Thats a good question as I'm running 10.9.2 myself & it runs fine for me.
I have it open right now. It also runs on other machines I've tested that are also on 10.9.2
Do you only have the 1 mac to test on?
Are there any others besides you that have this issue?

http://kryptochaos.comUnfortunately only have one mac to test it on, my other computer is a pc and has absolutely no problems with the wallet. I read previously a few users having the same issue as me earlier on in the posts, all had recent operating system, etc. I hope they are still following and read this fix.
