Hackintosh upgrade from 10.7 to 10.8

There are plenty of excellent reviews of Mac OS 10.8 Mountain Lion, so this post will focus on the steps taken to upgrade my fully working 10.7.4 system to 10.8. This is not intended as a complete install-from-nothing guide, requiring a working 10.7.x system to start with.

First some details on the hardware used. My Gigabyte P35-DS3R/Q6600 system was re-purposed at the start of 2012, and replaced with the following:

• Gigabyte Z68XP-UD3 Motherboard
• Intel Core i5 2500k cpu
• 16Gb DDR3 Ram
• Nvidia 9800GT 1Gb video card from previous system
• 2Tb and 1.5Tb hard drives from previous system
•  DVD-RW  and BD-Rom from previous system

Hack Mini ITX 10.7 Server

In July 2009 I built a small Intel Atom based file server that ran Mac OS 10.5 Leopard. It served as a NAS box and later ran 10.6 Snow Leopard with the Plex media server feeding my HTPC and a WDTV box through network shares. While there was enough processor power available for these simple tasks, new developments were beyond the limited power the Atom offers. The Plex Media Server can now stream and transcode to iOS clients, if your CPU is up to the task. Lion Server is available as a $50/£35 add-on for the Lion operating system, adding all the server functionality you could want. iTunes will act as a music server for all the computers in the house. With so many possibilities available, it was clearly time for an upgrade.
