Hello all, Oh man, I thought this would be the answer, but sadly, it's still a no go for me. I am getting that "Aperture Library cannot be found" message in iTunes as well.
Stats:
I have share preferences set to Always
My "first" aperture library was stored in the default location (internal hdd)
My "real" library is located on a HFS+ formatted external drive
When my first library is selected, iTunes sees it no problems
When my second library is selected, iTunes complains
I've tried deleting the plist for iApps and Aperture, still no dice
I've tried the "create a new library, switch back" method, yep, no dice
I've done all three aperture first aid options
My screen saver can see my "real" library (the second one that iTunes struggles with).
Any other ideas?
