Nowadays, when you buy a USB drive, you can use it right out of the box with your Mac. However, unless it’s been designed for use with a Mac, it won’t be formatted using macOS’ preferred file system (either Mac OS Extended or APFS, depending on which version of macOS you’re running).

That’s because most of the computers in the world run Windows, and Windows uses a different file system, usually one known as Fat32. Drives formatted as Fat32 can be read from and written to by macOS, but it’s not optimal and you’re more likely to run into problems than if you use macOS’ native format. So, if you’ve bought a USB drive that’s formatted as Fat32, or any other format other than Mac OS Extended (also known as HFS+) or APFS, here’s how to format a USB drive on Mac. It’s exactly the same procedure if you need to reformat a flash drive on a Mac.

AweEraser for Mac is the NO.1 USB flash drive formatter for Mac. It can securely and easily format/reformat USB flash drive on Mac. And it also can permanently erase all data from the USB flash drive to avoid data recovery. If you’re both Mac users, swell; with Mac and Windows in the mix, you might be tempted to pick FAT32 when formatting that thumb drive. But FAT32 is distinctly out of date. Designed for an earlier.

It is called Freecom Mobile Drive CLS FHD Formatter Utility 1.15 or FHDFormatter for Mac. The conclusion to draw from all this is that while FAT32 has its issues, it’s the best file system to use for most portable drives. FAT32 finds support on the most devices, allows volumes up to 8 TB, and file sizes up to 4 GB. If you need to transport files greater than 4 GB, you’ll need to take a closer look at your needs. After choosing your drive, click on the 'Erase' button on the top menu bar. You will see a popup window, in that window, give the name to your drive and select a format for your USB drive. Once done, click on the 'Erase' button. This will format Write Protected USB drive on Mac using Disk Utility.

How to format a USB drive on a Mac

1. Plug the drive into a USB socket (if you have a recent MacBook or MacBook Pro that only has USB-C connectors, you’ll need a USB-C to USB-A adaptor).

2. Open a new Finder window and click on the drive. Make sure it has no files on it that you need. The process of reformatting it will wipe all the data from it.

3. Once you’ve copied any files you need from the USB drive to your Mac, go to Applications>Utilities and double-click on Disk Utility.

4. Click on the USB drive in the sidebar and then choose Erase from the toolbar at the top of the window.

5. In the window that drops down type a name for the formatted drive in the box next to Name.

6. Choose a format from the dropdown menu.

7. Dmss app for mac. If you have previously stored sensitive data on the drive, click the Security tab.

8. Choose a security level using the slider. The further to the right you move the slider, the more ‘passes’ the erase tool will make and the more securely files will be deleted. However, it also increases the time it takes to format the drive quite considerably.

9. Click Ok then click Erase.

Tip: You don’t need to erase a whole drive to delete files securely. If you have confidential files or sensitive data you need to remove from your Mac completely, you should use CleanMyMac’s File Shredder. It’s specifically designed to securely delete sensitive data and will render it unrecoverable. You can download CleanMyMac X for free here.

Which format to choose?

If your Mac is running macOS High Sierra or later, you have two options for file formats: APFS and Mac OS Extended. Which should you choose? The key point is that disks formatted as APFS won’t be recognized by Macs running versions of macOS older than High Sierra. So if you think you might need to plug the USB drive into a Mac running an older version of macOS, format it as Mac OS Extended.

APFS is optimized for SSD (solid state drive) such as flash drives, so if you reformat a flash drive on a Mac, you should definitely choose APFS (unless you plan to use it with a pre-High Sierra Mac, of course). Even on hard drives, however, APFS is faster and more reliable than Mac OS Extended.

Finally, if you plan to use the USB drive as a destination for Time Machine backups, choose Mac OS Extended. Time Machine can’t currently back up to an APFS disk and if you select one for use with Time Machine, it will offer to reformat it as Mac OS Extended. You can, however, backup an APFS formatted disk to a Mac OS Extended Time Machine drive.

How to format a USB drive to FAT32 on a Mac

The main reason for formatting a USB drive as Fat32 on a Mac is that you want to be able to use the drive on a Windows PC, as well as a Mac — perhaps to transfer files between the two machines. You may also be preparing the drive for use as, say, a storage device for a media player or to record TV programmes on a TV with a USB port.

The fact that Fat32 can be read from and written to on both Mac and Windows makes it very versatile. However, there is a significant limitation — individual files have a maximum size of 4GB. So, if you’re using the USB drive to store large video files, you may run into trouble. There is a solution, however, exFAT. Unlike FAT32, exFAT doesn’t have a maximum file limit. Better still, it can be read from and written to on any Mac running Mac OS X Snow Leopard or later and on Windows.

To format a USB drive in FAT32 or exFAT:

5. Type in a name for the formatted disk.

6. Click on the Format menu and choose either MS-DOS (FAT32) or ExFAT.

7. Click Erase.

You need to format your flash drive on Mac to make it compatible with your Mac. We’ll teach you how in this article. Read away!

Here are the tactics you’ll learn about in this post.

Part 1. Why Format Your Flash Drive?

There are various reasons why you have to format your flash drive on Mac. Here are the three common ones:

Ensure the flash drive’s full compatibility with Mac. Most flash drives are pre-formatted for use with Windows.

The difference between macOS and Windows is that they make use of different file systems. Mac uses either Mac OS Extended or AFPS as the file system, while Windows usually uses FAT32.

Drives that are formatted as FAT32 can still be used with macOS, but there is a bigger chance that you’ll encounter issues along the way.

Aside from that, Time Machine doesn’t work with drives that are not fully compatible with Mac. Time Machine is a built-in feature of Mac that backs up your files to an external storage device such as your flash drive.

Free up space in your flash drive. USB drives have limited memory space. Sometimes, deleting unnecessary files or transferring a few of them to your PC is enough.

Sometimes, it isn’t. That is when formatting your USB drive becomes the best solution.

Get rid of viruses and other issues. Flash drives are popular for their portability, but they can also carry viruses that can spread to other computers.

Formatting a flash drive on Mac is an easy yet effective way to remove them. Although macOS is generally much safer and more secure than Windows, this doesn’t mean that your Mac can’t be affected by viruses.

Part 2. How to Format a Flash Drive on Mac

Before you proceed with formatting your flash drive, you should first consider which format you are going to use. Selecting the correct format is crucial as it will have an impact on its compatibility with your Mac.

Format Flash Drive For Mac

Certain formats work better on specific versions of macOS. The format that you set is something you’ll have to stick with for a long time, so it’s best if you make the right decision from the very start.

Below are the available formats and when best to use them.

APFS. Short for Apple File System, APFS only works with Mac running on High Sierra or later.

It is optimized for solid state drives (SSD) like flash drives, and this guarantees a faster performance than Mac OS Extended.

If you intend to use your USB drive only with a new Mac, APFS is highly recommended. The downside to it is that it isn’t Time Machine-compatible.

This means you cannot set the flash drive as the destination of your backup.

Mac OS Extended. If your Mac is running on macOS Sierra or below, this format is the way to go. Nevertheless, Mac OS Extended works with High Sierra and up as well.

This would work well if you think you would need to use your drive in an old Mac. It has some catching up to do in terms of speed, though.

On the bright side, you can use your flash drive to create backups via Time Machine.

FAT32. The most versatile in the list, FAT32 will allow you to use your USB drive on Windows as well as a Mac. In fact, it is the most widely compatible file system.

It works on most video game consoles, media players, and other devices. However, it can only support individual files up to 4GB in size.

We don’t suggest using this format if you plan to store large files like videos.

exFAT. This is closely similar to FAT32 in terms of compatibility. It works on both Windows and macOS too.

However, it is not supported by as many consoles and devices as FAT32. The great thing here is that it doesn’t have a file size limit.

If you want full compatibility with Mac, choose between APFS and Mac OS Extended. If you expect to transfer files between a Windows computer and a Mac, you should decide on either FAT32 or exFAT.

If you are merely freeing up space or getting rid of viruses in your flash drive, simply select the previous format.

Now, have you decided which format would best suit you and your Mac? If you have, refer to our step-by-step guide on how to format a flash drive on Mac.
