The problem is MacOS' ancient bash version.

$ bash --version
GNU bash, version 3.2.57(1)-release (arm64-apple-darwin24)

Almost 18 years old will just not work ;) It's old enough to drive a car and drink alcohol.
If you use Homebrew try pouring a recent version of bash.

See for example [1]. With that it is no problem:

I have no Nerd Font selected in iTerm

$ /opt/homebrew/bin/bash --version
GNU bash, version 5.2.37(1)-release (aarch64-apple-darwin24.0.0)

There are several scripts here that require at least bash version 4. Of course we could rewrite the scripts for zsh (which I use, and which is the default on many systems nowadays), but that would take a considerable amount of time, so please understand that users are just required to use something more recent.
