Linux beats Windows to Intel iMac
Ctrl+Alt+De1337 writes "The Mactel-Linux folks have now successfully booted Linux on a 17" Core Duo iMac. They used the elilo bootloader, a modified kernel, and a hacked vesafb to boot from a USB drive. No GUI pictures for now, just white text on a black background. The distro of choice was Gentoo, and instructions and patches are promised this weekend."
Of course, with Linux, comes Windows. In the form of emulating it using VMWare (which isn't supported on Mac OS X natively yet), and also with Wine (true, this isn't real Windows - but it satisfies people's needs to run some Windows programs).
MacOS X uses the Mach Kernel, so the initial booting environment is completely different from FreeBSD. You are getting way to hung up on the "MacOS X uses FreeBSD" thing.
