ltooz_audis Posted October 30, 2017 Share Posted October 30, 2017 There are 2 types of black screens after wake up: 1 is actually wakes up but the screen back brightness is set to lowest because there's no back light control in macOS High Sierra. 2 is the ACPI power management is not patched correctly.
