Click the Format pop-up menu, then choose a file system format. (Optional) If available, click Security Options, use the slider to choose how many times to write over the erased data, then click OK. Secure erase options are available only for some types of storage devices. Click on the “Erase” tab then pick “Mac OS Extended (Journaled)” — my recommendation for flash drive formats, though it does make it unreadable on a Windows PC — and enter a new name for the device if you’re so inspired: Take another minute to quadruple check that you’ve picked the right device and click on “Erase”.

Bonus: How to Recover Lost Data After Formatting USB Drive

Part 1. What You Should Do First Before Formatting USB Drive on Mac

Make sure that уоu know clearly whаt уоu are doing whеn you begin the whole formatting process, which will еrаѕе your еntirе hаrd drivе.

To avoid formatting the wrong disk, firstly remove the USB drive from Mac, check the title of other storage disks, then insert the USB disk again and note the name of the disk. Next, drag the USB data to a safe location for backup/recovery measures before formatting it. Then you are set to get it done!

Part 2. What Is the Best Format for USB Drive on Mac?

You'll be given several format options when you try to format a USB drive on Mac, including Mac OS X Extended (Journaled), Mac OS X Extended (Case-sensitive, Journaled), Mac OS X Extended (Journaled, Encrypted), Mac OS X Extended (Case-sensitive, Journaled, Encrypted), MS-DOS (FAT) and ExFAT. If you are using macOS 10.13 or later, you'll also see an option named APFS, which is the default file system of macOS 10.13 and later.

1APFS (Apple File System)

APFS is a new file system for macOS. It's the most appropriate format for SSD. However, you need the latest macOS to write to this file system. If you're sure that you don't need to use it on a Mac running old version in the future, then you can format your USB drive to APFS.

2Mac OS X Extended (Journaled) & Mac OS X Extended (Case-sensitive, Journaled)

Mac OS X Extended, aka HFS+, is the default file system before APFS for macOS 10.12 and earlier. It doesn't put a limit on the size of files you can save on the drive, which is the greatest advantage. Windows-running computers can read the files formatted to Mac OS X Extended but can't write to them. And this file system is necessary if you plan on using the drive for Time Machine backups.

The biggest difference between Mac OS X Extended (Journaled) and Mac OS X Extended (Case-sensitive, Journaled) is the latter one is case-sensitive to folder names. For example, 'file' is different from 'File'. Therefore, if you do not have special needs, just ignore this option.

3Mac OS X Extended (Journaled, Encrypted) & Mac OS X Extended (Case-sensitive, Journaled, Encrypted)

These two are basically the same with the previous two but with encryption, which means you have to provide the password whenever you connect the drive to your Mac.

4MS-DOS (FAT)

This is Disk Utility's name for FAT32 file system. As the most widely compatible file system, it suits both Windows operating system and macOS. Therefore one can easily transfer data between PC and Mac using a USB drive formatted this way. However, a USB drive formatted to FAT32 doesn't support long file names and an individual file cannot be larger than 4GB.

5ExFAT

ExFAT is the improved version of the older FAT32, which offers larger storage space and supports files larger than 4GB. Of course it also supports transferring files between PC and Mac as a cross-platform file system.

To arrive at a conclusion, if you need to transfer smaller files between operating systems, choose MS-DOS (FAT) or FAT32. And with no doubt, ExFAT will be the best format for USB drive on Mac for larger files.

Part 3. How to Format USB to FAT32/ExFAT on Mac

As earlier stated, you need to first back up your USB drive before formatting it as the formatting operation will wipe all the data. Now, you can follow the steps highlighted below to get the USB successfully formatted.
