Ok, macs don't really get malware. unless specifically targeted for it. Macs are also very secure, and I really doubt you were hacked.
So question you locked your wallet, and then when you unlocked it crash, that means two things, one that your wallet was never unlocked. Which is the theory I am going with. I do think once you restored from a backup you should click new address and see if that address pops up. It also doesn't contain any fee so did you change your tx fee? I think this is just a freak thing and you have the address sitting your wallet. Unless did you run any java applications from the web, that is the only other way.
Also use -rescan, that will help a lot as well.

PFFT - Macs are less secure than everything exactly because of this bad information that has been marketed by Apple. I do virus removals for a living. OSX is ~15% of the market right now (and that's being very kind) but more than 60% of the virus removals I do are on macs. Mac users are generally clueless about computer security because it's 'well known' that 'macs don't get viruses'. They always seem amazed and confused when I find and remove whatever infection they have.
My advice would be - get a real os (there's nothing wrong with mac hardware, you can run freeBSD or other linux on it just fine). Or if you don't want to bother learning about computer security - get a nice android device and keep your wallet on that.
At the very least - get some sort of security software on your mac and/or some help to track down the infection.
Security software seems much easier for the average user than changing their OS.
