On the arm64 architecture m1, go1.21.4.darwin-amd64.pkg can be successfully installed, and it seems to run normally.

On the arm64 architecture m1, go1.21.4.darwin-amd64.pkg can be successfully installed, and it seems to run normally....I am very shocked.

Is this because of any adaptations made by Go? Going one step further, is it possible to not distinguish the CPU architecture during future installations and just focus on the operating system type?

This is Rosetta 2. It is not Go, it is MacOS.

Thanks. It does seem to be related to Rosetta

If you are running the amd64 Go version on a Apple silicon Mac, it is. That is exactly what Rosetta 2 makes possible. It works for Go and also for most AMD64 binaries out there.

This is because it runs under Rosetta 2. 

The emulation is pretty fast, and it’s possible to detect it both from the GUI of Activity Monitor, than on the command line

ps -p `fuser /usr/libexec/rosetta/runtime | sed -e 's/.*: //' | sed -e 's/ /,/g'`

From inside the program it should be fairly easy too… 

HTH,

Thanks for the useful replay!
