About APFS and Mac OS Extended
Disk Utility in macOS High Sierra or later can erase using either the newer APFS (Apple File System) format or the older Mac OS Extended format, and it automatically chooses a compatible format for you.
How to choose between APFS and Mac OS Extended
Disk Utility tries to detect the type of storage and show the appropriate format in the Format menu. If it can't, it chooses Mac OS Extended, which works with all versions of macOS. If you want to change the format, answer these questions:
- Are you formatting the disk that came built into your Mac?
If the built-in disk came APFS-formatted, Disk Utility suggests APFS. Don't change it to Mac OS Extended. - Are you about to install macOS High Sierra or later for the first time on the disk?
If you need to erase your disk before installing High Sierra or later for the first time on that disk, choose Mac OS Extended (Journaled). During installation, the macOS installer decides whether to automatically convert to APFS—without erasing your files. - Are you preparing a Time Machine backup disk or bootable installer?
Choose Mac OS Extended (Journaled) for any disk that you plan to use as a Time Machine backup disk or as a bootable installer. - Will you be using the disk with another Mac?
If the other Mac isn't using macOS High Sierra or later, choose Mac OS Extended (Journaled). Earlier versions of macOS don't work with APFS-formatted volumes.
How to identify the format currently in use
If you want to know which format is currently in use, use any of these methods:
- Select the volume in the Disk Utility sidebar, then check the information shown on the right. For more detail, choose File > Get Info from the Disk Utility menu bar.
- Open System Information and select Storage in the sidebar. The File System column on the right shows the format of each volume.
- Select the volume in the Finder, then choose File > Get Info from the menu bar. The Get Info window shows the Format of that volume.
If your disk or volume doesn't appear, or the erase fails
- Shut down your Mac, then unplug all nonessential devices from your Mac.
- If you're erasing an external drive, make sure that it's connected directly to your Mac using a cable that you know is good. Then turn the drive off and back on.
- If your disk or volume still doesn't appear in Disk Utility, or Disk Utility reports that the erase process failed, your disk or Mac might need service. If you need help, please contact Apple Support.

- If you can't start up from macOS Recovery, you can use a different startup disk instead.
- If Disk Utility shows a Security Options button in the Erase window, you can click that button to choose between a faster (but less secure) erase and a slower (but more secure) erase. Some older versions of Disk Utility offer the option to zero all data instead. These secure-erase options aren't offered or needed for solid-state drives (SSDs) and flash storage.
This simple guide will teach you How to Format a Flash Drive on Mac. Not only this, we will help you pick the best file system for your usb flash drive that you are planning to use on a Mac.
Majority of 49.4% of desktop and laptop computer users in the world use Windows operating system. In contrast, only 27.4% of users use MacOS, obviously for their apple computer. That’s the reason why most of the flash drives in the market are available in Fat32 or NTFS formats which are the most preferred format for windows. Although the first one, Fat32 is completely compatible with both MacOS as well as Windows, it has some limitations. Fat32 can store files only up to 4 GB of size. The latter one, NTFS is mostly used on the Windows operating system and not an optimal option for MacOS. Extra work is needed to use NTFS on MacOS. If you want to use your flash drive solely for MacOS, it is highly recommended to format your flash drive.

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.
Step 3: Now Click the “Erase” button which is located just below the title bar of the window which says “Disk Utility”. This will erase your whole drive and make it a single partition.
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)
![Versions Versions](https://static.makeuseof.com/wp-content/uploads/2018/10/Mac-Disk-Utility-Erase-Flash-Drive.png)
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
Format Disk Mac Os X
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”.
