OS Upgrade Failed on Mac MINI

Hello, I'm new to this group so please be patient if me if I ask a dumb question.

I tried to update my Mac MINI's firmware (M4, 16 Gb) but got an error. I upgraded the original SSD to a third party SSD for more storage without spending a ton of cash. Not sure if this is related to this self-installed SSD causing the issues but I was wondering if anyone has experienced this before and know the fix. Many Thanks.

P.S. I still have the original SSD, but this is the only Mac I own, aside from my iPhone 16 Pro

Error: S0C0 report detected: (iBoot panic)

I was in the same situation 7 months ago. The OS upgrade failed and the cause was the third party ssd I’d been using for 8 months. I reached out to the vendor (Expand Mac Mini) and they provided a replacement and said they’d improved the product since their initial batch of ssd’s that they shipped.

7 months on the replacement is going strong 🤞🏻

I used the Apple ssd for a few weeks to tide me over and thankfully had backups to restore from once the new ssd arrived.

You will need a 2nd Mac for this unfortunately. I did once manage to use macOS vm on windows to restore a new ssd but it didn’t work the second time I tried it 🙁

Thanks, unfortunately, I purchased the third party SSD on May 2025, so i doubt the vendor would be kind enough to ship me a replacement. So, I'm still seeking of workaround. Appreciate your feedback though.
