kidalive Posted August 9, 2014 Share Posted August 9, 2014 I recently installed a kext called BTFirmwareUploader. After that, every time at login window I get distorted flickering screen, I have to turn the display off and then turn back on to make it work normal. How to deleter this {censored}? The author claims it upload the BT firmware. I think it overides a startup item, I need to restore it to normal. I installed version 2.5 and removed the kext, but the issue is still there. I think it is a script to make it start-up every boot. The situation is just like below. Link to comment Share on other sites More sharing options...
bronxteck Posted August 9, 2014 Share Posted August 9, 2014 it looks like your screen resolution is too high for the screen or a video frame buffer issue. it might have been triggered by a cache build when installing the kext Link to comment Share on other sites More sharing options...
