If it is your first time experiencing your SD card not showing up on your Mac, you are probably panic-stricken. My advice, relax and read on.

The SD card errors can result from minor factors, such as dust, any other substance coating the contact points, or imperfect insertion into the slot. These are usually the first areas to address before you even get worried.

There are also other causes surrounding the issue of your SD card not showing up on Mac. How can we fix this issue? Let’s together find the solutions.

First. Check and Open SD Card on Mac

So, you have your SD card at hand, and you are stuck as the SD is not reading. Well, first things first, check on the following:

Step 1. Examine your SD card physically.

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 to the device.

Step 2. Insert the SD card to the Mac computer.

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.

Push in the SD card on your Mac. You will hear a sound produced if it is insecure. It holds the card so that it doesn’t slip out.

Step 3. Go to disk utility to check if Mac detects it.

For that, type disk utility in the spotlight. Click on the icon on the right or go through /applications/utilities/.

If you’d like to see it on the desktop, change preferences on Finder Preferences. Under the General tab, select External disks. Do the same under the sidebar tab.

After the steps, you can now open the SD card and access the contents through the Finder app. Enter into the SD card folder. On the right pane, contents get displayed.

However, if the above processes don’t work for you and your SD card is not reading, take a look at the next part.


Second. Fix SD Card Not Showing Up or Reading on Mac

Like every other advanced piece of technology, the SD card is bound to be affected by inevitable glitches in one way or another.

In reality, many technical reasons are associated with your SD card not showing up on your Mac.

Damage to the SD card reader slot.

It can be very frustrating because the damage might be too small even to notice. So how would you know? You can try inserting your SD card into another machine and see if it responds.

The operating system errors.

If your OS prevents your SD card from being recognized, reinstall it and try restarting your Mac. It should generally solve the issue for you.

Viral infection of the SD card

A virus can most likely affect your SD card if you share it with several people, especially Windows users with no virus protection. Viruses are dangerous.

An unsupported SD card format.

Your SD card should conform to SD 1.x, 2.x, and 3.x standards for it to work. To investigate this, check out your SD card’s manufacturer website. There are also file systems that your macOS version might not support.

The Corruption of your SD card firmware.

If your SD card gets corrupted, how would you know? You can check if your SD card has the signs as follows.

  • A black screen appears, displaying the error "SD card is not accessible. The file or directory is corrupted or unreadable".
  • Most of the contents in your SD card are missing.
  • An error message "Read/Write error on SD card" appears. You can't open any folders.
  • Materials on your SD card are visible, but you can’t copy them.
  • When you are trying to access your images or files, an error message "memory card error" pops up.
  • The SD card has been recognized, but is blank on your computer, even though you had data stored in it.

Considering the issues mentioned above, how can you repair a corrupted SD card or perform any other fix? Looking at some of the possible solutions, they include:

Method 1. Restarting your Mac

There are three ways of doing so:

Step 1. Click on the Apple icon and choosing to restart on its menu.

Step 2. Press the Power button and on the dialog box that appears, click on "Restart".

Step 3. Simultaneously hold on Control + Command + Eject/Power button. It is the most reliable option, as it’s not dependent on the OS.

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.

Method 2. Mounting your SD card in Disk utility

Even after modifying your Mac preferences, your SD card might still not be visible on the desktop. It means it’s only visible from the disk utility, thus not mounted.

Step 1. You can access Disk Utility through the spotlight. Simply type it on the search box or use the shortcut command + space.

Step 2. On the left pane, select your SD card. The right side of the screen will display the details.

Step 3. On the top sections towards the right is the mount option. If mounted, there will be an option of unmounting. Click on it to mount your SD card.

Method 3. Perform a First Aid check on your SD card

The First Aid check on Disk Utility is complete when you suspect something could be wrong with your SD card or any other external disk plugged in on your Mac.

Step 1. Go to Disk Utility.

Step 2. Select your SD card from the left pane.

Step 3. On the top options, First Aid is on the far left, click on it.

Step 4. Disk Utility performs a check on the partitions to verify its contents.

If the SD is going to fail, Disk Utility will inform you, and you should perform a backup before it’s too late.

Method 4. Repair your SD card

Perform a repair on your SD card if it did not mount successfully.

Step 1. Through Applications > Utilities open Disk Utilities.

Step 2. Select your SD card from the sidebar.

Step 3. On the details pane, click on the First Aid at the top and wait for the repair process until it completes.

Step 4. When complete, a drop-down sheet displays detailed information. Select the Repair Disk option on the bottom right.

In some cases, Disk Utility might fail to repair your SD card. In such a case, it will warn you of failure so you can make a backup.

Method 5. Repair Disk Permissions

As from MacOS X Yosemite and earlier, you can perform a repair of disk permissions on your start-up disk. You should do this because your internal hard disk permissions could in some ways be hindering your SD card from reading.

Step 1. Launch Disk Utility and select your Hard Disk from the sidebar.

Step 2. On the details pane, click on First Aid.

Step 3. Under the drop-down sheet, on the left bottom side, click on "Repair Disk Permissions".

Step 1. Go to the Utility Disk. After selecting your drive, click on "Erase" at the top.

After that, click on the erase button on the bottom right. When erasing is complete, you can now make the recovery of your files.


Third. Learn What SD Card for Mac Is and How It Works?

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 also 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 for them 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.
