I have recently tried to install UE4.17 on my Mac and for some reason it won’t launch. In the error message it says that my Mac isn’t up to date and that it needs to be OS X Yosemite 10.10.5 or higher. But, my computer is at 10.10.5, so I’m not sure what else to do. Whenever I click the launch button all is does is minimizes the Epic Games window and then does nothing, I’ll open it back up and it’ll say UE4 is busy, but then does nothing. Hopefully that was a good description and if anyone knows what’s happening, please let me know! Thank you so much.
