Err... slightly perplexed there Tad.
MacOS is the Apple OS. "MacOS Vista" is the nickname some give to Lion (MacOS 10.7) as it is just plain awful compared to the former versions. This is what i have installed now and was wanting to use Ubuntu as well. The installation process being pretty hermetic to the uninitiated i just don't know how to go about it, and apparently Ubuntu has become even more complicated to install on the most recent generation Macs and there's very little info available on the web... even in Russian
