Put these two files in CEVER

Hi @807133286, you are the best !!!!!!! They work (both the touchscreen as the advanced gestures of the trackpad). Many thanks!!!

Here I leave some observations in case you are useful:

1- TRACKPAD:
Almost all advanced trackpad gestures work, only these are it ones do not recognize yet:

• Smart Zoom
• Notification Center

NOTE: It is very difficult to make these two gestures ("Show Desktop" and "Launchpad"), I suppose it is due to the size difference of the trackpad.

2- TOUCHSCREEN:
Although you can already recognize the touch with your fingers, you can not make any gesture(like in this video or this video), except select an icon, click, or select several icons.

Anyway, it's a big step forward, every time there are fewer devices left without working, thank you very much !!!!

[807133286]

@eamigo86 Perfect now

[eamigo86]

Hi @807133286, did you update the files with any new settings?

[807133286]

@eamigo86 update the files with new settings

[eamigo86]

Hi @807133286, could you tell me what files you updated? The two original zip files are the same, at least functionally???
Thanks in advance and congratulations for the New Year!!!!

@807133286 Could you please explain how does it work？

[wtdcode]

@807133286 Also, it seems that the dragging and selecting text gestures are not working.

[wtdcode]

@eamigo86 I get a KP when trying to make a "Show Desktop" gesture even I have disabled that gesture. How about you?

[eamigo86]

Hi @wtdcode, it works pretty well for me, except for the size of the trackpad that is small compared to that of a traditional mac, so it is uncomfortable to make it work well at all, but I do not throw any KP to me

[wtdcode]

@eamigo86 So you mean you can make a "Show Desktop" gesture without getting a KP? Even trying to spread your fingers from the center of the touchpad by design? BTW, other gestures for me are easy to make, I will try to check why it panics later.

[wtdcode]

Strangely, when I decide to find out why it panics, it starts to work well now...

@807133286 Is this using interrupt or polling mode? Thank you!

@kevinshroff - I'm seeing this line in the boot logs:

localhost kernel[0]: (VoodooI2CHID) <VoodooI2CHID`VoodooI2CHIDDevice::handleStart(IOService*)> VoodooI2CHIDDevice::WCOM488F Warning: Could not get interrupt event source, using polling instead

Having captured those with:

log show --predicate 'process == "kernel"' --style syslog --source --debug --last 10m > ~/sys_log.txt

I see, so we should expect to see some increased power usage when using these voodooi2c files until interrupt is ready for Coffee Lake. On the upside, when I tested voodooi2c with the provided files the gestures work flawlessly

could we be more specific on where to place which files, my tracked pad stopped working.

Did you update your BIOS? You should downgrade to 1.5.0 if you did. 在 2019年1月18日週五 上午3:52，Mathew <[email protected] 寫道：

@Raymonf Maybe not, my bios is 1.6.0.

@mathewjpotter Just put kexts into kexts/Other folder and aml into acpi/patched folder.

[Raymonf]

@wtdcode Oh, okay. Good to know that this is BIOS version independent.

[jvdtoorn]

Installed these, but right clicking/tapping (2 fingers) is not working for me. Does anyone have the same issue?

[senatore412]

Same here
