LATEST UPDATE (March 7, 2014): DSDT Editor has largely been superseded by MaciASL, a faster and more convenient app for patching DSDTs. Check out our improved DSDT editing guide with MaciASL instead!
- DSDT Editor: Self-explanatory; this is a tool for editing DSDTs. You can make very advanced edits with DSDT Editor, but for this tutorial, we'll just be using the "Patch" function.
- A Hackintosh with Mac OS X Snow Leopard or Lion installed: DSDT Editor is a Mac app, so you have to install Mac OS X on your Hackintosh beforehand. If your Hackintosh isn't fully set up yet, you can boot Mac OS X with iBoot, Unibeast, or some other temporary solution for now.
- A patch for your Hackintosh's motherboard: A patch is a text file that contains the necessary DSDT edits for your motherboard. Patches are motherboard-specific; a patch for one motherboard model won't work with any other motherboards. You can download a patch for your specific motherboard from olarila.com (you need to register on olarila.com to view and download the patches).
In some ways, patching your own DSDT is more convenient than using a pre-edited DSDT from tonymacx86; unlike pre-edited DSDTs, patches will work with any BIOS version of your motherboard.
1. Open DSDT Editor, and go to File->'Extract DSDT' from the menu bar.
This will create an unedited copy of your motherboard's DSDT. If you get an error at this step, check /Extra in your main hard drive and make sure that there isn't already a file called "DSDT.aml" inside it. If so, delete that file, or move it somewhere else.
Once you've successfully extracted an unedited DSDT from your motherboard, go to the next step, where we edit the file by using a patch.
2. Go to Patch->Open from the menu bar. In the window that pops up, choose the patch that you downloaded from Olarila.
Another window (named "Patch") will pop up. Click "Apply" to apply the changes in the patch to your unedited DSDT.
3. Go to IASL->Compile. This will create a new DSDT that includes the edits in the patch, and it checks that file for errors. If everything went right, you should get 0 errors.
4. Go to IASL->'Save AML as'. A save window will pop up. Name your new DSDT as "DSDT.aml", and save the file in /Extra of your hard drive.
Once you've saved your DSDT to /Extra, you're done. Reboot, and your Hackintosh will now be running with a DSDT. Congratulations!
