Mac Editor Crash
On my Mac, the Editor crashes every 10-20 minutes when I invoke the save command (with Cmd-S), often with the following stack trace:
Is there a way to switch to Metal only in the Editor?

Your last question is related to the crashes you are experiencing... "Is there a way to switch to Metal only in the Editor?" In the Unreal Engine 4.14 Release Notes "OpenGL support is now deprecated and Metal SM4 was replaced by SM5 in 4.13..."
According to the following link List of Mac computers that support Metal your iMac (27-inch, Mid 2011) does not support Metal so you should be working with Shader Model 4 selected for your Preview Rendering Level as it still supports OpenGL.
In your crash log it indicates that the crash is occurring shortly after the message "Warning: Suppressed: Support for running Unreal Engine 4 using OpenGL on macOS is deprecated and will be removed in a future release. Unreal Engine 4 may not render correctly and may run at substantially reduced performance."
While not definitive, I suggest setting your Preview Rendering level to Shader Model 4, if you have not already, and see if that helps reduce the number of crashes.
Lastly, since your computer is not listed as supporting Metal in the link above, I'd suggest working in a version of the Engine before UE4.13 where OpenGL first began to be deprecated. While it may be possible to actually run the editor, the system is technically below spec for versions of UE4 beyond UE4.12.5.
Regardless of this, however, I will continue to work in determining the exact cause of the crash in your second, related post: Another Mac Editor Crash
