I have a Mac Pro (Late 2013 model - 2.7 GHz 12-core Intel Xeon E5, 64 GB RAM, 1 TB HDD running Mac OS X 10.11.6). I open Finale v25, and run it in full screen mode. I am adding articulations over a group of notes. I drag to choose the notes. The articulation "window" opens up full screen and the symbols quite enlarged. I select what I want to add to the notes, hit select. The screen goes black, and now I am staring at my desktop screen with a notice saying Finale has crashed and do I wish to reopen. This has happened 10 times or so in the last 2 hours.
Maybe it doesn't happen while not in full screen mode, but I can't tell. Didn't run it too much not in full screen mode.
This amount of crashing shouldn't be happening...... but it is.
