MacosGoMacos Problem Overview
I upgraded to Go 1.18 on Mac 12+.
'go build' fails with errors like:

Macos Solutions
Solution 1 - Macos
As per the comments this was caused by an old version of golang.org/x/sys (mentioned in this issue). Fix is to update with:
go get -u golang.org/x/sys
Solution 2 - Macos
As documentation mentioned,
- The easiest way : run
get -u golang.org/x/sys. - Manual : git clone the repository to
$GOPATH/src/golang.org/x/sys.
