Macs are designed to function best with Mac OS X and the associated iLife software (iPhoto, iMovie etc.) but they can happily run Windows or Linux. Rather than change a Mac to the another operating systems you can run Windows using an emulator (Xp, Vista and 7 - use "Sandbox").
But for professionals that want more out of excellent hardware, Linux has tools for most - without the need for "Appstore". So, i run MacOS one one partition, have installed "REFIt" that enables triple boot: MacOS, Windows and Ubuntu Studio. I have installed some more eyecandy Ubuntu, music and video editing software, and this can access the MacOS HFS file system - and even fix it (install all the "hfs" tools). But things that I like, such as the Docking, is installed, but the top, shared menu line that changes for the window that is active, has been replaced by a "Windows-like" menu.
The "ext4" filesystem is aparently more robust than hfs. There are some issues with the using the journalling in hfs from Linux, so be careful. Otherwise, things like email should be able to use the same files. I can "see" all my MacOS files from Linux, and all the Windows files - and when I need a MacOS tool, it is just to reboot and run MacOS - or Windows (this is usually just emulated in "Wine"/"Vm").
You cannot without erasing your hard drive and installing Mac OS 9 from scratch. Even then Mac OS 9 may not run on modern Mac hardware because Mac OS 9 needs the ROM chip to boot. Modern Mac OS X hardware uses EFI to boot the system instead of a ROM chip to boot. Mac OS X v10.0 - Mac OS X v10.4 support Mac OS 9 applications and can run them, you just need to install the Mac OS 9 compatibility program which can be found on the Mac OS X Install CD.
The second name of Mac OS X v10.4.5 is Mac OS X v10.4 Intel.Mac OS X 10.4 was known as Mac OS X Tiger.
Yes. The disc will need to be formatted before you can install Mac OS X. This is probably not the question to which you wanted an answer.
Mac OS X 10.4 (Tiger) needs to be purchased as it is not possible to update from Mac OS X 10.2.8
Mac OS X is an operating system released by Apple Inc. It is designed for Apple branded computers, which is why you will never see a Dell, or an HP computer run Mac OS X. There are only two important versions of Mac OS X, Mac OS X Server, and regular Mac OS X. Mac OS X server was designed for servers, while regular Mac OS X was designed for most computers. The current version of Mac OS X (10.6) is named Snow Leopard.
To upgrade from Mac OS X 10.4 (Tiger) to 10.5 (Leopard) you will need to buy a boxed version of Mac OS X 10.5. If you have a Mac with an Intel processor you can go straight to Mac OS X 10.6 (Snow Leopard) which is a cheaper upgrade option.
Yes, it is. Any type of MacBook that comes out now is a Mac OS X. The most recent version of Mac OS X is Mac OS X Lion, coming out soon.
