RISOLTO: Trying in install a new SSD - MacBook Air 13" Early 2015

Trying in install a new SSD

Hi,

I have an MacBook Air 13" Early 2015, A1466 EMC2925

I installed a PCIe Gen3 x 4 / 3D NAND Flash for Mac SSD (6+12Pin), but it is not seen.

What did I wrong?

I have updated Mojave on the original drive before (firmware 489....), then replaced this with the new SSD.

When booting in Recoverymode, then use the diskutil, it is NOT listed.

SMC reset and NVRAM reset also done.

I have no idea what to do .... maybe you can help me.

Thx

Why not install OSX Monterey?

You really need a bootable external drive with the correct macOS which supports NVMe drives.

Using a second Mac download the macOS installer from here Update macOS on Mac and from here How to download and install macOS.

Personally I like to create a bootable USB thumb drive. Make sure you reformat the thumb drive to GUID with a Journaled File System. Then copy the OS installer onto the drive and follow this Create a bootable installer for macOS

Now using this drive boot up your system accessing its copy of Disk Utility do you see the drive now?

Thx Dan, this helped a lot.

I didnt know, that in the beginning of the installtion of a new MacOS you reach the diskutil too. At this point the drive is listed :-)

cheers
