About Bluetooth, it's kinda stupid that I some how pressed Fn+PrtSrc (which enable Airplain Airplane Mode). At first, I didn't realize that, because wifi still works on both macOS and Windows. Only when I tried to boot to Linux and couldn't enable wifi (it confused me for several days) that I realized that it's turned off at the hardware level. About VGA, alright I give up on it. For the info that VGA was treated as DP, I'm a little disappointed that I consider Dortania guide as a bible to Hackintosh :<

I don't think I'll give up on the VGA as noted here, VGAs on Skylake and newer are supposed to work.

FYI about VGA, yeah maybe I'll forget about that and use HDMI in case it need it. For Bluetooth, I've already followed the guide of OpenIntelWireless. The thing is, it worked when I first boot the hack up, but afterwards it didn't.

Hi, I've been researching these 2 problems for a while but seem stuck, so I'm here to ask for your help. VGA I followed Dortania Connector-type GPU patching. They note that VGA on Skylake is treated as DisplayPort so it should work. The weird thing is, connecting to an external monitor via VGA makes it go black (means there's a signal?), but nothing happens in IOReg: Under iGPU section, no framebuffers recognize that external monitor (except for the framebuffer@0 for internal display). On the other hand, connecting via HDMI works OOB (a framebuffer recognized it as connector-type of <00 08 00 00>, I don't recall exactly which port). Bluetooth I use the default Intel AC 8260 with IntelBluetoothFirmware port. The first time I boot the machine, it worked and I thought I'd made it. But another day, I tried to enable Bluetooth and it stuck at loading and couldn't be turned on. One more thing I don't understand why, is that even after I've reset and cleaned NVRAM, then tried other's completed EFIs, both of the problems persisted. I hope some of you might take a look. Thanks. My specs: CPU: Intel i7-6820HQ GPU: Intel HD 530 + AMD R7 M370 RAM: 8GB DDR4 2400 Ethernet: Intel I219 Wireless: Intel 8260 AC 1 x VGA Output 1 x HDMI Output 3 x USB 3.0 Ports (with 1 Port partially defected - it can charge phones, but no MTP signal) 1 x Combo jack 3.5mm PS2 Keyboard + ALPS Touchpad 1 x SD Card My EFI: https://github.com/xuanhung1509/dell-latitude-e5570-hackintosh Thanks.

After replace my EFI with yours, I got stuck at this screen. Also, it was little strange when booting up. Normally I would see the OEM logo one time (before selecting boot drive), but this time I see one other. I'm not sure if it has sth to do with the stuck. Oh and about USBMap, I may need to double check it (after my laptop boot up), cuz I remember assign some ports to internal already.

Hi guys. After a while messing around, I’ve got Catalina 10.15.7 installed on my notebook. Most of the things work, though there’re still some I need to fix, clean or optimize. 1. Adjusting brightness: I read Hervé’s post for patching DSDT to adjust brightness, but I don’t know where to put the patched DSDT into (Dortania says that I should not put DSDT.aml into ACPI). After a few researches, I got Fn + F11/F12 working for adjusting brightness. It worked after I insert a kext (BrightnessKeys) and a SSDT (SSDT-5378) into OC Folder. What is strange is that two elements came from different devices. The kext is from here, and the SSDT is from here. Without one of these two, it doesn’t work. Can I got a more optimized solution for this? 2. Sleep: Sleep seems to work if I click Apple Icon -> Sleep. However, if pressing Fn + Insert or closing the lid or pressing power button, sleep does not work properly. In particular, when pressing Fn + Insert, the screen goes black, but the led indicator stays static, and when I hit power up, the screen turns on immediately. On the other hand, closing the lid or pressing power button does not work at all. 3. Screen goes black after disconnecting with HDMI: When this happens, my system seems to become unresponsive. This morning, I tried to sleep (choose Sleep under Apple menu) before disconnecting. This time, the screen turned on, but somethings turned out to be broken: Bluetooth became unusable, and adjusting brightness using Fn + F11/F12 didn’t work anymore. After restarting, adjusting brightness worked, but bluetooth stayed the same (I guess the Bluetooth kexts broke) 4. Touchpad: Using standard VoodooPS2Controller kext works for me, but I see that there’s a kext that is made exclusively for ALPS on the forum (by Bronxteck) and I want to try that. However, after I installed that kext, touchpad does not work, it even does not recognize my touchpad as ALPS, and I've got to revert back to the standart kext. Could you suggest a workaround? 5. USB ports: These are all USB ports on my laptop, less than the limit (15). Should I need to disable XHCIPortLimit in config.plist? In addition to these, are there anythings else I need to optimize and clean up? My laptop specs: - Model: Dell Latitude E5570 - CPU: i7 6820HQ - GPU: HD 530 + AMD R7 370 (disable using SSDT-dGPU-off) - NICs: Intel Wireless AC 8260 + Ethernet I219-LM - Audio: Realtek ALC293 + Intel HDMI Audio - Hard Disk: Lite-On SSD M2 256GB This is my OC folder: E5570-OC.zip I hope you guys will take a look at it. Any help is appreciated. Thanks! Update: after proper USBMap, sleep and HDMI works well.
