USB drives are a convenient way to store and transport data. And they usually work well with Windows and macOS. However, if your USB drive is not showing up on Mac, you may have trouble accessing the data on it. Luckily, there are quick and easy solutions to this problem.
Why is your Mac not recognizing the USB drive?
There are several reasons for your USB drive not showing up on Mac. The most common one is that your USB drive is formatted in a file system that is not compatible with Mac. Another reason may be that permission issues are preventing your Mac from accessing the data on the drive.
The most common ones are HFS+ and FAT32. While NTFS only works with the Windows system.
Public computers are more exposed to virus attacks, which can make your USB drive infected with malware and damage the device.
This helps prevent data corruption and keeps the drive healthy.
If you’re wondering how to fix the USB drive not showing up on Mac, here are a few things you can try.
Important: At any moment you can contact a professional to help you. Apple support always helps their client to fix any issue with their devices.
