If you hit Enter, will it continue to boot? Try updating the Clover version.

Place bootx64.efi in the directory /EFI/Boot/

See my E7450 Guide regarding the DVMT. Then follow my Clover guide, bootpack is on post #2 under Inspiron Broadwell 5558_HD5500_disable-nvidia.

The error is due to USB issue. Check you have AHCI enabled in BIOS again. Try leaving out the SSDT.aml

Looking at your Config.plist file, I see that your SMBIOS is blank other than declaring MBP9,2. I don't know if that's the cause, but try updating it with Clover Configurator.

What's wrong with Display preference? Can you post a screenshot?

Place them in /EFI/Clover/ACPI/Patched

Here, try this DSDT.aml.zip

Replace AppleHDA to /S/L/E with this one. I think the one Hervé (278.52) included is newer than 10.12.1 (278.23) Then run this sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / AppleHDA.kext.zip

you'll need DSDT patching. Boot to Clover, hit F4. Compress and attach /EFI/Clover/ACPI/Origin here. Use the More Reply Options on the lower right.

Add this to boot arg kext-dev-mode=1

Clover loader? Upload your boot files. Clover folder for Clover, Extra for Chameleon.

see post #4

You'll get that if you don't have NullCPUPowermanagement in /L/E. Confirm that you have copy AICPM from here. Download the correct version, and place it in /System/Library/Extensions and run sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U /

Looking at his boot pack, you need to copy the AppleHDA in /Extra/Copy_to_SLE overwriting the one in /System/Library/Extensions. Copy all the kexts in /Extra/Extensions to /Library/Extensions except NullCPUPowerManagement. Make sure to get the patched AICPM from the link he provided before rebooting. Change KernelBooter_kexts to No in kernel.plist Run from terminal sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / There's a IOGraphicsFamily.kext in /Extra/Extensions, I believe should be patched for the boot glitch.

If you had follow Hervé guide and bootpack for Sierra, everything should work, you just have to generate a different SSDT for your CPU. There's a link to his script in the same link. If you're curious about the binary patching, use Hexfiend to open /AppleHDA/Contents/MacOS/AppleHDA

Yes, you shouldn't be running 2 PS2 kext at the same time. If you have issue with Dr Hurts kext, you should post your issue there. Please read through his updates thoroughly before posting the same question he had answered. You should start with the last 4-5 pages regard version 7 and 8.

Replace Config file with this one. config.plist.zip

Use Clover. Follow El Capitan guide here, same process.

did you install AppleHDA_ALC255.kext to /Library/Extension as stated in post #2 above?

Should thank Dr. Hurt for his work. Kfiatos just modded it to his preference.

Yes, kext patching occurs on every boot hence hot patches. Booting should not be taken that long. Make sure to fix permission and rebuild cache. Also make sure you don't have verbose mode on. sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / To find you devices, launch DPCIManager.app, look in PCI List DW1510 can't be use on this model because it's fitted with an M.2 card. The slot is different. To get audio to work, make sure you follow the Clover guide. 7. Copy kexts from /EFI/Clover/Kexts/Other/LE to /Library/Extensions of Macintosh SSD Note: Ignore warning/error messages and click OK, then run commands below. 8. Repair permission and rebuild cache. Run command from terminal sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U /

I think the issue is with my patching. This should fix it hopefully. Replace 3 files in post #12 with attached Disguard! Not working, stick with origin files from post #12! Updated_patches.zip

what's your boot time? should be less than 6 sec Wifi? What device do you have on your system? If it's an Intel, it's not supported. Replace it with a DW1560 as I have on the guide.
