Baio77 Posted July 19, 2021 Share Posted July 19, 2021 3 hours ago, lamatta17 said: Hello Baio77, Thank you very much for your support. Have now tried the following: 1. BIOS settings like: https://osxlatitude.com/forums/topic/11477-7490-bios-settings/?tab=comments#comment-90318 2. copied your EFI folder to internal SSD. 3. started 4. nvreset 5. started Result: no sound, no touchpad, no sleep, no Thunderbolt started another time with nvram-reset no success. Does it make sense to do a complete reinstall with your EFI? here still the ioreg with your EFI MacBook Pro von Birne-Bajo77.ioreg 5 MB · 1 download Ok ioreg says that GPI0 is NOT active so no working trackpad, you have to extract ACPI from Bios via EFI Debug OC, I leave it here, put it in USB and start os already installed, after all the verbose, you pass me the extracted files SysReport and the log file EFI Debug 0.7.1.zip Link to comment Share on other sites More sharing options...
lamatta17 Posted July 20, 2021 Share Posted July 20, 2021 Hello Jake Lo, I have tested your EFI. Result: - Sound and microphone work. - Camera works - Trackpad works, but pointer is very slow despite max pointer speed. - The touchpad buttons do not respond (all 4). - Sleep mode works. - Volume control works with F2, F3 and F4. - Brightness cannot be controlled with (Fn) F11 and (Fn) F12 - Thunderbolt is not present Thanks for your efforts Hello Baio77, have generated the data with your Debug-EFI. Thanks for your time. SysReport.zip I have tested a little further. a monitor connected to HDMI is not recognized. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 20, 2021 Moderators Share Posted July 20, 2021 Try this, add the SSDT and replace the Config file I think it's known for the mouse keys not to work for this model. No fix found so far. Thunderbolt is not supported with my file. You might need to add additional patches. fixFnKey.zip Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted July 20, 2021 Moderators Share Posted July 20, 2021 For HDMI, plug in the monitor and launch IORegistryExplorer.app v2.1, not 3.0+ Save, compress and paste it here Link to comment Share on other sites More sharing options...

lamatta17 Posted July 20, 2021 Share Posted July 20, 2021 Hi, have connected the HDMI monitor. changed the value and restarted. HDMI monitor remained dark. Unplugged HDMI connector and plugged it back in. Shortly after that the picture was there. Funzt (is german for works) many many thanks now only Thunderbolt and the trackpad is missing, then I am happy Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 20, 2021 Moderators Share Posted July 20, 2021 check out Hervé's guide, he also mentioned that trackpoint and mouse keys are not working. You can use tab to drag or 2 fingers to right click. There's really no good support to Alps I2C touchpad, only some basic movement. The USB-C port should work with external display though ... usb-c to DP port, but not much support there for thunderbolt. Link to comment Share on other sites More sharing options...
