Hi,
just downloaded Molten 0.19 to test compute shader support using your SaschaWillems branch from https://github.com/brenwill/Vulkan..
I use Xcode 9.2 Macos 10.13.2 and AMD Vega GPU..

other samples run correctly..

MVK_computenbody compiles OK..

but trying to run MVK_computenbody got this error:

can help?
thanks..

Thanks for reporting this. It turns out that macOS/OSX Metal 2.0 does not support the memory_scope feature…so it is being generated in error on macOS High Sierra.

We will fix this in the next release.
