Hi everyone, I successfully installed Big Sur beta 4 on my Latitude E 7450 using OpenCore 0.6.0. The machine is already running Catalina 10.15.6 based on Jake Lo's guide, so I will not repeat the same story (especially for specs). I only underline that this is the iGPU only model (no dGPU to be disabled here). Working: - keyboard, trackpad and trackstick (only with ApplePS2Controller provided in Jake Lo's packages. Latest VoodooPS2Controller will not be useful for this ALPS touchpad) - Wifi (thanks to Jake Lo patch) using a Dell DW1560 (as per signature) - Graphic card acceleration - Screen backlight - Bluetooth - Audio - SD card reader Not working - Bluetooth (and webcam) - Audio - Fingerprint sensor (of course, as always) - SD card reader Not tested - SD card reader (supposed not working) Hackintool (and IORegistry, of course) is able to recognize both audio and EH01 usb controller, but they seems to be "inactive" and I don't know how to fix them. Fortunately, USB3 is working, otherwise I couldn't install macOS since I used an external WD HD on a USB3 caddy. In any case, I share my EFI for development and further testing, especially for @Jake Lo. Credits: Jake Lo (and all the guys and teams who inspired him for his original clover guide) EDIT: Bluetooth, webcam and Audio work fixing IRQ issues by adding SSDT-HPET (and related patches) to ACPI. SSDT-PLUG is actually useless (you can even turn it off from the config.plist). I updated the EFI folder. EDIT 2: Properly injected device properties made the SD card reader working again. Thanks Jake! I uploaded the working EFI Updates: Big Sur Beta 5 (20A5354i) installed through software updates Big Sur Beta 6 (20A5364e) installed through software updates Big Sur Beta 7 (20A5374g) installed through software updates Enjoy!
