Problem

vdev fails to build Vector when run on an arm64 Mac. Ideally it should identify the proper platform automatically, this target appears to be aarch64-apple-darwin.

What is the correct target? Obviously the linux in aarch64-unknown-linux-gnu is bogus on MacOS.

[spencergilbert]

aarch64-apple-darwin - updated the description!

[bruceg]

That's weird. The function that generates that string should be generating that string due to a cfg!(macos) guard.

[bruceg]

This may be fixed by changes included in #20949 when that is merged. The problem is that macos is not a valid guard flag and should be cfg!(target_os = "macos").
