SSD Upgrade on Mid 2013 MacBook Air Not Working

So,

I am using a SM951 256GB M.2 SSD with a NGFF M.2 Adapter.

I have researched and found them to be compatible with my laptop, a 11" Mid 2013 MacBook Air.

The original SSD went bad, and this is a replacement more than an upgrade.

I have created a High Sierra (latest) USB installer, and upon using I can see my drive in Disk Utility.

I format it as Journaled and start the installer. I select the drive, it starts installing and says about 5 minutes.

At the 2 minute mark the screen will go black (restart I presume?) and then show the apple logo.

The progress bar below will load about 10% and then it will just boot to the USB again.

Inspecting the drive in disk utility shows that about 5GB of it is now used, but it is not bootable.

What is happening, and how do I fix it?

Can provide pictures and product links if needed...

Thanks

While you likely don’t want to hear this you’ll need to put back the original Apple SSD to diagnose if the SSD & adapter combo are bad or if in the process you damaged something.

You may want to return the products and just bite the bullet, getting the correct SSD The Ultimate Guide to Apple’s Proprietary SSDs or got with either OWC or Transcend SSD’s

The original SSD is done. Boots to question mark, doesn’t even show up in disk utility, and Apple diagnostic says there is a storage device problem.

Are you suggesting my drive is not supported?

So, the drive I am trying to use is NVME not AHCI. And if it makes a difference, I do not know if the SSD that failing was running High Sierra.

par

The new format is only to be read by Sierra or High Sierra based systems. So if you are not using the newer OS you will get into issues.

You need to use a PCIe 2.0 x2/AHCI drive. Your system can't support a PCIe 3.0/NVMe drive.

par

Then explain this: https://www.ebay.com/itm/Macbook-Air-Pro...

It uses a KXG5AZNV256G PCIe 3.0/NVMe drive.

And yes, there's more than one of them.

Magic I guess ;-}

If they support it then you'll need to talk with them.

I'm a volunteer here, I don't have any financial gain with IFIXIT or any product I point to.

If you are using an SSD and installing High Sierra, Why you format Journaled??. Try Formatting in APFS.

If you format to APFS prior to trying to install, it will not recognize the SSD. The installer handles the conversion from Journaled to APFS, and it must be in Journaled to upgrade.

when you press delete, your doing it to the partition or to the drive?if mark the option show unit or drive (can´t remember) and press delete it will delete the whole partition and make a new one.

par

APFS is VERY weird. After you format it to APFS in disk utility, there is a new "alternate" method of wiping the disk that appears in the window. I can't quite remember, but a button appeared on the left that I'd never seen before. I got worried because I needed to wipe it and the Delete button was greyed out for both the drive and the partition.

par

Delete the device, not the partition, it should create a new partition in APFS

par

...In any case. The Mac OS High Sierra Installer states that the drive must be formatted as Journaled to install.

Try this:

-First boot to your USB High Sierra drive.

- Open terminal and change the date to today by entering: date 0726021018

(this is for date/ time of: 7/26/18 at 2:10 pm ).

High Sierra wont install if the date isn't set to later than when it was released.

- Next, erase and format the drive through terminal, type: diskutil eraseDisk JHFS+ MacintoshHD disk0

This may help, I've ran into issues with high sierra and SSDs multiple times and erasing through terminal this way always works.

Next, just continue with the installer and cross your fingers that you surpass that 5 minute mark!

Great tip, and thanks but no dice. Macbook Air's are so finicky with SSD's. This one may work, but not for me. Ordered a different SSD model.
