- Download ML from Mac App Store (need a working Mac or Hackintosh to do this and an account on Mac App Store... and $20)
- Use Unibeast to make USB key (be sure to select Laptop Support)
- Copy tegezee's ProBook installer to the USB key... you will need it later
- Boot from the USB key, select to boot from the USB key from the Chimera boot selection screen
- Use Disk Utility to format your HDD with at least 1x Mac OS X Journaled partition. Partition scheme must be GUID (GPT)
- Proceed to install Mountain Lion to your fresh partition
- When it finishes and it comes time to reboot, boot once again from the USB key
- Select your newly installed partition on the HDD from the Chimera boot screen
- Complete the installation, creating your account, etc.
- When you're finished with that, you'll be sitting at the Mountain Lion desktop
- Now run the ProBook installer from the USB key (some people copy it to the desktop and run it from there)
Once you run the installer it is pretty self explanatory, but that doesn't mean that people haven't made mistakes first time in.
Basically you need to know:
- Your BIOS version
- Your CPU
- Your screen type (will be standard unless you have physically replaced the screen)
Then you basically walk through each option, expanding each of the options in the installer, to see what you need to select.
- For "OS X Version" you will want " OS X Mountain Lion 10.8
- Select "Chimera 1.11.0", assuming you intend to use it as your boot loader (recommended)
- Select "Ethernet Kext Installer"
- DO NOT "Bluetooth..." it is for Lion/SL versions of OS X only
- Select "AHCI patch" as you will likely need it (most HP ProBooks need this, some don't, but if you want easy way... just select it)
- Select "EDID generator" (recommended, but not required)
- If you have SSD, select "Sleep Fix Image Fix" (recommended, but not required... also if you have sleep issues you can try this as a solution later)
- Expand the "CPU SSDTs..." and select ONE SSDT appropriate for your CPU that is installed.
- Expand either "DSDTs for standard screens" or "DSDTs for 1080p screens" depending on whether you have the original screen or a custom installed screen
- Select ONE DSDT appropriate for your hardware, and BIOS version
- Select ONE "System Definition" appropriate for your laptop (8,2 makes the most sense for ProBook 15")
- The rest of the options as far as Tools, Color Profiles, and Screen Brightness Fix are optional (I think screen brightness fix is not necessary on ML)
At that point, complete the installation to your ML partition, cross your fingers, reboot, and see what you have...
