If you are looking for solutions for solving read-only WD My Passport on Mac problem, you have come to the right place. This post will explain three common reasons why your WD My Passport is not writable and corresponding fixes.

Why is the WD My Passport read-only?

Sometimes, the WD external hard drive is read-only on Mac when you just got a brand new WD external hard drive. In other times, it suddenly became read-only after you have been using it for a while. The most common reasons for a read-only WD external hard drive, like WD My Passport, are listed below:

• Your WD My Passport hard drive is NTFS-formatted.
• You have read-only permission to access the WD My Passport hard drive.
• Your WD My Passport hard drive is corrupted.

If you are not sure which reason has caused your WD My Passport external hard drive read-only on Mac, check the scenarios one by one. If you know the reason already, you can jump to the scenario that best describes your situation.

Scenario 1: Your WD My Passport hard drive is NTFS-formatted

By default, macOS can mount a Windows NTFS volume or drive in read-only mode. You can view the files saved on the NTFS-formatted partition or drive but can't make any changes to them. In addition, the WD My Passport hard drive won't let you add any files to it. To check if your WD My Passport is NTFS formatted, follow the steps:

1. Go to Finder > Applications > Utilities > Disk Utilities.
2. Click the WD My Passport (you may have changed its name) at the left sidebar. The file system information will be displayed on the right.

Note: You can also right-click the disk icon at the desktop and choose 'Get Info' to check the file system information.

After having confirmed that the WD My Passport is formatted with NTFS, many people will choose to convert NTFS to APFS (for macOS Catalina, Mojave and High Sierra) or reformat the WD My Passport hard drive to make the WD external hard drive compatible with Mac. In fact, installing an NTFS for Mac driver is a much easier way.

Solution: Install an NTFS for Mac driver to make WD My Passport writable
