3. Patch DSDT files

You will find the complete guide here. there is also a great video tutorial but I'm only noting the main steps here below.

1. Reboot your Hackintosh and go to Clover menu.
2. Press F4 key. Nothing will be shown at this point but this will extract original ACPI files so we can patch them. you'll find them in EFI/Clover/ACPI/origin.
3. copy the origin folder to the desktop and rename it to patched. A backup is recommended.
4. Delete duplicate SSDT files if there are. they have same sizes and you can determine them by bash command ls -l SSDT*.aml.
5. Download iasl to disassemble .aml files to .dsl files. copy the downloaded file to /usr/bin to have ease access in terminal:

  cd ~/Downloads
  unzip iasl.zip
  sudo cp iasl /usr/bin

1. Download the file refs.txt present in this repo and place it to the patched directory.
2. To do so, run this command : iasl -da -dl -fe refs.txt DSDT.aml SSDT*.aml
3. Open MaciASL. go to preferences > sources > add :
   • name : RehabMan Laptop
   • url : http://raw.github.com/RehabMan/Laptop-DSDT-Patch/master
4. Go to your patched folder and open DSDT.dsl file. it shoud be opened with MaciASL.
5. click Patch icon in the top.
6. now we will apply each patch described below to the DSDT file. you need to select the patch name (the left tree bar) and click patch then compile, it should be compiled without any errors (warnings aren't importants).
   • RehabMan Laptop
     • [audio] audio layout 12
     • [bat] HP ProBook 4x0s G1
     • [igpu] Haswell HD4400/HD4600/HD5000
     • [sys] IRQ fix
     • [sys] SMBUS Fix
7. Once finishing go to File menu->save, then again File->save as-> DSDT.aml (file format: ACPI Machine Language Binary)
8. For SSDT files you need just to compile files without errors. (open dsl file, compile, save, save as .aml) and done.
9. now mount your EFI partition, and go to EFI->CLOVER->ACPI->patched and paste all the compiled .aml files.
10. close and reboot. everything should work now.

4. Getting Wi-Fi card working

1. I ordered this one after research and it works right out of the box.
2. After installation mount your EFI partition and open your config.plist with clover configurator and go to SMBIOS section and change it to MacBook Air 5,2. save and reboot. now It should work.
