is there a tutorial you used for the ideapad 720s?

Everything has been self learned since 2017 when I bought this fantastic laptop!

I haven't had a lot of free time these days, but maybe at some point I can make some tutorial!?

I don't know if there are instructions in other forums?

@chris1111

Now looks non metal card  acceleration seems likely, hoping you work your magic for us non metal gpu guys.

Lenovo Ideapad 720s use Synaptic. Here is Kext if needed.

VoodooI2C.zip

 

You're using VoodooPS2Controller.kext with those I2C kexts, Right?  If so, we both have Synaptics trackpads but they must be different models.  Also did you try the Synaptics I2C kext and it didn't work?

Hey everyone I upgraded to Catalina and everything works so far, but was wondering I saw some people mention about high CPU power in Intel Power Gadget and mine is the same. When my laptop is idle my Power PKG stays at around 3.00. On Mojave it was sitting at 0.50. I compiled the updated CPUFriend for 10.15 and my frequency does go below 1.30GHz like it did before so wonder what is using more power.

 

My dGPU is still disabled through my SSDT-PTSWAK and other aml files so maybe it is because Catalina is still in beta.

Good news for owners of older non metal nVidia and Intel cards :thumbsup_anim: - see post#850 & updated post#938

Notes:

Hello all,

I have acceleration with @AsentientBot  fixes and most things work,\. Thanks to these developers my ancient hackbook seems good for another macos at least for now.

 

Only problem is in one of the track pad functions.

 

Almost all features in track pad work except the drag option.

I have checked this option in accessibility pane and used both vodoops2controller.kext and the i2c one posted in response to @mnfesq post couple of replies earlier.

Other features work, except only dragging/drag drop not functional.

Trackpad fully functional with vodoops2 in mojave.

 

Any suggestions/fix for this?

Thanks

Hmmb, different case on NVDA Fermi unfortunately.. -_- that's weird that GeForce, NVD*, IOAccel, IOGraphics, IOSurface, AppleGraphics.. all are loaded but having no acceleration on GT 520M (GF119), no dependencies issue appear on logs though.

Sidecar support on older Macs

renderTimingPixel.png

Not every Mac that supports macOS Catalina will support the Sidecar feature. I could not find any official info, but here are my own findings. There’s an explicit check that the Mac is newer than these models:

 

  • MacBook, MacBook Air: Early 2015

  • MacBook Pro: Mid 2015

  • iMac: Late 2015

  • Mac mini: Late 2014

  • Mac Pro: Late 2013

 

I managed to make Sidecar work with my Mid 2014 MacBook Pro work and iPad Pro. It’s great in terms of minimal lag, but the image quality is bad. I guess the limitation is about hardware HEVC encoding which requires Intel Core 6th gen processoHere’

 

If you need this feature on an older Mac despite low image quality I suggest filing a bug report with Apple. A hidden option to disable such hardware check would be great.

 

That requires disabling System Integrity Protection and editing SidecarCore private framework to exclude your Mac model from the blacklist.

Edit: To enable unsupported Mac and "display" devices use this Terminal command:

defaults write com.apple.sidecar.display AllowAllDevices -bool true; defaults write com.apple.sidecar.display hasShownPref -bool true; open /System/Library/PreferencePanes/Sidecar.prefPane

I had discovered the AllowAllDevices settings before writing this post, but for some reason it did not have effect at first so I resorted to patching the files. Looks like the patching is not needed.

      I would like to try to install Catalina on a 64 GB flash drive, in order to bypass the SATA issue. I so thay many managed to do that on external SSDs.
      Actualy, already tried it. The first step finished ok, just it took much longer. After first booting from the target flash drive from the installing flash drive, it blocked on something like ”installer will create a non-removeable partition”. Perhaps if I waiting long enough, I would have passed that phase, but there were already some 15 minutes since it blocked.
