cvanhoose Posted March 4, 2020 Share Posted March 4, 2020 Hello, first post. I am new to Hackintosh builds. I have an e5570 6600 i7 model. everything is working in Catalina minus wifi, 1820-non A model. Bluetooth works. I thought this model had the r7 370m but the hardware states 270m. Maybe I have the wrong bootpack installed. I am getting the black screen on the internal monitor when i plug in an external display via HDMI. What would be the cause of this behavior? This is the bootpack I used: Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 4, 2020 Moderators Share Posted March 4, 2020 DW1820 is not supported. R7 370m/270m not supported as Optimus is not supported in Hackintosh, so need to be disabled to save power via DSDT/SSDT patching Black internal screen when HDMI plugged in is a known issue. Workaround, place system to sleep and then wake prior to connecting any external monitor or close lid until external monitor switch to main, then open lid. LCD will become main and external monitor as extended. You can try playing around with EDID using Hackintool or any process you can find, no guarantee.

cvanhoose Posted March 5, 2020 Author Share Posted March 5, 2020 Thanks for the info Jake. With the computer booted and plugging in the HDMI, the internal monitor goes blank but the external works. I then hit sleep and both screens activate. Can replicate everytime even after rebooting several times. Thats good enough for me! I purchased the dw1560 and installed it today along with more ram. No wifi still, I will explore the site more for info, maybe a kext needs to be added. Chris Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 5, 2020 Moderators Share Posted March 5, 2020 kext should already be included: Lilu.kext & AirportBrcmFixup.kext Make sure it's enabled in the BIOS Link to comment Share on other sites More sharing options...
cvanhoose Posted March 5, 2020 Author Share Posted March 5, 2020 It is enabled in bios. Bluetooth is working, yet it was working on the 1820 also. Link to comment Share on other sites More sharing options...
cvanhoose Posted March 5, 2020 Author Share Posted March 5, 2020 I figured it out @Jake Lo! I went to the GitHub page for AirportBcrmFixup and it states: brcmfx-driver=0|1|2|3 enables only one kext for loading, 0 - AirPortBrcmNIC-MFG, 1 - AirPortBrcm4360, 2 - AirPortBrcmNIC, 3 - AirPortBrcm4331, also can be injected via DSDT or Properties → DeviceProperties in bootloader The Boot-arg was set to 1, I changed it to 2 and it works now. Whats odd is I have a 4360. 5Ghz wifi working at full speeds getting 850Mbps down. All components working great now, thanks for the help. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 5, 2020 Moderators Share Posted March 5, 2020 You must be using this bootpack YOu don't need that boot arg. Remove it and it'll still work. 1 Link to comment Share on other sites More sharing options...
