To enable the dual screen support on a multi-monitor Hackintosh equipped with an AMD Radeon HD 6870 under OS X Mountain Lion (this works with the current 10.8.4 too), enter the following shell code into your Terminal session:

sudo perl -pi -e 's|\x00\x04\x00\x00\x04\x03\x00\x00\x00\x01\x00\x00\x12\x04\x05\x01\x00\x04\x00\x00\x04\x03\x00\x00\x00\x01\x00\x00\x22\x05\x04\x02\x00\x08\x00\x00\x04\x02\x00\x00\x00\x01\x00\x00\x11\x02\x06\x04\x00\x02\x00\x00\x14\x02\x00\x00\x00\x01\x00\x00\x00\x00\x03\x05\x04\x00\x00\x00\x04\x02\x00\x00\x00\x01\x00\x00\x11\x02\x01\x03|\x00\x04\x00\x00\x04\x03\x00\x00\x00\x01\x00\x00\x12\x04\x04\x01\x00\x04\x00\x00\x04\x03\x00\x00\x00\x01\x00\x00\x22\x05\x05\x02\x00\x08\x00\x00\x04\x02\x00\x00\x00\x01\x00\x00\x11\x02\x06\x04\x00\x02\x00\x00\x14\x02\x00\x00\x00\x01\x00\x00\x00\x00\x03\x05\x04\x00\x00\x00\x04\x02\x00\x00\x00\x01\x00\x00\x11\x02\x01\x06|g' /System/Library/Extensions/ATI6000Controller.kext/Contents/MacOS/AMD6000Controller

This is a single line of a code, mind you. After the patch completes, rebuild the system cache using the following commands or any other method you prefer:

sudo touch /System/Library/Extensions
kextcache -system-caches

Reboot, and you’ll have dual screen support.

If you ever wanted to access your Photo Stream files directly on your Mac, this one is for you, the files are located in:

~/Library/Application Support/iLifeAssetManagement/assets/sub/

Just hit command – shift – G in Finder and paste the above path and click Go. You’ll see a list of directories with random hashes, each containing a single file synced from the iCloud. To remove the directories from the view, filter by type Image, and optionally create a Smart Folder.

802.11n 450mbps WiFi PCIe card with native Airport support on OS X

For Hackintosh builds you have several Wireless networking options.

You can either build your own one from an Apple mini PCIe boards and a mini-PCIe to PCIe adapter card, or buy a ready-made card that happens to be natively supported in OS X, plus has full AirPort support. The cheapest such card is the TP-Link TL-WDN4800 Wireless N 450Mbps PCI Express Adapter Amazon $44.99

 

While this card costs more compared to the mini PCIe adapter method (that sometimes requires device id tinkering with the cheapest 3rd party wifi boards), it requires no extra drivers and works out of box in both OS X 10.7 Lion and 10.8 Mountain Lion.
