    Downgrade From Mojave to High Sierra: High Sierra Installer

    Yes that'd be lovely if someone could share their experience: I never ever downgraded and wondered if the kexts that were added are also kept, just like in an Upgrade? that would, for example, disable itunes (which is a Mojave specific version I thought... might be wrong there) thanks to...

    [SUCCESS] Dell Precision T5500 - Quadro4000|Xeon X5680 (MacOS10.12.X)

    IMHO If you can't find mac drivers for the GPU It'll be a lot less hassle to switch it out to something supported... and yes, the network card is a pain. see my earlier posts. I gave up on that and got a usb to ethernet from aliexpress :-)

    This is a Dell Precision T5500 with dual 2,66 GHz 6-Core Intel Xeon at 64bit very happy with the results. should be easy to even upgrade to the slightly faster x5490 Xeons

    [SUCCESS] Dell Precision T5500 - Quadro4000|Xeon X5680 (MacOS10.12.X)

    the audio chip is this: ADI1984A and it works with this specific edited AppleHDA.kext, attached without the voodooHDA pref pane. I can even get 24 bit 192KHz output! that's a great DAC.

    [SUCCESS] Dell Precision T5500 - Quadro4000|Xeon X5680 (MacOS10.12.X)

    a little update: i figured out that having the BCM5754D.kext inside: /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/ makes it work! and I edited the plist like suggested in the first OP post from where you can also download the kext edit: ALTHOUGH... the strangest...

    dont do nvidia injection in the unibeast 8.0 installer maybe change your USB stick - I can't explain why but that seems to do the trick sometimes. nv_disable=1 and nvda_drv=0

    Hello! first of all, thank you for writing up your guide, It has been a haven during my struggle of making my T5500 behave well. QUESTION: do you have your video card in the PCI (upper) slot by any chance? It seems my T5500 will comply best with the PCIRootUID=1 .... although i'm...

    Inserting USB device cause Mavericks 10.9.1 to Freeze

    I think in this case the person also ended up reinstalling the multi beast boot loader or something, along with this realtek thing... Basically just rerun multi beast with different settings, especially the legacy usb stuff... try out specifically for your system! kind regards, HBJR

    Orange Icon problem

    There's one super-easy solution that i'd like to mention: for my Gigabyte Z77-ds3h it was just a matter of going into the bios, and selecting several ports as: HOT SWAPPABLE > ENABLE / DISABLED at this point, my mSATA (boot disk) is gray, and all the others are orange. if I want them grey, i...
