antagon Posted October 23, 2018 Share Posted October 23, 2018 Hi, I´m trying to install High Seirra 13.6 to my E5470 with an I5 6440 HQ. Installation worked fine but now the machine boots sometimes and sometimes not. Attached is my EFI folder. EFI.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 23, 2018 Moderators Share Posted October 23, 2018 What error do you encounter when it doesn't boot? Don't see any patched DSDT/SSDT in your patched folder and you're not using hot patches. Link to comment Share on other sites More sharing options...
antagon Posted October 23, 2018 Author Share Posted October 23, 2018 DSDT/ Hotpatches: Yes I know usually I do this after I can boot the machine succesfully. My problem is, with the EFI i uploaded i can easily boot and install the machine. When I try to boot into the system the first time, verbose mode runs through until the graphics unit gets activated, then i just see the apple sign and boot stops. So i guess it is graphics related but i can´t figure out the problem. Moreover once in a while the machine boots flawlessly with full acceleration.

vampire.u Posted November 5, 2018 Share Posted November 5, 2018 This situation is generally the reason for the boot mode. Please change to AHCI Link to comment Share on other sites More sharing options...
