How To Patch DSDT-SSDT For HP Haswell Laptop From Beginning To End

2015-09-11 New and complete steps to patch dsdt and ssdt.

Ok, I decided to write up a full tutorial about how I get my Yosemite 10.10 to work on my HP SleekBook Haswell i7-4550U HD5000: Sleep/wake/battery/sound/backlight slider/speedsteps/turbo/USB3.0. It’s a long video, but it starts from the beginning to end. It took me a long time to figure out how to get it done. I may not do it correctly, but my laptop is working very nicely and solidly.

If we patched and generate SSDT’s correctly with ssdtPRGen.sh, we should achieve the idle @ 800Mhz and maximum Turbo designed by the manufacturer.

  1. and also if can fix kexts for audio and I do not know it will fix by DSDT.aml my sond card is IDT High Definition Audio Device thanks.

      1. hello Sir and thanks for your quick replay.
        I tried installed voodooHDA 2.8.4 but it did not work this is the error massage that I get.
        ”System extension cannot be used
        the system extension ‘’/system/Libray/Extensions/VoodooHDA.kext’’ was installed improperly and cannot be used. Please try reinstalling it or contact the products vendor for an update”
        and i did it reinstall but did not work i tried all of version VoodooHDA but did not work accept one version VoodooHDA 2.7.3 it works but the volume control did not work and got kernel panic after restart if you have any Idea Sir? and thanks from your help.

      2. remove AppleHDA.kext to solve kernel panic – open voodooHDA.plist to set volume from false to true, then the volume will work

      3. hello again sir. and thank you from your quick reply i tried to voodooHDA.plist to set volume from false to true, it disabled sound card it look like you did not install kext or install wrong kext i tried to changed one by one and all of them to different ways but it did not work and thanks that kernel panic problem solved woth appleHDA.kext removed but the song volumes problem did not solve i want to ask something can i fix my own DSDT.aml self with MaciAsl I tried many times but i could not fix the compile errors. thanks.

      4. You need to use Kext Helper B7 to install VoodooHDA.kext for it to work. It’s the best kext installer. Email me your DSDT.aml, is it the original one from RWeverything? Where did you get this DSDT.aml?
