[MacOS] Unreal Engine 4.14 not starting

Cannot start Unreal Engine 4.14 at all no matter what I do. Have tried verifying, updating Epic Games Launcher etc.
Don’t know what the error means at all, only using a Mac to compile my game, not actually develop it.

Anyone? Are my posts being flagged or something at the very least as I received no response on my previous post either…

Bump again

Does seem that way.

Eggactly the same issue here. I guess no one is listening :frowning:

Hi,

I have added this issue to our bug tracker which can be viewed here:

Unfortunately whilst I am trying to create/find a workaround the current official response is to upgrade to a newer engine version as we no longer support versions as old as 4.14.

Understandable. Is this crash only occuring on High Sierra so far? The only reason I’m trying to run as said previously is just to compile a Mac edition of my game, and later editions will not run due to the low end hardware.

As far as I know yes this issue only affects High Sierra and it appears to be an issue with something Apple have changed.
