How to fix can't rename external hard drives on Mac
Now, it's time to learn how to fix the issue of not being able to rename the external hard drive on a Mac. You can apply the following methods until the issue gets solved.
Check the drive's file system
If the drive is formatted with a file system not supported by macOS, you can't directly rename the external hard drive on a Mac. You can check it via Get Info or in Disk Utility. APFS format and Mac OS Extended format are exclusive to macOS; exFAT and FAT32 are also compatible with macOS, but NTFS is read-only on Mac.
If the file system is NTFS, you can only read it, not write it by default. If it is an empty drive or there is no important data on it, you can directly format the external hard drive on Mac to get rid of the incompatibility. Otherwise, you need to enable NTFS write on Mac in multiple ways.
Among them, the NTFS driver for Mac - iBoysoft NTFS for Mac is the easiest way to mount the drive in read-write mode. It supports macOS Monterey, Sonoma, and even the latest macOS Sequoia. With this professional tool, your NTFS volume will be automatically mounted in read-write mode. Try it for free now!
