Notice:
1. You are kindly reminded that macOS failed on resume from hibernating with some NVME SSDs of some brands. Have to turn off laptop all the time instead of close the lid and go.
2. Please insert our adapter fully into SSD slot and you must prepare bootable USB disk(see third point) with High Sierra to format M.2 SSD first, it can't support recover from internet.
3.  There are many customers can use it, so we suggest you to try it again if your MAC can't detect nVME SSD.
