No luck with Big Sur (11.6.1) and Monterey (12.3) - can I help you fixing it? #4

Closed PierreMarieBaty closed 2 years ago

PierreMarieBaty commented 2 years ago

Hello Mattia,

Congratulations for having putting this together. Are you still using this laptop ? I'm afraid an update is necessary...

Laptop model: EUL-W19P (same as yours) BIOS: downgraded to 1.04 (same as yours?) with CFG-Lock and 64Mb DVMT patches applied (using RU.EFI)

1 - When trying to install Big Sur (version 11.6.1) : 1.a - When using your latest EFI release from 17 june 2021 (with a properly generated and validated MacBookPro16,3 PlatformInfo as you suggested)

2 - When trying to install Monterey (version 12.3) 2.a - When using your latest EFI release from 17 june 2021 (with a properly generated and validated MacBookPro16,3 PlatformInfo as you suggested)

Could you please confirm (or infirm) whether you're still interested in all this ? I would very much appreciate your help so as to get this SMC/EFI stack working again for this very laptop. As for the background, I'm an experienced programmer, although a bit new to all the OpenCore/hackintosh jargon, so you can talk me technical - it shouldn't be a problem.

I am definitely interested in having this fixed, and you have my word that I'm not the kind of user that goes away and lets you down when I find a solution, I am committed to stay here and collaborate with you until we can confirm here a proper resolution :)

If you need me to provide you with anything - just ask.

I'm adding a follow-up here. The NVMe SSD installed in this laptop is a Samsung PM981a MZVLB512HBJQ 512Gb.

Well, if I am to trust https://dortania.github.io/Anti-Hackintosh-Buyers-Guide/Storage.html then I have an unsupported SSD.

This would explain problems 1a) and 1b).

An interesting thread to read on this topic: https://github.com/tylernguyen/x1c6-hackintosh/issues/43

It suggests that not all models of EUL-W19P laptops have the same NVMe SSDs. I'd be interested in knowing what SSD model you have in yours ?

edit OK, I won't hope for a software fix, so I ordered a WD750 WDS100T1B0E. This laptop is rather simple to open (there are 4 extra screws under the rubber pads), then swapping the SSD is just a matter of unscrewing the lefthandmost screw on the copper plate, unscrewing the NVMe SSD that's just below, and carefully sliding it left.

Now if someone has a clue on problem no 2 (Monterey) ?

tmbt78 commented 2 years ago

Hi, i still have the laptop and still using it on Big Sur. I've kept my EFI updated with the latest kext and OC and doesn't have any problem. I'm not interested in Monterey at the moment and never tried to install it on this laptop.

As soon as i've time i will update the repository so you can give a try to the new EFI. My NVME drive is this : KXG60ZNV512G TOSHIBA

PierreMarieBaty commented 2 years ago

Hey, thank you for your reply. So it confirms these laptops can be fitted with different SSDs. I suggest you to add a prominent note in your readme that the PM981a ones should be swapped. I can provide photos on how to do that.

I expect the new SSD to arrive tomorrow or the day after ; I'll renew my attempts then and I expect success at least with Big Sur. May I ask you why you did not upgrade to Monterey, is there a technical or philosophical reason ?

PierreMarieBaty commented 2 years ago

So, the new WD SSD arrived today and was promptly fitted in place. Big Sur installed. No issues so far edit: one issue (minor): your EFI uses the Airport version of the Intel Wifi driver, which is supposed to work OOTB. But I couldn't connect to my 5GHz AP with it. After switching to the last stable version of itlwm.kext (Ethernet version) + the Heliport app, Wifi works again. You should add a note about that too.

Also, I re-enabled SIP in the config.plist (csr-active-config -> 0) as some software require it to function.

Monterey still doesn't boot however, but now I can take time to study that more closely.

PierreMarieBaty commented 2 years ago

Something else isn't working right: the automatic screen backlight adjustment. Have you toggled it off ?

tmbt78 commented 2 years ago

I don't any problem with screen backlight. If you've updated OC you Need to update the backlight aml accordingly.

Thank you for the reminder.

Well, the issue with the automatic backlight control seems to have disappeared and I couldn't find neither the reason why it appeared nor what made it disappear. The backlight was shifting up and down at random while I was typing and I noticed that the control keys for backlight and audio weren't working. One reboot later, these symptoms disappeared.

Unfortunately not everything is fixed: when I leave the laptop for a few minutes and the screen goes black, nothing seems to be able to make it light up again. It's not frozen: I hear macOS playing the "bloop" sound when I hit the space bar. It's just that the display fails to wake up.

edit thinking about it, it might be because I switched to a MacBookAir9,1 platform info, thinking it would be wiser regarding to the laptop's specs. But that was at first sight. When looking at it more closely, the CPU/GPU architecture (Comet Lake + UHD620) is perhaps closer to a MacBookPro15,1/15,3/16,1 or 16,4 (Coffee Lake + UHD630) than of a MacBookAir9,1 (Ice Lake + Iris Plus). Alright - let me switch back. edit 2 - it wasn't that. I'm still on MacBookAir9,1 and the problem disappeared when I started over from an EFI backup. I'm forced to conclude that the precompiled SSDT files from Dortania (which I updated following your advice) are not totally compatible with this laptop.

Also, I'm wondering if your readme is up-to-date with your EFI. Because in the readme you say the touch screen is disabled via an ACPI patch, whereas here it's working, seemingly totally fine ?

In a nutshell, my changes:

As you seem much more knowledgeable than me on this matter, if you could take the time to upload your latest EFI I'd be very interested in starting over from there. We'd have a common base to start with.

Monterey installer boot success ! The culprits were the Bluetooth kernel extensions. I had overlooked that in Monterey the Bluetooth stack was moved from kernel to user space, and that the previous methods of uploading the BT firmware to the cards were not only no longer effective, but could cause the OS to fail to boot.

My solution was as recommended by the OC user guide to use the MaxKernel and MinKernel values to provide a selective way of loading the kernel extensions, i.e.:

Now installing.

tmbt78 commented 2 years ago

The black screen Is totally normal in most Huawei laptop. I've created an acpi patch to fix that. I Will try to update my GitHub with the latest version but meanwhile could you upload here your untouched aml files? Use patchmatic -extract to do that.

Here you are. Let me know what interesting findings you discover - and thanks again.

BTW, Monterey installed fine and things seem to work as good as with Big Sur. The touchscreen still works. Irrelevant question but, is there a possibility to wake up the laptop by hitting the touchpad instead of hitting a key ?

tmbt78 commented 2 years ago

I will upload in few minutes my latest EFI. I didn't have time to upgrade OC to the lastest version or the latest kexts but everything is working fine. I'm using some framebuffer patches to fix the problems i had with the Type C port when used as HDMI so switching to another SMBIOS will probably broke them due to different connectors type.

PierreMarieBaty commented 2 years ago

Thank you. I'm going to make a diff with mine so as to highlight the changes.

Right now everything seems to work in Monterey. I'm curious about the webcam not working, do you have an idea why ? Normally UVC webcams should work out of the box. I've read somewhere that MJPEG decoding on USB2 transport (which seems to be the case here) was broken in Monterey but it's been fixed since, and besides it was reported as nonworking in Big Sur as well, so the cause must be elsewhere.

PierreMarieBaty commented 2 years ago

As for the issue proper, I guess you can mark it as resolved. The problems boiled down to this:

  1. Some of these laptops come equipped with PM981a SSD which are very badly supported by macOS. They need to be swapped.
  2. In order to boot, install and use macOS Monterey, the BlueToolFixup.kext extension needs to be added with a MinKernel value set to 21.00.0 AND a MaxKernel value of 20.99.9 needs to be added to the IntelBluetoothInjector.kext one. After that the same EFI can be used on both systems.
tmbt78 commented 2 years ago

About the webcam i've tried lot of tricks and kexts but without luck. My theory is that in this laptop the webcam is connected over USB in a way that is not supported by MacOS. Usually as you can check in some forums they say : or it works OOB or it doesn't work at all. I've tried injecting various kexts but without luck. According to Rehabman when MacOS doesn't show the webcam serial number under About this Mac (which is my case) then the webcam doesn't work. I gave up on the webcam because in my opinion it will never work

how to do it? please guide me !

PierreMarieBaty commented 1 year ago

Hello

How to do what ? Swap the SSD ? Or something else mentioned in this thread ?
