Switch on your Mac and connect the USB drive using one of the USB ports. Ensure that the USB is connected correctly.
- Choose Utilities
Now launch the application program and click on the Utility option on the right side window.

After everything is set, now is the time to begin the formatting. To activate it, just click on the Erase tab at the lower right part of the interface.
- Reconfirm and format
The program will display another confirmation message before the format starts. Select the Erase option one more time to begin formatting the USB drive. After this, your flash drive can be used with Mac or other computers.
Part 2: Which Format to Choose When Formatting?
This is one of the most overlooked parts of the whole process. Many users do not know the importance of the file system when it comes to storage devices. Everything would be simple if every operating system in the world accepted all file systems. Then you would be able just to use any file system and call it a day. However, that is not the case.
A file system is like a set of rules that determine how data must be written to the storage device. There are mainly five types of file systems available that are in everyday use.
FAT32: A file system that has been in business since the early 1980s. They were once the goto file system for formatting windows based devices.
NTFS: NTFS or New Technology File System is the current standard in windows machines. It is the recommended file format for Windows computers. However, they are not suited for Mac OS.

ExFAT: A modified version of FAT32, which is capable of support higher data transfer bandwidths. They are readable by both Windows and Mac devices.
HFS+: Introduced in 1998 for Mac systems. It was the most common Mac file format until 2017. HFS+ is not readable by Windows machines.
APFS: This is the latest file format system used by Apple devices. When compared with HFS+, APFS is made for solid-state storage devices. APFS is only readable by Mac devices.
Now, when you are formatting a USB drive on Mac, you have an essential decision to make whether the USB should be readable by windows machines and Mac machines or just by Mac and not readable in windows.
If you want the USB device to be readable by both Mac and Windows devices, then you have three options – NTFS, FAT, or ExFAT. The macOS can read the NTFS files, but you cannot write anything to the storage device. With ExFAT, you can write and read on both MAC and Windows PCs and is our recommended option for an ultra-portable USB device.
If you want the storage device to only show up on Mac systems, then format your storage device with APFS.

ii. Terminal Command Line
The terminal command line in Mac can be used to format USB devices. This method can be used when you are unable to format the USB device through Disk Utility. As always, having a backup option will save you when plan A fails for some reason.
Let us go through the exact steps in formatting your USB drive to FAT32 on Mac using the command line. Make sure that you enter the commands in the right syntax. Follow the guide given below for more info.
Step 1 Connect the USB device to the Mac. Ensure that the computer has read the device.
Step 2 Press Command and Spacebar simultaneously. Type in 'Terminal' and press enter.
Step 3 Type in the command diskutil list and this will display all the connected storage devices to your Mac.
Step 4 Now type in sudo diskutil eraseDisk FAT32 MBRFormat /dev/disk2, and your USB device will be formatted to the FAT32 file system.
The command eraseDisk is used to delete the data in your USB device completely. It is an essential step before formatting and cannot be avoided. Other supported file formats can replace the FAT32 file format. After the format process is over, you will see that that file format has now been changed to the FAT32.

How to format internal and/or external drive to work properly on Mac and Windows computers?
External data storage devices such as USB flash drives, external Hard Disk Drives (HDDs), and Solid State Drives (SSDs) provide one of the easiest ways to transfer files between separate computers without accessing the Internet. This option is often used when attempting to move very large files. The method is also chosen by people who work with media data that imposes various limitations and automatic optimizations when transferring via Internet. Despite the advantages of using external data storage to transfer content, some experienced users encounter problems caused by the difference between operating systems. This article addresses these issues.
A common issue discussed by users within various technical support forums is that of USB flash drives not working on their computers. This is a cross-platform problem that Windows and macOS users often experience. For example, a photographer may provide you with a USB flash drive with stored photos and videos from your birthday party, but you cannot access them on your system. This is the result of differences between operating systems on computers. Windows and macOS use separate file system formats. PCs with Windows operating systems use New Technology File System (NTFS) while Macs with macOS operating systems use Hierarchical File System (HFS+). By default, USB flash drives and external storage are formatted with the NTFS file system - this works flawlessly on PCs, while Mac computers are able to read data in the format, but struggle to write using this type of storage. Fortunately, there is a simple solution: format your external storage with the File Allocation Table (FAT32) or Extended File Allocation Table (exFAT) file system. In this article, we describe the differences between these two file systems and how to format external storage using a Mac computer.

Which file system to choose - FAT32 or exFAT?
As mentioned above, both file systems are compatible with Windows or macOS/OS X operating systems. Naturally, the question is: which should you choose? To make the choice easier, we describe both file systems and their features below.
Starting with FAT32 [on a Mac, known as MS-DOS (FAT)], this file system is fully compatible with all versions of Windows and Mac operating systems. Therefore, even the oldest versions of operating systems such as Windows XP SP1 and OS x 10.5 Leopard are compatible. As well as computers, the FAT32 file system is supported by PlayStation 3, Xbox 360, and most cameras. This particular file system does contain file size restrictions. For example, the maximum size of supported files is 4GB (you cannot write files larger than 4GB). Also, you cannot create a startup drive for Mac computers within storage media that uses the FAT32 file system. If, however, you are not planning to use external storage to transfer large files or create any executable partitions (such as a Mac startup drive) the FAT32 file system might be an option, since this format is supported in all versions of the operating system.
exFAT is a newer file system format and has the biggest advantage when compared with FAT32: there are no restrictions on file or partition sizes stored. Therefore, you can write a file of, for example, 1TB size and create partitions of 5TB within the device. Despite this improvement of available data size, some older versions of operating systems are no longer compatible with this file system format. The oldest versions of operating systems compatible with exFAT are listed below:
- Mac OS X Snow Leopard 10.6.5 or later
- OS X Lion
- Windows XP SP2 or later (with an additional update for exFAT support)
- Windows Vista SP1 or later
- Windows 7
Unfortunately, as well as some old versions of operating systems, the exFAT file system format is not supported by various cameras, video games consoles, and other devices able to read and/or write to external storage. If you will be using a USB flash drive or external storage device with any of these, the required format is FAT32. Otherwise, if the device is to be used only with computers with modern versions of operating systems, the recommended format is exFAT.
Format the drive with Mac computer
Firstly, bear in mind that formatting the drive will erase all content stored on it. Mac computers are capable of formatting any storage device (internal or external) such as HDD/SSD, USB flash drive, and external storage. Even if the Mac is unable to mount the storage, following this method will enable you to format the storage. Begin by connecting the storage device to your Mac, and then launch Disk Utility using Spotlight. Simply use the keyboard shortcut of Command and Spacebar, type Disk Utility, and then press return. Alternatively, open Finder and go to Applications, open Utilities, and then launch Disk Utility. Select the drive you wish to format from the list in the left sidebar of the Disk Utility window.
Then click the Erase button at the top of the window, in the new pop-up window, and type the name of drive. Then click the drop-down menu beside Format and select MS-DOS (FAT) - the FAT32 file format - or exFAT. These formats are described above.
If you are not planning to use this drive as the Windows startup disk or use it with the oldest version of the operating system, do not change the Scheme. Select Master Boot Record.
Finally, when all preferences are set, click the Erase button. The formatting process duration depends on size and type of the drive. A hard disk drive will take longer to format than a flash drive. NOTE: formatting will erase all existing data on the drive.
