There are two types to format SD card on Mac. You can format your SD card using the SD card Formatter tool and format the SD card without the SD Card Formatter tool on macOS.
Below Steps are helping you to format the SD card without using SD card Formatter:
Step 1: Connect SD Card To Your MacBook.
Some Macs come with an inbuilt SD card slot. If you have a built-in SD card slot, you can insert the SD card directly into that. If you’re using a micro SD card, but the micro SD card into the SD adapter first and then put it into your computer’s USB port.
Important Note: Make sure you saved all the files from your SD card that you want to keep to your computer before moving to the next step because formatting the card will delete all of the data stored in the SD card.
Step 2: Open Disk Utility Application.
Disk Utility found in the applications folder under the “utilities”. Or you can use Spotlight (the magnifying glass icon at the top right of your desktop) to search for it by simply clicking on the icon and then typing “disk utility” in the search box.
Step 3: Identify Your SD Card .
On the left side of the Disk Utility’s screen has a list of your Mac’s internal and external drives. The SD card should show up in the External drive section. If the SD card hasn’t been formatted before, it might have a name like “NO NAME” or “UNTITLED”.
Step 4: Select Erase Function.
From the list of functions given at the top, click the Erase.
Step 5: Choose The File System Format.
In the Format drop-down menu, you have several options. The only ones we need are MS-DOS (FAT) and ExFAT. Which option to choose depends on what size storage cards you’re using. If your SD card is 64 GB or more, choose ExFAT. If your SD card is 32 GB or less, choose MS-DOS (FAT).
Step 6: Click Erase
Click Erase. After a few moments, you will get a message that the process is completed.
