I just did a follow-up bugfix release due to an unexpected dynamic linking on macOS: [Do not assume homebrew installation on macOS · Issue #1246 · haskell/ghcup-hs · GitHub](https://github.com/haskell/ghcup-hs/issues/1246)

`ghcup upgrade` on those systems may be broken. To fix, run the following command in your shell:

```sh
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_NONINTERACTIVE=yes BOOTSTRAP_HASKELL_MINIMAL=yes sh

```
