Chosen Solution
Hi, I have just bought a new SSD for my Macbook Air 2015. I mounted the harddrive successfully in the computer (following the ifixit guide on youtube) and started it via Internet Recovery. At this time, in disk utility, I could see the hard drive at 480 gb. I erased it to format it into GUID and Mac OS Extented. I started the download of Big Sur, bur after a while it gave me an error, telling me that it failed to download. The only thing to do was to restart the internet recovery. Now, however, I can no longer see the drive in disk utility, and there is no place where I can install the OS. I can’t see the disk in terminal using “diskutil list” either. I can onky see “OS X Base System” at 2GB. It’s impossible that there s a hardware problem, but I can’t find a way to fix this. Please help. I’m going slightly mad. I need to fix the computer asap as I need it for work. Here is what I see: Disk Utility with “get info” on the side: https://ibb.co/cT4ZYmL Terminal “diskutil list” https://ibb.co/DVdLmR7 OS X installer: https://ibb.co/7KdQnSM I have googled for hours with no luck. A thousand hugs to the person helping me to find the solution! Thanks!
Confusion and confusion! In an effort to simplify their web page they grouped the MacBook Air’s into a single line item: Mid 2013 –2017 MacBook Air 6,2 / 7,2 - JetDrive 850 (NVMe) or JetDrive 820 (AHCI) Sadly there is a bit of differences across these! Mid 2013 & Early 2014 - 5.0 GT/s PCIe x2 uses PCIe/AHCI drive Early 2015 & 2017 - 8.0 GT/s PCIe x4 uses PCIe/NVMe drive
So what does that mean here?? You’ll need to return the drive as its not the correct one for your system. You’ll need to get the NVMe drive.
