Why doesn’t your SD card show up on Mac?
There are many possible causes for this issue and some can result in Mac not reading the SD card.
- You use the SD card in the wrong way. When inserting the card into a card slot, make sure that the metal contacts face down and point toward the card reader. If not, you won’t see your card on the Mac and the slot might be damaged as well.
- Your card reader is out of date. Manufacturers design new SD cards with more advanced features all the time. It’s likely your old card reader can’t keep up with the latest SD card and needs a replacement.
- The SD card format is not compatible with the card reader. Different card readers have different tech specifications. So, make sure the card reader conforms with the SD card’s transfer rate, read-write speed, dimension, type, storage capacity, etc.
- Other reasons. For example, virus infection, macOS system error, an SD card corruption can all lead your SD card invisible on the computer.
