Ver 1.1.0.0 is the old MAC wallet, and I don't recall seeing any bug reports for it, so there currently is no 1.2.0.0-beta like there is for windows.

As far as unlocking goes, when you try to send coins it should automatically ask for the wallet password, so no unlocking needed.

The LTC icon has got to go though!!! (this is what happens when stuff gets released without bug testing.......)
