@richw As far as I know, there's no audio check in Dell Diagnostic. You can try booting from an Ubuntu OS from an USB and test your internal speaker if you don't have Windows on it.

@scram69 The instruction is all inclusive but might not all apply to everyone. Since your system is a laptop, you don't need to follow step 8 for external keyboard/mouse, it's for Desktop system. Step 12 are for USB-C ports which only exists in newer system from probably Skylake or Kabylake and up, you could also skip that step for this system. Clover rename is basically for renaming EHCI / EHC2 to EH01/EH02 Launch your Config file with Clover Configurator, under ACPI, click on the List of Patches drop down, you'll be able to select those two patches. @galab You could share you file since you had already done all the work for this system. It won't change even if you use different SMBIOS, but you do need to change the definition to whatever SMBIOS you decides to use but the ports are the same.

@Nancy10 Make sure you set BIOS as this Set to Default, apply, then set SATA Operations to AHCI, set Boot List Option to UEFI, Disable Secure boot

Try this config Move AppleBacklightInjector.kext to /L/E, won't work in clover kexts/other repair permissions and rebuild cache For sleep to work, you'll need to disable the Nvidia graphics config-7559.plist.zip

@sadykovildar Sorry for late response. Try this for touchpad change _STA to XSTA in Device GPI0 Find: 5F535441 Replace: 58535441 TgtBridge: 47504930 change _CRS to XCRS in Device TPD1 Find: 5F435253 Replace: 58435253 TgtBridge: 54504431

@Nancy10 Try my Mojave guide here Use this bootpack, files goes into /EFI/Clover replacing the default installed by Clover Kexts in ../kext/Other/CopyToLE should be copied to /Library/Extensions after installation as part of post install. Good luck 7480_HD620.zip

Try set it to 0x3 anyway. See here

Remove AppleHDAIDT.kext from /L/E Remove IntelBacklight.kext from Clover/kexts/Other Remove OsxAptioFix2Drv-64.efi and EmuVariableUefi-64.efi from clover/drivers64UEFI Change Smbios to MBP8,2, for sandyBridge (HD3000). The MPB9,2, that's for IvyBridge (HD4000) is wrong. Repair permissions and rebuild cache

That's normal. You could turn off Bluetooth or disable Open Bluetooth setup assistance at startup if keyboard is detected

https://github.com/RehabMan/OS-X-BrcmPatchRAM Correct BrcmPatchRAM for Yosemite and below, BrcmPatchRAM2 for ElCapitan and up. That with BrcmFirmwareRepo.kext both goes into /S/L/E or /L/E Repair permissions and rebuild cache

Don't attach anything during install...ie. external monitor, e-dock...etc

See here https://osxlatitude.com/forums/topic/7346-applesdxc-driverdsdt-patch-for-o2-micro-sd-card-readers/?do=findComment&comment=87652

could be issue with your drivers. Remove these from drivers64UEFI OsxAptioFix3Drv-64.efi apfs.efi

Shows backlight level = 0% Try this, remove SSDT-PNLF.aml from Patched folder. Enable AddPNLF in Config.plist file

Get rid of NullCPUPowermanagement and GenericUSBXHCI in /S/L/E, then run this 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 / Look for the output of BrcmPatchRAM2 and BrcmFirmwareRepo.kext Rerun this until you see them in the output sudo touch -f /L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U /

try resetting nvram sudo nvram -c

Had you tried connecting to an external monitor to see if it boots to the login screen? Or try shining a flashlight to the LCD to see if you can see the login screen Lastly have you tried the Fn key to adjust the brightness? I think it's F5 and F6

You can try contacting the developer of VoodooI2C. I don't have any hardware with I2C touchpad so...you'll have to do some homework. https://voodooi2c.github.io/#Installation/System Requirements https://gitter.im/alexandred/VoodooI2C

If your 9020 is a Tower and not SFF, see here, just replace the USBPort injector in /EFI/Clover/kexts/Other https://osxlatitude.com/forums/topic/10979-installingupgrading-to-mojave-optiplex-9020-hd4600/?do=findComment&comment=87418

I don't see BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext in your kextcache_log file which means you don't have them in /Library/Extensions. Add those 2 kexts, repair permissions and rebuild cache. Reboot

I have the bootpack posted earlier in this thread, replace contents into /EFI/Clover https://osxlatitude.com/forums/topic/11259-dell-latitude-7490-mojave/?do=findComment&comment=87971

Try this config, made some changes from yours config.plist.zip
