septic Posted November 10, 2020 Author Share Posted November 10, 2020 i checked with a normal 27' monitor with dp-dp cable and it works. I will check again my 40' tv hdmi cable, i use it in combination with dock station and a hdmi to dp adapter and output is ok with windows. in 4k resolution. i will recheck the cables again. Btw, bluetooth works fine, thank you. You may add that also add in the list of "oob" : - Dock station 2013 ultraslim (my hdmi2dp adapter is a bit damaged, need to replace it soon, external screen works on 4k finally) - HD pro webcam c920 i am on latest Big Sur. One last problem i believe should be visible also to others, when I scroll the mouse wheel it goes a bit strange. In small mouse wheel scrolls, the mouse goes in a stable slow speed, independent of the mouse scroll speed settings, and only when i do quick mouse wheel scrolls only then the speed is getting faster or slower depending on the settings in mouse system preferences. Is there a way to fix the mouse scrolling a bit ? Link to comment Share on other sites More sharing options...

septic Posted November 11, 2020 Author Share Posted November 11, 2020 Bluetooth audio works fine, mic is not, tested that with samsung HS3000 and jabra75, had a meeting in the morning I had to switch back to usb camera mic, which works fine. Displayport audio works but you cannot control the volume. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 11, 2020 Moderators Share Posted November 11, 2020 External monitor audio is control from the monitor, not MacOS as are on real Mac computers. 1 Link to comment Share on other sites More sharing options...
septic Posted November 11, 2020 Author Share Posted November 11, 2020 DP audio, was more or less expected, what about bluetooth microphone ? Any idea if this is a driver or setting issue ? My mouse is a normal poor usb wireless logitech m210 I made Jabra75 work but without bluetooth, they have a usb adaptor (that i forgot that i had in the box) so i connected that and everything is ok now Link to comment Share on other sites More sharing options...
Appie070 Posted November 11, 2020 Share Posted November 11, 2020 Hello guys, I also have HP 840 G3 I installed Big Sur beta 11. I saw a video on youtube, the person used the same laptop. So I used his files and I did not change his files, because is same laptop. But now I can not get Intel Wifi and Bluetooth to work. I really do not understand the kexts files etcetera. Can somebody help me please? 1 Link to comment Share on other sites More sharing options...
septic Posted November 11, 2020 Author Share Posted November 11, 2020 You are lucky i just did it two days ago Which wifi card and bluetooth do you have ? I have the EFI ready for Intel wifi 8260ac and intel bluetooth and it works nice on current Big Sur beta version. I guess i can share my zip file.

Appie070 Posted November 11, 2020 Share Posted November 11, 2020 I have Intel wireless AC-8260. Can you send me the zip file? Link to comment Share on other sites More sharing options...
septic Posted November 11, 2020 Author Share Posted November 11, 2020 You can try that at your own risk. What i did is: took original zip from the guide I mentioned in post #1 removed brcmbluetoothinjector, brcmfirmwaredata and brcmpatchram3 kexts downloaded itlwm and interbluetoothfirmware and interbluetoothinjector kexts I kept my original config.plist file, i got a new one, checked youtube trainings how to use propertree. I did open propertree with the new folders, did "oc snapshot" to add the new folders in the config.plist, from this new plist i grabbed the intel lan and wifi new lines and added them in the original plist file, while in parallel removed the old <dicts> carefully with notepad++. So i have the original file with two new <dicts> and without the 3 brcm <dicts>. Let me find rar to split the file, there is a size limit of 20mb.
