carrara 2.1 and osx 10.2.1 seem like a good combination. fixes your bug and is nice and stable. i have multiple drives and went up to 10.2.3 on one of them but found it crashed carrara a bit, so i'm sticking with 10.2.1 for now. i really recommend having a spare drive to test updates on. it is huge not having to go back and reinstall everything to downgrade the system software.
