iPhoto access to Aperture library - forcing upgrade after Yosemite
I've just upgraded to Yosemite and unfortunately Aperture 2 needed to be upgraded (at an additional cost).
Assuming I don't want the upgrade and choose to use iPhoto instead, iPhoto still insists that the Aperture library (and app) get upgraded.
***** that you have to pay for the app upgrade even though the OS upgrade is free and in doing so has locked you out of access to your pics until you shell out more money.
iMac, OS X Yosemite (10.10)
