Does not work on Mac Mini M1

Thank you for sharing your helpful script!
I tried it on a rented Mac Mini M1, and got the following output:

Flags:

When I run e.g. sysctl -n machdep.cpu.model, the error is sysctl: unknown oid 'machdep.cpu.model'.

I don't know if I can be of any help debugging this since the M1 is only rented for a short time, but maybe you can add a caveat in your README.md that it only works for Intel Macs :)
