Glenn Posted October 18, 2019 Share Posted October 18, 2019 My Specs: M4800 Dell Precision (as MacBookPro11,2) Intel Core i7. 2.69 GHz Memory: 16GB (2x8 DDR3) NVIDIA Quadro K1100M - 2047 MB 250GB HDD - El Capitan SSD 240GB - High Sierra Sat 1600, hello... I am in very much the same position as you: I made full use of Frankenstien's EFI - for which many many thanks to h!m. I changed only the SMBIOS entry to suit my machine and, like you, find that trying to Sleep (Apple menu/Timed in SysPrefs/Fn+F2) causes immediate black screen followed by complete power-off shutdown. I'm wondering whether you have since come upon a solution? (Or maybe somebody else is able to help out)? I would be very grateful, for (almost) all else works perfectly.
