hshamsaldin Posted December 18, 2020 Share Posted December 18, 2020 (edited) Here is my OpenCore 0.6.4 EFI with modified ACPI-files and config.plist to work properly with HP EliteBook 840 G1. ## Changes: With Rehabman's SSDT-patches and kexts. You should boot OpenCore normally, but i have made very important changes to the ACPI-files and config.plist to make it as close to "Apple Like" as possible to fit the OpenCore mood. * Removed ~~SSDT-HDEF and SSDT-HDAU audio patches from SSDT-8x0G1h.aml~~, and Applies AppleALC audio injection, you'll need to do your own research on which codec your motherboard has and match it with AppleALC's layout. [AppleALC Supported Codecs](https://github.com/acidanthera/AppleALC/wiki/Supported-codecs). * Replaced ~~IGPU.aml~~ With PNLF.aml for backlight controls to work properly with OpenCore. * Removed ~~unnecessary config.plist patches that are made for other motherboards, like HP-840-G3~~. * Removed ~~SSDT-USB-8x0-G1 and USBInjectAll.kext~~. Reason for this is USBInjectAll.kext is no longer being maintained and the USBMap.kext version is how real macs USB map. [USBMap](https://dortania.github.io/OpenCore-Post-Install/usb/intel-mapping/intel.html). ## What Works: - **UEFI booting via OpenCore** - **Dual Boot with Windows/Linux** - **Built-in keyboard (with special function keys)** - **Built-in trackpad (Multi-Gestures)** - **Native WiFi & Bluetooth via Broadcom DW1560 BCM4352** - **HDMI Audio/Video with hot-plug** - **Native USB3 with AppleUSBXHCI using USBMap (USB2 works also)** - **Native audio, including headphone** - **Built-in mic** - **Built-in camera** - **Native power management** - **Battery status** - **Backlight controls with smooth transitions** - **Accelerated graphics Intel HD Graphics 4400** - **Wired Ethernet** - **App Store** - **iMessage & Facetime** Feel free to visit my GitHub repository for more detailed informations: https://github.com/hshamsaldin/OpenCore-HP-840-G1-Haswel EFI.zip Edited December 18, 2020 by hshamsaldin 1 1 Quote Link to comment Share on other sites More sharing options...

edtho Posted January 18, 2021 Share Posted January 18, 2021 Hi Thanks for the post, everything works except for one problem. The trackpad and the buttons in trackpad is not working. They where working during installation phase. After install they stopped working External USB mouse is working fine. Thanks again for the great efforts!

Col_W Posted January 25, 2021 Share Posted January 25, 2021 Hi, I have been trying to get this working on my HP 840 G1 with i7 and Intel/AMD graphics. I have a working Clover 5119/Mojave install and wanted to switch to Opencore to fix the update issues I get with OS patches. With your config I get to the boot menu but when I select my OS X partition it goes black for a second and then back to the menu. I can get the UEFI shell to open fine and I can also choose my Windows 10 partition which boots fine. I also get an issue if I try and update to a later version of Clover. I have tried reading through the Opencore guide but I haven't had enough time to learn it all yet. Can you think of anything obvious I should check?

Leon03 Posted January 31, 2021 Share Posted January 31, 2021 I will try the efi file in my 820g2 Quote Link to comment Share on other sites More sharing options...
Leon03 Posted February 8, 2021 Share Posted February 8, 2021 (edited) I modified my config.plist according to yours, and it can work in my 820G2. and I migrate to OC 0.6.6. It seems work well. I don't know how to test, such as multi-Gestures,backlight control... Change: 1. remove XOSI in SSDT-HACK.asl, and add SSDT-XOSI.aml & SSDT-EC.aml. Otherwise It can't boot into windows 10. (BlueScreen with ACPI_BIOS_ERROR) Problem: 1. I can't use USB keyboard & mouse in OC GUI. (But if I boot OC from USB disk, the usb keyboard can work) 2.when I boot into windows 10, the usb keyboard and mouse can't work. how to solve this?

Leon03 Posted February 14, 2021 Share Posted February 14, 2021 It seems that I make a mistake in my config. I didn't enable XOSI in config.plist. once I enable it, I still can't boot into Windows. Still try to slove this. Quote Link to comment Share on other sites More sharing options...

According to How to Identify the Windows Version in ACPI by Using _OSI, add Windows 10 version info in XOSI function. Quote Link to comment Share on other sites More sharing options...

I have exactly the same problem I can install Big Sur using hshamsaldin's EFI (with my own serial numbers etc) perfectly. The initial boot is fine and I can enter my AppleID and everything works perfectly. When I reboot I get the OpenCore menu with my MacOS install selectable, but when I chose this I just get a blank screen then back to the menu. It makes no difference if I boot from the USB installer or from the SSD (once the EFI folder has been transferred). Does anyone have any hints? If not I'll add the -v boot arg.
