Black Screen when Wake from Sleep on Dell Precision T7610

Recommended Posts


When I Attempt to wake my Machine from sleep, the screen stays black, although the computer is obviously awake !

This Machine has a 1300W Power Supply So Sleep is Very Useful.


I Tried:

1) FIX_WAK and FixShutdown as per Clover Wiki.
2) Although I am using "SAPPHIRE Radeon PULSE RX 580 8GB GDDR5", which Should be completely Supported by Mojave, I Also changed the Part Number to "113-4E353BU-O4E" as per this Guide: http://www.xlr8yourmac.com/archives/feb18/RadeonRX-580_MacPro.html. The GPU is working GREAT without even Clover Inject

3) Tried to Run this command: disablehibernate.command.zip

4) Tried darkwake=0 to 10

5) Disabled wake on USB & Wake on LAN (BIOS)


sudo pmset -g

Hi SavageAUS,

Yes, I Tried with "Lilu + WhateverGreen" and without but i got black screen both ways !

I Can See that you do have "Sapphire NITRO+ Radeon RX 580 8GD5 Special Edition", is sleep working fine ? and do you use "Lilu + WhateverGreen" ?
also it would be great if you can share your clover configurations !
