Hi all, I wonder if anyone can help? I have both macbook pro 2015 13" and 2014 13". I am trying to get NVMe drives to work in both but so far I have had little success. neither macbook pro will see the drives at all, nothing in NVMe section, nothing in PCI section and nothing anywhere else. Also they dont appear in Linux either. Im using the green adapters not sintech. I have checked all connections on the adapters with a meter and all show ok and I have tried the Kapton tape thing too. The drives are Samsung PM951 and PM961. I have an NVMe card in my old 2008 mac pro, this will see both drives in 10.11.6 El Capitan with kext installed and I have formatted both to Apple format. I can read and write to them without issue. When I transfer them to the macbook pros with adapters they are just not seen. Im using High Sierra and my bootrom in 2015 one is MBP 121.0175.B00.
I've also tried the solder jump on the adapters. Nothing works. I have ordered a couple of sintech adapters but these will take forever to arrive as I live in the middle east where the postal system takes forever.
My apple ssd works fine in both laptops but it is NGFF not NVMe so the laptop sockets are fine. I can only think that the adapters are at fault but they do seem to be ok when I do a continuity test.
I did notice however that the power enable seems to be controlled by the clock enable line and the clock enable to the mac is grounded and so permanently enabled. also the OOB lines are ignored.
I've run out of ideas any suggestions anyone? Please.

well, guys, I'm giving up ....

After two days of battle with my macbook pro 13 retina late 2013, a green large synthech adapter and a 1tb Toshiba XG3 ... I came to the conclusion that the whole situation is too unstable and not worth the effort ..
Initially I thought that the Toshiba was defective, but working on It I was able to see it in Ubuntu and check the 4k formatting and even install ubuntu on it ... all working OK.
BUT ... BUT ... there no way of making the disk visible to osx install.
Of course my machine has high sierra, the right bootrom and all that ... but while linux sees it perfectly (I even managed to check the drive with an OCZ ssd utility) on the OSX side there's no way to make it appear. I tried everything and cheched all forums and suggestions ... nothing.
The drive is OK, the firmware of ssd updated, all is fine ... but the mac refuses it. Maybe 1TB is too large for it ...
It's clear it's something in the firmware.
Now, after two days wasted in tests ... I came to the conclusion that I'd better spend my time in some work, earn some money, and pay the premium price for an Apple SSD ...

Maybe you haven't just made all the partitions visible in the installer menu? Since the drive is factory formatted disk utility has jus no partition to display, and in high sierra you have to change the view layout to discover phisical devices and not just partitions in the left column

Have already installed xg3 OCZ-branded drives in three Macs, and no issues till there. Since 4k fortmat discovery it has been the most compatible nvme drive IMHO

Open terminal and type diskutil list <enter> see if it shows up in the list of drives.

Hello guys! I just want to share my experience so far. I have an late 2013 13" MBP with an Samsung SM951 256GB and this Adapter:
https://www.amazon.de/TS-Trade-16pi...coding=UTF8&psc=1&refRID=9WQC75D9XFP7EEBT6PAE

Deep Sleep seems not to work properly; as I wanted to turn it on after it being closed in the night, my macbook did simply a restart..
Also it takes like 20s for the Apple Logo to show.
FileVault is activated.

I already did all these tests. Created partitions of different types, format the drive, even try to format it at 512 instead of 4096 ... did all the tricks to disk utility to show all devices, tried terminal and disk utility list ... nothing.

I even managed to install high sierra also on an external drive, boot from it with the nvme disk installed ... nothing, never appeared in any situation.

Are we sure that with all recent updates from Apple ... they don’t have introduced some check that excludes some type of drives?
At this point I really don’t know what to do.

As you can access the drive with ubuntu then it should also appear in the pci window of system report in mac os as an NVMe controller. If so does it say driver loaded yes or no, if no then Apple kext is not loading.

As I wrote before with ubuntu installed the drive shows ORANGE at boot, and boots to ubuntu properly.
This means that:
- the drive and adapter are OK
- the drive is strangely recognised as EXTERNAL
If now I boot from an external USB with High Sierra first of all I have problems (sometimes it goes, sometimes it shows a message that something went wrong and reboots) and when I finally get to the OS there's no way to see any name drive. The drive is there but nothing shows it (system info, terminal commands etc...)
This leads me to think that the drive is actually refused or not initialised by OS X. Moreover, although temperature and power are ok (60 degree celsius and 6W max) there's something that makes the whole computer reboot at random ... and it's OSX , since with ubuntu everything is fine.

I believe this situation cannot be rescued .... unless there's some change in bootrom... some update ... and then who knows what will happen about reliability, reboots, sleeps, huge transfers ... no way, I stop here and go back to my original Apple SSD.

Hi,
really sorry for your loss of time, your problem seems very strange...

I can tell you I never had any problem with Toshiba drives and, in september, I put a new Toshiba 1TB XG3 and gave it to one of my employee which installed it with a large green Sintech adapter.
It has been a simple, free and trouble-free upgrade and my employee has been running its MBP retina 13" with Sierra for now more than 6 months with an intensive use of Aperture, daily use, without any issue...
The 1TB Toshiba SSD costed me less than 350€, so it was worth it...

The fact that it works under Linux and not in macOS is strange tought...
Is the SSD new ? What is its firmware revision ? (or can you give an output of the smartctl command)
Did you try to write zeros to it under linux to delete any existing partition ?
Have you tried both 10.13 in 512 of 4k bloc size, and 10.12 in 4K bloc size ?

Hi,
In all my tests, I can tell you that Sintech adapters work with all SSD, but other M.2 adapters (chenyang) don't work well with Samsung drives, especially connexion is lost at reboot, only cold boot work...
If I were you I would wait for the Sintech adapters... Also give me a personnal mail if you want me to send you one from france, it may (but may not) come faster than from China ?

Hi Gilles,
I know my situation is strange ....
The drive is almost new, less than 100 hours of use, 100% health as displayed by smartctl under Linux ...
The firmware is the latest according to the Ocz ssd utility under Linux (although I believe there’s a newest one, number ending in ...4105, that I found as a Dell update ... but I’m unable to install it because the installer is only windows and I don’t have a windows machine with nvme slot ....)
After two days of trials without ever seeing any change in visibility ... I don’t know what to do.

I’m thinking about the orange EFI drive that is displayed after installing ubuntu on it ... looks like the Mac sees a drive with a bootable os and is capable of booting it ...
But despite trying to format the drive in any possible configuration ... it was never visible and usable by diskutils or by disk utility ... and the fact that even booting high Sierra from external usb the ssd is never visible ... really don’t know what to do.

Again, sorry for your problem...

Toshiba drives being oem drives (retail being sold with OCZ brand), some may have a specific firmware for a specific manufacturer...
Every toshiba drive I tested worked directly but there may a version which has specific problems, can you post your firmware version ?

I find your problem interesting and would be ok to send you a tested drive to clear things out...

As a sidenote the firmware update executable provided by Dell may check for Dell hardware and only work on a Dell laptop (not sure, but it is the case for Lenovo firmware upgrade utility...).

After two days of trials without ever seeing any change in visibility ... I don’t know what to do.

I’m thinking about the orange EFI drive that is displayed after installing ubuntu on it ... looks like the Mac sees a drive with a bootable os and is capable of booting it ...

I'm not in front of a computer at this time but If I remember correctly, with every 2013-2014 macs, the boot menu (alt key pressed) normally presents NVMe boot drive with an orange icon (as it is the case with Raid PCIe storage, SAS drives etc.).
Once booted on macOS they are properly recognized as internal, non ejectable drives.
So this part is normal.

But despite trying to format the drive in any possible configuration ... it was never visible and usable by diskutils or by disk utility ... and the fact that even booting high Sierra from external usb the ssd is never visible ... really don’t know what to do.

I would really try to write zeros to your disk (only on the first MB would be enough), there may be a partition table that macOS doesn't like...
Also confirm that you have a clean macOS with no patch and you may clear/delete the kextcache of your external drive (with Onyx f.e)

Also you can try a SMC and/or Pram reset, it won't hurt...

Has anyone had experience with MyDigitalDiscount products generally, and specifically the MyDigitalSSD 1TB SBX in the scenario presented in this thread? I would like to upgrade the drive in my MBP 13" mid-2014 to a 1TB drive. My interest is capacity (1TB) and reliability; I am satisfied with the performance of the drive it came with and don't need any faster, and am probably considered a low-intensity user. In the 512 GB size, there might be a $40 spread between the cheapest SSD and the Samsung 960, in which I would go with the Samsung, but in the 1TB size, it seems there the MyDigitalSSD is a good $100+ cheaper ($320-$340) then anything else. But is it good quality and will it work? Thanks.

- I tried SMC and Pram resets several times, no change
- I changed several times the partition table on the disk, even with gParted while booting from Ubuntu ... I even tried to create a GPT partition scheme and a unique Mac partition formatted in hfs+ ... no change
- I have clean high Sierra installed on the original drive just before swapping the disks, with all updates up to the latest shown by App Store (the one related to problems with some characters in texts ...)
- for more advanced tests like clear kextcache (?) ... well, I need some guide, I’m not so expert on Mac procedures (although I have 35 years experience as a computer consultant... so I know something about computers, drivers and all that...

== I checked the firmware version: 57DA4009 .... I know that exists the 57DA4105 but I don't know if it can be installed (only DELL windows installer found ..)

Thank you!

Hello all
Adapter: green Sintech, with kapton tape added on both sides

Results:
- I found the final position of the SSD to be a little weird. It seems to rest at an slight angle, the adapter side being a bit higher than the screwed-down side. Also, the top of the adapter seemed quite a bit higher than the surrounding circuitry, I'm concerned that it might have become squeezed against the external casing when that was screwed back on, but like I said, I have experienced no problems. I did kapton-tape it over the top, so insulation is not a problem, but I'm concerned with eventual knocks and bumps.

Groobert
I also got it working :) Toshiba XG3 1TB, with green sintech adapter.

I found the final position also a little weird. When insered in the green Sintech adapter, the SSD is rested at an angle. Is this with all green adapters? See the picture attached. I've put kapton tape around the adapter. The black adapter had no angle with SSD inserted, but didn't work. Didn't see the ssd as a disk on the Mbp with that one.

Furthermore, I had a small piece of rubber placed under the adapter, as gilles_polysoft suggested in one of his posts, but removed it in the end. With the adapter, the new NVME disk sticks out, and makes it necessary to put some pressure on the lid of the Mbp to make it possible to tighten the screws. With rubber resulted in lower read and write speeds. The positioning and connection of adapter and SSD related to the performance is rather delicate. Without the rubber, the speeds were far better.

Any tips how to make the connection safe and robust? Would the new longer adapter be any better?

Hello, maybe you could use Winebottle to open an .exe program. I don't know if an "installation" of such a specific thing could work but would be worth a try I guess.

So you partitioned the drive in Unbuntu, but did you boot into OSX with a High Sierra USB boot drive? I had the same issue, I tried to boot into OSX using Internet Recovery and it wouldn't see my drive. I had to make a High Sierra boot USB inside OSX and boot into recovery using that for it to see the drive.

Sure, I booted from High Sierra USB boot drive and from USB installation key, same behaviour: nothing, the ssd dosn't exist.
Today I even tried to copy the EFI partition to the SSD from the USB High Sierra install key ... nothing.
I can see the drive only in ubuntu.

There seems to be a much more recent 57DC4102 firmware.. unfortunately you need a Dell computer to apply it.
Send me a personal mail I may find a workaround.

Hi,

I had done a lot of tests with Bootcamp recently, on a late 2013 MBPr with either an AHCI original Apple SSD, a NVMe Apple SSD, and a Toshiba XG5 with the Sintech adapter (both green and long black one).
To resume my test, so far, Bootcamp installs and work reliabely in every case.

In every tests I did install Windows 8.1 Pro or Windows 10 Fall Creators update (1709).
I did try both install methods :
- install first macOS, and then use the Bootcamp Assistant to make the partition, build the usb install key and install windows with this specific USB key.
- create a "regular" windows usb install key on a windows computer (or VM) with the windows usb media tool.
Then manually install windows on the SSD (erasing it all) like a regular PC. Then manually install the Bootcamp drivers v.7.

Every time, it did work, and I tested the computer for hours. I even tried deep sleep which works the way it works with windows : the hibernation shuts completely the computer (keyboard is inactivated) and I have to power it on with power button to wake it, it chimes and restore properly from the hibernation file.

So I haven't yet been able yet to find what combinaison doesn't work.

I remember having tested bootcamp with Sintech adapters and NVMe drives a few months ago and having problems (bsod) a while after the installation. It was with a 960 Evo.

I also have read a lot of comments of people having BSOD with Bootcamp on mac with regular Apple AHCI ssd..

So, at this point, I can strongly say that windows 10 1709 with BootCamp, properly installed with the Bootcamp drivers v7, work perfectly on a mac
with Sintech adapter and NVMe toshiba ssd.

I have yet some work to do to try other combinaisons and find which combinaison doesn't work. I believe it could be one of those :
- windows 10 with Bootcamp drivers v5 or v6
- maybe bootcamp with samsung SSDs

Samsung has a specific nvme driver that I should give a try, I'll especially will try to install Win 10 with or without the samsung driver.

I'll you know...
[doublepost=1521381429][/doublepost]
Hi Arnaud,

the long black Sintech adapter is exactly the same as the green one... Please check my results with BootCamp just below !

Hey everyone, I just did this surgery to my early 2014 MBA 11" and thought I'd share my experiences with this after a couple days.

I got a Samsung 960 Evo (250GB) and the long, black Sintech adapter. I also applied Kapton tape to the pins and a few mm on each side. So far, I've had no heating issues, I had to set:

hibernatemode 3 (which is apparently default) standby 0 autopoweroff 0 in pmset

when I didn't do that, after maybe a half hour my MBA would reboot while in sleep mode and suck A LOT of power. This resolved that issue and after 7 hours of being in sleep mode my macbook stayed at 100%

But, the downside right now is my battery life SUCKS. I think I'll be getting 4, maybe 5 hours of battery life which is downright pathetic. This laptop sat unused for about a year so I kinda forget what battery life it had in the recent past, so not sure if it's the new SSD really sucking the juice or if it's just an aging laptop at this point

I'd say 6-7h depending on usage, but it's still far less then before the upgrade (ca.10hrs) :/
Worth it anyway.

I'd like to point something out about the battery life. Download CoconutBatteryApp and record the battery draw when idle and at load, both using an Apple AHCI SSD and the nvme ssd. You will find that the power draw when using nvme ssd is higher by a constant value, which suggests that APST or ASPM is not enabled in macOS, buying a SSD with lower idle power draw is not going have any impact on battery life with the current nvme kext because it's not even in the idle power state!

Once again, I am using the Chenyang N-941 small adapter on an Early 2015 Macbook Air 13.3", with 960 EVO 250GB, 2B6QCXP7 firmware, 100 cycles or so on battery (forgot), 92% of original capacity according to CoconutBatteryApp. I am able to get x4 link width with 1.5GB/s + sequential reads and writes as stated in my earlier posts without using kapton tape. SSD is lost on reboot and wake from suspend with the default hibernatemode 3. hibernatemode 25 works.

For me, in 10.13.3 (i don't have the screenshot, but please believe me), I see between 8 and 9 W completely idle with no windows open. The maximum possible battery life is 54.4Wh / 8.5W = 6.4 hours, which is completely logical with my previous post.
cah8429 has a MBA 11", which has only 38Wh battery, / 8W, let's even give it -0.5W because of the smaller screen, = 4.75 hours only!!
With the MBP 13" 2013 and above, you can definitely expect longer battery life because the battery is so much bigger in proportion to the MBA 13"; it's 74.9Wh, even with 10W draw you can have at least 7 hours, if not more. Apple's strategy to achieve long battery life, especially with the MBA is by betting on very low idle power draw, which it can't do with the retina 13” screen without stuffing a huge battery in there!

I decided to bootcamp windows 10 because I need the battery life and mobility. I did a fresh install like Jules, first using macOS recovery partition to erase the whole SSD, then using Bootcamp Assistant with a 1703 ISO. I think the main reason it went smoothly for me is because 2015 and above Macs are able to automatically load the drivers somehow from within Bootcamp Assistant into a temporary partition; I didn't need to use a USB drive at all to complete the installation! https://support.apple.com/en-us/HT201468

I upgraded to 1709 using Windows Update and wanted more space in Windows so I cloned the windows partition with Winclone, wiped and reinstalled everything again (lol) and this time allocated 22GB to 10.13.3, and 210GB to windows. I was able to restore the 1709 image. I'm still with the windows drivers for better battery life, because http://www.tomshardware.com/reviews/notebook-battery-life-storage,5152-3.html Some reviews show the 960 EVO getting better performance albeit with 80 minutes less battery life, which would probably be more obvious on the MBA because they tested with a gaming laptop.

Hibernate and Sleep works and is very stable, I've tried hibernating with VMWare player running, hibernating in power saver mode, rapidly closing and opening the lid while it's entering sleep, you name it, no BSODs this week so far, with the small Chenyang adapter. According to HWInfo I get 6.2W power draw on medium usage w/ battery saver on, or between 8 and 9 hours, keyboard backlight off. With less tabs and no Google Chrome 10 hours is definitely possible. I'm sticking with win10 till the idle power issue is fixed in macOS, if ever. I would encourage others to try bootcamp win10 1703 or 1709 on 2015 MBP or MBA with other drives to see what other combinations work.

Hi,
really sorry for your loss of time, your problem seems very strange...

I can tell you I never had any problem with Toshiba drives and, in september, I put a new Toshiba 1TB XG3 and gave it to one of my employee which installed it with a large green Sintech adapter.
It has been a simple, free and trouble-free upgrade and my employee has been running its MBP retina 13" with Sierra for now more than 6 months with an intensive use of Aperture, daily use, without any issue...
The 1TB Toshiba SSD costed me less than 350€, so it was worth it...

The fact that it works under Linux and not in macOS is strange tought...
Is the SSD new ? What is its firmware revision ? (or can you give an output of the smartctl command)
Did you try to write zeros to it under linux to delete any existing partition ?
Have you tried both 10.13 in 512 of 4k bloc size, and 10.12 in 4K bloc size ?

Hi,
In all my tests, I can tell you that Sintech adapters work with all SSD, but other M.2 adapters (chenyang) don't work well with Samsung drives, especially connexion is lost at reboot, only cold boot work...
If I were you I would wait for the Sintech adapters... Also give me a personnal mail if you want me to send you one from france, it may (but may not) come faster than from China ?
Hi, thanks for the offer but the sintech ones are on their way and I have a tracking number so they should hopefully arrive in the next 2 weeks or so. The adapters that I have at the moment are identical to the Chenyang ones but without the name on them and are generic Chinese ones. I do suspect that this is where the problem lies especially as Im using Samsung drives.
As I said before, I have an old 2008 Mac pro with a PCIe card installed which will take an M.2 drive, Its running El Capitan and sees the drives perfectly as NVMe controllers in the PCI section of the profiler. I installed a 3rd party kext on this machine and the drives show up as external drives in Disk utility. I have formatted them to mac format ready for installation but with the Chenyang type adapters they simply don't appear on the Macbook pros anywhere at all. If I boot the Macbook pros to Ubuntu they don't show there either which leads me to believe it is definitely a hardware issue. I have now resorted to waiting for the Sintech adapters.

... power draw when using nvme ssd is higher by a constant value, which suggests that APST or ASPM is not enabled in macOS, buying a SSD with lower idle power draw is not going have any impact on battery life with the current nvme kext because it's not even in the idle power state!

Is there any way to enable APST/ASPM with nvme?

EDIT: ah I see it is in the kext, so probably not?

Hi, I would like to ask if this will work on macbook air 2015 without any issues on samsung 960 evo?


hi guys.
so a part from the sintech black long adapter, which is the best Nvme brand to avoid issues?
if I read right, the KINGSTON SKC1000 is the best choice, right?
-can be used with Sierra
-no restart issues
-no boot camp issues
-no sleep issues
-good overall performance (not great as 960 pro obviously)

What macbook to you have ? I personnally own a macbook pro 13 inch 2015.
I've been using a Kingston KC100 for Sierra compatibility. Initially an issue (sleep and restart) due to the black thin adapter ; resolved by using a large green V2 adapter. This hiccup won't happen with the new huge long black adapter.
I haven't got enough time to try bootcamp (have to look for my wi10 serial number), but it should work flawlessly.
