How to Access USB Drives on Mac

This practical guide walks through how to access USB Drives on Mac. It organizes the required steps, settings, and checks so you can complete the task with fewer mistakes.

Accessing a USB drive on a Mac is usually pretty easy, but if you're new to macOS or have problems with the drive, you might have trouble finding it. Today's article shows you exactly how to find and open a USB drive on your Mac.

Find the USB Drive on the Desktop

By default, you should be able to find your USB or external hard drive on your Mac's screen. Connect the USB drive, then choose the yellow minimize button in the top left corner of all open windows to display the macOS desktop.

If you see an icon representing a USB drive, just double-select to open it. If not, follow the next section to access the USB drive using Finder.

Find the USB Drive Using Finder

Apple's Finder is equivalent to file Explorer in Windows. To open it, select the blue smiley face icon on the left side of the Dock. If you can't see the Dock on your Mac, move your mouse pointer to the bottom of the screen to make it appear. If that doesn't work, try moving your mouse to the left or right side of the screen if you've customized the Dock's position.

After opening a Finder window, you can see your USB drive in the left sidebar, under the Locations Heading.

If you still can't find your USB drive, open Finder > Settings From the menu bar at the top of the screen. Then, select the Sidebar Tab and make sure External disks Under the Locations Heading is enabled.

If your Mac can detect the USB drive, this will make the USB drive appear in the Finder sidebar.

Can't Access USB Drive on Mac?

If you can't find the USB drive in Finder, it's likely that the USB drive has a problem or uses a format that doesn't work with macOS.

Check the USB Drive Format

To check the format of a USB drive, select Cmd + Space To open Spotlight, then type "Disk Utility" And select Return (or Enter ) to launch the macOS Disk Utility tool. Then, select the USB drive from the sidebar to display the drive format below its name.

If the USB drive is in ExFAT, FAT32, APFS, or Mac OS Extended format, the Mac will have no trouble detecting it. select the First Aid Button in Disk Utility to fix any problems with the drive, then try accessing the drive again in Finder.

However, if it uses Microsoft's NTFS format, the Mac will still be able to read it but will not write to it. So, if you need both read and write support, you can reformat your external hard drive in macOS to the appropriate format. If reformatting isn't an option, explore other ways to use NTFS drives on your Mac.

Check for Physical Problems with the Drive

If your USB drive or external hard drive doesn't show up in Disk Utility, there may be a physical problem with the drive or USB port on your Mac. Instead, try using another drive or another port.

Also, try using the USB drive with another computer to see if it works with that computer. If it doesn't work with any other device, you can be sure that the problem is with the drive and not with the Mac.

Make Sure the Drive's Contents Work with macOS

If the USB drive shows up on your Mac but is empty despite its content, it might be a problem with the type of file you're trying to transfer. Not all file types work with macOS. So make sure the files you're trying to transfer to your Mac are compatible with macOS.

Sometimes, no matter how hard you try, it seems impossible to access a USB drive on your Mac. In this case, it is often easier to use another type of storage to transfer data, such as cloud storage.

Choose one of the cheapest cloud storage services available, connect the USB drive to another computer that supports it, and upload files to the cloud. Then, download the files to your Mac from the cloud.
