Clearing an SD card on a Mac can be a bit tricky, especially if you are not familiar with the process. In this post, we are going to walk you through the steps to format your SD card on a Mac.

Firstly, you will need a dongle if you are using a newer style Mac that only has USB-C connections and does not have an SD card reader. Insert the SD card into the dongle and connect it to your Mac.

In the top right-hand corner of your Mac, you will see your SD card and a little search icon. Click the search icon and type in ‘disk utility’. Double click on ‘disk utility’ and your screen should look like this. On the left-hand side, you will see your internal memory and anything external. This is where you will go to format the card.

Pay attention to the file structure that your card is in. If your card is in exFAT, you will need to change the file structure to FAT32 for it to be compatible with most trail cameras.

To format the SD card, select the erase button at the top of the disk utility screen. You can rename the card if you want to, but it is not necessary. Select the FAT32 format and then click erase. Once the computer has completed the format process, hit ‘done’ and safely eject the card.

For a 64GB card, it is important to note that the default file structure is exFAT. To change this to FAT-32, follow the same process as above.
