M2 SSD upgrade not recognized

Hi everyone!

I'm trying to install an M.2 SSD on my Mac mini, in addition to its 1TB HDD.

I have purchased this adapter: https://pt.aliexpress.com/item/400016101...

And installed it myself. I heard and felt a “click” when plugging it on the Mac Mini, which I thought might be normal.

After rebooting the Mac mini, “ > System information” does not show the NVMe drive, neither does PCI or anything else. There's only the default HDD that comes with the system, but my SSD doesn't show. Disk Utility can't see it either.

The SSD is a WD Green 240GB M.2 2280 SATA III 6Gbps.

I have a gaming PC which recognizes the SSD and is able to format it. I was also able to install Windows on this SSD. Can anyone help me? Thank you!

Update: Apparently the adapter I purchased only works with M-key SSDs. My SSD is a B+M key or something like that. :( I wasn't planning on purchasing another SSD…

Your system uses PCIe/NVMe not mSATA!

Review this guide on the different custom blade SSD’s Apple has used in their systems The Ultimate Guide to Apple’s Proprietary SSDs

I personally don’t recommend using these adapters and M.2 SSD’s as there have been too many failures.

I recommend sticking with the Apple SSD’s, or using either one of the SSD’s which have been fully reversed engineered from Apples so they work correctly OWC Aura Pro X2 or Transcend JetDrive 850 using Hard Drive Carrier w/SSD Flex Cable, Apple P/N 076-00040
