Step 1: Step 1 - IS YOUR HARDWARE COMPATIBLE?

Picture of Step 1 - IS YOUR HARDWARE COMPATIBLE?
For everyone having worried about their hardware setup, there is a website that lists hardware components and whole computer systems:

For computer rigs:
http://wiki.osx86project.org/wiki/index.php/HCL

For individual components:
http://wiki.osx86project.org/wiki/index.php/HCL_10.5.2

Granted the above lists are for 10.5.2 and now 10.5.5, but for the most part the same rules should apply with patches and compatibility.

BY THE WAY
you should be aware of if you are doing this for the first time. The first one is that you should NEVER use the Apple updater to update your installation of Leopard. For instance, if the Apple updater pops up and says that you can update from 10.5.5 to 10.5.6 DO NOT UPGRADE UNDER ANY CIRCUMSTANCES!!! It will brick your machine and you will need to re-install Leopard again.

Step 2: Step 2 - WHAT YOU NEED

Picture of Step 2 - WHAT YOU NEED
The things you need for this project are as follows:

High Speed Internet Connection (Useful if you want the disk image before the end of time)
Blank DVD-R (or two, I'll get to that later)

Nero, or some other program that allows the burning of disk images to blank media
A BitTorrent program such as BitComet or Transmission

A computer with the following attributes:
Processor with either SSE2, SSE3, or SSE2/3 capabilities.
at least 512 MB RAM
at least 9 GB of free disk space
A DVD drive for installation

Once all of the essentials are taken care of, we can get to the nitty gritty. In my personal opinion, this is one of the easiest installations of any operating system that I have ever had experience with. If all of your devices are supported, and your system has reasonable specs, you may expect to be cruising on your new Leopard in under and hour and a half. If you have just the bare minimum system requirements, it may take considerably longer.

Step 3: Step 3 - PREPARATIONS

Picture of Step 3 - PREPARATIONS
Preparations:

Now, for the two practical options you need to download the Leopard distribution. The latest one out on the internet is from a development team named iDeneb. They have the latest Leopard release - 10.5.5, so go to a popular torrent site (I cannot link or suggest one for legal reasons) and if you happen to type in something similar to "iDeneb 10.5.5" you might happen to find what you need. Unless you have a crazy good connection, expect to wait at least half a day for the whole thing to download. It is a large file and will take a considerable time to acquire.

Then you need to burn the .iso file to the blank DVD. I like to use a free program called ImgBurn. You can download it here http://www.download.com/ImgBurn/3000-2646_4-10847481.html?tag=mncol

Step 4: Step 4 - BOOTING FROM THE DVD

Picture of Step 4 - BOOTING FROM THE DVD
tip of.bmp
diagnostic mode.bmp
If youve never booted from a CD or DVD on your system, then follow the outlined steps. If you already know how then just skip the next paragraph.

Insert the dvd into your dvd drive and shutdown the computer. Then whenever the computer boots up, pay attention to if it says anything about boot sequence or BIOS setup in the first few seconds of booting. For most Dell systems that Ive come across the Boot Sequence option can be reached by hitting F12 at startup. For HP it is usually F2. Other BIOSs might be Del or any of the F keys. Then select your CD/DVD drive, and the computer will boot from it after hitting enter.

And now the possible difficulties begin. If you wait a while and let the DVD boot up, it will eventually say something like "Press any key to begin or F8 for options . . ." (I know it isn't exactly that, but it is similar), if you press any key the next screen pops up:
Now, if your CD/DVD drive is still spinning at this point and the light is working, than chances are you are perfectly fine, nothing to worry about. But unfortunately with this particular distribution of OSX86, there are some issues with older hardware. You will need to go through a lengthy process in order to get back on the right track to install Leopard. From what I've seen the problem mostly involves NVidia chipsets, but it could be other hardware that causes its malfunction as well. Here is the website that has the patch, you may be able to find instructions as to how it is used as well. (It involves messing with the .iso file that you downloaded earlier, and you will need some basic knowledge of the Windows command line or Linux Terminal)
The Patch website:
http://ideneb.ihackintosh.net/index.php/lang-en/homepage/58-ideneb-v13-1055-nforce-patch.html

Remember when i said in the materials needed section that you may need 2 blank DVD-R's? It's because if you have this problem you will need to burn the patched .iso to a new disk in order to use it.
The link shown above is part of the iDeneb website. If you have further problems with this particular distro, consult that website and the forums at InsanelyMac.

(Also, when first booting the DVD at the part where it prompts with "press any key . . ." press F8 and then -v in order to boot in diagnostic mode. This may be useful for troubleshooting)

Step 5: Step 5 - INSTALLATION STARTS

Picture of Step 5 - INSTALLATION STARTS
Back to the ideal installation case, these failures are depressing!

A gray screen will load with a cursor or colorful pinwheel in the upper left corner. Then a Blue iDeneb screen will appear

Step 6: Step 6 - LANGUAGE

Picture of Step 6 - LANGUAGE
Then the language selection screen will appear (English for this instructable)

Step 7: Step 7 - FORMATING

Picture of Step 7 - FORMATING
Disk Utility.bmp
Disk Utility 2.bmp
You should now see a welcome screen. Dont click continue yet. Now it gets more complicated. You need to format the hard drive at this point in the installation. To do this, go to the Utilities button on the upper OS X bar as pictured below. Then go to Disk Utilities.
The disk utility will come up. Click on your hard drive (Not any partitions you may have, see below - its in the right hand column) and then click the erase tab:

Click on the Volume Format drop down menu. I always use Mac OS Extended Journaled. You may be able to use another type, but I know for a fact that that does indeed work. Then name the partition whatever you would like, I'm partial to something plain like Leopard.

Once that is accomplished (It may take some time depending on your hard drive size and system configuration) click the red x button to exit the Disk Utility and return to the installation Welcome screen and then click continue.


NOTE: Make sure there is a partition on the left hand side that says "Leopard" (Or whatever you named it). If there is not then go to the Partition tab, select 1 partition, and partition the hard drive properly.


Step 8: Step 8 -SELECT A DESTINATION

Picture of Step 8 -SELECT A DESTINATION
destination.bmp
Then the screen in the picture will appear. Click agree to continue. Then the "Select a Destination" screen will come up telling you where you can install Leopard. It should show the partition and hard drive you just formated. If it does not then something went wrong in the formating process, but don't worry, you can still go to the Disk Utility and try it again. (Please note that in this photo an external hard drive icon is used, unless you are installing on an external drive, a hard drive icon should appear). Click install.

Step 9: Step 9 - INSTALL SUMMARY

Picture of Step 9 - INSTALL SUMMARY
After you click install the "Install Summary" page should show up. VERY IMPORTANT!!!!!

You MUST Click Customize!! If you do not, your install probably will not work. The Customize screen will show you several options that you will need to select or de-select based on your own hardware configuration. If your first install does not work correctly, chances are you need to choose different options in the After you finished customizing click done and return to the installation summary page.

Step 10: Step 10 - CHECKING DVD

Picture of Step 10 - CHECKING DVD
The installer will now check the disk. If you are feeling particularly daring you can skip this process. However, I recommend going through the process at least once. There may have been an error in burning the disk, or the .iso file itself may have been slightly corrupted. As long as the disk hasn't been scratched, you really only need to check the disk once if you need to install Leopard again.

Step 11: Step 11 - FINISHED INSTALLATION

Picture of Step 11 - FINISHED INSTALLATION
Once the installation is complete a green circle with a checkmark comes up saying that the Installation was successful. You will need to restart the computer (I think it may do it automatically if you are not around) and after it goes through the Darwin Bootloader, another Apple loading screen appears:

Step 12: Step 12 - ALMOST DONE

Picture of Step 12 - ALMOST DONE
Now all you need to do is set up the Leopard Basics..Guess what. Then your done!! - that is if all of your hardware is supported. If it is not, I suggest checking out these sources:

Step 13: JUST UPGRADE

Simply upgrade to 10.5.6. Make sure to only download the update not the combo update, using the upgrade software on your new mac!
siman8806 years ago
on step 1 you said not to update through the Apple Updater... is there a different source that you can download it or no?
Haha. That's what I was thinking. I think it's better not to update than to have Apple lockdown your mac (or in this case, your PC). Lol.

little help please When I boot from DVD, press f8, then -v I can see error which says "FireWire unable to determine security mode" Then "still waiting for root device" I have PC with AMD Athlon 3200+ procesor
Try turning off your FireWire ports in your BIOS menu. The FireWire ports are often not recognized properly on Hackint0sh machines. Also, not too many AMD boards are supported so that might be your problem.

LOL if you happen to type something similar to "iDeneb 10.5.5" too funny. What you should really mention is that many of these hackintosh releases are very unstable and require an AZZload of tweaking to stabilize.

will this work with a computer that is not connected to the internet?

PowerISO current versions do not work. The one that I believe does is 4.2, can be found here: poweriso.com/PowerIso42.exe

Did you just rip off someone else's work, or are you the same guy?
THIS IS THE BEST THING IN THE WORLD!!! Now you can have Mac on a PC!!!
is this made for installing leopard on a vista?

thank you first of all , i recently installed the"iDeneb 10.5.5 just to try it in a small partition that i created in my laptop ,to later install it in my desktop pc .on my lap top a was running XP and UBUNTU. ok my question is when i uninstalled the iDENEB and restarted i could not boot in to my windows boot manager and all it said was boot : error how can i fix this . thank you.
You need to use your windows recovery discs (or make recovery floppies (search for xp recovery floppies on the microsoft download center.)) Then boot with the recovery disc, and go into the recovery console. Enter fixmbr and then fixboot and restart. (If this doesn't work, then type them in the opposite order, I'm not really sure which way they go.) This should solve your problems.
conradev6 years ago
you can upgrade to 10.5.6, im running it. Its complicated though because you have to patch your dsdt.aml file. just google on how to do it

Nice 'ible, I have been working on this project myself for awhile using many different versions. For anyone who is having problems around step four i would strongly suggest using f8 and typing -v for verbose mode -s for (safe?) mode and -f for (failsafe?) BUT ESPECIALLY -x which is what solved my endless problems. then make sure you give the gray apple screen time to do its work. cheers, mspark400

Hi there, I tried installing Mac OSX on my laptop. As far as I can tell, I have all the correct specs (consulted a few different sites) and multiple copies of the ISO and Vista recovery discs made up just in case. I was going through, and the screen from Step 4, Snapshot 2 came up. I didn't know at the time that it was a problem, so I left it, thinking it might just have to through it. After about 2 hours, I figured I should look into it some more. I just went and consulted Step 4, but not only do I not really understand what's causing the problem, the supplied link lands me a big ol' 404. Any help at all would be SUPER appreciated!! Please email me: matthewmurley@gmail.com Thanks in advance.

Is this an actual release of OS X from Apple or is this like a Linux Distro made to look like OS X? Also, if it is from Apple don't you have to pay them for a legal copy of OS X? This is sooooooooo cool. Also, in some of the pics, it looks like OS X Tiger not Leopard.

for the patched os x thanx

the link is no good =( can u pleeeezz send me a new link!!!
You spelled "Leopard" wrong. I also don't understand how you get Leopard to install without it being a Mac.
CyberTech2000 (author)  Cartermarquis6 years ago
Oops my bad about the spelling thanks for pointing it out. And ya runtherd99 is right.
Hey kalyway is a better distro try that :D
it's a hacked version of osx, like hackintosh. that's why it installs. it's hacked to run on non-mac machines.
Ok thanks. I get it now.
cool. i was going to try it, but it had compatability issues with my custom built pc
even though it's hacked to work on non-macs, it is still only compatible with intel sse3 cpu's. mine is an amd, so it doesn't work.
CyberTech2000 (author)  runtherd996 years ago
iDeneb the disk I used for the instructable is compatible with amd as well. You have to select the amd patch in the customization step. Many other hacked discs have compatibility for amd as well.
I recommend iATKOS v4a. It's designed especially for AMD processors.It's only 10.5.4, but I've not had problems with v4i.
CyberTech2000 (author)  damurdock6 years ago
Ya I actually agree and also there are tutorials on upgrading it.
CyberTech2000 (author)  runtherd996 years ago
With what hardware specifically maybe I can help you out.
