[doublepost=1519783972][/doublepost]Hi I installed Samsung NVMe M.2 ssd on my MBP 2015. It is booting up well (from Shut Down) and I can see my new hard drive and everything (installed High Sierra). I bought the sintech adapter and taped it with kapton tape and still having issues when rebooting (from Restart). I get that blinking folder with "?". I also did disable sleep mode with "sudo pmset -a standby 0" and still getting that annoying blinking folder when trying to wake up. Is there anything else I should do? Please Help!!!
Thanks in advance
My experiences so far with the following setup:
MBP Mid2015 2.8Ghz DG 16GB
Samsung EVO 960 1TB - Firmware 3xxxxxxxxx
Currently I have restored all the power settings to their default values. I was using pmset sleep 0 on my 2014 MBP but since upgrading to the 2015 this seems not to be necessary anymore.
So I am using this MBP daily just waking from sleep without problems. The computer is fast using PCIe 3.0 4x lanes so around 2500Gb/s read and 2Gb/s write.
I have a 250GB bootcamp with windows 10 on it - and occationally i reboot into this and then when I reboot back into MAC OS it gives Kernel panics randomly.
I have also experienced that if you wait after successfull reboot it might crash with a KP.
But if it survives say 30 min then I see no more KPs and the computer can go to sleep and wake and so forth.
I am hoping Samsung releases a firmware version 4xxxxxx that resolves this boot issue - im currently running 3xxxxx firmware on the EVO 960.
I am using verbose mode on startup in order to follow the boot process - and it seems to help in the boot process - I do not know why.
sudo nvram boot-args="-v"
