Takiller Posted July 29, 2020 Share Posted July 29, 2020 All is working, when I say all I mean everything. I am ready to assist anyone with the same model laptop and I will also try to help even if you've got a different one Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 29, 2020 Administrators Share Posted July 29, 2020 Why don't you write a guide describing the procedure you followed instead? And share a copy of the OC EFI folder you used along the way? Link to comment Share on other sites More sharing options...
Lego Posted July 29, 2020 Share Posted July 29, 2020 @Takiller, I also have a dell E6540 and I am looking to install BS on mine. Would you perhaps posting your OC folder so I can give it a test on my laptop? Link to comment Share on other sites More sharing options...
Takiller Posted July 29, 2020 Author Share Posted July 29, 2020 With pleasure and I wish you all the best. Please let me know once done with the installation and I will guide you further with the polishing touches EFI-11.1.zip Link to comment Share on other sites More sharing options...

Takiller Posted July 29, 2020 Author Share Posted July 29, 2020 @Hervé, Please don't get me wrong, as I get your point and I would love to do that. The thing is that it took me more than four weeks to get where I am today and chances are that I don't remember all the things I did. Anyway let me try: 1. Create a Big Sur USB installer 2. Download the EFI-11.1.zip on post 4 above and paste it in the EFI of the Big Sur USB installer 3. For the installation phase a USB Keyboard & Mouse are required 4. After the first login install VoodooPS2Controller.kext in Library/Extensions 5. Repair permissions using Terminal or Hackintool, disconnect USB Keyboard & Mouse and reboot 6. Your Keyboard & Trackpad should now be working, just fine tune it in System Preferences under Trackpad 7. Now is the fun part of getting Read/Write Access, which there are guides on Google on how to do that 8. After done with point 7, the snapshots will be deleted and "sudo mount -uw /" working go to 9 9. Please don't deactivate the Radeon HD 8790M if you require HDMI Audio and also set to false FakePCIID_HDMI in Opencore 10. Go to System/Library/Extensions/AMD8000Controller.kext, info.plist and add 0x66061002 in both fields where the other devices are 11. Step 10 is to make your sleep/wake to be 100% 12. Always remember that after making any changes in System/Library/Extensions/ you must always "sudo kmutil install --update-all" then "sudo kcditto" Link to comment Share on other sites More sharing options...
Takiller Posted July 29, 2020 Author Share Posted July 29, 2020 @Lego, You're are always welcome. Please get started and remember to have a USB keyboard & mouse handy for the installation. Opencore did not allow my VoodooPS2Controller.kext, so we will be installing that in Library/Extensions after the installation Link to comment Share on other sites More sharing options...
Lego Posted July 29, 2020 Share Posted July 29, 2020 Thank you very much as I was able to get it to boot on my M6700 and my E6540 which are completely different laptops but I have been trying for days without luck but now with your OC folder, I able to boot it on both!!! THANK YOU!!! I usually never install to /L/E, I just put it in kexts but I guess I will need to put in /L/E now. Thank you for all of the hard work, very much appreciated!! 1 Link to comment Share on other sites More sharing options...
