Besides eGPU, NVMe native support in High Sierra is a highly anticipated feature. This may not seem like much at first but for Thunderbolt 2 MacBooks (late 2013 to late 2015) that use Apple propriety PCIe SSD, this is a huge breakthrough.

Instead of paying more than $1/GB for used Apple PCIe flash storage for these Macs we can now get brand new and faster NVMe M.2 drives for less money. I found the Samsung 960 EVO NVMe M.2 drive was able to boot macOS High Sierra through the a couple months ago when I was trying to. Earlier today, I installed this same NVMe drive inside a 2015 11' MacBook Air using a 12+16pin to M.2 NGFF M-Key adapter. This adapter makes the Samsung 960 EVO physically compatible with the connector on the logic board.

High Sierra isn't a huge update to Apple's operating system, but there are still plenty of changes, big and small, for Mac users to sink their teeth into.

I was holding my breath at first boot after installing the NVMe M.2 drive. The MacBook Air was not able to boot.

I could not get to the Boot Selector screen either by holding OPTION key. After an hour testing the 12+16pin to M.2 NGFF M-Key adapter through another PCIe adapter inside my Mac Pro to verify it's working, I determined it must be something with the firmware of the MacBook Air. I proceeded to perform a clean installation of macOS High Sierra Beta 9 on the original drive so that the latest firmware for this MacBook Air can be applied. That did the trick. My mid-2015 11' MBA is now running Boot ROM version MBA71.0170.B00.

I did another clean installation of 10.13b9. This time on the Samsung 960 EVO NVMe. Here's the final results. Are you using the rather than the mid-2015 11″ MacBook Air one(Not found)?

I've also noticed that 11' Early 2015 was using a storage interface (PCIe 2.0 x2), which I suppose it can only run up to 1GB/s. How possibly you can benchmark it up to 1.4G/s on reading! In addition, my convert board (12+16pin to M.2 NGFF) merchant in China told me that Macs installed with 3rd party PCIe drive cannot normally wake up from sleep, did you encounter the same issue with High Sierra? I'm updating High Sierra and considering upgrading native PCIe drive to NVMe one for bigger capacity. I explain my experiences.

This is the result of trying on High Sierra beta 7, 8 or 9 with MacBook Pro 13 Late 2013, MacBook Pro 13 Early 2105, MacBook Pro 15 Mid 2014, MacBook Pro Mid 2015. There are two cases when using m.2 SSD which is not Apple SSD. 1 PCIe AHCI M.2 SSD ex.

How to insert a calendar in excel. MZ-HPU256 2 PCIe NVMe M.2 SSD ex. MZ-VPW256 1: AHCI SSD is the same type as Apple genuine, so it will definitely recognize it at startup (boot ), but in many case, it can not wake-up after sleep. Does nox work on mac for amazon video. Especially when you want to sleep SSD (HDD ) it is nearly hopeless. 2: NVMe SSD has no problem in wake-up after sleep, but may not recognize it at Boot. In regular Boot, it is often OK, but reboot is not recognized. Of course it can only be used with High Sierra. (But in Apple Diagnosis, even NVMe SSD can recognized normally) So I was giving up using 3rd party SSD, but since I had information that I can use it at 960 EVO, I checked again MacBook Air 13 Mid 2013 and 960 EVO 256GB with High Sierra after release. 1 was reproduced as it was.
