Hi Ken,

Your can see the architecture(s) each port is built for with 'port -v installed'. The ones of concern on an Apple Silicon system will have archs='x86_64'.

HI Josh;

   Is it possible to find out what ports that I have installed that
would fail to upgrade due to not supporting the M1 chip?  If, so what
command would I issue so that I could determine the risk involved of
doing that massive upgrade operation?

Thanks,
Ken Wolcott

[ Disabling "+universal" ]

Yes, that seems to be it; thanks.  Now, is there a way to globally
disable "universal" without cleaning every port and rebuilding with
"-universal"?

You don't have to rebuild everything, but there's no getting around 
reinstalling all the ports that currently have +universal, if you want them to 
not be universal. They may or may not have to be built depending on binary 
availability. The command to do that would be:

sudo port upgrade --enforce-variants installed -universal

If you want to disable universal altogether in your MacPorts installation, set 
universal_archs to an empty value in macports.conf. Note that this will make it 
impossible to install some ports that don't support your configured build_arch.
