I've got an old Mac G3 that I installed Xubuntu on. I installed it to a second hard drive. It was a great experiment, but I'm to impatient to wait for anything to happen. I did a bunch of updates this morning, as it wasn't hooked up to my network, there were over 250 updates and it took almost 3 hours to complete the update. I would like to revert back to the Mac os. What do I have to do to get rid of yaboot?
