Aperture 2 quitting when doing photo edits
I am using Aperture 2 on my Late 2009 27" iMac. OS X 10.9.5 Maverick.
The application quits unexpectedly when making photo edits. (most noticeable if cropping the image). This problem seems to have only recently manifested. I hadn't been doing much editing until today with the new OS.
Is there a compatibility issue with Aperture 2 and Maverick 10.9.5?.
I'm at a loss as my Aperture library is big and I don't know how to move it to a new computer or newer version of Aperture easily.
Is it time to buy a new iMac / Photo edit software?
Thanks
