[Vm-dev] Mac OS Mojave bug: 64-bit squeak instantly crashes when OpenGL plug-in installed and then used on Mojave

My current goal is to simply restart work on my Squeak tutorials, but with a focus on 3D. Since I’m using a Mac, I’ll need to know more about Metal.

I assume that NeHe-like tutorials will be possible http://nehe.gamedev.net/tutorial/lessons_01__05/22004/ <http://nehe.gamedev.net/tutorial/lessons_01__05/22004/>

Are you familiar with the simple OpenGL morph that Jeroen van Hilst made nearly a decade ago, but it certainly simplified trying to get started with OpenGL. Hopefully using Metal instead won’t be a terrible hassle.


Thanks for responding.

Currently I am porting that plugin to Metal, because OpenGL is deprecated by Apple, and is probably going to be removed in favor of Metal in OS X in the next version of OS X. Recently, I ported the VM window renderer from OpenGL to Metal, and that change was recently integrated, so the OpenGL B3DAcceleratorPlugin not working on the 64 bits version of OS X is technically not a bug. Wait for some more days to finish the port of the plugin (This is where I am working on the plugin: https://github.com/ronsaldo/opensmalltalk-vm/tree/feature/metal_b3d <https://github.com/ronsaldo/opensmalltalk-vm/tree/feature/metal_b3d> ).
