It's over. I quit. I give up. I am abandoning Family Tree Maker for Mac 2. It has completely messed up my tree with it's constant crashing during syncs and merges. I've uninstalled and reinstalled, compacted files, uploaded and downloaded COUNTLESS times.
It keeps doing the same thing. Works for a few syncs and then messes everything up again. I'm switching to MacFamilyTree; hopefully it will be more "Mac friendly".
