Touchscreen does not work E5450

[kaem-e]

I followed the README.md files instructions to enable all voodooI2C kexts for touchscreen functionality but it does not seem to work

Did you disable VoodooPS2's VoodooInput?

Did you disable VoodooPS2's VoodooInput?

yes i did

I assume you tried OpenCore 0.7.9. Can you try with the previous EFI version? https://github.com/SkyrilHD/Dell-Exx50-Hackintosh/releases/tag/v2.4

I wonder if the new VoodooI2C update is broken.

just tried it it doesn't seem to work either

Hmm. Can you double check if touchscreen support is enabled in BIOS (if there is any). Since I don't have a touchscreen model, I cannot test what's wrong.

Can you send an IOReg btw, so I can check if VoodooI2C is loading at all.

i dont think an option for enabling the touchscreen exists in the bios though i am certain it is enabled as i can easily use touch to move the cursor within the opencore boot menu (as well as a dual booted linux install). Seems to be MacOS in particular that doesn't want to detect it,

Here's the ioreg output (github gist) IOReg.txt

I don't see any entry for I2C. Can you send an unmodified DSDT grabbed from Windows or Linux, e.g. SSDTTime. Also use the IORegistryExplorer I linked in the comment before.

[kaem-e]

yeah sure, here (github wasnt allowing me to upload the .ioreg and .aml files so i uploaded it to anonfiles) https://anonfiles.com/Fbeb49N7xa/Kaem_s_MacBook_Pro_2_ioreg https://anonfiles.com/J2ha47N3xc/DSDT_aml

Can you try the latest master? Touchscreen should now be fixed.

[kaem-e]

Yup! seems to work perfectly now, gestures and everything
