I installed fmp15.0.2 and it crashed during startup. I then realized that I was running an early version of Yosemite and so upgraded to 10.10.5. I restarted but fmp15 crashed again. I wondered if installing under the previous OS was a problem so reinstalled fmp15 but still crashes. This happens whether I try to launch fmp15 by clicking on a file or by launching the application directly. (The database file is on the machine.)
I am using a MacBookAir6,2.
