Unreal Engine Crashes every time I hit PLAY

Hello there.
I am a student from China.
I have been using UE4 for a while already.
Recently I have changed my platform from windows to Mac.
Now I am using UE4 on my mac, however I encounter some freezes and crashes when I am using it.
When I open the engine, I can use it normally, I can edit the scene, edit the blueprint, but when I hit the PLAY button, the engine freezes and I have to force quit it, and restart, so I lost all my progress.

How am I gonna solve this issue???
Am I the only one who use Mac that encountered this kind of problems???

By the way, here is my set up.
Hackintosh i7-4770, 16G of RAM, GTX780 from ASUS.

Thanks!

Hello zhouxiang19910319,

If you are using a hacked Mac OS X then you might encounter problems in various locations. Did you have this issue with your original operating system platform?

Since the hacked version is not an officially supported platform, I suggest you work on your original operating system. Would you mind testing to see if you get the same crash in while in Windows?

Thank you,

Thank you for your reply !
I did not encounter the same issue when I use windows,
I will keep using windows instead of Hackintosh to do some simple projects using UE4.

Thanks!
