Vulkan: Loader not found

[j0hnsmith]

Describe the bug

I'm trying to run the cogent hello world example on an arm64 mac. It compiles but doesn't run, I get the output below.

I've installed https://github.com/KhronosGroup/MoltenVK.

Any ideas what I'm missing?

How to reproduce

Run the cogent hello world example on an arm64 mac.

Example code

package main

import (
	"cogentcore.org/core/core"
)

func main() {
	b := core.NewBody()
	core.NewButton(b).SetText("Hello, World!")
	b.RunMainWindow()
}

Did you run core setup as documented in the install instructions?

I hadn't, didn't realise any setup was required. I've run it now and it works as expected, thanks.
