My Macbook Air 2014 is stuck in an infinite boot loop because the SSD is not registering I wiped my Macbook Air 2014 and reinstalled Catalina. I sold it to a guy on swappa who returned it saying it was in an infinite boot loop. I thought that I would be able to easily fix this. But when I got the MBA back, I immediately went into recovery mode and tried to reinstall macOS. A quick trip to the disk utility made me realise that the ssd is not registering. I would appreciate anyone's help with this.Could I potentially boot from a usb?
If the SSD is not showing up in Disk Utility then it is likely that the SSD has failed or the hardware that supports the SSD has failed. The failure is likely coincidental to the OS reinstall and sale, but it can't be ruled out that the purchaser did something to the Mac. What that might be I couldn't tell you.
Realistically the only way to diagnose this is to open it up, preferably by a certified Mac tech, and see what is going on.
You are probably looking at having to replace the SSD (I think this Mac has a removable SSD) in your Mac.
