OS: OS X Yosemite 10.10.5
Unreal Engine 4.12.5 AND 4.10.*
Every time I open a project or start a project with Unreal Engine 4.10.1 and above, and after about 1-2 minutes of use (I timed it), the whole computer, not just the engine, freezes for a minute or two and then restarts by itself.
This only happens with Unreal Engine, and I tried with other programs, but it does not happen.
When the computer restarts, all of the apps and browser tabs that were open before the restart are re-opened by the computer. All except Unreal Engine.
It is also important to mention that until yesterday, it has been several months (don’t remember exactly) since I last used the Unreal Engine, and I never had this issue before. Sure it had some “hiccups” or tiny issues that did not cause any crashing or freezing of anything, and it worked.
This is the first time that anything like this happens.
Some additional information:
- Sometimes when the computer freezes, a very strange screeching sound is made, not from inside the computer, but from the speakers/headset.
- I deleted everything for Epic Games, and the Unreal Engine, and re-installed them. However, the same problem occurs.
- I checked the activity monitor while the Unreal Engine is running, after choosing or starting a project, and I could not notice anything unusual for the energy usage, memory usage, or cpu usage. I could not get screenshots either since I cannot predict when the computer will freeze and auto-restart, and it happens randomly between 1-2 minutes.
- I installed the Epic Games Launcher and the Unreal Engine on my Windows 10 partition, and the exact same thing happened as well. Unreal Engine 4.12.5 that is.

Also, I found something curious although I am not sure if it matters.
In the /Users/Shared/UnrealEngine/Launcher/SelfUpdateStaging/Install/ the Epic Games Launcher application has a white circle with a line through it for an icon. Is that normal? Does that mean it was not installed properly?
Also, when I search through the app’s contents Contents/UE4/Engine/Binaries/Mac the CrashReportClient also has a white circle with a line through it. While Contents/UE4/SysFiles/EpicGamesLauncher/ directory is empty.
