If you have an SD or micro SD card you want to reformat with your Mac it’s a pretty easy process. Read on to learn how.
Before you start, you need to mount the SD or micro SD card on your Mac. If you have a Mac with an SD card slot, use that. If not, you’ll need an SD card adapter like the Anker 8-in-1 card reader. It’s a good deal at US$9.99 on Amazon.
To reformat an SD or micro SD card on your Mac, do this:
- Launch Disk Utility. It’s in Utilities folder inside the Applications folder.
- Find and select your SD card in the column on the left
- Click the Erase tab
- Choose the format you want from the pop-up menu
- Click Erase
Disk Utility won’t let you format 32 GB and smaller SD and micro SD cards as MS-DOS (FAT32). You can see the option, but it’s grayed out. That’s because exFAT is the format you should use instead.
