Installing Tiger involved quite a bit of work, and may have taken someone with advanced knowledge of computer software an entire weekend to perfect. Drivers were hard to come by, and it was largely luck of the draw if you were able to get your particular hardware to work with Tiger. Leopard was an evolutionary step forward, automating much of the process and having great compatibility with PC architecture. More modern devices are supported automatically, both through default Leopard software, and from the lovely folks who compiled these hacks in order to liberate OSX for the masses.

This was mostly accomplished because Leopard was meant from the beginning to be used on computers with the x86 Intel architecture. The roadblock keeping OS X from naturally running on any pc is something called EFI, or Extensible Firmware Interface. The EFI that Leopard uses is only tooled to work with Apple hardware, which means that it needs to be patched. The original method of patching was to use a thumbdrive attached to the computer and utilize the terminal to transfer files from the thumbdrive to the operating system files of Leopard. Compared to installing Tiger onto a PC, this method was ridiculously easy and was all that was required to have a successful boot of Leopard. But a better solution is now available, one where no thumbdrive is required and installation is streamlined and so easy that nearly anyone can do it.

Microsoft and Apple rivaling every domain starting from the Operating Systems to the iPods and Zunes. Have you ever thought how it would be to use your Windows on Mac PC. But now its possible to run Windows software on Mac pc, just because all the mac are powered by Intel Processor’s unlike the previous one.

With Apple Boot Camp we can install Windows XP on a Macintosh Computer using the original Microsoft Windows XP installation CD with the product key. After installation, you can start up you Macintosh using either Windows XP or Mac OS X. This can be accomplished in the following steps

Apple doesn’t allow you to install MAC OS X on a Windows PC.But if you are a big fan of MAC OS X and wanna use it then surely you are not gonna buy another apple PC for MAC OS X it will be much better and money saving method to install MAC OS X on a X86 PC. I am sharing the method of installing MAC OS X on a PC (Dual Booting with windows XP)

Apple states the following basic Leopard system requirements, although, for some specific applications and actions (such as iChat backdrops) an Intel processor is required

* Processor must be any Intel, PowerPC G5 or G4 (867 MHz and faster)
* DVD drive (for installation of the operating system)
* At least 512 MB of RAM (additional RAM (1 GB) is recommended for development purposes)
* At least 9 GB of disk space available.

Features of Mac OS Leopard

1- Leopard is a true 64 bit OS and coupled with Intel’s Core Duo chips, it makes this a fast and highly flexible OS.
