OS X Driver for NVMe M.2 Solid State Drives Released

[DaveLloyd]

Hi all, just wanted to chime in with my experiences with this ssd...

I have been using it since the driver came out for OS X, it works perfectly for me, with sleep, shutdown etc and no kps.

I used to have the reboot after shutdown issue before i even upgraded to the 950 pro, ticking 'fix shutdown' in clover solved the issue.

One thing i did try (which i haven't seen anyone else do) was to make a fusion drive with the 950 and a 3tb hard drive. The creation of the fusion drive was successful, and i was able to copy data to it etc. I then tried to install OS X to the fusion drive, but it failed with an obscure error message. No matter what i tried i couldn't make it install successfully. In the end i settled for using the 950 as a boot drive and the 3tb for storage. This arrangement has worked perfectly.

Interestingly enough, the terminal commands for seperating the fusion drive caused a freeze and was never successful. I ended up just formatting both drives individually.

Thanks for the info @DaveLloyd. I made the difficult decision to stick with the native AHCI driver for my boot drive, but that is awesome it's working for you. Eventually I want to pick up the 950 Pro to create a Fusion Drive like you describe.

It will happen brother only a matter of time before Apple stop being arses and make a native nvme driver. Their macpro community deserve as much

I gave the new Toshiba OCZ RD400 256gb m.2 drive (RVD400-M22280-256G) without success. Without the NVMe driver it was invisible as expected.

With the ssd in my motherboard's m.2 slot the drive became visible when I installed NVMeGeneric.kext in the EFI/CLOVER/kexts/10.11 folder. During startup I would get an exception during boot about the com.Minstor driver.

I bought one of the recommended m.2 PCIe adapters but the results were the same. I also tried to install the NvmExpressDxe-64.efi in the drivers64UEFI as recommended by UNOE on post 60 - i was reviewing the steps and I am not positive I did the "BIOSblockIO" in clover so I'll give that a try and if it works update this thread.

In the end the SM951 in the m.2 slot was plug and play since the NVMe driver was already installed.

I have the OCZ RD400 512 m.2 Drive - I've tried my M.2 slot in the mother board, and with the expansion card and get the same crash every time (screen shot attached) Something to do with "nvme_identify_controller failed" . I have the NVMe kext in the 10.11 folder and i've tried with and without the NvmExpressDxe-64 in the the drivers 64 and then even manually moving the NvmExpressDxe-64 into the Drivers64UEFI folder. Nothing seems to let me boot.

My mother board is GA-Z97X-UD3H updated with the most recent bios. The RD400 shows up in the Bios just fine. and my windows 7 shows it as well.

Help ?!?

Hello dear friends

are these drivers good for the THNSN5512GVU7?

are they generic or for specific ssd?


Thank you

Since that drive looks like a Toshiba based SSD I would avoid it and buy a Samsung m.2 drives. Be aware Samsung offers both an NVMe interface and the older ACHI versions.

Hey guys,

just want to share my Experience with that kext:
I have a Samsung 951 NVMe.
Installation worked fine. Speeds are insane: 1135 read, 1984 write.

I'm just having one Problem: The shutdown/restart thing.

I just saw this cure for the shutdown/restart problem. It bares watching the result. Start here. (I'm unable to test this procedure at this time.)

After reading that, I thought it solved the Problem.
But my Hack keeps getting Kernel Panics during shutdown.

I think I'll get a normal SSD, since that bothers me a bit and there no fix in sight.

Here's an M.2 drive that has the same performance but without the shutdown/restart issue and other problems:

512GB : http://www.amazon.com/dp/B00VELDBJ6/?tag=tonymacx86com-20
256GB : http://www.amazon.com/dp/B00VELD92U/?tag=tonymacx86com-20

I bought the 256 GB version and it works great!

I was about to link the AHCI version that is natively supported in OS X.
