Installing Mac OS X 10.5 Leopard on an IBM x86 - A Step by step Guide

The leaked file (DMG format) has a size 6.56GB, so you need a DVD9 to burn it. Although it can be installed in original Apple hardware directly.

With some modifications, you may also try to run the OSX Leopard on an IBM x86 PC.

The Credit goes to BraizlMac@osx86scene forum who made the original patch to make all these possible.This currently works on INTEL system with SSE3 support ONLY. An AMD/SSE2 patch should come shortly. Use CPU-Z to check the system capability if you are not sure.

Warning: the patch is rather experimental atm, and even your processor supports SSE3, the installation might still fails due to various compatible issues. Also, the patched DVD seems to be problematic, missing the booting setup part, and most likely would render a system unbootable. Most guides online are based on the instruction comes with the patch file, they didn’t actually install it! I did manage to install the Leopard on my own PC and this guide is based on my very own, first-hand experience. I’ll try to make it as accurate and correct as possible. [src : DigitMemo ]

Update: AMD/Intel SSE2 users try this. Need to patch the original Leopard DMG though, no pre-patched disk available atm.

What you’ll need:

  • Optional: Original unpatched Leopard installation disk image, and patch file to enable x86 PC support and strip the image to 4.3G so it can fit on a single layer DVD. This requires access to an working OSX Tiger system, so might not feasible for everyone.
  • Optional but highly recommended: Patched 10.4.10 Tiger installation disk(torrent download). Other Tiger disk will also work.
  • the patched DVD image(torrent download), post install patch file(rs).
  • a DVD burner and empty DVD media
  • a USB Flash Drive formatted as FAT or FAT32, flash memory+usb card reader will also work
  • Computer with Windows installed, HDD with at least 10G free space.

Prepare before installation

1. Optional: If you have the original disk image and an OSX Tiger installation, then use the patch file to shrink it on a Single Layer DVD. Read the instruction before applying. This will require around 15GB free space on your OSX partition.

2. Burn the patched DVD image.

There are many programs can do it but ImgBurn is recommended as it’s small and free, and most important, as the name suggests, its perfect for burning .ISO files. Just select the image file name and burn.

imgburn

3. Optional: burn the Tiger install disk if there is no previous Tiger installation on your PC.

4. Prepare the hard drive.

Create a primary partition(primary is better, but extended logical partition is also OK, see below), , at least 10G, and format it to FAT32. This can be done by Partition Magic or Acronis Director Suite. Both are commercial software. Or, use the free gparted livecd instant.

5. Prepare the USB pen drive

Format the drive as FAT or FAT32, and rename the label to 123. Windows handle disk label’s caps in a different(and inconstant) way with OSX, so using numeric only label names would be bullet proof.

Extract the patch file(files.rar) and place it on the pen drive, it should look like this:

pendrive

If you use other label names, edit 9a581PostPatch.sh and change the second line

PATCH=“/Volumes/123/files/leopatch/”

accordingly.

Install Leopard

Now lets install Leopard.

1. Optional but Highly recommend: install Tiger first. This can be done by inserting Tiger DVD on your computer and make sure you boot from it. Usually that’s done if you press F8 or F12 or whatever key combination to give you the option to choose what disk/cd drive you want to boot from. Or you can always change boot device in BIOS setup. Select your CD/DVD drive. And

Select your language and when the welcome screen shows up

  1. Select Utilities -> Disk Utility
  2. Select your partition that you want to be OS X and go to the Erase tab
  3. For Volume Format, select Mac OS Extended (Journaled), set volume name as “Leopard” (no quotes, case sensitive)
  4. Click Erase. Now the partition should not be grey, it should be black to indicate that it is active.
  5. Close out of the Disk Utility and move onwards with installation.

Use “Customize” option and unselect all packages there. Just install base system. By installing Tiger first, the partition would be properly formatted and activated, which eliminate any potential problem. Now reboot and remove the Tiger DVD.

2. Install Leopard.

Insert Leopard DVD, and make sure to select booting from DVD. The installer will load(it will take a while, be patient). If you have Tiger installed, don’t format the partition, just install it over the Tiger partition. Otherwise, same approach as Tiger installation, use Disk Utility to setup the partition.

Important: Use Customize… button and unselect all packages there. Then proceed to installation. When it’s done, reboot. And make sure that your USB/Pen Drive is connected to your PC.

Patch Leopard Installation

After the reboot, also make sure you do the same step above: Press whatever key combination to give you the option to choose your boot device: Now Select your CD/DVD drive.

When the Darwin bootloader shows up, Hit F8; When you see the prompt, type -s and hit enter. The DVD will now load in verbose mode. Watch for any panics! It should load without a problem (of course, if you already installed, its all good!)

Once the setup is loaded(again, long wait, be patient), select your language. When the welcome screens shows up, select UTILITIES-TERMINAL. The terminal will now open. We will now browse to our Thumb Drive;

In the command line, type:

cd /Volumes/123/files

Lets now run the script. This will patch the installation so it will boot properly:

./9a581PostPatch.sh

Let it run. You can answer yes when removing the ACPUPowerManagement.kext

Reboot.

The Bootfix patch

After reboot, if the system boots into Leopard fine, ignore this part and head to next section to setup multi boot. Otherwise, you might encounter blinking cursor or “HFS+ Error”, follow the steps below then

If you install Leopard without Tiger first, the system might still boot into Windows instead or leave a system unbootable at all. Even the tboot loader trick(see below) wouldn’t work. In this case, you need to repair the installation and setup boot property for it.

  1. Reboot using the Leopard DVD, make sure the USB pen drive is connected.
  2. Open a terminal after everything finally loads.
  3. Find out what disk your leopard was installed on by issuing this command (my machine was rdisk0s2, will use rdiskXsY below, substitute accordingly)
    diskutil list
  4. Active the partition
    fdisk -e /dev/rdiskXfdisk: 0>update
    
    fdisk:*0> f Y
    
    “Partition 2 marked active”
    
    fdisk:*0> w
    
    Device could not be accessed exclusively.
    
    A reboot will be needed for changes to take effect. OK? [n]y
    
    Writing MBR at offset 0.
    
    fdisk: 0> q
  5. Now goto bootfix directory by typing:

    cd /Volumes/123/files/bootfix

    and do the following

    ./dd if=/usr/standalone/i386/boot1h of=/dev/rdiskXsY bs=512
     count=1umount /Volumes/Leopard
    
    ./startupfiletool -v /dev/rdiskXsY /usr/standalone/i386/boot
    
    ./bless -device /dev/diskXsY -setBoot -verbose

reboot

Post Installation: setup multi-boot

2. Now you’re already in the exciting Leopard! After initial setup, load up Terminal(Applications/Utilities) within OSX and type

sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

edit the Darwin time-out flag accordingly:

<key>Timeout</key>
<string>10</string>

reboot and now you can choose Mac OSX/XP/Vista using Leopard’s boot loader.

3. Optional: you can also setup Windows as default OS and use windows’ OS selector to launch OSX.

So reboot and select Windows partition, load Windows. Open a command prompt(if you’re using Vista, make sure it’s running as administrator). Use diskpart to mark the Windows partition active.

  1. Type diskpart
  2. If you have more than one disk, at the DISKPART prompt, type:
    list disk
  3. At the DISKPART prompt, type:
    select disk x
    Select the disk, x, where the partition you want to mark as active in
  4. At the DISKPART prompt, type:
    list partition
  5. At the DISKPART prompt, type:
    select partition y
    Select the partition, y, you want to mark as active.
  6. At the DISKPART prompt, type:
    active
    to active the selected partition and system will boot from it next time.
  7. At the DISKPART prompt, type:
    exit
    to quit the diskpart program

This will mark Windows partition as active, and the system will boot off it next time. If the PC has Windows XP installed, get this tboot(512 bytes only, a revised version of chain0 loader, support multi HDD as well as loading OSX on extended partition) file and put it to the same directory as ntldr(usually C:\), adding the following line to boot.ini

c:tboot="Mac OSX Leopard"

If the PC is Vista only, put ntldr(get one from your XP installation CD), tboot and a boot.ini file to your Vista boot partition, for example

[boot loader]timeout=0

default=c:tboot      [operating systems]c:tboot="Mac OSX Leopard"

Vista will automatically detect and add the Leopard entry on next boot.

Also, for Vista users, you may use bcdedit to add tboot, but the ntldr way is much much more easier. Anway, if you prefer the native Vista bootloader, here is how:

  1. put tboot on Vista boot partition, usually C:\

  2. Open a command prompt and make sure it’s running as administrator and type:

    bcdedit /create /d "Mac OSX Leopard" /application bootsector

    This will retrun a {ID}

  3. Use the command line below to add the tboot, replace the {ID} accordingly:
    bcdedit /set {ID} device bootbcdedit /set {ID}
    path tbootbcdedit /displayorder {ID} /addlast

That’s all. Enjoy the new Leopard!

  1. 1 Leo

    Hi there,
    I really appreciate your posting. I have a question, my friend bought a MacBook after Leopard released, it comes with 2 original DVDs. If I make copies of these DVDs, how can I apply the patch to it? It seems that the patch only works for dmg file, am I correct?

    Best regards,
    Leo

    You can create a .dmg from the DVD on your friend’s MacBook …

    Hi

    I am installing Leo on an ext drive through an xps m1210 1.8 C2D
    When I type in the initial command
    fdisk -e /dev/rdisk2fdisk: 0>update

    I got
    update: Read-only file system
    The same response if I replace the 0> with 2>
    What do I need to do? to get to the fdisk: 2> state?

  6. 6 Bob

    Well I reinstall everything and seems to be fine with the bootloader commands. EFI installed too.
    after the fdisk -e/…command don’t be perturbed if it shows f:0>. just go along has nothing to do with you disk list ie disxsy.proceed with update,w,y,q.
    One thing I do different is I do the disutil unmount /Volumes/x before the cd /Volumes/123/files/bootfix. Work better. Even wrote a command line to use for repeat reinstallation!
    Instead of rebooting with the install cd after the PostPatch, save time and continue with installing the bootloader. Then just reboot.
    If you put the working patched kext for any thing (ie sound, ehternet, video etc ) in the PostPatch ext folder in Brazlmac. Save you having to do the root:wheel thingy later on!
    Enjoy.

    Fun doing it still can’t beat the real thing.

  23. 23 woody79

    I use Acronis OS Selector to choose between “Leopard” and XP. After following the instructions when I choose Leopard it comes up with:
    HFS+ Partition Error

    Does anyone know why and if so how it is caused.

    23
  24. 24 nikRbokR

    Bob… i got the uphuck version of Leopard (iATKOS v1.0i) i believe.

    I chose customize, but there are two options. There’s the Darwin x86 bootloader and an option for Darwin EFI.

    I didn’t choose a bootloader for the first time, and I am probably not going to patch it (As it comes pre-patched). However, i’m going to now try the boot-fix as mentioned above.

    I previously installed leopardx86 w/ and w/o the bootloader (i chose Darwinx86). Both times, when I booted from my external HD, it just showed a black screen with a flashing white line @ the top left.

    Any help would be appreciated.

    24
  25. 25 nikRbokR

    I was not sure how to get it to boot w/ the DVD as well.

    Also, when I did -s, i read several messages that the HD was “read-only”… is that a problem?

    25
  26. 26 Jaymus

    I tried the fix boot suggestion after installing without patching. I was able to boot leopard and it seemed quite functional except that my networking hardware wasn’t functional.

    I then installed the patches. Leopard would no longer boot. I repeated the fix boot instructions with no luck.

    It stops at the boot prompt, if I get it to manually boot it reports “HFS+ Error”.

    Please help!

    26
  27. 27 Bob

    nikRbokR

    To boot from the iATkos DVD, press F12 on start up. as for bootloader, the selection is explained pretty well. iATkos is already patched no need to re/post patch. If you select the appropriate bootloader should boot right after installation. Other wise see the above section for manual bootloader install. Good luck

    27
  28. 28 nikRbokR

    Bob

    I was not sure which bootloader to install. I installed Darwinx86… but I assume it didn’t work. I will try with EFI (?) this weekend.

    Thank you.

    I have a… Don’t know if this is a stupid question or not. What if… I get the Leopard CD or DVD that come with the Mac, and install it on a PC without any other OS on it, will this work??? do I need also go to install all this weird patches and stuff???

    Please let me know. Thanks

    Hi, I have an iMac with Leopard 10.5.1, original DVD and another original DVD 10.5.1. Can I use these original DVDs to make patched DVDs to install it on my Intel-PC!? How can I make this? Do I still have to download these files in the description above!? Please help me, many thanks!

    30
  31. 31 Bob

    McMichel

    The only patch ( pre and post ) available is by Brazilmac and it is meant for the 10.5 only. I very much doubt you can use it for the 10.5.1. Just use the iATKOS or Kalyway 10.5.1 and avoid all the headache. You can google all info you need. No need to re invent wheel here unless you have a better wheel in mind ;>

    I am not able to find my HDD in Tiger installation, I booted from TIGER DVD but not able to find my HDD over there in disk utility menu.
    I tried it on DELL VOSTRO laptop having SATA HDD.
    Can anybody tell me what to do…….

  33. 33 Jaymus

    What chipset does your motherboard have?

    I had that problem, though who knows if it was caused by the same things. Nevertheless, my solution at least in part involved chaning bios settings. I had issues in particular that were a result of my USB settings.

    33
  34. 34 vipin

    HEY jaymus

    What were the setting u made the bios.
    can u explain it a little bit, because I tried to configure my SATA drive as ATA and AHCI both but nothing is working

    34
  35. 35 jaymus

    I found disabling legacy USB support made the difference between USB hard drives working and not on an installed system. And it made the difference between the installer usually dying out with a weird USB resource lock error message before even giving the initial installation menu and working as expected.

    Unlikely: it’s possible that you could also disable old stuff like parallel and serial ports - doing so can free up interrupts, though that hasn’t seem to mattered since like ‘98.

    Lemme know how it goes.

    Cheers

    I am not following you. If you have upgraded your HDD from IDE to SATA you will have to use an appropriate driver in xp. If so then shouldn’t have any problem with OS X 86 installation if you follow the driver choice in the pre installation choices. Try the latest iATKOS_4.

    Good luck VJ. You may want to check your BIOS settings and try changing some things that seem like they could be related. On my machine I run osx86 on, I found disabling “Legacy USB Support” really helped with a lot of things. I installed my OSX86 setup on an IDE drive, but later used Disk Util (from the installation disc) to copy what I had on IDE over to a SATA drive and that worked too. But of course, it only worked because I had good drivers thankfully.

    if you are getting into OS X86 on your pc, then the driver supporting SATA is already loaded. Enjoy your mac on pc. If OS X “die from update 10.5.5″ then you might need to do EFI patching.

    By the way 10.5.5 upgrade ( !?!) is not officially supported by OS X 86 as I know. Only up to 10.5.4.
