Chris.

I just completed setting up my Opti 755 this afternoon. I installed 10.7.4 using myHack and added some Kexts (NVEnabler64, VoodooHDA, IntelE1000e) to enable my video, sound and network and made a new serial with Champlist. The only thing giving me grief yet is that I still can't log into the Mac App Store I get the "An unknown error has occurred". Any ideas?

Haha!!! Got it!!! I started from scratch and recreated my USB Thumb Drive Installer using myHack and it worked as expected. Graphics/Network and Sleep are working after adding a few Kext files. Now I just have to get the App Store working... I am getting"An unknown error has occured."

Below in my SMBios.plist, any ideas as to how I can

Thanks for the suggestions but so far they aren't working... I updated my USB thumb drive with a different Chameleon release and now I get a different error...

Here is what I've done so far...
1) In Disk Utility on my Real Mac I formatted an 8GB Thumb drive into two Mac OS Extended (Journaled) with GUID partitions 6.5GB (For OSX Lion 10.7.4) and 1.5GB (For Supporting Tools)
2) From a purchased Lion 10.7.4 installer via the Mac App Store I mounted InstallESD.dmg from Applications/Install Mac OS X Lion.app/Contents/SharedSupport and ran "open /Volumes/Mac\ OS\ X\ Install\ ESD/BaseSystem.dmg" in Terminal.
3) In Disk Utility I selected the 6.5GB partition and chose the Restore Tab. I made "Mac OS X Base System" the Source and "OSX Lion" (the 6.5GB partition) the Destination.
4) After that was finished copying I renamed the partition back to OSX Lion as I prefer that name over "Mac OS X Base System" <-- I tested this without renaming and had the same results.
5) I opened the newly restored partition on the USB thumb drive and went to System/Installation and removed the Packages alias and replaced it with a folder called Packages.
6) In Terminal I typed "open /Volumes/Mac\ OS\ X\ Install\ ESD/Packages" and copied the contents to the new Packages folder I created on the USB Thumb drive
7) I then ran Extra Lion from this Tutorial (http://www.insanelym...howtopic=256729) and then ran Chameleon-2.1svn-r2059 which I had previously downloaded, making sure in both instances to select the USB Thumbdrive as the Destination for installing to.
8) Following that I plugged the USB Thumb drive into the Optiplex 755 MT and power it ON and press F12 to get the Boot Menu.
9) In the Boot Menu I select "USB Device"
10) I choose "hd(0,2) OSX Lion with no option (See attached) <-- this is my USB Thumb drive from above
11) I get the Error "can't find /mach_kernel" (See attached)

Any ideas as to why it can't find it? I've attached the Chameleon Installer Log and a screen cap of the Thumb drive contents incase those are helpful. The system installed and booted up fine under Chimera earlier so BIOS settings and hardware should be fine.

But that's just it, I don't think there is a DSDT file anywhere because I haven't installed ANYTHING on the hard drive yet... this is trying to run the OSX installer USB I created to install OSX 10.7.4 on the hard drive.

How? I haven't made a DSDT yet?
