Trying to insall Debian on Mac OS X. If you plan on doing so, familiarize yourself with following concepts: rEFIt, gptsync, MBR/GPT hybrid partition table. And .. prepare to reboot a few times. This is with Debian Lenny CD1 only; amazingly it has no gptsync in default install and its install is completely confused by Macs. Hopefully they’ve ironed it out in Squeeze a bit.
