Before you format a flash drive
MacOS supports HFS plus file system. HFS stands for Hierarchical File System.
Apple introduced this file system in 1985 to replace the existing Macintosh File System or MFS. HFS filesystem is modified into HFS plus (Modernly called as MacOS Extended). Before you format a flash drive it is suggested to know what file system your flash drive is in.
Check flash Drive’s File System
You don’t need to do anything special to know your flash drive’s file system. There are 2 ways you can do this.
Method 1: Using Finder
Plug in your flash drive. Now open the Finder and look for your USB device. Then right-click on the drive’s name. Select “Get Info” from the list of options opened.
A new window will open. Just to the right of “Format” is your drive’s file system.
Method 2: Using Disk utility app
Open the Disk Utility app from the utility folder available in the application. Your drive will be on the left column of the window. Click on the partition. Here you can check the current format of your flash drive.
If your flash drive’s file system is MS-DOS or ExFAT you can use it as it is without further formatting. But if it is NTFS, format your flash drive to make it completely compatible with MacOS.
How to format a flash drive on Mac?
Disk Utility application in MacOS is the best option to format a flash drive on MacOS. You can launch this app in two ways.
Step 1: Press Space while holding your command button. A search box will open. Type Disk Utility in the search box and press enter. Alternatively, Open the Finder window and select applications on the left sidebar. Navigate to Utilities and then Disk Utilities.
Step 2: Search for your flash drive on the sidebar of the Disk Utility app and select it by clicking on its name.

Here you can change the name of your USB drive if you wish. This name will be visible on other devices as well if you plug your flash drive into them. Just below the Name section, you can see a section called “Format”.
You will need to choose a format option to change your flash drive’s file system. But which format to choose is the big question now! No need to worry. Read the description of each format given below and choose the format of your choice.
Types of filesystems
Mac OS Extended (Journaled)
This format is considered as default file system format of the Mac OS X drives. It also supports OS X Lion, like Versions. This format will allow you to use your flash drive on Mac without any limitations.
With Mac OS Extended (Journaled) format, you can setup OS X startup drive. Make sure you have right files and know how to do it. If you have any issues with a built-in drive you can boot from the external disk. This file system format is highly recommended for MacOS. But you cannot write this flash drive from windows PC once you have formatted it as Mac OS Extended (Journaled). You can read files though.
OS X Extended (Case-sensitive, Journaled)
Go for this type of filesystem if you really need it for some reason. For OS X Extended (Case-sensitive, Journaled), the word “File” is different than “file”. It means it’s case sensitive as the name suggests.
OS X Extended (Case-sensitive, Journaled, Encrypted)
Same as filesystem just mentioned above but of course with encryption.
OS X Extended (Journaled, Encrypted)
To use a flash drive with this filesystem you will have to set up a password & enter it whenever you plug in your drive into any device.
MS-DOS (FAT)
This is just a name for the FAT32 filesystem in Disk Utility application. FAT32 supports to almost all of the operating systems in the world. This allows you to transfer files from one operating system to other. The best thing about this filesystem is its support to video game systems which include Xbox 360 and PlayStation. This filesystem can be called a universal system. The limitation about FAT32 filesystem is it doesn’t allow files which are bigger than 4 GB in size and also you cannot create a startup drive unlike Mac OS Extended (Journaled).
ExFAT
This is a new type of filesystem and it supports MacOS X 10.6.5 and later. It is same as FAT32 but it supports files larger than 4 GB. As this filesystem is relatively new, it does not on relatively older versions of Mac OS X. If you don’t use any older version of the operating system, you can use this type of filesystem.
Use ExFAT for this tutorial if you wish to use your flash drive on windows as well on MacOS.
Step 4: For this tutorial, you can ignore the Scheme option which we use if you wish to boot from your flash drive. Click on erase button to format your flash drive.
Voila! You have formatted your flash drive now. You can eject drive by right-clicking on its name in the left sidebar and click on “Eject”.

Part 1: How to Format a USB Flash Drive on Mac

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.

- 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.
