Thanks a lot for your help Jake Lo, I did update my files with your last OC files and everything is working now!

Jake Lo, are you able to use the usb C port on the HP to connect to an external screen?

Here you are

`

For your info I basically use your last Big Sur OC folder and remove all the kext that were related to Broadcom as I use the Intel Wificard jones’s MacBook Pro.zip

 

edit: after checking my kernel logs via hackintool I see the following error appearing several times:

 

(USBInjectAll) <compose failure [UUID]>

(VoodooSMBus) <compose failure [UUID]>

<AppleACPIPlatform`AcpiOsVprintf> 2 table load failures, 13 successful

<AppleACPIPlatform`AcpiOsVprintf>  Namespace lookup failure, AE_ALREADY_EXISTS

<AppleACPIPlatform`AcpiOsVprintf>  Namespace lookup failure, AE_NOT_FOUND

 

Do you know what these messsages mean ? 

Hi Jake Lo,

 

I did update my HP 820 G3 to Big Sur using your last OC files for Big Sur only thing not working anymore is my audio. Can you please help me with this ?

 

it seems my IOReg file didn't loaded correctly to the post, here it is:

Check if your WIFI is not disabled physically. I mean via the shortcut key on the keyboard of your XPS...it happens to me

Thanks Jake Lo, it works!!! 

 

 

There is one last thing, this laptop has a 12.5" display, 1920 x1080 resolution is beautiful but everything is very small this display. Any trick to enable HIDPI on a scaled resolution? I tried 1600 x 900 but everything is blurred. Also tried a HIDPI script found on GitHub but it seems to take a lot of performance.

 

 

Jake Lo, my apologies, here is the correct fileioreg file.ioreg

ioreg file.ioreg

Jake Lo, here is my IOReg file.

 

Thanks in advance for all your help !

Hey Jake Lo i just acquired a 820 g3 model. I think it's very similar to your 840 G3 model as I used your OC folder and could directly install Catalina on it! This laptop is blazing fast with Catalina it really feels like a real MAC. I plan to use your OC folder as basis for my config but I would like to use my own patched SSDT's as think it will be even better performance of the overall system. Do you think you could help me with this?

Thanks JAke Lo! Regarding my backlight issue, do you have any idea what is causing this. My brightness level control and also automatic brightness level were perfectly functioning with your files on High Sierra.

 

One last question: this XPS have a touchscreen (L2C I think) is there any possibility to make it working like on my Lenovo Yoga ?

 

Thanks in advance for your help! 

Jake Lo, I did try to reset the NVRam but this doen't fixed the issue of the screen brightness.

 

Also I think that my trackpad is a Synaptics one, maybe I am using the wrong kext?

Jake Lo,  I lost my brightness control also the automatic backlight control. Do you know how to fix this?

 

Also when the laptop wake up, the trackpad loose the scrolling functionality.

 

Another question regarding my SMBIOS. With my kind of processor i7-410U shoul it be better to use another SMBIOS like one for MacBook Pro?

Jake Lo, I think there was an issue with my Catalina installation during the update. I did a complete recovery of OSX using the recovery assistant and could finally install Catalina on this laptop. Thanks again for your precious help!

The laptop restarted after update was done. I can get to the Opencore boot menu but after that I get a kernel panic than the white apple logo appears white a 3/4 full progress bar and keep hanging. Do you know how you can boot in verbose mode with OpenCore ?

 

Thanks in advance for your help

Jake Lo... you are a genius!! I could finally boot this laptop with Opencore!

 

I have launched the update to Catalina, I will keep you updated.

 

Thanks a lot for this!!!

Hello to all, I really need your help here.

 

Still several days that I am trying to boot this device using Opencore, I really think that there is something wrong in my config.plist

 

My OC folder is based on one of Jake Lo that I tried to adapt to my configuration but I think I am lost.$

 

 

Can someone please help me with this?

Hello Jake Lo, I finally choose to keep the XPS to high Sierra for now I a I have an external usb Audio adapter that is no more supported by Apple.

 

I really want to try to switch from clover to OpenCore but I am really lost here and asking for your help. Do you think it could be possible for you to create an OC folder for this laptop for me?  I tried to adapt your Dell 7440 OC folder to create mine but it doesn't work so I don't think this was a good idea..

 

Or maybe you can assist me in the creation of my own? May I use all the DSDT and SSDT used with clover in OpenCore?

 

Thanks in advance for your help

Jake Lo THANKS a lot for your time and your help!!!! your are just a fantastic person and a genius tech guy! Your knowledge is just facinating! 

One issue that I need to fix: when the laptop wake from sleep my keyboard isn’t responding anymore and seems hanging on a key... like my password login field is getting automatically filled to infinity... (it’s like I am pressing the “a” key non stop) and I can’t do anything but hard rebooting the device.

 

i don’t seems to encountering this issue it’s the other DSDT, but as this one isn’t originally coming from my own device, I definitely prefer use the one you patched for me.

 

any idea what can causing this?

Jake Lo I replaced the DSDT file with the one you patched for me...now Brightness control is working via the keyboard functions keys!!!

Thanks a lot for your expertise!!

 

Do you think Brightness automatic level is achievalble on this laptop like on my Dell XPS 12 ?

 

I have to say that this Lenovo Thinkpad is one of the more stable hack that I could use!! it's incredible!! Feels like a real MAC.

 

I updated this One from High Sierra to Mojave than Catalina without any issue. I really love OpenCore! It's crazy stable

 

Hey Jake Lo, first, thanks a lot for your reaction... I have to say that without your help and advises I couldn't got this result on this device.

 

The fact is that my OC folder originally one that I found on a German site in which I replace several files with yours given in the original post.

 

I thouhg that I was using your patched DSDT I willl first replaced my actual DSDT with yours!

 

 

I am near a perfect installation of Catalina on this laptop!

 

Sleep issue seems to be fixed for now.

 

What needs to be fixed is Automatic Brightness control and also Brightness control via the shortcut keys.

 

I know Opencore is not widely used but maybe can someone help me with this...

 

My question is: can I use the Debug tool from the forum with an OC configuration to provide you all the necessary debugging information needed like with a Clover installation.

 

Thnaks in advance for your help!

Just tried with the boot arg but without any success.

 

I will try to find a solution in order to capture a slow motion video from my verbose boot.

Jake Lo, after restarting it seems that I can't not boot anymore, it hangs at apple logo and doens't load to the desktop, I post a picture of my verbose screen. Any Idea how to fix this?

 

Jake Lo sorry for my late response! Your SSDT file fixed my Brightness issue and I am currently updating to Catalina!

 

Again, thanks a lot for your precious help!!!

 

I will keep you updated as soon as the Catalina update will be finished.

Jake Lo, thanks a lot for this! I tried your files and lost my brightness control, any idea how to fix this?

 

Thanks in advance for your help?
