I recently went about the task of installing Mac OS X on my ThinkPad T43. I installed both Leopard and Tiger, so I will layout pretty simply how to install either on your T43. First of all the disclaimer: I will not be responsible for what may happen to your laptop, or the grey hairs you may get doing this. And you are only supposed to do this if you are an Apple developer and or have a license for the OS you are installing.
It is actually pretty cool to show off to your buddies that you are running OS X. My computer specs are the following:
IBM ThinkPad T43, Intel 915GM Graphics Chipset, AD1981B Sound Chipset, 2GB DDR2 RAM, and 60GB HDD.
Now onto the fun stuff. Firstly, the steps that are the same for Tiger and Leopard.
- You must use the paperclip trick to short out pins 6 and 12 on your VGA out. Just bend a paperclip into a U shape, with ends long enough to touch the contacts on both sides. Look at the following diagram to see which pins. Alternatively, you can take apart your laptop and solder the pins together from the inside like I did.
- Now you must back up all your data onto an external HDD, because we will be formatting the entire drive.
- Also, disable all CPU power management features in the BIOS because this slows the computer down quite a bit.
- We are done the initial setup stages.
- Download the install ISO from the green demon, or the pirate of the internet seas. Make sure you get the Kalyway 10.5.1 ISO and not any of the ToH ISOs. I repeat ToH WILL NOT WORK!
- Fire up the computer using the burnt DVD, and press enter when it asks you for startup options.
- Now, get a beer, and wait for this thing to boot up. If you get stuck on a blue screen with no cursor, that means that you did the paperclip mod wrong.
- Open up Disk Utility from the top menu, and create one partition (and name it whatever you want)
- When you get to the setup options screen, select SSE2 System, the MBR Bootloader, and also the Azalia Audio package.
- Wait for the computer to finish installing, and then restart your computer.
- Everything except the wireless and Quartz Extreme should be working now (No GMA900 leopard support yet).
- Go to http://code.google.com/p/iwidarwin/ and download the latest 10.5 Stable package.
- Run this in your terminal
sudo -s chmod -R 755 /System/Library/Extensions chown -R root:wheel /System/Library/Extensions rm -rf /System/Library/Extensions.mkext (if exists) rm -rf /System/Library/Extensions.kextcache (if exists)
- Reboot, and everything should be working at this point.
- Download the XxX 10.4.11 ISO from your favorite ’source’.
- Put DVD in, reboot, and press enter at the prompt to start the install.
- As same as Leopard, if it stalls at the blue screen without a cursor, it means that your did the paperclip trick wrong.
- Open up Disk Utilitiy from the top menu, and create one partition (and name it whatever you want)
- For the install, Select the NoEFI Package, the 8.9 SSE2 Kernel, and the GMA900 package, but NOT the fixer.
- Wait for the install to finish, then reboot.
- Once running, you will probably notice that not much is working, don’t worry we’ll fix that.
- Insert the Install DVD, and install the GMA900 Fixer and the AD198x package. You may have to dig in the install DVD to find the latter package. Once installed, reboot.
- You should not notice that you have working QE+CI, and also working sound.
- Now, download the Broadcom Ethernet Kext file, and extract it to wherever you can remember. You will need to copy this file over from another computer because ethernet/wireless isn’t working yet.
- Now, run the following commands.
sudo -s rm -rf /System/Library/Extensions/IONetworkingFamily.kext mv /PathToFile/IONetworkingFamily.kext /System/Library/Extensions chmod -R 755 /System/Library/Extensions chown -R root:wheel /System/Library/Extensions
- Now reboot, and you should have fully working ethernet, with the exception of your MAC address being 00:00:00:00:00:00. You can set your MAC Address by using the command:
ifconfig en0 ether <MAC Address>
- Go to http://code.google.com/p/iwidarwin/ and download the 10.4 Installer (Stable), and install the package. Reboot, and you should have working wireless (although you can only connect to unencrypted or WEP APs).
