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:

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
For WD My Passport Ultra and WD Elements, check if the hard drive is formatted with NTFS file system. 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:
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. But as you know, directly formatting WD Elements or My Passport on Mac causes data loss.
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

Scenario 2: You have read-only permission to access the WD My Passport hard drive
If your WD My Passport external hard drive is not formatted with NTFS but you have no write permission to it, it is probably because you have read-only permission to access the WD My Passport. Since your WD external hard drive is write-protected, all your write access is denied.
To know your permission to the WD My Passport, follow the steps below:
If you can see the message 'You can only read', then you will understand why you can't write to your WD My Passport drive.
Solution: Change read-only permission on the WD My Passport drive
Follow the instruction below to change permission on Mac so that you can access the WD My Passport again:
Step 1: Click on the lock icon at the right corner in the Get Info window.

Step 5: Click 'OK' when you are asked to confirm the operation.
Step 6: Click the 'Read Only' in Privilege column and select 'Read & Write'.

Scenario 3: Your WD My Passport hard drive is corrupted
If you are sure that the read-only WD My Passport is not caused by NTFS file system nor read-only permission, another possible cause might be the disk corruption. When an external drive is corrupted, people suddenly have trouble reading or/and writing to the disk. Then you will have to fix the corrupted WD My Passport external hard drive to make it writable again. We will introduce two solutions here:
