The wallet works for me on OS X 10.9.2 Maverick. First time it didn't and I got a broken file error or something while downloading with Safari so I removed the software. Rebooted and tried downloading with Chrome and unzipped the file, moved the app to applications and then it worked. Even staking with an encrypted wallet seems to be working although I haven't staked anything yet.
Thank you for info. I downloaded it with Safari, will try Chrome and other moves as you described.
MacOSX wallet works perfectly.Has absolutely nothing to do with Safari/Chrome guys... ::
Maybe it's related to moving application to applications folder. Now it works for me.
