[Guide] 90% working Catalina on Lenovo Yoga 910 13IKB

[trs96]

any reason why you are not sharing? kind of pointless to claim it works otherwise.

Claiming that it works shows others that it's possible. They too can read, learn and study and apply that to get their own laptop working. It would be great though if ujaen-vcr helped others by responding to their questions about hacking this laptop.

Some of it was copied from this thread

Hi @smathead!

Thank you for sharing EFI!

Unfortunately I get the following error, trying to boot to my current Catalina. Could you please advise where to dig?

 

[smathead]

Sorry, all I really have to say is refollow the open core guide. I'm also a beginner.

@ujaen-vcr What was your process for getting the battery readout working on the Yoga 910 Opencore 11.1?

Hello,

Using VirtualSMC.kext and SMCBatteryManager.Kext

@ujaen-vcr any reason why you are not sharing?

Do you have screen rotation working?

Hello,

No, it's the only thing that doesn't work, the gyroscope. The multi-point function of the touch screen also does not work, it only works as a single point of the mouse.

Greetings

Hello,

Hello, I have shared my EFI numerous times, but the end I can not. I am delighted to answer the doubts and questions that any fellow forum member has.

Hello,

As the partner tells you, myself in the thread, go backwards from the last page, and you will see that I have shared my own EFI. With that folder, you will be able to boot your Catalina.

Greetings

Is anyone here experiencing a laggy/choppy feeling on the trackpad? It feels like a cheap chromebook.

Also, my trackpad just stopped working after an ota upgrade from 11.1 to 11.3.1. Any idea why? My efi and opencore is up to date, tried resetting nvram, and I also restarted multiple times.

Hi @smathead

I show you some screenshots that I have the latest version of OpenCore 0.6.9, all my installed kext and its versions that I have installed the latest version just like you, from Big Sur, 11.3.1. Tell you that the last version of VoodooI2C that works correctly for me is 2.6.3, 2.6.4 and the last 2.6.5 the trackpad does not work correctly.

Greetings and if you have any further questions, we are here to help.
