At least on my MacBook Pro retina late 2013 the DEVSLP pin is NOT CONNECTED on the internal Apple connector (you can see this on the schematics), so there's no sense in trying to connect the pins on the adapter ...

Problems with sleeping and rebooting on Mac 2013-2014 and NVMe disks take up this (DEVSLP pin is NOT CONNECTED). I think so.
@armoured, battery drain with the 256 GB 600p in hibernation mode was about 1 to 1.5% per hour.
One hour of use with Safari, Mail, streaming radio via iTunes used up 18% (71% to 53%) and Bluetooth off. I did not make any changes to the OS after installing High Sierra and upgrading to 10.13.2 this morning.

Thanks. That does sound a fair bit more intensive battery usage. Is this specific to the Intel or similar with others? I'm kind of leaning to the Kingston right now.
Hi,
I think you didn't follow the advice to install High Sierra on the original Apple SSD.
you have to install High Sierra first on the original Apple AHCI ssd, which is the only way to have your BootRom updated.
Once you have done that and your BootRom is up to date, you can put back the NVMe SSD and then it will work reliably.
With that amount of battery drain, I would get about 4.5 hours of run time which is fine for me. I think all of them will drain the battery more quickly than the Apple ssd but it's something I can live with.
Search the thread for other people that have used the Kingston KC1000. I went with the Intel because it was so cheap compared to the 960 EVO and other drives, especially an OEM Apple drive.
Another issue seems to be the black adapters that are being sold by Sintech in place of the large, green adapters.
Dagoth,
On the large green adapter, it looks like DEVSLP on the ssd side is connected to SSD_PWR_FET_EN on the apple connector side.
Are you saying that will solve the sleep problem with the black adapter.
Thanks
Ravi
I got the black sintech adapter in the mail and as expected from previous posts, I still have the sleep problem.
But everything else with this adapter works well and is plug and play given the kapton tape.
I am using a Samsung PM961 on a MacBook Pro Early 2015. I do not have another nvme to try. I can get my hands on a Toshiba XG4. Wonder if that will have sleep problems too.

100% agree with that statement and findings. I am seeing he same behavior with PM961 which is very similar to 960 evo and a black sintech adapter.
I am really hoping that a kext update becomes available and will make this a little better.

Ok, I don't know all factors but the settings below seem to work for me in terms of sleep/standby without issues with the black sintech adapter.
changed hibernatemode to 25 and standbydelay to 5 seconds
More testing is required. But almost makes me think that standby works but sleep does not.
Also, I found that the DeepSleep app can successfully put the MacBook Pro in hibernate and bring it back without any issues too.
This is my peseta -g response.
System-wide power settings:
Currently in use:
standbydelay 5
standby 1
halfdim 1
hibernatefile /var/vm/sleepimage
powernap 0
gpuswitch 2
disksleep 0
sleep 20
autopoweroffdelay 28800
hibernatemode 25
autopoweroff 1
ttyskeepawake 1
displaysleep 10
tcpkeepalive 1
acwake 0
lidwake 1

Uhhh - very interesting indeed! Might this also fix the 960 EVO drive that I have installed in my MID 2014 MBP 15"
I have KPs during start from completely off - and very seldom KP during work (Large Green sintech adapter)

Much thanks. Adapter will likely be the biggest issue - not sure what is available or what I'll get, and seems like a bit of a carpshoot.
I'll look into the Kingston. I guess the battery issue 'is what it is' and not much of a separate decision point.
Doing a bit more research here, it seems my macbook air (2014) is unlikely to use the 4-channels, and so buying on basis of speed shouldn't be priority - so the intel sounds good and cheap.
I updated my system to High Sierra on the original Apple SSD. It doesn't seem to be the cause of my install problem (instead I would say a boot issue during install process).
Now the system is working fine, on a late-2014 Macbook 15" with black Sintech Adapter.
But when I start up the Macbook, I have to hold on "option key" to select the SSD drive, otherwise folder icon with "?". Any idea how to solve this small issue?
When it hibernate after sleep mode, I have to force shut down? Does the solution be to avoid hibernation in Terminal?
Hey Guys ! What is your opinion, which ssd will be best for MBPr 13 early 2015. As I read all forum here 960evo with some problems, intel with the fast battery falling, about Kingston don’t know. I’ve order 3pc’s of adapter, two from AliExpress, one from syntech, I’ve message them to send me newer bigger green model. Thanks for advice !
Why do you say that?
Every MacBook Pro / MacBook Air from 2013 to 2017 are able to use 4 PCIe lanes, at PCIe 2.0 speed
The only one to have PCIe 3.0 speed is the rMBP 15" mid 2015
Also, only some desktop mac models have only 2x lanes wired : the Macmini7,1 (mid 2014) and the iMac14,4 (21,5" Mid 2014)
A lot of people here got only 2x PCIe lanes because adapters were installed without proper insulation (kapton tape).
Once proper insulation was applied on the back of the adapter, a 4x lanes link was available

Ok sorry... I must have misread something, I thought you still were in Sierra on the original Apple SSD before to install the NVMe SSD.
just to make sure, can you just tell me if you have this BootRom version : MBP112.0142.B00 ?
Both problems need the two following solutions :
- as for startup / reboot issue, sorry but the solution may be to get a "large green" sintech adapter, not the black one
- as for sleep/hibernation issue, the solution is to prevent hibernation by typing "sudo pmset -g standby 0" in the terminal
[doublepost=1517931339][/doublepost]
It seems that problems with Samsung SSD are now gone with both using APFS and being on 10.3.3 at least.
Sintech doesn't ship any large green adapters, which is a problem...
Thank you so much Giles ! I think will go for 1tb 960 evo. About adapter it’s so sad what about a new version of adapter ? Any issues with it ?
I just received a large green adapter last week if that helps. I ordered on Jan 9th though.
I am using a Samsung PM961 with a Early 2015 MBPR and black sintech adapter. It is pretty stable with the sleep settings I posted above.
PM961 is a OEM version of the 960 EVO.
Hi Gilles,
My BootRom version is MBP112.0142.B00
Many thanks for your guidance about start up & hibernation since I wasn't sure. But as I have only concern with hibernation, the terminal command would be : sudo pmset -a hibernatemode 0 ?
Except for booting & hibernation, the Macbook is stable and works flawlessly.

Thanks for reply !
So you recommend me to take PM961 instead of 960 Evo ? What is different betwen them ?

Thank you! My misunderstanding; between looking at my current system report (2X) and reports here and some info on the internet, I was just wrong. Good to know, maybe I'll get a speed bump out of this.
They are almost identical other than some minor firmware differences. I would buy 960 Evo if you are looking for a Samsung. I am thinking that in a early 2015 MBPr that would work fine with the black sintech adapter.
For those worrying about how to find the green Sintech adapter, I have discovered 3 places where it still seems possible to get them:
1. Sintech's eBay store. Available there for 12.99. Unlike their main store, which ignored my messages, the ebay store promptly confirmed that the item on sale is indeed the green version. I suspect they may have reserved a batch for ebay, so as to not fall foul of the site's policies. The bad news is that i) there only seem to be about 15 left, so hurry and ii) apparently to avoid delays which might again create problems with ebay, they exclude shipping to several countries, including all of Africa, most of Asia and Latin America, and even some smaller European countries.
2. Micro SATA Cables, an online store based in Acton, MA (USA). Available there for $28.75. They also have Ebay and Amazon storefronts. They also confirmed (and proved with a photo) that their stock is indeed of the large green version.
3. Central Computers, a chain with physical stores in the S. Francisco (CA) area. Available there for $20, but only ships within the USA and the shipping rates are more expensive than the product. Although the picture illustrating the product on their website seems to be of the Chenyang adapter, the part number is Sintech's, and I again received a direct confirmation, with photo, that the item is indeed the Sintech 'large green', plus screwdrivers.
hope this helps, good luck
