Mac M1 / ARM compatibility?

[marckohlbrugge]

I've installed unused v0.0.2 via homebrew. When I try to run it on macOS 11.3 on a Mac M1 I get the follow error:

➜ unused
[1]    30856 segmentation fault  unused

➜ unused doctor
[1]    30964 segmentation fault  unused doctor

This person mentioned the same problem on an M1 Mac.

Is unused supposed to be compatible with this architecture?

The tool looks great. Let me know if there's anything I can do to help test M1 builds, etc.

Not sure if this is relevant, but running brew test unused returned the following:

Whoops, seems like there's already an issue about this: #34
