Cannot run on Mac: Mono does not support System.Windows.Forms in 64-bit
Got these errors a lot. A Long Log full of this error many times over: Here is a shorter version of the log:
64-Bit Mode Errors: "The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at all"
"System.InvalidOperationException: WinForms_SeeInnerException ---> System.NotSupportedException: Specified method is not supported [ERROR] FATAL UNHANDLED EXCEPTION: System.InvalidOperationException: WinForms_SeeInnerException ---> System.NotSupportedException: Specified method is not supported"
Startup never happened. When running the 32-bit architecture mono mode, no errors ever display but CAMM does not start, and just uses ~96% of my CPU power until I force quit Mono.
So neither 64-Bit mode or 32-Bit mode CAMM work on Macs. Not good. Anything that would fix this? Or is this just on my end?
BTW: I am on MacOS High Sierra 10.13.6, and tried using Mono 5.18.1 (V.S.) and 5.20.1 (Stable) with CAMM, with no success.
Here is the code making this bug happen as well:

why was this closed?
I've done some in-depth research and experiments on Mac OS a little while ago, and discovered that Apple recently removed support for all 32-bit applications from their OS.
This leaves only the option to use 64-bit, and as the error above alludes to; and as I discovered from further research, there is no support for a 64-bit version of System.Windows.Forms (or rather System.Drawing that it depends on) for Mono/.NET Framework applications on Mac.
This basically means CAMM will not be able to officially run on Macs. At least not right now and possibly not for a long time.
There was however a third party project I came across that was said to (partially) implement System.Drawing (to enable System.Windows.Forms) for 64-bit Mono on Mac OS. This may be something that I'll look into for the future, assuming that Mono does not add the 64-bit support any time soon.
