Hello, I have a macbook pro mid 2012 with a GPU intel 4000 and 8gb RAM. when i launch the UE4 editor from the epic launcher, it does not work. when i press the button “begin” it changes the status to “preparing” and go back to the initial state and the editor never appears. I have around of 35GB free in the disc. i don’t receive any error msg. nothig to understand which can be the issue. does anyone have any idea about what can it be?
