I have a mid-2015 15" MBP, so I hoped for a quick and painless upgrade. Bought a 2TB ADATA SX8200 Pro, and a generic adapter (photos included). I'm on latest Catalina (10.15.6), with the OEM SSD everything wors fine. But I can't get the ADATA with adapter to be recognized. Not in Disk Utility, not in Terminal, and System Report says that "This computer doesn’t contain any NVMExpress devices.". Tried with a cloned boot disk from an external drive, from a Catalina USB install stick, and from Internet Recovery - no change. Also tried Kapton tape on the pins and on the bottom of the adapter, as well as a rubber pad - still nothing. I sincerely hope this is just a bad adapter, ordered the original Sintech from Amazon, but it'll take at least two more weeks to get here. Is it likely that the SSD itself is bad (ordered an external NVMe USB enclosure to check, as I have no access to a computer with a M.2 NVMe slot)? Could the bad adapter fry the SSD?
