Mac users often encounter situations where external drives or partitions are designated as "Read-Only," limiting their ability to modify or create content on those drives. While this can be a protective measure to prevent accidental data loss, there are times when you need to change these drives to read-and-write mode. In this guide, we will walk you through the process of changing read-only file systems on your Mac without any cost, using built-in utilities and commands.


Part 1. What are Read-Only File Systems?


Read-only file systems are volumes or partitions on your Mac's storage media that only allow you to view the contents but prevent you from making any changes, such as adding or deleting files. This can occur due to various reasons, including file system issues or the drive being formatted in a way that restricts write access. Here are some common factors that lead to drives becoming read-only on Mac.

 

System Files: MacOS protects critical system files by making them read-only. This prevents accidental changes that could disrupt the operating system's functionality or stability.

 

User Permissions: When files are created or edited, macOS assigns permissions that control who can access, modify, or delete them. If the permissions are set to restrict write access, the file becomes read-only for certain users.

 

File Corruption: In some cases, file corruption or errors in the file system structure can lead to files becoming read-only. macOS might set files as read-only to prevent further damage to the corrupted data.

 

NTFS Drives: When using NTFS-formatted external drives (common in Windows systems), macOS may mount them as read-only by default. This is due to NTFS being a proprietary format that macOS can read but not write to without additional software.
