    Dell XPS 8500 with Mavericks

    Install the patched appleintelcpupowermanagement from multibeast or nullcpupowermanagement from multibeast(one or the other).

    You should re-install the patched AppleIntelCPUPowerManagement.kext and the AppleACPIPlatform rollback with multibeast to fix the issue. The upgrade causes these files to be replaced with vanilla versions.

    The important thing to note in this configuration (when I used to run it) is that when you boot the machine, you must always boot with the HDMI interface. Don't try to boot while the ATI card is attached to a monitor. It won't work. I had an HDMI switch that let me switch between my ATI card...

    Hi All, Regarding 10.8.2 Update: I screwed something up and ended up having to start from scratch with a new 10.8.2 Unibeast installer. That went well but I also needed to use the ACPI rollback mentioned earlier in this thread. I was changing a bunch of components (new vid card too) and...

    GeForce nightmare

    Try booting with GraphicsEnabler=no flag. Or, try PCIRootUID=1.

    It sounds like you're referring to the USB 3.0 ports on the XPS 8500. Those are the blue ports. They should work out of the box as Mountain Lion supports it. If they aren't working, I would check to make sure if USB 3.0 is working in Windows/Linux for you. I have read about problems with the...

    Hi JHM, 1) To alter the kext, first put a copy of it somewhere where you can work on it (and so you don't disrupt the original one). 2) Right click on the kext through Finder > choose the option to show the package. This should open up another finder window. 3) In the new window, open...

    JHM, I actually think HDMI audio is already working (video is already working with my instructions). I'll have to plug it into my tv to find out. This is all using the HD 4000 video output. For NVIDIA cards, I presume they all "just work" - but I'll have to get an Nvidia card to find out.

    Yeah - I have to get an Nvidia card as soon as I can. I purchased the Radeon 7770 from Dell using a gift I got with the 8500 purchase. I should have instead bought an Nvidia card. But, at that point, I wasn't sure if we could eventually run OS X on it. I was running into walls trying to get...

    Yup - speedstep is working if you see the jumping of frequencies. During idle moments, you should see the frequency/multiplier/voltage drop for power saving. When it needs more horsepower, it should jump up. I don't know why bluetooth isn't working for you. For me, it worked out of the...

    For SpeedStep, I use the chameleon bootloaders ability to generate P and C states automagically. To turn that on, add this to org.chamelon.boot.plist: <key>GenerateCStates</key> <string>Yes</string> <key>GeneratePStates</key> <string>Yes</string> Or, use a utility like "Chameleon...

    Hi, For audio, try this: 1) Install the latest VoodooHDA posted here: http://code.google.com/p/voodoohda/downloads/list 2) After the installer finishes, don't reboot. Install the VoodooHDA kext from the zip attachment i posted earlier. I use a utility called "Kext Wizard" to help...

    Hi Msoorachi, You definitely can't use graphicsenabler=yes with this system. Use the gfx string I posted in my first post in org.chameleon.Boot.plist. That will let give you full graphics. As for audio, I use VoodooHDA http://code.google.com/p/voodoohda/downloads/list. Download the...
