Did you store backups or make copies of your wallet anywhere? Can you describe your password in general terms e.g. how long it is, what sort of password it is.
Also can you provide the output of running "ps aux" from the Terminal app?
As far as I'm aware nobody has reported malware that is capable of stealing encrypted MultiBit wallets. If there is now one in the wild, we need to find it.
My password is 10 alpha-numeric random digits with Upper and Lower case.
I didn't make a backup of the wallet yet as it's been just one week since I deposited my first bitcoin. I though the backup is more against lost and stolen hardware rather than additional security against hacking, so I was not too concerned about this. Would this actually help at all?
Anyhow, after I've noticed the stolen bitcoins, I've googled the issue and so far have found just another person claiming the same - he is even using Little Snitch, while I'm not, and didn't protect him either, so he is blaming the app.
Here is his post:
http://www.reddit.com/r/Bitcoin/comments/1scd2n/914_bitcoins_stolen_from_multibit_wallet/Could it be that someone could have access to my computer trough the Boing application? I was sharing some CPU power with WorldCommunityGrid for some Cancer Researches etc for the Ripple team... just trying to think what could be the scenario? They still had to hack my password however my concern is someone doing it remotely while Multibit was not open?? Another "funny" detail is that the address of the receiver was actually written in the send box, in case this could mean anything.
Below my ps aux:
