It can't support recovering from the internet, important to prepare a bootable USB disk driver(M.2 PCIe has no OS system inside, it must be erased first). How to use: 1. Make sure to install the High Sierra on your old drive, so that a newer firmware is installed that can handle NVME. 2. For your old driver, please do a full backup via Time Machine. 3. Create a High Sierra Installer on a bootable USB stick. 4. Open the MacBook and disconnect the battery while switching out the drive and make sure both the adapter and new SSD sit snugly. 5. Reconnect the battery before closing the shell. 6. Insert the Installer USB stick from step 2, and press the option key while the machine starts. 7. Finally, once it's up you can now go to the disk utils to format and install the MAC OS. Notice: 2. Please insert our adapter fully into the SSD slot and you must prepare a bootable USB disk(see third point) with High Sierra to format M.2 SSD first, it can't support recovery from the internet. 3. There are many customers who can use it, so we suggest you try it again if your MAC can't detect nVME SSD. Package includes: 1 x Adapter Card 1 x Screw Set & Driver
