Snapshot 13w02a doesn't work in mac

Working on OSX 10.8.2 for me, investigating your crash report...

Same mac version, no crash. Does minecraft have permissions to the folder its running in?

It can be a corrupted jar file, but you should also update your java version to 7 (search on google). Try to redownload the entire bin folder.

I'm also on MacOS and single player works fine. But it crashes when I login to a server. I also added my crash report log.
(edit) It also crashes in single player after a while 😞
