Hitchi Posted September 21, 2020 Share Posted September 21, 2020 Hello everybody, have successfully installed Catalina on a VMware (Player)... everything works well. Update to Big Sur ... everything is running fine, either. I thought to myself "Hey, you still have a Dell 5490... Target system: Dell Latitude 5490 - Intel Dual-Band Wireless-AC 8265 Wi-Fi + BT 4.2 Wireless Driver - Intel Core i5-8350U processor - 8GB RAM - 14" FHD non touch display Have read and tried out various instructions (I'm a beginner but with IT knowledge). Long speech, short sense: I "stole" several EFI folders from different models (I didn't find 5490 matching) and tried to build something out of them. My issues: - Touchpad does work but no click (also left and right mouse button) does not work... ext. mouse works ...EDIT: FIXED! Just a simple configuration within trackpad options - WLAN does not work at all (Intel AC8265)... any way to get it running? - BT active but does not find devices so broken As I said, I've tried several EFI folders matching the CPU or similar Latitude model. End of the story was a no longer bootable macOS. So I've started all over again and before I write the EFI with issues mentioned above on the SSD I wan to solve them beforehand. W EDIT: Uploaded my EFI as a precaution. EFI_Hitchi.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 21, 2020 Moderators Share Posted September 21, 2020 You can try Hervé files from his 7490 guide. Intel wi-fi are still in development. See here. Otherwise replace it with a compatible device. Intel BT, try adding IntelBluetoothInjector.kext & IntelBluetoothFirmware.kext Link to comment Share on other sites More sharing options...
Hitchi Posted September 21, 2020 Author Share Posted September 21, 2020 Tried already but I had several issues with his EFI. Still to fix is WIFI and BT... For BT I'll try the kext you've mentioned For Wifi: Is there any guide for the open intel? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 21, 2020 Moderators Share Posted September 21, 2020 Just download the Intel kext and add to kexts/Other You'll need an app call Heliport.app to configure the settings. The native won't work. For Hervé file, just leave out the DSDT.aml, as it's specific to his system and BIOS version / Configuration. The only patch in that DSDT is to enable Fn+F11 and Fn+F12 for brightness. Without it, you'll you can still control with Fn+S and Fn+B. Link to comment Share on other sites More sharing options...
Hitchi Posted September 21, 2020 Author Share Posted September 21, 2020 OK, will try his EFI without the DSDT.aml BT is working after injecting the two files with Clover on the start USB boot stick only Wifi ... I'll search for a guide how to get the Intel AC8265 running Link to comment Share on other sites More sharing options...

Hitchi Posted September 21, 2020 Author Share Posted September 21, 2020 any suggestion how to speed-up the boot process/reduce boot time? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 21, 2020 Moderators Share Posted September 21, 2020 How slow is slow? Are you booting in verbose mode? Have you tried repairing permissions and rebuild cache? Link to comment Share on other sites More sharing options...
Hitchi Posted September 21, 2020 Author Share Posted September 21, 2020 every time I change something I use -v ...there are many retries of loading something... have to lookup something like a boot.log(?) OK repairing permissions and rebuild cache I've not tried. Done by terminal? I slightly remember some setting within one of the hackintosh tools or Link to comment Share on other sites More sharing options...
