UE4 8.4.2 stuck at 10% on initializing

I am running OS X 10.11(beta) (El Capitan) and I am unable to start UE4 (I have tried both 8.4.2 and previous stable release without any luck).
This happens after a fresh install of both Epic launcher and UE4 (this is my initial use so I have never used any previous versions of Unreal Engine either(!)) When trying to launch UE4 loader gets stuck at 10% and UE4 log file looks like it has crached during logging:

[2015.07.19-15.03.44:774] [   0] LogRHI:   GL_ARB_Shader_bit_enconding
[2015.07.19-15.03.44:774] [   0] LogRHI:   GL_AR

Does anyone know a solution to this?

I know I am running a beta of my OS and I am just clinging on to wish that it is not related to my OS…

I am sorry if I have created a duplicate of a previously known issue, I tried looking but might not have known exactly what to search for.

This occurs with me too. I’m waiting Apple launch another beta version. I think this is occurring because add of Metal on OS X.
