dennisc Posted November 5, 2019 Share Posted November 5, 2019 Hi friends, after following Herve's guide and many others tips on the forum for this specific latitude7400, I have been implemented most of the functions,but 5 features can't work which may be caused by USB ports limited (Canno Point-LP USB 3.1 xHCI Controller). No Detecting(but Win10 works): Bluetooth(DW1560 pin-masking 5 pins, Lenovo version, it works better on another Hackintosh) WWAN Card (Huawei ME906C) IR Camera two USB 3.0 ports(only U disk works, but mouse can't) microSD Card Reader Working: I7-8665u with CPUFriend intel UHD Graphics 620 2048MB Audio ALC295 layout-id 77 WLan with DW1560 I2C Touchpad Screen Backlight control with Fn+F6/F7 Sleep and Wake Thunderbolt 3 USB 3.1 Controller(test U disk, mouse, charging) the clover and ioregistry files in attachment. EFI.7z ioregistry.7z Thanks! Dennis C 1 Link to comment Share on other sites More sharing options...
dennisc Posted November 8, 2019 Author Share Posted November 8, 2019 Solved! According to Hervé's post , I rebuild the config.plist again, and use the MacBookPro15,2 model(four thunderbolt) . Now, they can work: [done] Bluetooth(DW1560 pin-masking 5 pins, Lenovo version, it works better on another Hackintosh) [done] WWAN Card (Huawei ME906C) [done] Integrated_Webcam_HD (IR Camera also unsupported) [done] two USB 3.0 ports(only U disk works, but mouse can't) microSD Card Reader unsupported. PS: Audio ALC295 layout-id has change to 13. the `config.plist` file in attachment. config.plist.zip Link to comment Share on other sites More sharing options...
chenboxing Posted November 9, 2019 Share Posted November 9, 2019 Thanks for your EFI. It can work at my dell latitude 7400 as your description. But I found a problem with my outer 4K monitor. When I connect a 4k monitor to the HDMI port on my laptop I can only select 1080p/60. I've used RESx and can force 1440p but still not 4k 24/30hz (HDMI port is only 1.4). In windows it will do 4k 24/30hz. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted November 10, 2019 Moderators Share Posted November 10, 2019 Try this script https://github.com/xzhih/one-key-hidpi By the way, why did you pin-masking DW1560, does it not work without it? Link to comment Share on other sites More sharing options...
chenboxing Posted November 10, 2019 Share Posted November 10, 2019 @Jake Lo I used apple native bcm9436cs2 card with converted case in my latitude 7400, don't need extra kext driver . I set empty to the boot args. I had tried one-key-hidpi script before, also failed. I looked up large articles to solve the 4K monitor problems, seems this issue related framebuffer dvmt.

Moderators Jake Lo Posted November 10, 2019 Moderators Share Posted November 10, 2019 sorry, got confused with @dennisc specs Yeah, I also read some where you need to increase the DVMT to 128mb. Follow my guide here to do just that Link to comment Share on other sites More sharing options...
