AGL removed macOS 26

[Matribuk]

Issue Summary

OpenFrameworks projects fail to compile on macOS 26 Tahoe with the error "Framework 'AGL' not found". This appears to be due to Apple's complete removal of the AGL (Apple Graphics Library) framework in the latest macOS release.

Environment

• macOS Version: macOS 26 Tahoe (released September 15, 2025)
• OpenFrameworks Version: latest
• Xcode Version: xcode26 latest public version
• Hardware: Apple Silicon M2

Ooof!
Does that mean all OpenGL functions don't work? Or is it a matter of just removing the AGL framework from the project?

Ahh I see here:
https://developer.apple.com/documentation/macos-release-notes/macos-26-release-notes

But good motivation to get the WebGPU renderer working.

@Matribuk can you confirm that removing the AGL framework from the CoeOF.xcconfig fixes the issue?

This solve the problem:
In the project settings, go to:
"Build settings > User-Defined > OF_CORE_FRAMEWORKS"
then remove:
"-framework AGL"
in Debug and Release,
then recompile.

It can be removed safely and it works in XCode 16.4
