How to install Mac OS X on HP Pavilion dv7

This guide helps to install Mac OS X 10.6.4 on your HP Pavilion DV7 laptop. Please verify your laptop hardware before making any changes. This guide does not work for AMD processor and Intel graphics cards. Intel processor and nVidia graphics card are required.

As we have in our household several real Apple Mac computers, this installation is experimental only. I'm curious about Mac as OS on PC. Actually all Apple computers are now PC-s, so there isn't any big difference between PC and Apple computer. The biggest difference is the BIOS, as Mac OS X requires special BIOS.

So installation of Mac OS X on PC is just erasing the gap between your PC BIOS and Apple Mac OS X.

HP DV7 is powerful laptop, which is twice cheaper than same class MacBookPro. My HP DV7 model is one year old, so latest models are more powerful.

Step 1: Prepare Installation Media & Install

This is an important step. If yo fail here you never get a chance to see Mac OS X booting on your laptop. You have several options how to boot Mac OS X installation media.

  1. Boot from USB flash drive
  2. Boot from CD + DVD
  3. Boot from especially prepared hard disk

1. Boot from USB flash drive (no working solution yet)
I had serious issues booting installation media from USB disk. I got error "EHCI controller unable to take control from bios". This is common problem for certain laptops, when you are trying to boot Mac OS from USB flash drive, as it couldn't communicate with USB.

This option might work on your model, I couldn't use this option.

  1. Open Disk Utilities and recreate partitions on your flash drive. Use GUID partition table.
  2. Mount Mac installation media
  3. Use Carbon Copy Cloner to copy content of Mac installation DVD to your USB flash drive
  4. Install Chamelon on your flash drive (be careful, choose correct drive)
  5. Add additional kexts into E/E folder on your flash drive
  6. Use mKext utility to create extensions cache
  7. Boot your laptop from flash drive
I got error "EHCI controller unable to take control from bios". So I couldn't continue with installation. This solution might work on your model.

2. Boot from CD+DVD (if you don't have another Mac)
This solution is very helpful if you don't have any Mac available for making USB or hard disk installation.

You need USB keyboard and USB mouse, as built in keyboard and mouse doesn't work with this method at installation time.

Use MBCD to boot your laptop.

  1. Prepare a very big cup of coffee as installation might take a while.
  2. Burn MBCD to blank CD
  3. Boot your comp with MBCD
  4. Press F5
  5. Take MBCD out and put Mac Installation DVD into drive
  6. Press F5
  7. Wait, you might get some errors, wait a bit until DVD appears on boot drives list
  8. Select Mac Installation DVD and press Enter
  9. Wait until language options appears and choose your language, press arrow button
  10. Open from menu under Tools section Disk Utilities
  11. Create GUID partition on your hard disk and name it
  12. Close Disk Utility
  13. Choose install options, remove language which you don't want and choose another options
  14. Close options dialog
  15. Choose your new partition as installation location, press Continue
  16. Wait until installation completes (you might got yellow error sign when installation completes, don't worry, its ok)
  17. Reboot you laptop again from MBCD
  18. You will see boot options, choose your new drive, choose it and choose verbose boot option and press Enter.
