Sorry for the question, but where do I get my AML when my notebook is not on the list? When I use just some generic file, will it work?

onemanosx · March 25, 2019

Sorry for the question, but where do I get my AML when my notebook is not on the list? When I use just some generic file, will it work?

if your notebook is not in the list, you will then need to do your own custom patch

Wizzard · March 25, 2019

I understand, but when I use given example AML, it means that all unsupported notebooks will use this AML as well so they should use the same patch?

onemanosx · March 25, 2019

The example aml is meant for tutorial purposes. You shld use your laptop dsdt file. Method is same for most laptops.

Wizzard · March 25, 2019

Okay, so I can get my DSDT.aml from RunMe app, right? I tried to patch it accorging to guide, but do not have battery status yet. What could be wrong?

No idea. For a start you can upload a full dump using run.me app and try to explain in steps what you did.

Wizzard · March 26, 2019

This is my older dump, I think it is the same as the latest. I just followed the instructions and had no compile errors.

Send me MacBook-uzivatela-Wizzard.zip

onemanosx · March 26, 2019

no compile errors doesnt mean patch is done correctly. I cant help if you wont share what exactly you did. Maybe you can share your 16 bit integers and how you solved them.

Wizzard · March 26, 2019

Thanks much, I will check at home and upload everything.

onemanosx · March 26, 2019

This is my older dump, I think it is the same as the latest. I just followed the instructions and had no compile errors.

You did not have patched DSDT in clover/acpi/patched folder. Neither do you have any battery kext in your clover/kexts other folder.

Cant expect things to work without these 2 items.

Wizzard · March 26, 2019

That was my first dump without any patches, I will upload my actual later today. Thanks much.

Wizzard · March 26, 2019

This is my current dump. I dont know where is my patched DSDT, because I would swear that I have copied it yesterday

Send me MacBook.zip

onemanosx · March 26, 2019

[ref]Wizzard[/ref], place DSDT in clover/acpi/patched folder. Reboot and generate new send_me.

Thank you very much, it still shows 0 percent, but at least it seems that since upgrading to 10.14.4 the computer is not so hot like before.

Send me MacBook.zip

onemanosx · March 28, 2019

[ref]Wizzard[/ref], try rebuild cache and permissions. Battery is detected well as per shown in ioreg though.

Tried that in Kext Updater, but it does not seem to help
