Hi snopein,

This bug has been reported as UE-41890. It appears to be a conflict with Apple’s Metal. Are you running or . Running the latest Mac OS may resolve the issue for you.

Also, in the mean time, if you’d like to get acquainted with UE4, you could download and install UE4.12 which does not require Metal to run.
