Error: failed to splat Microsoft.VC.14.29.16.10.CRT.x64.Desktop.base.vsix

I am using MacOS Ventura 13.4.1 on M1 processor.

When splatting, I received a message:

I hit this too. It is because MacOS file system is case insensitive.

[evmar]

It's not clear to me if the 'splat' operation is only handling case, or if it's doing other links beyond case.

[Jake-Shadle]

It's only creating symlinks to deal with a multitude of casing issues within the SDK, if you have a case-insensitive file system you need to pass --disable-symlinks so they aren't created. I'd accept a PR to detect this for MacOS if the code was reasonable and didn't pull in dependencies, but this project was never intended to support MacOS (I didn't even know they had case-insensitive file systems) so I won't be doing that myself.

[evmar]

I think when I read through the docs (and peeked into the code) before, I wasn't clear on the relationship between the 'splat' operation and whether disable-symlinks was solely a case thing or necessary for some other behavior. Rereading it now, I think what confused me is that I read "By default, symlinks are added to both the CRT and WindowsSDK" as saying something like "splat creates symlinks from the output dir to the WindowsSDK", which I now understand it doesn't.
