Maybe it’s a high Sierra thing? I’m running the latest bootrom on my machine, and I peak around the same speeds, usually around 2800, though it never stays that high for long.
 
You simply have to :
1 - download NVMeFix.kext and Lilu.kext
2 - Install both with KextBeast in /Library/Extensions

I did this with SIP disabled but you may be able to only activate the unsigned kext in "System Preferences" -> Security


I've tried under 10.13 and even if the kext did load, I didn't see any reduction in standbye mode, but I need to test in 10.14 and 10.15, 10.13 is not supposed to be supported.
Will try it and report results

I tried with both Hackintool and Kextbeast on 10.14.6 and power draw in idle is still the same, no difference. And yes the kexts are loaded, I checked.

Did I miss something?
 
Does anyone else have issues with write speed dropping dramatically (to 60MB/s) after sleep?
Once restarted it comes back to the right values (~1400MB/s)

Hi,
This is my power draw, while some basic usage - browsing. Basically it does not get lower then 119 mA. It look like NvmeFix does not work also for me.
I've got MBPro 15 Mid 2015 and Sabrent Rocket 512GB.

Hello everyone, I upgraded my computers -macbook pro mid 2015 15” from 512gb to 1tb Samsung pro970. I bought the sintech adapter (the long one) And installed it into my computer, i attached my new ssd to the adapter and the adapter to the macbook pro. I found that i dont get the best speed, and it actually really slow for it, i had tried to play with the adapter and the ssd and move it to the sided on the logicboard, i found its helping, when I did that I got speed up to 2580 write & 2250 read, but only for a short time, and than it goes back to very slow such as 1380 write & 1480 read. The reason i kept play with it is because i saw different of the speeds, but after i turn off my computer and turn back on the speed getting down again. I want to share with you the picture of my disk utility and what i did when I first installed the macos. I got to this because i think this is the reason that my ssd is too slow for an nvme ssd.
please, help me understand and guid me, what should i do the make the speed highest as possible?
And what is the reason/what i did wrong in the installation that my mac is super slow.?
my Boot ROM Version: 192.0.0.0.0
Model Identifier: MacBookPro11,5

please help me, im getting around with that issue for half a year.
buying different adapters and trying million things from kaptop tape to reset pram, format my MacBook for 3 times. nothing helped.
I really wish someone will direct me to do the right thing to get the best of it.
PLEASE HELP ME. thank🙏 !!

I have the exact same problem but with the Sabrent drive. Interesting. So it sounds like either a logic board or adapter problem.
 
Reporting on a SK hynix PCIe Gen3 x 4 PC300 NVMe
Disc Utility will see it, it format it and Mojave will install but it will not boot.
 
Hello. After much deliberation, i have decided to register an account and contribute back to the people who helped me save my mid 2014 MBP EMC 2881. My A1398 had a dead ssd represented by a folder with flashing question mark.

I read this forum and went ahead with a Toshiba XG3 256GB + Aliexpress m2 AHCI adapter. It didn't work because my macbook never updated from Yosemite (i ran Windows all the time).

I installed Yosemite back onto a thumbdrive using apple recovery, then downloaded the high sierra update from the app store. They did not let me install high sierra into an external drive citing that I was missing a firmware partition. What i had to do was to get an original apple SSD (I borrowed my sister's 2015 MBP 13" SSD) and inserted it into my macbook, so that i could install high sierra into my thumbdrive. It worked only with an original mac ssd in there.

With high sierra in, my bootrom updated from MBP112.0138.B11 to MBP112.0146.B00 on high sierra, then through the 2019-007 update to 156.0.0.0. Best of all, i didn't alter any data on my sister's apple ssd.

Afterwhich i swapped into my aliexpress adapter + XG3, and booted into my thumbdrive's high sierra instance, then noticed an invalid drive detected. I formatted it to APFS using Disk Utility and then I installed the app store Catalina update into my XG3 nvme SSD. Voila, it works!

It was tedious slowly updating my way from yosemite to catalina, but i had to do so because I understand that the critical boot rom update happens at High Sierra.

I was quite happy to get it working, given that I never used my macbook partition in my entire life and had no idea how mac works.

Anyway this test case has proven successful, so *NEXT STEP:* is to purchase a Trenscend 110s 1TB nvme and see if it works. I don't use my mac partition so I don't know what the apple side consumption is like. I like the numbers I saw on the first page power consumption table showing that the 110s has better power efficiency and comparable (if not slightly better) read/write overall speeds as compared to the 2015 MBP ssd.

I was considering the 220s but it seems to fare worse, even though it was supposed to be a newer drive.

I'll keep you guys posted on my bootcamp experience after I get the 110S SSD.

In the meantime, for bootcamp do you guys recommend APFS or HFS on my mac partition? How should i partition my ssd for optimal performance on this third party setup?
 
Anyone know why the nvmefix is not working? There’s not much help on github or the hackintosh forums.

It is difficult to understand your post.

From what I can tell - you say that running the speed test starts out fine then the speed drops? This has been reported previously in the thread and simply has to do with the speed test cache.

Can't comprehend if you think the computer is slow outside of the speed test as well or it's solely based on the test?
 
Hi,

I use Intel p660 2TB on MBPr 13 late 2013 with Sintech adapter.
On OSX I got random black screens and than macbook restarts by itself.
On Windows 10 via bootcamp I also got few bluescreen.
I did try to update fw but it is on latest version.
On windows I also did try to enable high performace power profile in control panel, it did reduce bluescreens but they still appear from time to time. they seem to be more common when macbook is running on battery.

Any idea how to fix this?

Thanks and have a nice day
 
Hi everyone,

thanks for the valuable info on this topic!
I'm about to upgrade my 2015 mbp to a Transcend 220S 1TB drive. I would like to ask if there exist an opposite adapter (gumstick to m.2) so that I can use my laptop's original drive with a cheap m.2 enclosure.

thanks!
 
Hello Everyone,

new member, first post. And I got here through web search looking for info about SSD upgrades.

Would be great if someone could take a brief moment and help me with the following:

I have an early 2015 13" Retina MacBookPro12,1 and I installed a Sabrent Rocket Nvme 4.0 M2 1TB. Installation was a breeze and I'm now running a Catalina / Linux dual boot. I'm very happy with speeds and the new found space. Only issue I'm having is bad battery drain both when active and while sleeping. For example 8 hours of sleep under battery will run a 100% battery down to 80%.

According to page 1 my model should support native Nvme hibernate. I also skimmed through the latter stages of the thread and it appears there are people who experience much better battery performance than I do.

I'm running up-to-date Catalina (10.15.2) and my bootrom version is 188.0.0.0.0.

Is there something obvious that I'm missing?

System-wide power settings:
Currently in use:
lidwake 1
autopoweroff 0
standbydelayhigh 86400
autopoweroffdelay 0
standbydelaylow 10800
standby 1
proximitywake 0
ttyskeepawake 1
hibernatemode 3
powernap 0
gpuswitch 2
hibernatefile /var/vm/sleepimage
highstandbythreshold 50
displaysleep 5
sleep 20
tcpkeepalive 1
halfdim 1
acwake 0
disksleep 10

Thanks for your time

EDIT:
Changing to hibernate to disk (hibernatemode 25) mitigated the battery drain while sleeping issue. Now there is virtually no loss. Still a bit hungrier while active but I can live with that.

Hello everyone,

Thanks to this thread I recently installed an Intel 660p in my 2015 MBPr (Macbook12,1) and I really like the added space! Battery seems good too.

However, I do experience a problem, and I am not sure if changing the SSD has caused it. Since upgrading my SSD:
  • My touchpad AND keyboard are not working when freshly booting. My mouse just hangs in the top left and my keyboard does not work to fill in my password. I have Filevault disabled because I thought this was causing it.
  • Doing a couple of restarts and a couple of SMC and NVRAM resets usually makes them work again. But sometimes I have to plug in an external mouse and keyboard and log in.
  • After logging in and my keyboard and touchpad working again, out of nowhere my touchpad stops 'clicking' (while it keeps working), and will start 'clicking' again after some time.
I already went ahead and re-installed MacOS with the recovery boot option. I think this is the same as just a clean install, right?

Anyway, does anyone have an idea what could be causing this? I never had these issues, but right after upgrading my SSD this started to happen. So, while not knowing for sure if this is caused by it, I do suspect it.

Thank you for your time and efforts. Hope to hear what you think!

Check the connections to your logic board, could be loose or slightly corroded

Thank you so much for your reply. I will do that, but before I do I am wondering: if it would be a connection, why would it work after rebooting a few times?
 
I am planning to install a 2TB NVMe ssd in my late 2013 MBP using the Sintech adaptor. I already have Catalina running on the SSD using it via a USB external enclosure. Will the MBP boot up and run using the already installed OS or will I have to reinstall everything?
 
Thank you so much for your reply. I will do that, but before I do I am wondering: if it would be a connection, why would it work after rebooting a few times?

I would suggest changing the trackpad to logicboard cable. Common problem on the 2015 retina 13" models.

About $5-6 on eBay.

First signs of a failing trackpad cable are the keyboard and trackpad not working and a reboot fixes it temporarily. A bad trackpad cable causes the keyboard not to work as well.......

Great thank you, will take a look at that and hopefully fix it!

hello, I can tell that the computer is slow as well. the highest speed I got was 2580 write, 2300 read.
I felt the difference between the speeds now and then. now I dropped down around: 1400 1300 read write.
I don't understand where is this problem came from.
according to nvme ssd it must be higher speed and Im very disappointed that im not getting the best of it, or at list the best I can get from my computer and the new nvme ssd.
im sure that something is wrong in the settings of my computer, im sure something don't let my ssd get the highest performance.
please help me.

you posted screenshots where the ssd was 85% full - maybe that has something to do with the slowdown.

i'm surprised that a 1400/1300 rw speed is in any way noticeable as slow

the answer is probably to stop running read write tests.

Do you have FileVault on? I think those of us who got 2GB/s speeds don't have FileVault on. (At least I didn't, Sabrent Rocket 1 TB on rMBP 2015 15")
 
Hi,
This is my power draw, while some basic usage - browsing. Basically it does not get lower then 119 mA. It look like NvmeFix does not work also for me.
I've got MBPro 15 Mid 2015 and Sabrent Rocket 512GB.
Can You try to use lspci to check the ASPM Value on the SSD?. Refer to my post no. 5261, 5282, pg 211-212. I switched my production machine to Sabrent and the Samsung SSD is now an external and is in use so I can't check right now.

If NVMeFix reports that APST is turned on, then APST is almost certainly on.

I suspect iStat is reporting ISDC, PSDC SMC keys, but I don't know what they exactly indicate and how they are physically measured. Rather than looking at this graph, you should compare battery life with and without the kext.

FWIW on Windows StorNVMe reports APST enable success, and I am getting approximately the same ISDC and PSDC values as on Mac. However, for my typical use case I get 30-60 min longer battery life with APST on.
