Hi! The built in SD card reader never worked on my MacBook Pro Mid 2015.
As I always had an external reader, I never cared about the problem. But now my external card reader stoped working and I need the other one to work.
Does anyone had the same problem? How did you fix it?
Apparently the thing was supposed to be ok, but I have had several sd cards (I'm a photographer) and none of it have ever been read by the built in card reader.

If it has "never worked" since 2015 I would not hold your breath. System information shows it is recognized...
SDcard readers have always been finicky at best.
Shine a light in the port and if you see debris in there, clean it out—machine shut down, non-metallic object (toothpick), soft vacuum etc and see if that makes a difference.
