Installing Mac OS X Leopard on your Pc...easily...

Installing Mac OS X Leopard on your Pc...easily...


This tutorial was made by me in order to show everyone on the site how to install the latest version of Mac OS X Leopard (10.5) on your normal Windows Pc and run it as your main OS side by side with Windows Xp or Vista. Using this method you will be able to install Mac's native bios, while keeping yours perfectly intact. This is to allow mac to upgrade normally without having to re-download and re-install Mac each time! However, there are two paths you can take, one being much easier than the other, and in my opinion, more fun.

The choice you have to make right at the very beginning is to decide whether you are going to be using your current Pc or not, if so it will be slightly if not much more challenging as you may have to buy new parts in order to have Mac work successfully. The other option, of course, if to build a brand new Pc with all the correct parts that are 100% Mac compatible, which is what I did, however, first I will explain how to correctly install it on your current Pc.

If you plan on building your own, new, Pc, skip down below to the bold text.

As I said, I will be explain how to setup Mac on an existing rig first...so let's begin. First you should note that I will only be explaining how to install this on recent Intel processors first, it is possible to install Leopard on AMD processors too. However I figure most people here have bought a Pc or did the right thing and already have an Intel processor ready to go. (NOTE - If the demand is high for an AMD CPU installation revision I will make it, but only if completely needed).

A newer Intel CPU is preferred, but not needed. We will now check to make sure your CPU is compatible. (I can almost assure you that it is if you purchased it within the past 5 or so years). We will do this by first, if you haven't already, downloading Cpu-Z here. Once downloaded, unzip the file, open the folder, and run the cpuz.exe file. You now need to look for the "Instructions" label and in the text box to the right of it you need to find the code "SSE3" (see pic below). If it's there then your good to go, if not, your Mac image will need some modifications. "SSE2" is also a substitute for "SSE3"...but you will need a different disc image. If you don't see either of the two codes...well hate to break it to ya...but you need to upgrade from your grandparents old Flintstones computer in order to proceed (may I recommend my setup in bold below). You may now go on to read the rest of the tutorial..


My Setup:
-Genuine Mac Pro case that I bought on ebay and modded to fit motherboard in..
-Intel Q6600 Quad Core
-4gb of Corsair ram
-Intel D975XBX2 (Bad Axe 2) Motherboard
-Gigabyte ATI Radeon HD 2600 Pro 
-2 150gb Western Digital Raptor X hard drives striped in raid 0 for speed
-Antec 850w power supply
-Fan Cooled (too lazy for water cooling mods)

Now the plan for this system is to be able to install Mac on this system in an upgradeable way.. For starters you are going to need to download a pre-patched hacked version of Mac OS X. Go to your friendly neighborhood torrent site and download one. For you SSE2 people be looking for the code in the title of the torrent (NOTE - A tip for this is to google "leopard 9a581 *your code* torrent" -AND DON"T BE AN IDIOT AND INCLUDE THE "* *" IN YOUR SEARCH!) and SSE3 do the same.

[url=http://www.google.com/search?client=safari&rls=en-us&q=leopard+9a581+sse2+torrent&ie=UTF-8&oe=UTF-8]SSE2 People[/url]
[url=http://www.google.com/search?hl=en&client=safari&rls=en-us&q=leopard+9a581+sse3+torrent&btnG=Search]SSE3 People[/url] (If possible I recommend Brazilmac's patched version for SSE3)

Once found your going to need to burn the .iso file to a DVD+R DL disc (I don't believe it will fit on anything else). Might I suggest using ImgBurn to burn the disc, as I have had no problems with this in the past and its very good for burning discs providing you burn them at x1 speed. Download ImgBurn from my server below.

ImgBurn: http://disk.mac.com/knightmare214-Public/The%20360%20Ocalypse/Programs/Windows/imgburn.exe?disposition=download+4062

Once burned insert, restart computer, make sure boot from CD/DVD is enabled in BIOS and when alerted by a DOS boot prompt type:

-v -x

followed by enter/(return on a genuine Apple keyboard). This will start up your Mac install in Verbose mod allowing you to install properly. Once Verbose mod is started (which should only take a few seconds) you will be greeted by the normal Mac splash screen (a gray screen with the Apple logo in the middle). AT THIS POINT EXPECT A 15-20 MINUTE LAG TIME FOR THE DISC TO READ YOUR SYSTEM HARDWARE!! If your screen does not proceed to setup after approximately 15-20 minutes or the Apple logo suddenly has a cross through the middle of it..well....I don't know what to tell ya other then to go check your hardware, make sure it's all Mac compatible and if not either download a new version of OS X, edit the current one you downloaded, or buy new hardware. To know for sure if it's a hardware issue, go here and here check to see if your motherboard and graphic cards are on the list. If not post here before buying anything and I'll try and help you out!

NOW WAIT! BEFORE YOU EVEN THINK ABOUT CONTINUING! I KNOW YOU REALLY REALLY WANT TO INSTALL RIGHT NOW BUT THERE IS ONE MORE THING FIRST! At the top of the screen is the Mac menu bar. Click "Utilities>Disk Utility". We are now going to format the drive, so make sure you have either backed up your current windows partition or don't care about it, cuz at this point it's gonna be deleted. Now here's how were gonna do it:

-In the sidebar to the left, select and click the hard drive you want to install Mac to
-Above the main window in the middle select the "Partition" tab
-Okay, click the drop down box under where it says "Volume Scheme"
-Select 1 partition for now (you will be able to change this as much as you want after the install, so don't worry about it too much for now)
-At this point feel free to name your partition. (If you can't figure this out then just give up now Mac is too 1337 for you)
-Lastly, click Options at the bottom and choose "Master Boot Record" as the partition scheme
-Now your almost ready to install, so you can click the red button up in the left hand corner of the window to return to the installer

This is the final step for all SSE2 users, not because I'm tried of teaching you, but because my fingers are starting to fall asleep from typing and I don't feel like writing more if I don't have to. Also if in the past 8 years as of tomorrow you weren't able to upgrade your processor to SSE3 (I believe it only costs like $40 for a low end SSE3 CPU), you are either retarded and work at Burger King and don't have a high enough salary to buy a new CPU, or you are skilled enough to continue on with a SSE2 CPU still and can simply go find a tutorial to learn to upgrade Mac on your own (in other words I'm just too lazy to double the size of this post). BUT, back to the tut. In the installer you can now just follow the onscreen directions and select your new partition as the install destination. Before you click "Install" though you should see a "Customize" button, click it, and deselect "Additional Fonts", "Language Translations", and "X11". These are useless files to most people and will not only decrease your installation size and time by up to a gigabyte but also keep your hard drive nice and speedy for a while longer because it isn't weighed down by useless files. Finally, click "Install", wait 30-90 minutes for it to install (hopefully not 90...if so....then.............wow), and SSE2 users enjoy. SSE3 users, I got a bit more for you to install a genuine version of Mac and make your computer an actual Mac rig!

Feel free to stop reading any time now SSE2 users....you're just wasting your time! :biggrin:


We are going to install Mac's native "BIOS" as an overlay your current BIOS. Just as a quick explanation, you will boot your original BIOS then the BIOS will load the Mac BIOS (called Efi) from a separate hidden partition, then booting to Mac. However, this will all happen with minimal to no speed decrease in boot time. So now download the modified version of Efi from my server below.

Efi Pack: http://disk.mac.com/knightmare214-Public/knightmare214/EFI%20Pack.zip?disposition=download+590

Now on a normal Mac Efi is booted the exact same way it is on a modded Pc, from a separate special partition, called a GUID partition. A GUID partition is special because it will allow you to make the partition, then using a compression algorithm decrease its size when not being written to. This will allow the computer to read from the partition faster than normal, making it an acceptable method for a boot device. You don't really need to know that, I just thought you might be curious of what your about to do to your computer. Okay, in order to do this, open up "Disk Utility", you can do this by opening finder in your dock first.


In the left side bar click "Applications" then in the main window scroll down to the bottom and double-click "Utilities". Again, in the main window, right-click and open "Disk Utility". I had you to do this to explain something to you really quickly before installing Efi. If you right click your partition and select "Information" you will notice something such as "diskXsY" where "X" stands for your drive number and "Y" stands for your partition number. Look at the following image to be able to visually comprehend what I'm trying to get across.


Okay, assuming you have already downloaded the Efi Pack from the server, unzip it if you haven't already (in Mac you can do this simply by double-clicking it and it will extract to the same directory as the .zip, most likely Leopard's default download directory, /Users/**YOUR USER NAME**/Documents/Downloads/ - this can be found by opening Finder and in the left sidebar clicking "Documents" and then in the main window opening "Downloads"). Once extracted navigate into the "pc_efi_v80" folder and find the file named "boot_v8" with no extension and drag it to your desktop. Now insert a usb drive, any one will work cuz all we need to put on it is boot_v8. Just be aware that we do need to format the usb drive, so back up any important data on it first to another external drive or a disc NOT THE CURRENT MAC PARTITION.

Now that the usb drive is in and the file is set, go back into Disk Utility. Your newly connected usb drive should be visible in the left column of the Disk Utility menu. Select it, click the "Erase" tab, and in the drop down box below the tab select "MS-DOS (FAT)" and in the text box enter a name you can easily remember (keeping in mind it will all be in caps), I'm gonna use "NIG" (as seen below), then click the "Erase…" button to continue.


Next drag the boot_v8 into the usb drive, which if not before, should now be visible on your desktop. It will be labelled with the name you chose and have an icon similar to a white floppy drive. After dragged to the icon, double click it to be sure the file copied. If you see if in there you now have my permission to insert your modified Mac install disc and click the Apple icon in the upper left hand corner of the screen. A drop down menu will appear and click "Restart". Once your screen turns black the boot will commence. As soon as you see the Mac splash screen, begin to hold down the Option key (I believe it's Alt on a Windows keyboard. This will start up what you may refer to as a Mac boot menu. You should see an icon an icon resembling a DVD, click it and the Mac installer will begin again. Once started, like before, open "Utilities>Disk Utility" in the menu bar. Select your hard drive in the left sidebar, select the "Partition" tab. Like before, open the Volume Scheme drop down box and once again select two partitions, you can select multiple ones, however, if you want to follow this tutorial word for word, just select one for now and modify it in Disk Utility after complete install. After the number of partitions is selected and customized (i.e. - named and sized correctly), underneath the graphical partition information is a button that says "Options…". Click it and make sure you have GUID checked off. If not this will not work and you will mess up this entire process and you may actually have to start from the beginning of this tutorial. Then click "Partition". After partitioning you can close the window (the red button in the upper left of the window) to return to the installer. Next, check to be sure your usb drive is connected and in the menu bar click "Utilities" but instead of "Disk Utility" this time we are gonna click "Terminal". Consider this the Mac version of cmd...however, unless your a Windows master/nerd (like myself and probably a lot of other people on the360ocalypse.com forums) you will likely be using it a hell of a lot more than cmd. Okay remember how I told you about disk identifiers before, well this is when you need them. You are going to be using these identifiers to be able to write the Efi to the GUID. So to reveal the disk identifiers in Terminal you need to type the following :

diskutil list

It should look something like this when you're done (assuming you named the 1 partition you made "Mac HD"):

disk0s1 = EFI
disk0s2 = Mac HD

Now at first glance, you will see that a partition called "EFI" already exists. Okay you may want to strangle me right now, however, let me explain. Mac is smart, and whenever you format a main drive it automatically creates a hidden partition called "EFI" in order to easily install Mac onto your computer again without having to primitively flash Efi to your hard drive. The problem is, Efi has a kernel of its own, which just happens to be unreadable on a regular Windows Pc, that's why we are putting our own modified version there instead. You may now ask, "How was Mac running before then without Efi?", well it was technically running a hidden program in the background (the Unix under pinnings - called Darwin) in order to get it running, therefore bypassing the Efi boot. Apple doesn't use this method by default because you just saw how easy it was to install it to a regular Pc. Okay, now to copy over the boot_v8 file. Copy this into Terminal hitting enter/return after each line (remember to replace "NIG" with the name of your usb stick and also replace disk0s2 with whatever partition you are installing to):

cd /Volumes/NIG/pc_efi_v72
./startupfiletool /dev/rdisk0s2 ./boot_v8
dd if=./guid/boot1h of=/dev/rdisk0s2 bs=512 count=1

For you it might look something like this:

cd /Volumes/*your drive name*/pc_efi_v72
./startupfiletool /dev/rdisk*drive number*s*partition number* ./boot_v8
dd if=./guid/boot1h of=/dev/rdisk*drive number*s*partition number* bs=512 count=1

Now to finish everything up we are going to unmount the drives before doing the last command. So close Terminal (red button), open Disk Utility, right-click each partition individually and the click "Unmount". Once done to each partition close Disk Utility again and then open Terminal again. You need to input one last command:

For me:

dd if=./guid/boot0 of=/dev/rdisk0 bs=400 count=1

For you:

dd if=./guid/boot0 of=/dev/rdisk*drive number* bs=400 count=1

Okay, you can now close Terminal (red button again) and continue the installation, just remember to click "Customize" before clicking "Install" and deselect "Additional Languages", "Language Translations", and "X11".

Alrighty then! We are now done! I'll let you go ogle your new Mac. And...well...out of pure shame and disgust from actually wasting my time typing this tutorial for random people I hardly know for almost the past 2 days straight when I could have been out with my girlfriend, gone to the mall, caught a movie, watched some porn, or actually have hung out with my annoying family I am off to kill myself....
Naw just ****in with ya....been great....I'll have more Mac tutorials within the next week ready for ya...but almost DEFINITELY not this long!

If you wanna share this with any of your non-premium friends feel free to send them to the link below....however don't post this in the non-premium section because...well....modded Efi is not the most uhm....legal thing in the world! :biggrin:
Anyways enjoy! And If you have any problems or questions post below!
