Unreal Editor 4.1 crashes on launch on os x 10.9.2

Launcher starts normally, but editor crashes with report submission form that has no specific info about crash.System specs:

It launched successfully at first, but crashes all other time. May be there some corrupted temp files I can clean?

Hey Kozak,

Sorry for delay in response. Could you attach your log file from crash? Thanks!

Of course, here for editor:

And crash report client:

Thank you in advance.

Looks like it’s having problems reading ~/Library/Application Support/Epic/UnrealEngine/4.1/DerivedDataCache/Boot.ddc file. Could you try deleting whole ~/Library/Application Support/Epic folder and using Verify Install in Launcher and try again? Thanks.

Yes, this solves problem.Thank you, .
