he, I certainly hope you are making jokes, for OS X (pronounced ten) does not use X Windows if you don't install it separately. X Windows is a so-called windowing manager and is very handy if you need to access a server with a GUI, as opposed to the command-line. It is also used heavily in other *nixes. I am in fact sure that you have never seen X-Windows if you are not joking. here are a few examples: http://playstation2-linux.com/screenshot.jpg http://users.tkk.fi/~mfkoskin/ufo/x/xufo-scrshot1.jpg http://www.openoffice.org/screenshots/images/scalc_osx.png Looks just like the rest of windows on your Mac, doesn't it ;-) here is the entry in the Wikipedia: http://en.wikipedia.org/wiki/Xwindows I occasionally use X-windows at work for accessing stuff on my AIX- server, but it is not something for the average Mac-user, I am certain. That is why it is a separate installation I guess. The good thing about being able to run it on your mac now, is that it enables a lot of *Nix-applications to run on your Mac with a lot less effort than rewriting the code, and this is a very significant step. If you really want to try it out, have a go with Open Office: http://porting.openoffice.org/mac/ooo-osx_downloads.html this next link is a must-read too, if anybody is still with me: http://developer.apple.com/darwin/runningx11.html Kind regards, Kim Den 18. okt 2005 kl. 18.49 skrev Chris Kougouleris - CKougar: > It is X for sure ...
