Please list your system specs CPU: GPU: Resolution: LAN: WiFi:

For different CPU, you need to change SSDT, not DSDT. You can just generate one with PikerAlpha's ssdtPRGen.sh included in my bootpack linked above.

This appears to be the same as DW1705 which is supported. Try patching the DSDT with the example by Hervé.

You could try my Clover guide here and use bootpack on post #2. Must set BIOS to UEFI

For Broadwell/Skylake system you need the Beta version of the script from here. Regarding audio, you can't just use the audio kexts without the DSDT/SSDT and Config file from my bootpack. It has all the patches and hot patches to get audio working along with other stuff.

Other kexts? What is not working? You only need kexts for devices that are not working OOB. Some can be fix with a simple DSDT patch, some will not be supported. If you only want Wireless, then go with DW1510. If you want both Wireless and Bluetooth combo, go with DW1550. See here with more selections If you do go with DW1510, be warned.

Does this model have the Nvidia graphics or Intel? If Intel, you won't have graphics support, system will run poorly. If Nvidia, you could follow the E6400 with Nvidia guide.

Just replace the entire Kexts folder, not merge.

Replace the Kexts folder with this. just the Kexts folder

You could start by listing the system spec For example: CPU :Intel Core i7-6820HQ Hard Drive: 512GB NVME SSD Graphics Card :AMD FirePro W5170M Screen: 17.3" UltraSharp UHD IGZO (3840x2160) Wireless Intel Dual-Band Wireless-AC 8260 Wireless Add-ons Bluetooth 4.2

Everything looks right at first, but a closer look I noticed that under GFX0@2, Compatible shows this pci8086,5916", "pciclass,030000", "GFX0"> It should be "pci8086,1916". I look through your DSDT and Config and not able to find anything that would have coded that in. Also, it might be a good idea to rename GFX0 to IGPU Update: Nevermind, that's the device ID for the HD 620

Attach your Config file

Remove from /S/L/E AppleIntelHDGraphics* That should be able to get you to install but without QE/CI

See here

Try this. If you have the patched file, you might have to restore the vanilla before this patched DSDT will work. DSDT.aml.zip

New bootpack allows USB 3.0

Clover Guide BIOS: Set to Load Default, apply, then set Boot List Option to UEFI, SATA Operations to AHCI, Enable Legacy Option ROMs Follow my Clover guide Use this bootpack (latest Bios vA20) Optiplex9020_A20.zip Bios vA22 Optiplex9020_HS_A22.zip (High Sierra ready but sleep is broken) Latest version Note: Use layout-id 17, Internal works, front /rear jack works, but need to manually select Use layout-id 16 if you want internal speaker sound, but rear audio doesn't work Use layout-id 15, both front and rear audio jacks work, but no internal speaker 9020_Catalina.zip Working: HD 4600 Full QE/CI DP Video / Audio Sleep / Wake USB 3.0 ( not tested for speed) Dual display is working with the 2 built-in DisplayPort Headphone / External Mic Not Working: Rear Headphone jack

Where did you get the source file? Sierra.app Maybe try another USB drive.

sudo touch -f /Volumes/driveName/L*/E* sudo touch -f /Volumes/driveName/S*/L*/E* sudo kextcache -Boot -U /Volumes/driveName

can you launch IOReg IORegistryExplorer_v2.1.zip and send me the file? without HDMI/DP video connected with HDMI/DP video connected Do you see if 10.12.3 have new FB for Kabylake HD620?

Can you boot to USB installer and then select the internal drive to boot?

Try installing FakePCIID, FakePCIID_Intel_HDMI_Audio, FakePCIID_Intel_HD_Graphics to /Library/Extensions.

In BIOS Try enabling CSM Secure boot -> disabled TPM -> disabled

Make sure you have EAPDFix installed for sound after sleep. There's no VGA on my system nor on Mac's, so I never tried it. 0 = Internal 5 = HDMI 6 = DisplayPort There's no port 7 on my system. HDMI can cause hanging or not respond sometimes when hot pluggin/unplugging. DisplayPort seems to be more reliable on my system. You can try experimenting, see Hervé's guide on Haswell HD4600/HD4400 for ideas.

The bootpack, make sure it goes in /EFI/EFI/Clover overwriting the default folders/files there when you install Clover
