Unreal Editor 4.9.1 keeps freezing at 35% of initilization

I have only just downloaded Unreal Engine for the first time after deleting Unity because Unreal Engine looks much better. I downloaded it and clicked on launch and it said it was initializing then every time it gets to 35% it crashes. I have uninstalled and downloaded again but this has not worked. I have a MacBook Pro so not a “gaming/game development” computer but it worked in Unity so I expected it to work for Unreal Engine. Hope someone can help as I want to start developing games.

Hi GameCore,

With the editor/launcher closed, try this:

  1. Navigate to the “Go” menu and press Command + Option to reveal the “Library” listing
  2. Navigate to Library/Application Support/Epic/UnrealEngine/4.9/DerivedDataCache/)
  3. Delete the “DerivedDataCache” directory
  4. Try launching the editor

Let us know if this resolved the issue.

Thanks
