Mine worked…sorta…for about 2 weeks on 10.8.1. Would crash sometimes while syncing, but I figured it was more to do with web based junk
NOW…it will NOT EVER sync or Compact the file without crashing. I can do work within the program (backing up FREQUENTLY) and get an occasional crash for no reason.
I have had Activity monitor running while working and have found that FTM 2 apparently starts using ALL the available memory trying to compact or sync, IE: it shows at using 102-104% of CPU capacity, then crashes. I have written and sent crash reports in 5-6 times, but after the first one, all I get is the "thanks for reporting." Gonna keep nagging until they fix it. :-)
My largest problem is I NEED TO SYNC them. The web part in the program is SLOW, so I use the website to add sources and the program to enter all the family info etc I have.
