menu_default hide_default

SD card formatting could go wrong in several ways. I occasionally format an SD card on my Mac, and I'd always look out for the correct file system format. A wrong choice of file system during formatting will definitely create an error and render your device incompatible with other devices.

Although there are quite some options to choose from such as MS-DOS (FAT), ExFat, OS X Extended (Journaled), etc., it is recommended to stick with the ExFat; since this format is compatible with most devices. Once I attempted formatting an SDXC card using my MacBook, but now I know better. I'll explain more about how to format your SD card for Mac in a while.

What You Should Check Before Formatting an SD Card on Mac

It is best to format your SD card using the formatting function of the device you intend to use with - Especially, if your SD card is either an SDHC or SDXC; both of which are not recommended to get formatted on a Mac.

Before heading on to format your SD card, you need to back up all the content of the SD card. You should do this because all the content of an SD card gets wiped clean after formatting. Finally, make sure the SD card's switch is unlocked.

Check Your SD Card Format Type

There are several formats in which an SD card can get formatted including MS-DOS (FAT), ExFat, OS X Extended (Journaled), OS X Extended (Case-sensitive, Journaled), OS X Extended (Journaled, Encrypted) and OS X Extended (Case-sensitive, Journaled, Encrypted).

The option you choose depends on the size of the SD card and Mac OS version. If your SD card is 64GB or larger, and you are running Mac OS Lion or later, you can select ExFat. If your SD card is smaller than 64GB or your Mac OS is Snow Leopard or earlier, choose MS-DOS (FAT). Do not select any of the OS X Extended versions as this may cause the SD card incompatible with other devices.

Check If There Is a Card Slot on Your Mac

Some Macs do not have an SD card reader - In which case, you'd have to purchase something called an SD card adapter. These are USB SD card reader with a slot for standard SD cards.
