Is there a minimum bash version required? I.e. will it work with bash 3 or whatever ships with macos by default?

There is, the earliest version I've tested with is 4.4.19, but ideally a 5.x version. 3 certainly won't work I'm afraid. If you use homebrew on Mac it's a good way to get the latest bash.
