I believe Jake has mentioned everything that could be looked at: 1) make sure LAN is not disabled 2) try enabling and/or disabling Legacy ROM option

Then you have a problem with your BIOS settings...

Go to System Preferences then Network... If there's no Ethernet listed, click on + button at bottom left corner and select Ethernet as interface to add.

Erm... 0x03 = 0x3 !

It should make no difference whether PXE is enabled or not (it's used to boot OS from LAN) but I never keep PXE on. The Mausi kext is clearly loaded, therefore check your Network Preference Panel. If the Ethernet still isn't there, you should now be able to manually add it.

Then install it manually: copy the kext to /Library/Extensions repair permissions and rebuild your cache: sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo kextcache -Boot -U / If you obtain an error message "....77", repeat the touch + kextcache commands.

Apple removed the built-in facility to have a Display icon on the Finder's bar (that's what the "menu line" is called) when Mountain Lion was introduced back in 2012. If you wish such a tool, you can refer to this old thread on the matter (I personally still recommend (and use) Display Menu app today)… Do think of using the forum Search facility. Re: HDMI audio, make sure to use: patched AppleHDA patched SNB framebuffer Everything is already available here.

You've not bothered to apply any of the changes suggested in post #7.

"I can not activate the the Monitor icon on home screen"... Sorry, I don't understand; what do you mean?

Seems Ok. You say you're booting off an external USB disk. Did you try to boot with the internal HDD removed?

Well, those offending kexts sure aren't in the cache or list of kexts to cache; otherwise, they would be listed in the warning about invalid signature. On that basis, we have to conclude that they are injected by Clover through the EFI/Clover/kexts/10.12 or EFI/Clover/kexts/Other folder. There can be no other explanation. 'might be a good idea to post a zipped copy of your full EFI folder...

From Terminal, type the following commands. 1) to remove prelinked kernel (it should auto re-generate): sudo rm -f /System/Library/PrelinkedKernels/prelinkedkernel 2) to remove kext cache: sudo rm -Rf /System/Library/Caches/com.apple.kext.caches/* 2) to rebuild cache + prelinked kernel: sudo touch -f /S*/L*/E* sudo touch -f /L*/E* sudo kextcache -Boot -U / (or: sudo kextcache -system-prelinked-kernel) If you get an error message "... 77", re-type the touch + kextcache commands. Ignore any message "... 17".

Then the offending kexts are still cached. Try and manually delete cache folders + prelinked kernel, then rebuild the cache.

If you've rebuilt your cache and there are still traces of the offending kexts, try and locate them on the disk. From Terminal, type: sudo find / -name NullCPUPowerManagement.kext -print 2>/dev/null and repeat this for the VoodooPS2Controller kext. One question: this EFI folder you're looking at, is at at the root of your Sierra partition or in the mounted EFI partition? Make sure to look in the right place...

@OliverZ: Apple has no native support for mobile Haswell iGPU; that's why all laptops based on mobile HD4200/HD4400/HD4600 iGPU must fake desktop HD4600 model (id 8086:0412). Of course, you could try MBP11,1 or MBP11,2 SMBIOS, but I had no graphics issue using MBA6,2 on my mobile HD4600-based E6440.

...and the AGPM settings you used would be?

When you fake desktop HD4600, I believe it's 0x80860412, not 0x04128086... Use latest CloverConfigurator and there'll be no doubts.

No, you also need to rebuild your cache, otherwise it's as if the kexts were still present. Open up Terminal and use the following commands once kexts have been deleted: sudo touch -f /L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / If you use Clover, make sure the kexts are not in the EFI/Clover/kexts/10.12 or Other folder.

Great! Would be useful for other users if you could provide the settings you used (Mac model, PCI ids, thresholds) and the various GPU core/Memory frequency steps you noticed... 162/???? MHz 202/1620 MHz 405/???? MHz 666/3010 MHz

Confirmed to work on Precision M4400 with nVidia FX 770M and Precision M4800 with nVidia K2100M.

Re: Bluetooth, disable the search in the BT PrefPane.

There is no support whatsoever for cards based on that Broadcom chip (e.g.: DW1530, DW1540). https://osxlatitude.com/index.php?/topic/2120-inventory-of-supported-and-unsupported-wireless-cards/ myHack v3.3.1 fully supports Mavericks installation but the buck stops there. The pack you've referred to comes off my myHack-based E6220 guide. If you've properly installed it at the onset on the myHack USB installer, myHack will install it automatically at the end of the Mavericks installation. It may not install the boot loader though, but that's easy to sort out: boot the finalised installation via the USB installer, then download and install a recent Chameleon (or Enoch) package.

Tried the double keypress to remove CAPS lock? That's necessary under Sierra.
