Aperture Albums in iTunes

I had an issue the other day where a couple of my Aperture photo albums weren’t appearing in the photos tab of iTunes, so I couldn’t sync them to my iPad.

The fix turned out to be: select the errant photos in Aperture and then click on the menu item “Photos > Generate Thumbnails”.

Some people recommend “Photos > Update Previews” as well, but it wasn’t required in my case.

Reset iPad Backup/Sync

Several times lately when I’ve tried to sync my iPad it’s failed to complete the backup stage, even after 10-12 hours. If you force-quit iTunes and try again iTunes will skip the backup with the error message:

“iTunes could not backup the iPad “Chris’s iPad” because a session could not be started with the iPad”

I did a little research to find a solution, here’s what works for me:

  • Quit or Force-Quit iTunes
  • Delete your old backup: ~/Library/Application Support/MobileSync/Backup
  • Delete all files from ~/Library/Lockdown and /var/db/lockdown
  • Reboot Mac
  • Reboot iPad (hold Home and Power buttons until Apple logo appears)
  • Run iTunes
  • Select Reset Warnings and Reset Cache in iTunes Preferences > Advanced

Hope this helps someone else.
