License activation error: `Error: [Errno 86] Bad CPU type in executable: 'amplkey'`

When I want to activate the license on my mac mini (m4), it gives the error:

python -m amplpy.modules activate "my_uuid"
$ amplkey activate --uuid "my_uuid"
Error: [Errno 86] Bad CPU type in executable: 'amplkey'

Does ampl not support m4 cpu? Because I succeeded on my m2 macbook pro.

Hi @Cero,

Thank you for reporting this issue. As a workaround, could you please try installing rosetta with softwareupdate --install-rosetta and try again?

Hi @Cero,

We have updated amplkey in recent versions of AMPL and rosetta is not needed anymore as it runs natively on Apple Silicon hardware. You can upgrade your AMPL module to the latest versions as follows:

$ python -m amplpy.modules install --upgrade
