MoltenVK throws an exception when built for macOS on x86

[sslupsky]

I built the app with no build errors. macOS Sonoma 14.4.1 OCLP 1.4.3 MP 6,1

When I run the app, it throws an error. Not sure if this is a problem with my Homebrew installation of Vulkan or if there is some other issue. There was no app bundle, just a "ngscopeclient" executable. Is that the normal build output for macOS? Or, is there another step to build the app bundle that I missed?

Are you using OpenCore Legacy Patcher to run an unsupported macOS version (more specifically, a graphics card that does not have native Metal support under recent macOS versions and requires patches)? If so, this is a known issue that I have reproduced and is due to bugs in their patches. I have reported it upstream to OCLP via their Discord, but so far there has been no fix.

I believe it first started happening for me with macOS 14.2, but I might be mistaken here.

Ahh, indeed I am. I started to wonder about that. Thanks for the feedback. I updated the initial post to mention OCLP.

I'll close since this is clearly an "unsupported" configuration and I shouldn't expect anyone to do anything about this.

There was no app bundle, just a "ngscopeclient" executable. Is that the normal build output for macOS? Or, is there another step to build the app bundle that I missed?

We do not have an app bundle yet — this is normal.
