Time Machine interface (going backwards/forwards in time) since upgrading to Mac OS X Yosemite Since upgrading to Mac OS X Yosemite, when I open Time Machine on a folder, I can't navigate backwards in time anymore, on any folder. The arrows are grayed out. Usually, this is because Time Machine needs a bit of time to load older backups, but I have given it a few minutes to load and it still does not work.

Strangely enough, the only time that there is no problem is when I restart my Mac. Once I restart, then I open a folder and open Time Machine, then I can navigate backwards in time, almost immediately, too. But after that, no folder that I open in Time Machine in the future will allow me to move back in time, until I restart once again, then I am able to only navigate a single folder.

Does anyone know how I can fix this?

Things I have already tried:


Repair Disk Permissions on Macintosh HD
Repair Disk on Time Machine drive.
Have you given this a try?


  While in Time Machine, press the key combination shift-command-C. The
  front window will show all mounted volumes. All snapshots should now
  be accessible. Select the one you want and navigate to the files you
  want to restore.
