What did you do?

When using the os#UserConfigDir on Macos (Darwin) in the terminal one would expect that the variable $XDG_CONFIG_HOME, if defined, is used but instead $HOME/Library/Application Support is always returned.

This behavior is probably the preferred way for desktop applications, but in a terminal application it gets very confusing when XDG_CONFIG_HOME is set and not used.

What did you expect to see?

The value of variable $XDG_CONFIG_HOME => /Users/peter/.config

What did you see instead?

/Users/peter/Library/Application Support
