Trackpoint not scrolling with middle-click

Do you have any issues with your trackpoint not scrolling properly when you hold the middle mouse button?

I tried upgrading VoodooPS2Controller.kext to the latest version, but it still isn't working.

I'm pretty new to the hackintosh scene, so if you'd have some suggestions on where I can poke around to figure out why isn't not working, I'd appreciate it!

Making a new ALC285 layout for 7th gen

I finally had the time and the balls to go ahead and make a new layout! yay?

I had some problems with the layout 71, mainly,
i) headphone sometimes goes all weird, sleeps solves it for a while.
ii) in-line mic doesnt work.
iii) internal mic doesnt work

with layout 88, I had a better success with in-line mic and headphone consistency but there were no double speakers in it.

So, I followed this particular guide: https://github.com/5T33Z0/AppleALC-Guides/tree/main/AppleALC_Layout-ID

Platform71.xml is absolutely correct for our codec. All nodes are correctly configured.

So it seems that the magic will be in pin configuration.

This is the default configuration from codec dump. (After removing disabled devices and using predefined fixes.) This config works pretty good, removes first two problems. Although we still have two speaker outputs and no luck with the internal microphone.


For making a 4 channel speaker setup, I tried to put speakers into same group(G) with same number. There were still 2 speakers and they didnt work together. Also sound was distorted somehow.

For adding internal microphone to pin configurator, I used the values from layout 71 and added a second input. It had the correct nodes, also didnt work.

Strange part is, there is only one input when I use the codec_dump.txt. I created another dump with opencore debug and it is still the same

But as you can see from the schematic, there are 3 inputs(red circles).
Other notes regarding the schematic,
Node 20 is top speakers and they work together with jack detection.
Node 23 is bottom speakers.

Maybe they can work to make two speakers in 4 channel.

So I am out of ideas, our schematic looks very different than the one in the guide and I have no deep knowledge about any of it.

Yet I believe this version that I compiled works better than layout 71.
Here is the kext if you want to try it
AppleALC-1.7.6-RELEASE.zip

Layout ID is 77

Let me know if you have any ideas

Bluetooth microphone

Does a microphone (earphones with a microphone) connected by bluetooth work?

OC version?

Hackintool says that the version is 0.6.6, and OCC for 0.7.7 warns it is not compatible with the config file?

No Graphics Acceleration / NVRAM

After getting Monterey installed by removing the device-id entry in the config.plist outlined in #5. I notice that inside About This Mac, it states I only have 7MB of VRAM and all display is laggy. I tried adding the entry back but it won't let me boot so I removed it again. It seems like without the entry some kext might not be applied causing the low VRAM issue. Any workaround from adding it back?

Microphone

Do you know how to fix the internal microphone

SSDT-Batt

I just installed Mac OS 12.3 with your EFI, but there is no battery in the preference setting. Is the SSDT-Batt file on github the correct working version? Thanks.

HDMI not working with `-igfxmlr` boot flag

Hey @seven-of-eleven and @penholderu, great news, so I took the latest default config.plist from the repo and removed -wegnoegpu and added -igfxmlr and was able to boot with graphics acceleration.

However, connecting to an external monitor doesn't work for both direct HDMI connection or USB-C dongle connection.

@penholderu any luck with external monitor connections?

Internal sceen goes black after plugged HDMI

Hi,

Firstly, I would like to express my sincere gratitude for your repository. It has greatly saved me a significant amount of time.

I am using your configuration with my X1C7 FHD i5 8th version. The display seems to work fine. However, when I plug in an HDMI cable, the external monitor works fine, but the internal screen goes black. Even after removing the HDMI monitor, the internal screen still does not work.

Moreover, the internal screen sometimes goes black after the Apple Logo disappears during the booting process, but macOS is still up (keyboard caps lock and notification audio are working fine). I have to force restart or connect to an external monitor to restart my laptop.

I am a newbie, and after Googling a lot, I think the issue may be related to the device-layout-id or frame-buffer configuration.

Could you please help me solve these issues? Thank you.
