@sowa705 I am working on getting https://github.com/MrJul/Estragonia to work on Mac and, the lack on Vulkan support (in SkiaSharp) is a show stopper. But, wait! You are working to fix my exact problem. I have cloned your PR and am attempting to build the native bits buuuuut, I have no idea how to do that. I will continue Googling but, if you have some guidance, it would be greatly appreciated.

dotnet cake --target=<SOMETHING GOES HERE> --skipExternals=all --supportVulkan=true?

NM. I got it building. Working on testing now...

I was able to build native skia libraries with vk enabled but the rest of the solution is giving me some issues

Same here. I patched your changes on to the latest production release (3.116.1) and it builds but, there is a crash in MoltenVK. I have tested several versions of MoltenVK, all have the same crash issue. I can post a stack trace shortly.

@NicholasFreeman @sowa705 did you ever discover the reason for the crashes?

@mattleibow Not conclusively, yet. In my use-case (Avalonia on Godot via MrJul.Estragonia), it appear to be an issue with the symbols from MoltenVK not being exported/found. I have not had time to get back to it; If/when I do, I will post updates.
