So, in an effort to get better performance out of my aging iMac (27-inch, Mid 2011, 3.1 GHz Intel Core i5, 32 GB RAM), I did a clean install of Yosemite and reinstalled all my apps. I did notice some areas of improvement, but InDesign is crashing at least once a day now. Today, it crashed when I was placing another InDesign file into a layout. Yesterday, it happened when I was placing an image. It also hangs when I'm exporting PDFs.
I know this isn't a lot of info to go on, but I'm wondering is anyone has a suggestion
