Dell latitude 3490, i5-8250u: Catalina

Recommended Posts

Hello all, I post here the summary of my installation success (it was possible only with the help of Hervè and Jake Lo) on model Dell Latitude 3490. Maybe someone will need it (click on the title for full laptop specs).

 

 

Dell Latitude 3490  

 

71U-BWDdEGL._AC_SX569_.jpg.2afa7c1ed4c71c290fef788a2ef55dfa.jpg

CPU: Coffee Lake Intel Core i5-8250u quad core 8th gen

IGPU: Intel Graphics UHD 620

Ram: 8GB DDR4

SSD M2: 256GB

Bios: 1.5.0  1.10.0

Mac Os: Catalina 10.15.3 

 

 

Working:

 

  • full graphics acceleration on Intel UHD620 iGPU, including brightness control (Fn+s Brightness down Fn+b Brightness up) (with Lilu v1.4.2 + WEG v1.3.7)
  • multi-display with HDMI
  • multi-display with VGA
  • audio, including HDMI, (no microphone input) and headset output (with AppleALC v1.4.6 & layout 56 + CodecCommander v2.7.1)
  • GigEthernet LAN connection (with RealtekRTL8111 2.2.2 kext)
  • wireless and bluetooth with any compatible card (a DW1820A tested by Hervè)
  • left and right USB ports, including USB Type-C
  • integrated webcam
  • sleep & wake
  • battery management (with ACPIBatteryManager v1.90.1)
  • keyboard (with VoodooPS2Controller v2.1.2)
  • touchpad (with VoodooI2C v2.1.4 + VoodooI2CHID v1.0 + Voodool2CELAN v1.0), including tap-to-click (mandatory in PrefPane settings), scroll & zoom, rotate or other multi-finger gestures. Sometimes the cursor moves unexpectedly during use (jumping) but with VoodoolCELAN this is better.

 

Not working:

 

  • Fingerprint sensor
  • SD Card reader

 

 

For Bios settings follow this perfect guide by Hervè

 

For create bootable usb/Installation/Post Installation follow this perfect guide by Hervè

 

Is better to use the latest clover release,  for download it click here

 

 

You can also follow these steps, starting from the installation of the clover in the usb stick (after the media creation tool process in terminal is done) :

 

  1. Run Clover r5xxx.pkg and select USB (Install Mac Os Catalina) as destination
  2. Just flag in true on Clover for UEFI booting only, Install Clover in the ESP, UEFI Drivers - Racommended drivers - Install
  3. Open terminal and paste:
    diskutil list
  4. Choose your usb EFI partition and type (for example disk1s2):
    sudo diskutil mount disk1s2
  5. Open Finder and open mounted EFI
  6. Replace the EFI folder with this EFI.zip
  7. Boot from USB and install Mac OS

 

 

For post-installation repeat the same steps with these differences:

 

 

  1. Run Clover r5xxx.pkg and select your SSD/HHD as destination
  2. Just flag in true on Clover for UEFI booting only, Install Clover in the ESP, UEFI Drivers - Racommended drivers - Install
  3. Remove all usb sticks and others disk (leave only the target Mac Os disk) and just type :
    sudo diskutil mount EFI

     

  4. Open Finder and open mounted EFI
  5. Replace the EFI folder with this EFI.zip
  6. Go in EFI/Clover/Kext/Others and copy all kexts to /L/E
  7. Repair permissions and rebuild cache (first disable Gatekeeper and mount file system in read/write mode)
    sudo spctl --master-disable
    sudo mount -uw /
    sudo killall Finder
    sudo chown -v -R root:wheel /System/Library/Extensions
    sudo touch /System/Library/Extensions
    sudo chmod -v -R 755 /Library/Extensions
    sudo chown -v -R root:wheel /Library/Extensions
    sudo touch /Library/Extensions
    sudo kextcache -i /

     

  8. Done, reboot and Enjoy

 

 

Many thanks to Hervè and Jake Lo!!!

I updated today to 10.15.4 and works fine.

 

Only the VoodooPS2Controller.kext does not work. I replace with old VoodooPS2Controller.kext and work`s fine. 

headset output with AppleALC release (1.4.7) sometimes don't have sound.
