Re: Installation, Debian 12, iMac G5, USB thumb drive => “Your installation media couldn’t be mounted. “

Joe:

In regards to your Ethernet not working in OS X, have you tried
manually setting the speed and duplex settings?  You can do this either
in System Preferences or with ifconfig.

You can also try just resetting the interface:

sudo ifconfig en0 down
sudo ifconfig en0 up
