I have recently downloaded UE4 on my Macbook pro and I have been experiencing crashes every-time I try to work on environment building on a brand new project .
I have also tried uninstalling and installing but it has also crashed .
My specs are :
2.8 GHz Intel Core i7
16 GB 1600 MHz DDR3
251 GB
Unfortunately I was not able to file the report as every time it lags at submission and I have to force quit .
I installed on another Macbook however to test if the issue is on my machine but it also crashed as I tried to environment build and I got this code .
