Sharing my experience with OS X on

HP DC7700

Firstly, remember you should replace the integrated Intel card with another one via PCIe.

 

 

What it contains?

 

Kexts

AppleACPIPS2Nub.kext - PS/2 Kext

 

ApplePS2Controller.kext - PS/2 Kext

 

fakesmc.kext - FakeSMC kext (which emulates SMC device) edited to works better on Core 2 Processors

 

Intel82566MM.kext - Intel 825xx Ethernet Kext

 

Other files

org.chameleon.Boot.plist -

 

SMBios.plist - Use it at installation only. After that you can use what you want

 

SSDT.aml - SSDT which generates C & P States successfully

 

DSDT.aml - DSDT fixed and patched by me

 

Patch list:

  • DTGP
  • HDEF (experimental)
  • EHCI (don't need to delete AppleHPET.kext)
  • ICH8 LPC (to fix some errors with AppleLPC)
  • IRQs (to fix restart)
  • SHUTDOWN (to fix shutdown)
  • SATA (don't need to change device id in AppleIntelPIIXATA.kext)
  • SMBUS (recognized as ICH10 to fix errors with AppleSMBusPCI)
  • RTC (to fix errors with AppleRTC)
  • PBTN: _HID changed to _CID to get sleep working by pressing the power button
  • Some cosmetic patches

Known issues/problems:

  • Integrated card does not work
  • I haven't tried AppleHDA
  • SATA is a bit buggy because the motherboard doesn't support AHCI mode. For example, you cannot eject the Disc Reader by clicking on the icon (on the menubar)
  • Sleep doesn't tried. (i have integrated card only, sorry)

 

Pre-Installation / Installation

  1. Create the USB with OS X 10.7/10.8 installer.
  2. Copy DSDT.aml, SSDT.aml, org.chameleon.Boot.plist and SMBios.plist to USB/Extra.
  3. Install fakesmc.kext in the USB Drive.
  4. If you have PS/2 Mouse/Keyboard, install also AppleACPIPS2Nub.kext and ApplePS2Controller.kext.
  5. Turn on the PC, and boot into the usb.
  6. Press 'Enter' to your USB Drive.
  7. Install OS X on your drive.

 

SemiPost-Installation

  1. Return to the OS X USB installer and click Utility -> Terminal.
  2. Now, execute this commands:
    cp -R /Volumes/(USB)/Extra /Volumes/(Mac OS X Drive)/Extra
    cp -R /Volumes/(USB)/System/Library/Extensions/fakesmc.kext /Volumes/(USB)/Extra /Volumes/(Mac OS X Drive)/System/Library/Extensions/fakesmc.kext	
    - OPTIONAL for PS/2 USERS -
    cp -R /Volumes/(USB)/System/Library/Extensions/AppleACPIPS2Nub.kext /Volumes/(USB)/Extra /Volumes/(Mac OS X Drive)/System/Library/Extensions/AppleACPIPS2Nub.kext
    cp -R /Volumes/(USB)/System/Library/Extensions/ApplePS2Controller.kext /Volumes/(USB)/Extra /Volumes/(Mac OS X Drive)/System/Library/Extensions/ApplePS2Controller.kext
    


 

Post-Installation

  1. Reboot with the USB Drive, but now press 'Enter' to your installed drive.
  2. Now install Intel82566MM.kext to your drive to get Ethernet card working.
  3. AUDIO: This is the AppleHDA.kext patched for this PC. I tried this kext but i cannot get the sound card working. (I added the HDEF Device, don't worry about that). If you cannot use AppleHDA.kext, use instead VoodooHDA.kext (should work good).
  4. Reboot, and you should get all working.

 

Note: i haven't this PC anymore, that was of a my friend. That was my experience about this pc.

Confirmed with 10.8.3, I did some more HDEF DSDT edits and cannot get sound to work, tried VoodooHDA and it works but the sound is very low.

 

I have a $2 USB sound card that works OOB so i am using that.

 

Only extensions in /Extra FakeSMC.kext, Intel8266MM.kext and Sleepenabler.kext

 

Other then built in sound everything works, GeekBench score is 3400, not a fast machine but good for general purpose web, word documents and social media stuff.

Sound does work under Mountain Lion with the procedure & files here:

 

http://www.osx86.net..._hp_dc7700.html

 

I did not need or use the HDAEnabler.kext, but I did patch the HDEF section of the DSDT as shown. Unfortunately, I could not get it to work under Lion, but VoodooHDA v 0.2.1 seems to work just fine.

 

I used the install method in this guide:

      Hello,
       
      Few days back I had bought HP Elite Desk 800 g1 workstation and its config. is:
       
      Intel Q87 Chipset motherboard
      Intel core i5 4570s processor
      4gb DDR3 ram
      500gb hdd
      4gb GTX 1050 TI OC LP
       
      In this machine I successfully installed macOS Sierra 10.12.6 (16G29). But I'm getting an error in verbose mode like some contagious file. Also I'm getting an error of shutdown. I have attached the screenshot of the same. I have also recorded the video and its url is : 
      You may see it at 0:40 seconds. Later on when whole process get completed then I get an error of shut down "You shut down  your computer because of a problem." Again and again I'm getting this error on every restart. If I'm somewhere wrong for any kext or any other thing for that, here is my EFI folder (https://drive.google.com/open?id=1k-MSKSHXK9TL3WOBPZj6O789jBau7kWx). Also I have attached my config.plist file. Audio is working, but didn't recognised the device. About this Mac is also showing details properly.
       
      Please help me out it would be grateful and appreciated
       
      Thanks

      Hi, i can someone help me with installing mac OS Mojave on my HP ENVY - 15-as102na?
      I have an imac to use for setting up my usb & installing MacOS Mojave.There are various kext files etc that i'm not sure about and need some help as some are hardware specific.
      I tried previously but got stuck on an apple logo and couldn't get past that, and tried today and had problems with Clover.
      Once i get mac os on my 128gb m.2 ssd ( which i'll upgrade to either a 256gb or 512gb depending on how well this hackintosh works)
      I have a free 2.5" inch hdd bay where i'd like to install windows on in the future.
      I think i may have to replace my wireless card ( based on a few google results) which i'm fine with as long as i can see it working without just so i know i won't waste money
      Specs:
      Cpu: i5 7200u
      GPU: HD 620
      8GB ram
      Wifi card- Intel Wireless 7265 ( Intel® 802.11ac (2x2) )
      Motherboard - HP 81D2 & BIOS version is f.56
