So I just bought a card reader last week for my MacBook Air. It worked two days and now it won't. I've looked under about this mac and it shows up as in the usb drive, it shows up in disk utility sometimes. However, it says it can't be mounted. I have tried everything!! Any help?
MacBook Air, macOS High Sierra (10.13)
There are several problem points: 1) defective card reader, 2) defective card(s), 3) card(s) okay but there's file damage preventing them from being read.
The best strategy is to try the reader and cards with another computer. For what it is worth, I learned years ago that buying a cheap card reader was a false economy and after purchasing a more expensive name brand card reader I seldom had problems again.

Please excuse the straight forward or blunt response. I have a MacBook Air circa 2014-2015. I have five SD cards beside me from SanDisk and PNY ranging from 256MB to 16GB. The Air's do not have optical drives and these aluminum enclosed MacBook's make it quite impossible to change out a card reader that's soldered to the PCIe bus deep within. And, it ought not have to purchase an external card reader after paying Apple for one already. Apple, maker of the newest human appendages, a company that just posted 4th QTR revenues of $52.6 billion, cannot come up with a fix for card readers in machines.
What is the fix, it's not the card, it's not the file system on the card, the card reader is clean, inspected and everything is good except the OS in this $1000 machine cannot recognize it's own hardware. I find it ironic that Apple devices can recognize my fingerprints and my identity via facial recognition, but this device cannot recognize a card reader attached to it's on PCIe bus.
To Apple Executive: Fix the problems or those 2025 will look more like 1985. Lose sight of quality, lose sight of the basics and lose your customer base.
What is the fix to these malfunctioning card readers and or their associated PCIe bus system?
