How to Format a USB Flash Drive with Mac to FAT32
Computer users who use a USB might have the demand for formatting it to the FAT32 file system. Compare with the other commonly used NTFS file system on a flash drive, FAT32 has a compatibility advantage across many operating systems.
It's a universal format that is compatible with Mac OS X/macOS, Windows, Linux, and DOS systems. So, if users anticipate using the flash drive with more than one operating system, they will definitely benefit from the FAT32 file system. For Apple Mac users, there are two ways to format a USB flash drive to FAT32, namely Disk Utility and Terminal command line. Below are the detailed steps of the FAT32 format with both methods.
Method 1. Format FAT32 on Mac [Disk Utility]
To format USB to FAT32 with Disk Utility will erase all data on the flash drive, so before you doing so, please do remember to check whether you have saved useful data to another secure device in advance.
To format the USB drive to FAT32, follow the next steps:
Mac Usb Boot Disk Maker
Step 1. Connect the USB flash drive to your Mac computer.
Step 2. Go to Applications >Utilities > Double click and open Disk Utility.
Step 3. Select your USB flash drive on the sidebar, choose Erase.
Step 4. Rename the USB flash drive (optional).
Step 5. Choose the format as MS-DOS (FAT) for Format, Master Boot Record for Scheme. Then click Erase.
Wait for the process to complete, then you'll get an empty new USB flash drive with FAT32 as the file system. You can use it for saving data again.
Method 2. Format FAT32 on Mac [Terminal Command Line]
The command-line behavior does the same way to erase data with the Disk Utility. Again, create a backup before taking this action.
To format FAT32 on Mac with Terminal, follow the next steps:
Step 1. Connect the USB flash drive to your Mac computer.
Step 2. Hit cmd + space to run Spotlight, type: terminal, and hit Enter.
Step 3. Type: diskutil list and find out which disk is your USB drive.
Step 4. Type: sudo diskutil eraseDisk FAT32 MBRFormat /dev/disk2.
- sudo gives you user right.
- Diskutil calls disk utility program.
- eraseDisk commands to format.
- FAT32 sets the file system.
- MBRFormat tells disk utility to format with a Master Boot Record.
- /dev/disk2 is the location of the USB drive.
Wait for the process to complete. After this, you can type 'diskutil list' in the command again to check if the formatting has been successful.
