Check that there is no damage, i.e., scratches on the shiny contact points or greasy coatings of any kind like food substances, dust, or mud.
Clean your SD card with a clean and soft dry cloth. Do it thoroughly, especially on the corners around the contact points. However, don’t use water or lick the fabric with saliva. The moisture can destroy it when you insert it into the device.
To avoid write protection, make sure the switch on the side is on.
The slot is usually thin and wide. To embed, make sure the contact points are facing down, and they should go in first.

After that, try inserting your SD card once again. With this method, most people can find their SD card recognized on Mac now. If not, you need other solutions.
Check if the computer's SD card reader is working properly by connecting a different external hard drive to your Mac.

If you are still wondering how the SD card works, then you are in the right place. The SD card is a nifty little device that can pack a tone of storage capacities of more than 1 TB.
With an SD card adapter used together with a microSD card, it gives you the flexibility to access files it may have from any other source.
But what does SD stand for? It stands for Secure Digital, a standard that describes non-volatile memory. Mac computers come with the SD card slot, also known as Secure Digital or Secure Digital Extended Capacity (SDXC) card slot through which you can insert your SD card.
So, there are formats and standards discussed above. Also, the SD card slot has its measures such as:
You can use these cards with adapters that conform to the specified physical standard.
All these storage media use specified file systems to store data. File systems store data in a breakdown of various clusters, depending on the type of file system.
The most known file system is the FAT32 format. It is available up to 32GB in capacity. For media that exceeds this uses the exFAT file system. Cards of smaller sizes utilize the FAT16 file system.
