Can I replace OS X with Kubuntu just the same, and as simply as, replacing Windoz with Kubuntu?

Anything I need to know, advice? Tutorial? Im have not much experience with Macs. I am well experienced with PC multiboots, but all I want to do here is eradicate OSX, and replace. My first time loading Linux on Apple machine.

HI ERIC!

Thank you!

It should not be that much of a trouble. I've done it the other way (running OSX on a custom PC) but that's a different story. There's some guides around on how to manage this, here's one for you to check: https://help.ubuntu.com/community/Intel_iMac

Apple uses "normal" hardware in thiere machines nowdays. Intel CPU, Realtek soundchip and Nvidia GFX I think. I actually run OSX with drivers gathered from Debian.

Is there a special reason for this change? I think OSX is kinda neat you can get Macports for OSX that will let you install a whole lot of Linux-packages and you can install OSX with a custom kernel. It's called Vanilla kernel and is just more like the one used with most Linux dists. With this kernel you could for example install KDE onto OSX but I'd guess that's kinda messy.

edit: The rEFIt tool is a that will install a bootloader on the hidden EFI partition that is used by OSX. If you don't plan to use OSX, than use another bootloader.

Yea, great reason:
I feel great limitations in OSX, since my Kubuntu laptop died. OSX feels just like, like my skin is too tight.

ok, I felt that way in linux just because I was so used with software not supported in Linux. Got a long history with windows, seems like a bad marriage when I look back on it So I swapped to OSX on my desktop and keep linux on my other machines, they communicate well with each other

Good luck with your iLinux, there was lots and lots of info for different dists on http://mac.linux.be/
