Darwin 1.4.1 brings the snapshots to the level of OS X 10.1. For the first time, bootable CD images are available, for both PowerPC and Intel. Details are here.

Just a thought. 2001-10-08 9:57 pm Anonymous Hmm…I thought the previous Darwin release had bootable ISOs for both platforms, too. At least, I had a booting x86-image, don’t remember if there was one for PPC.
