But for those who are not technically capable, Mac4Lin is a linux distribution that can make your PC look like a Mac. Of course, there are programs that are exclusive to Mac and have not been ported to linux. I have never been a fan of making one OS look like another. However people do things just because they can. So, if this is your thing, try it. (My thoughts: looks like Mac in some ways, but does not "feel" like it though)
The Inquirer: Designed by Anirudh Acharya of San Diego, California, Mac4Lin looks like the real thing. Only instead of a fully blessed by Steve Jobs Leopard OS X under the bonnet, it runs something which is not proprietary and is free.
Mac4Lin supports GNOME 2.26 and is backwards compatible. It is unlikely to appeal to the Linux purist, who probably wouldn't stoop to stick anything like a Windows 7 look on Linux either.
Maybe it is just the fact that one has a OS that resembles a proprietary for free that makes people want to do things like this. I would like to hear your thoughts if you do like to skin your operating system.
