"MOL (Mac-on-Linux) is an open source project that lets
Linux PPC users run the Mac OS on Linux. The project has been
around in some form since 1997 and although I had heard of it
before I really never even gave it much thought until I installed
Yellow Dog Linux on my PowerBook Ti.
Now keep in mind that I didn't really expect too much, well I
guess that I mostly expected it to be a royal pain in the ass to
install and according to Yellow Dog, "Setting up Mac-on-Linux (MOL)
is an advanced operation and not recommended for those new to
Linux." I have to disagree, MOL was super easy to install and only
took only took a few minutes of my time."
