This is the process I used to install iDeneb 10.5.5 with full NIC, Video, Sound support along with the update to 10.5.8! I want to say that the Dell Optiplex 755 is the most stable system for a Hackintosh! You will be VERY impressed at how well OS X runs on this machine! I’m George Zimmer Founder and CEO of The Mens Warehouse and I guarantee it!

Pre-installation:

BIOS settings: make sure that the mode for SATA controller as AHCI instead of ATA. In my case, original I set the bios as ATA, and I can successfully install iDeneb, however , after the reboot, I stuck at the gray apple logo, with a circle crossed. After several trials and errors, I set SATA controller as AHCI which is actually the default setting for dell bios A9.

iDeneb Installation Notes:
Do NOT select ANY of the Chipset, Kernel, Network etc. options from this. Just leave everything unselected!

NETWORK
1. Install “Intel82566MM” using Kext Helper b7.
2. Don’t reboot after installing.
3. “A new network interface has been detected.” prompt should appear.
4. Click “Network Preferences”
5. On the “Network” window make sure “Configure:” is “Using DHCP” then click “Apply”
6. Wait a few seconds and you should be connected with an ip address from your router.
7. Close the “Network” window.
8. Done!

Updating to 10.5.8
