I tested keymap in Karabiner. Numlock key is recognized as is by karabiner (and possibly macOS), however, it does not do anything (like you stated macOS does not support it). I have had the notion that numlock key is the feature of the keyboard, meaning, change of scan codes for numpad keys...

This could be a very basic configuration issue. Num Lock key is not working. In Num Lock off state (default and only state so far), numpad keys are Mac special keys (do not exactly know what they are). Is there a way to turn numlock on and off using your kext (@RehabMan)

Great Work @RehabMan This thread can be marked as 'solved' however I have one minor issue (copied from post#7): Keyboard Numpad is not working instead numpad keys are treated as extended or Mac specific keys. I have 2 set of brightness keys now. The ACPI keys and numpad 4/- for brightness +/-.

Fixed! Correcting CPU number fixed the issue. Thanks @the-braveknight I have 1 other minor issue: Keyboard Numpad is not working instead numpad keys are treated as extended or Mac specific keys. I have 2 set of brightness keys now. The ACPI keys and numpad 4/- for brightness +/-. @RehabMan I...

@braveknight I followed your guide and your repo at GitHub, this is the problem I am left with. Earlier I used to diagnose and debug problems on my own but current working environment restricts my time for the same, hence, I am no longer a tester for such things anymore. Appreciate if PR files...

After sleep/wake macOS is very slow and unusable. Audio sometimes distorts. The issue(s) seems similar to this thread: https://www.tonymacx86.com/threads/sleep-issue-after-wake-lenovo-ideapad-320-kabylake-hd620.255614/ I have tried VoodooTSCSync.kext but somehow it does not load. Using...

Any Update??

Yes I did. Even I had never seen this problem before. One of my friend has the same laptop. Same patches as me. Everything works on him. Shall I ask him for his ioreg? You may compare them, if that helps.

Can we do something about it? Webcam works fine under windows.

Rehab Any Update??

This doesn't help. Like I said before camera doesn't show up in system information. And sometimes console keep firing messages like "Found a Transaction which hasn't moved for 5000 milliseconds. Timing Out." or something like "Failed to enumerate a device on USB". Simultaneously...

Also, see if it helps. Usually Webcam works natively. Why it doesn't in my case?

Using v2.1

Hi Rehab, Since Mountain Lion I had not been able to use my webcam. I don't know why but I never really cared. Now things have. I need to use webcam and trying to figure out why it does not work. I have attached my IOREG. If you get time, please have a look. Thanks!!

This will come handy. Thanks!

Exactly the step I missed. How did you read that from IOREG. Amazing! Did the step and now Brightness is fixed. See update on above post. Thank you for the help. Well with SMBIOS6,2 the warning still pops up

Already did all the steps. What smbios should I use for Haswell? Yes I am using clover and its the clover which shows wrong ram. Chameleon is installed as alternate pbr boot. It shows correct info. Bu the warning comes to both bootloaders and the warning is from IOPlatformPluginUtil...

Of course I also get a warning about being unknown cpu model 0x45 so power management maybe incomplete. I don't know how or if it affects the system but the system does show wrong ram data. The ram is 4 gb but it shows 8 gb in About This Mac. Is is of any concern??

Now I got no clue where it came from. Device (GFX0) was there in the dsdt when I was looking for it to add _DSM method.

I didn't add device GFX0 in the dsdt I just booted in safe mode (-x) and extracted dsdt using DSDTSE app. Maybe Clover put there? Thank you for that. I will post back the results when I have them.
