Are you encountering a read-only file system error on your Mac? There are multiple reasons for this error. This article will explain the causes of a read-only file system and provide solutions based on different situations. Read on to learn more about read-only file systems.
A Read-only file system means that users can only read the system volumes under the file system on Mac but cannot make changes to them or store data on them. This problem can be encountered in two situations:
According to the official instructions, after upgrading macOS to Catalina, the hard drive will be divided into read-only and writable parts. In the Catalina version, users cannot operate on the read-only system volume. Changes to the /root directory cannot be made from the command line using root.
You may also encounter read-only file system errors when using an external hard drive. You will not be able to write to the external drive. This is due to the fact that your drive is in Windows format (NTFS), and it cannot be freely written to and edited on a Mac. You need to change the drive to a suitable file system format to solve the NTFS for Mac read-only.
There are various situations when you encounter read-only file systems on Mac. The specific solution depends mainly on your situation. Once the specific situation is sorted out, you can solve the read-only on Mac problem using the following methods.
macOS has protection restrictions on the applications that come with it. We need to remove the protection restrictions from the computer first. Here are the steps to turn off SIP.
Step 1. Restart your computer and hold down Command+R to access the Recovery screen.
Step 2. Enter your username and password and select Disk Utility.
Step 3. Select and open Terminal in the top menu bar and enter the command: csrutil disable.
Step 4. Reboot to make the command take effect.
Note: You do not need to enter Recovery OS mode to reboot. Normal mode is sufficient. After the reboot, confirm the current SIP status using the csrutil command with the following details:
liumiaocn:~root# csrutil status
System Integrity Protection Status: disabled
This sets the SIP via csrutil.
To confirm if the problem is with the external drive format, you first need to confirm the drive's file system. You can check the external hard drive file system in Disk Utility. If it is an NTFS system, you can use Disk Utility to convert it to APFS. But your data will be deleted by using this way.
