  1. @tommyluco So could you finally get your uhd 620 to work with acceleration on bigsur?
  2. Thanx for your reply! Yes I know, I just disabled these settings with the #, so I can boot again! Meanwhile I disabled the ACPI patches you've marked and disabled XHCIPortLimit because I've read, I don't need it since Big Sur 11.3 anymore...

  3. Dear members. Is there anybody out there, who got a Latitude 7400 2-in-1 to work properly with full GPU acceleration on Big Sur? As far I tried all kinds of settings, EFIs as well as I tried to generate my own from sample on. No luck. I got the Installer running with an Olarila image and could install Big sur 11.4. Somehow I found a EFI, which allows my trackpad, touchscreen, audio even the Intel WIFI card to work quite properly - as far tested. I tried different SMBIOS with different framebuffers, device-ids on and on. I updated and modified my BIOS (1.11.0) to unlock my CSR with: setup_var 0x6ED 0x00 and set PreAllocated and total allocated settings with: setup_var 0xA10 0x2 setup_var 0xA11 0x2 Actually I can work on my Laptop but I have no acceleration - only 7MB and my HDMI is not working - not built-in hdmi and not a usb-c -> hdmi dongle (but LAN over this dongle works though). That sucks, cause I need my monitor for work - my eyes are not the best!! My spec are: DELL Latitude 7400 2-in-1 (5WRVH) with 16GB RAM, Whiskey Lake i7-8665U with UHD 620 GPU and Full HD display My only modification is a Samsung MZ-V7E1T0BW 970 EVO 1 TB NVMe M.2 instead of the original NVMe shipped with the laptop. I've spent allredy over 4 weeks trying and trying.... I attach my EFI folder and ask anybody who can give me a hint or send me his EFI plz!!!! Also can give a reward somehow for your spent time!
