Any particular reason why NCC doesn't launch on Mac anymore? NIS seems to be running just fine.

When I'm trying to launch it, the last line of console just says "INFO: NEM Community Client - NCC 0.3.2-ALPHA shutdown..."

Also, how can I back up my wallet? Would really like to know this before I will receive my 1 million NEM   Or is it enough if you just remember your wallet name and password?
