Mavericks Guide with myHack (Chameleon)

 

Specs:

Work in Progress!

1. Build USB Installer with myHack
2. Download and Extract bootpack Extra.zip
3. Relaunch myHack, select Install Extra, select USB Installer as target drive. Select "Use my Own" and browse to Extra above
4. Boot with USB Installer ( Make sure to plug monitor to displayport, use bottom DP if you only have 1 monitor) 
5. Format disk to GUID and Extended Journal and start the build 
6. When prompt, select "Use My Own" and point to Extra on USB Installer
7. Select Yes 3 times to delete issue kexts
8. Wait a few minutes, system will automatically reboot
9. Complete the install

 

Working:

• HD 4600 Full QE/CI
• USB 3.0 ( not tested for speed)
• Dual display is working with the 2 built-in DisplayPort 
• Sleep / Shutdown / Reboot with Dual monitor working using either DP monitors or active DP/DVI adapter ( thanks to ktbos' exhaustive testing)

WIP (Not working)

• Sleep works but on resume, black screen fixed - add -gux_defer_usb2 to org.chameleon.Boot.plist
• Sleep with Dual monitor connected with passive DVI to DP adapter
• Built-in Speaker / Headphone jack - loud pitch noise fixed thanks to ktbos - get boot pack under updates below

 

Note: Make sure to set SATA Operation to AHCI. For best result, set it to the Default, apply and then set SATA Operation to AHCI.

Make sure to remove external video card or disable it in the BIOS.
