I'm dual-booting Mac OS X 10.6 (soon to be 10.7 ), and I'd like to access files on my Mac partition from my Ubuntu system. I intentionally set the same username and password for my Ubuntu system as is set for my Mac system so that I'd be able to access files in both partitions from both OSs. However, I was trying to import my music into Rhythmbox and it said I didn't have permissions to access ~/Music (in OS X partition).
