The editor on OSX was working for me, but I decided to try the OSX 10.10 developer preview which was fun, but the UE did not work a long with many other features so I did a fresh install of 10.9 again.
I’ve updated all of the software and the OS to the latest version, but when I open the editor this is what I see. I’ve tried normal troubleshooting - restarting application, closing other processes, restarting etc. etc. Is there something I’m missing? I apologize if this is posted in the wrong place.
