Hello,Thanks! So the only problem remaining is the laptop can't be in sleep mode otherwise should be stable for daily use.
Hello to all,
a little update here.
So I tried to put a genuine Apple NVMe SSD (SM2048L) in my 13", late 2013 rMBP, under El Capitan (10.11.6).
After this night sleeping on battery, it had exactly the same behaviour on wake up : it did not properly wake up from sleep. Display stayed black, and after a while (3s) the mac did chimie and made a cold start.
Sip was disabled yesterday evening before sleep, this setting has been lost at restart this morning.
The SSD being a genuine Apple SSD from a 2017 iMac, the issue here is definitely not with tiers SSD nor with the sintech adapter. It is with NVMe SSD (being it Apple or other brand), and maybe the SMC is involved...
Also, I did checked the console log and saw en error code which is quite common with 2013 MacBook air-MacBook Pro :
10/10/2017 07:55:07,000 kernel[0]: Sleep failure code 0x00000000 0x1f006c00
It seems we could fix the problem with settings like "autopoweroff 0" or "standby 0".
Will try that...
[EDIT] I set the standby delay to 60s (with "sudo pmset stanbydelay 60").
It makes the problem occur after a minute of sleep... Ok this is a clue...
So I tried to test all combinations with smalls standby and autopoweroff delays.
Here are the results :

It seems clear that, in fact, true hibernation doesn't work on NVMe SSD (this is, again, with a genuine Apple SM2048L NVMe SSD).
So, unless other findings, solution would be to stay away from hibernatemode 25, and set "standby" to 0 with the command "sudo pmset -a standby 0"

Hello,More questions!
1 Is 4k formatting for WD Black a must or would it work without as I'm not good with creating bootable usb and using linux terminal commands. Mind post the link to the procedures?
You may install it with macports, fink or homebrew...2. Is it possible to format 4k within some Mac applications or terminal or not possible has to be done with Linux/PC?. Thanks!
Hello,
4k formatting is absolutely not mandatory. It is only necessary it you want to stay under Sierra - 10.12 (which only natively knows to work with 4K NVMe ssds).
If you are ok with High Sierra (10.13), which is able to handle 512B formatted NVMe SSDs so you don't have to use linux at all...
I'll try to make a tuto, yes !
You may install it with macports, fink or homebrew...
but is it really more simple that writing an iso of, let's say, xubuntu, to an USB key ?
I remember there were some issues on 2013-14 MacBook Pros and AHCI PCIe SSDs like SM951 or Lite-on.Amazing results, do you then mean that NON NVMe ssd's would not incur this issue on the 2013~14 macbooks then? Such as the SM951?
looks like the same issue we have with SM961 ...
Hello,
I installed a Kingston KC4000 480G on my MacBook Pro 15 Retina (Late 2013).
The disk is visible and usable on OSX High Sierra (installed on an external drive), or even on Ubuntu live USB. It works great and very fast.
But the Bootrom does not see the disk during boot. I tried going into recovery mode to disable SIP, but I end up into the external drive Recovery. Disabling SIP from there doesn't change a thing.
Than I tried to disable SIP from Net Recovery, which has Mavericks version and... the 'csrutil' tool is not present there
Almost... The first step is to update the Bootrom. It is mandatory.So with a 2015 retina Macbook Pro (13" or 15"), MacOS 10.13, a 512GB WD Black, and a Sintech adapter is it basically plug and play? Just get MacOS 10.13 on a USB, pop in the WD black into the Macbook with the adapter, and install?
The kapton tape (or any insulating tape) is a really simple precaution, it doesn't cost anything (I put katpon tape but it can be any insulating tape).Do I need to worry about the kapton tape or anything like that? If it is that easy I'll probably look into doing this.
After a while I will upgrade, for sure, from the included Apple AHCI SSD to a NVMe non-Apple SSD :
1) As I would like to avoid any issue/tweek with sleep mode, which SSD would you advice for my 13inch 2015 MBP ? Is the easily available Samsung 960EVO would a good choice regarding the 4K/512 formatting block size ?
2) Regarding performance to max out the PCIe 2.0 4x of my 13inch MPB I think the Samsung is already good at 512GB. (the 1TB would be too bottlenecked by the PCIe). Do you agree?
3) what about 4K/512 ? what are the advantages ? and in term of performance ?
4) do I need to look for buying a WD black or a Toshiba drive ?

To sum it up : Do you concur with my reading of the thread that Samsung EVO would be the better choice for a 13inch Macbook PRO 2015 ?
Hello,
There is absolutely no need at all to disable SIP in order to boot on NVMe drives, it doesn't change anything.
In all my tests (with MBPr 13" late 2013, MBPr 13" early 2015, MBPr 115" mid 2015, MBA 13" early 2015 and 2017), I never had to disable SIP to make the machine boot on NVMe drives (be it Apple NVMe drive or tiers drives).
The new bootrom doesn't produce a beep sound during startup for example.
sudo nvram BootAudio=%0
My 2014 rMBP w/ a WD Black is at the Apple Store for an unrelated repair. I spoke with the Apple Store today: the repair was completed, yet they waited authorization for an additional repair after diagnosing a "Failing drive". I declined the $475 repair.
Fortunately, no conflict with Apple regarding my NVMe substitution. Resuming tests when the MBP returns.
aww 800MB for the read/write, is it the NVME version or AHCI version? that's so bad if i compared it with my original macbook pro SSD's with read >1000Mb/s and write >600Mb/s. because i'm considering to buy that SM951 NVME hope that i got significant improve from that ssd, but after looking at your post make me don't want to buy SM951It's just an NVRAM setting, you can bring back the startup sound by issuing this command in Terminal:
Code:sudo nvram BootAudio=%0
I've been running with the Sintech adapter and a 256 GB Samsung SM951 on a Late 2013 rMBP 13-inch for the past several months (tried a Micro SATA Cables version but it was junk, didn't work OOTB) with no Kapton tape or shielding, but it's been fine for me.
Will try ordering a 500 GB 960 EVO and some Kapton as I'm running out of space trying to run Linux and Mac OS VMs (Parallels Lite from the App Store will run older OS Xs in a VM.)
I've given up on getting a 512 GB SM 951 because the prices on eBay all suck (average above $350 for a 'new' unit) compared to getting a 500 GB 960 EVO for only $240 or so.
One thing I noted about the SM951 was it was initially kinda crashy, but I enjoyed a 1300 MB read in Blackmagic speed disk test; then after I did a PRAM reset and some other things it stabilized to the point I no longer have random crashes but now I only do 800 MB read/write?!
Perhaps the SM951 doesn't need the shielding because of the lower voltage draw?

AHCI version. But who knows, I just had my logic board swapped out by Apple so maybe my LB is bad, or the Sintech adapter is failing. Will know once I get the 960 EVO installed, that should boost me to 1600 MB/s from what I gather.
