jones333333 Posted October 28, 2020 Author Share Posted October 28, 2020 The laptop restarted after update was done. I can get to the Opencore boot menu but after that I get a kernel panic than the white apple logo appears white a 3/4 full progress bar and keep hanging. Do you know how you can boot in verbose mode with OpenCore ? Thanks in advance for your help Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 28, 2020 Moderators Share Posted October 28, 2020 add -v to Config file under NVRam/Add/7C436110-AB2A-4BBB-A880-FE41995C9F82/Boot-arg or like a realMac, boot into recovery mode Quote Link to comment Share on other sites More sharing options...
jones333333 Posted October 29, 2020 Author Share Posted October 29, 2020 Jake Lo, I think there was an issue with my Catalina installation during the update. I did a complete recovery of OSX using the recovery assistant and could finally install Catalina on this laptop. Thanks again for your precious help!

jones333333 Posted October 29, 2020 Author Share Posted October 29, 2020 Jake Lo, I lost my brightness control also the automatic backlight control. Do you know how to fix this? Also when the laptop wake up, the trackpad loose the scrolling functionality. Another question regarding my SMBIOS. With my kind of processor i7-410U shoul it be better to use another SMBIOS like one for MacBook Pro? Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 29, 2020 Moderators Share Posted October 29, 2020 Yes, try using MBP11,1 Try resetting NVRam on OC picker. Quote Link to comment Share on other sites More sharing options...
jones333333 Posted October 29, 2020 Author Share Posted October 29, 2020 Jake Lo, I did try to reset the NVRam but this doen't fixed the issue of the screen brightness. Also I think that my trackpad is a Synaptics one, maybe I am using the wrong kext? Quote Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 29, 2020 Moderators Share Posted October 29, 2020 Try switching back to an older version from your Clover files. I think I switched it to 2.1.7, you had voodoops2Controller 2.1.5 Quote Link to comment Share on other sites More sharing options...
jones333333 Posted October 30, 2020 Author Share Posted October 30, 2020 Thanks JAke Lo! Regarding my backlight issue, do you have any idea what is causing this. My brightness level control and also automatic brightness level were perfectly functioning with your files on High Sierra. One last question: this XPS have a touchscreen (L2C I think) is there any possibility to make it working like on my Lenovo Yoga ? Thanks in advance for your help!
