How to fix USB flash drive not showing up on Mac?

There are seven solutions to fix USB flash drive not showing up on Mac or Mac not recognizing USB device:

Fix 1: Check USB cable, USB connection and USB ports.

Jump drives are directly plugged into USB ports on Mac while SD cards and NM cards need card readers before you access them through USB ports. That in-between connections, actually, could be the first cause for USB drive not showing up on Mac.

Then, how to check if the USB flash drive is recognized by Mac?

It's easy to confirm that your Mac has already recognized the USB device when it is not showing up in the Finder or the desktop. Simply click the Apple logo at the upper left of your Mac > About this Mac > System report > USB, and then all your connected USB devices will show up with detailed information as the picture below.

If the USB flash drive not detected by Mac due to hardware problems, you won't see the connected USB device under the USB Device Tree.

In case it's the USB port, cable, or card reader that stops your USB drives working on the Mac, you'd better try these things before you proceed with other solutions.

Try to re-plug the USB flash drive into your Mac and see if it shows up.

Sometimes, the Mac just is zoning out and fails to recognize the USB flash drive, or you didn't plug the USB drive into USB port in a right way at the first time. So, hopefully, the USB flash drive would show up after a second try.

Try another USB port to connect this USB flash drive.

Most computers, including PC and Mac, have multiple USB ports. And some USB ports may be deformed, lack of power, or dusty. In this case, simply try another USB port to connect this USB flash drive to your Mac.

Reset USB ports on Mac to detect USB drive

Resetting USB ports on Mac is another way to solve Mac not recognizing USB flash drive problem.

• 1. Disable SIP.
• 2. Download, install and launch iBoysoft Drive Manager on your Mac and select 'Remount USB storages' to reset USB ports.

Try to connect the USB flash drive directly to your computer, not via USB-C adapter or USB hub.

Some models of MacBook Pro and MacBook Air has only one USB 3.0 port, which causes the requirement of an additional USB adapter for more hubs. Inevitably, such transition could be unstable for power supply and data transferring, especially when you bought some cheap and low-quality adapter. Thus, try to connect the USB flash drive directly to USB port on your Mac this time.

Try another USB cable or a newer card reader.

Occasionally, you have used the same USB cable or SD card reader for years, which means the cable might broken or the card reader is out of date and some new features are not supported by the old card reader. As a result, the USB flash drive or the SD card is not showing up on Mac. Under this circumstance, simply get a new one and replace it.

Check the type of your USB flash drive by color.

Usually, the USB 1.0 features a white plastic color, while USB 2.0 is black, and the USB 3.0 is blue.USB 3.0 is usually a blue USB inserts. But all USB ports on Mac computers that support USB 3 don't have blue inserts. In this case, if you connect a USB 2.0 flash device to USB 3.0 slot on Mac, the speed will only reach that of the USB 2.0. As a result, the data transfer rate of the thumb drive would be lowered and the thumb drive won't work optimally.

Fix 2: Change Finder preferences to show up USB flash drive on Mac desktop

Occasionally, your Mac has already detected the USB flash drive but you cannot find the connected USB device on Mac desktop. Thus, you should go to Finder > Preferences > General and make sure the 'External disks' option is checked. Then you'll see the connected USB flash drive showing up on Mac desktop.

Fix 3: Change Finder preferences to show up USB flash drive in Finder

Go to Finder > Preferences, switch to Sidebar tab, and check 'External disks' option under Locations.

You will see the connected USB flash drive in Finder's sidebar.

Bonus tips for using USB flash drive

The USB flash drive, pen drive, jump drive, or whatever you call it, is convenient but also fragile to store data based on its special memory units and shape. Then, how can we protect it from corruption and not showing up on Mac?

You may need these tips:

1. Don't put USB flash drives in the pockets of your pants of T-shirt, especially, when it's naked. This could keep your drive away from moisture from your body and dust on your clothes. More importantly, it can avoid accident break off when you sit down or bump into something.
2. Don't unsafely eject the USB flash drive. Even though it's inevitable for portable drives to be plugged and unplugged frequently, you can make sure you eject it safely and properly every single time.
3. Create a backup of your data. Although you have been taking good care of your USB flash drive, you should know that it has a limited life span. Therefore, to avoid unexpected data loss, you'd better do a regular backup of your files.

Mac users who choose to upgrade (or already have upgraded) to Mac OS Catalina (10.15.x) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm AND reenable the built in smart card ability (very bottom of macuninstall link above)

If you purchased your Mac with OS Catalina (10.15.x) already installed, you can skip the uninstall part above and follow the instructions below.

6 'high level' steps needed, follow down the page to make this a painless systematic process

Step 1: Is your CAC reader Mac friendly?

Visit the USB Readers page to verify the CAC reader you have is Mac friendly.

Visit the USB-C Readers page to verify the CAC reader you have is Mac friendly.

'Some, not all' CAC readers may need to have a driver installed to make it work.

NOTE: Readers such as: SCR-331 & SCR-3500A may need a firmware update (NO OTHER Readers need firmware updates).

Information about these specific readers are in Step 2

Step 2: Can your Mac 'see' the reader?

Plug the CAC reader into an open USB port before proceeding, give it a few moments to install

Step 2a: Click the Apple Icon in the upper left corner of the desktop, select 'About This Mac'

Step 2b: Click 'System Report..' (button)

Step 2c: Verify the CAC reader shows in Hardware, USB, under USB Device Tree. Different readers will show differently, most readers have no problem in this step. See Step 2c1 for specific reader issues.

Step 2c1: Verify firmware version on your SCR-331 or GSR-202, 202V, 203 CAC, or SCR-3500a reader. If you have a reader other than these 5, Proceed directly to step 3

Step 2c1a-SCR-331 reader

If your reader does not look like this, go to the next step.

In the 'Hardware' drop down, click 'USB.' On the right side of the screen under 'USB Device Tree' the window will display all hardware plugged into the USB ports on your Mac. Look for 'SCRx31 USB Smart Card Reader.' If the Smart Card reader is present, look at 'Version' in the lower right corner of this box: If you have a number below 5.25, you need to update your firmware to 5.25. If you are already at 5.25, your reader is installed on your system, and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.
