Install OS X86 Leopard on Intel based machine

TRANSCRIPT

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. OS X Leopard was cracked for PC consumption the day of its release. 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. OK, first thing's first. This is a set of guidelines for installing OS X Leopard onto a PC. What you choose to do with this information is up to you, and I am in no way responsible for whatever happens to your machine. 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: o Processor with either SSE2, SSE3, or SSE2/3 capabilities. o at least 512 MB RAM o at least 9 GB of free disk space o A DVD drive for installation

Now that 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.

Preparations: In order to install Leopard, you first need to get the Leopard OSX86 installation disk. Now, the legality of this is somewhat questionable. The general consensus is that there are three ways to go about this, and I will order them in the most painful to least painful:

Become an Apple developer. After several years or decades of convincing Apple Corp. that it would be a great idea to open up their kick ass operating system to the public for use on PC's, you can probably install the now defunct and outdated leopard onto your PC free of legal worries. Buy a Leopard License, and then go and download Leopard from one of a plethora of Torrent websites. So that way at least your giving your money for a Leopard license and choosing to use it on a computer. Even though the license agreement specifically states that you cannot use OS X on anything but apple hardware. Oh well, it happens. Who cares, just download it. This is the most common method, and also the least legal.

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 upwards of 2-3 days 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 prefer using Nero to do the burning, but you may have another program that does a similar job. 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. Here is what a Dell Dimension 3000 BIOS boot selection screen looks like: (The CD/DVD drive is highlighted)

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-nforcepatch.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. Here is a screen that might tip you off that you have a problem:

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) This is the screen (in diagnostic mode) where the failure usually occurs:

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:

Then the language selection screen will appear (English for this tutorial):

Loading Screen:

Welcome Screen:

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. 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.

iDeneb's changelog will appear, click Agree:

Then the following screen will appear 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 continue and the Install Summary page comes 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 Customize screen:

Click Done and return to the Installation Summary Page:

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.

WHOO HOO! Leopard is installing!

Once this is complete a green circle with a checkmark comes up saying that the Installation was successful. You will need to restart the c
