Previously on 11.2.3 I was able to run my OpenGL game targeting my M1 Mac mini as an iPad game. After updating to macOS 11.3 I am now getting an error in Metal. Is this expected moving forward and a sign that we need to focus on porting to Metal sooner rather than later?

-[_MTLFunctionInternal baseObject]: unrecognized selector sent to instance 0x13046dab0

Crashing on:

glDrawElements(GL_TRIANGLES, 6, GL_UNSIGNED_SHORT, nullptr);

Thanks,

Same error
My app is running fine on iPhone but when I deploy on MacOS 11.3.1, it crashes with error

[MTLIOAccelDevice registerDevices]: Zero Metal services found
[_MTLFunctionInternal baseObject]: unrecognized selector sent to instance 0x11de708d0

[General] -[_MTLFunctionInternal baseObject]: unrecognized selector sent to instance 0x11de708d0

Thanks for the reply. I can confirm it still occurs on my app as well with 11.3.1. It seems like OpenGL got broken and I don't know if Apple has any desire to fix it as it was marked deprecated.

It worked fine for running the iPhone app on my M1 MacBook Pro (MacOS 11.4). But after I updating static library (*.a file) or changing CocoaPods integration from dynamic to static, the crashes happened without other changes.

After a few searches, I found a workaround for running on M1 MacBook (not solving the real problem).

Maybe you can try it:

Got to Edit Scheme → Run → Options → GPU Frame Capture.
Change value from Automatically Enabled to OpenGL ES or Disabled.
