Like many others in the community, I am running a Samsung NVMe drive in my Late 2013 15 inch Macbook Pro. [Thanks to the firmware update provided in 10.13 Macs back until around 2013 can work off of a NVMe drive natively] (Credit to Gilles) 1.

I used a Chenyang NGFF to Apple 12+16 adapter and formatted the disk in Disk Utility in the installer to APFS, then installed the system (10.13, initial release). Note that before wiping and reinstalling the OS, I had previously upgraded to High Sierra.

Speed wise I am getting about 1400MB/s read and write speeds. I am stating all of this to show that the drive itself works great, except for deep sleep mode feature. It cannot come out of deep sleep mode, it just shows a black screen. Anyone happen to know of a fix? I have read that it could be due to the drive not powering on in time for the SMC to find it. If no fix is likely, what workarounds are there? enter image description here

  • I don't think it's related to your particular setup. This answer seems to imply that it's a known issue. This discussion indicates the same symptom on a MacPro. – Allan Oct 3 '17 at 13:49
  • What drivers / firmware is on the NVMe and does the vendor have a patch / support for Apple controllers? – bmike Apr 1 at 11:47

Please try this. Before try, Please check yourself about pmset, and if you like this then try.

open Terminal in Utility folder in Application folder.

pmset -g  

(a list shown that is pmset setting)

sudo pmset -a hibernatemode 0 standby 0 autopoweroff 0

(administrator password is needed)

This command makes a Mac never hibernate or deep-sleep.
