ITzTravelInTime Posted October 4, 2017 Share Posted October 4, 2017 Try boot args to enable LILU and wathevergreen on high sierra Link to comment Share on other sites More sharing options...
tomnic Posted October 4, 2017 Share Posted October 4, 2017 You should try a script that puts your hackintosh to sleep and wakes it up automatically when booting... a dirty hack but better than replacing the framebuffer kext with sierra's one Link to comment Share on other sites More sharing options...
