Initial Checks
Experiencing issues with your Seagate external hard drive being read-only on a Mac can be frustrating. Before delving into complex solutions, it’s crucial to perform some initial checks. These steps can often resolve the problem quickly and save time.
Verify Connections
First, ensure all connections are secure. Check the USB cable and port. Sometimes, a loose connection can cause read-only errors. Try using a different USB port on your Mac. If available, use another USB cable to rule out cable issues.
Check Compatibility
Next, confirm that your Seagate external hard drive is compatible with your Mac. Some drives are formatted for Windows and may need reformatting. Check the drive’s format by right-clicking on the drive icon and selecting “Get Info.” If the format is NTFS, your Mac will only read the drive. You’ll need to reformat the drive to a compatible format like exFAT or HFS+.
Make sure your Mac’s operating system is up to date. Compatibility issues can arise from outdated software. Go to “System Preferences,” then “Software Update” to check for updates.
