The most likely reason for a Mac Glass compilation error is using Xcode 16 to build an older version of JavaFX (anything before PR #1812 was integrated in May of this year). Xcode 16 enabled a new check which caught an old type mismatch error in GlassTouches.m.
If that’s what you’re seeing you can either grab the latest master or just cut out enough code in GlassTouches.m to get it to compile. The event tap that drove GlassTouches was disabled years ago so it’s all dead code. The May PR removed it entirely.
