Hey Hachi8833 ..

This is due to goexpect , or rather goterm , only support linux.

I am working on adding in support for more OSes with FreeBSD being first out. Don't know how close Mac OS is to those though and don't have access to any macs atm.

I experience the same limitation with macOS 10.15.4 and Go 1.14.1. Commenting so I receive any follow-up communication :).

[felixgao]

following up as well. I Seem to have a different error. I am using macOS 12.3.1, Go 1.18.3 on darwin/arm64, M1 Silicon.
