So I installed MonoFramework, MonoDevelop and MonoMac and downloaded the latest version of MonoGame. I tried compiling the samples but they all fail with the same error
Parsing error of #error Unknown platform.
The problem seems to be that for some reason #if MONOMAC and #elif MONOMAC are being ignored.
If I remove the Windows, XBOX and Linux related code and get rid of the #if MONOMAC the code compiles and executes. Has there been a change and should I use something else instead of MONOMAC in my platform check (i tried with __APPLE__ and MAC but neither worked).
Thank you in advance.
It should just work. If you install the MonoGame templates, does it allow you to create MonoGame project for MacOS?
