What System Integrity Protection Does and Why You Might Disable It

System Integrity Protection (SIP) is a macOS security feature that prevents even administrator accounts from modifying certain system files and processes. It runs at a level deeper than your user account — even if someone gains your password, SIP stops them from altering core operating system components. Apple turned it on by default starting with OS X El Capitan in 2015.

You may need to disable SIP if you are installing certain development tools, running older software that conflicts with SIP restrictions, or making deep system modifications that legitimate work requires. Some professional audio software, virtualization tools, and kernel extensions cannot run with SIP active. The tradeoff is real: disabling SIP removes a significant security boundary, so you should re-enable it once your task is complete.

Disabling SIP requires restarting your Mac into Recovery Mode, where the operating system itself is not fully loaded. This is intentional — you cannot disable SIP from within normal macOS because SIP protects itself.

Key Takeaways

  • System Integrity Protection must be disabled from Recovery Mode, not from your normal desktop, because SIP protects its own settings.
  • The process involves restarting your Mac, holding Command-R to enter Recovery Mode, opening Terminal, and typing a single command.
  • After you disable SIP and complete your task, you should restart into Recovery Mode again and re-enable it using the same method.
  • Some Macs with Apple Silicon chips have additional security steps that may prevent SIP from being disabled at all, depending on your security settings.

Restart Into Recovery Mode

Shut down your Mac completely. You can do this by clicking the Apple menu in the top-left corner, selecting Shut Down, and waiting for the screen to go black.

Once the Mac is off, press the power button to turn it back on. when ready hold down Command-R (the Command key and the R key together) and keep holding both keys. You will see the Apple logo appear on the screen. Continue holding Command-R until you see the macOS Utilities window — this usually takes 10 to 20 seconds. If you see your normal login screen instead, you released the keys too early; shut down and try again.

The macOS Utilities window shows several options including Restore From Time Machine Backup, Reinstall macOS, and Get Help Online. You are now in Recovery Mode, which is a separate, minimal version of macOS that runs independently of your main system.

Open Terminal and Enter the Disable Command

In the macOS Utilities window, look at the top menu bar. Click Utilities, then select Terminal from the dropdown menu. A black Terminal window will open.

Type this command exactly as shown and then press Enter:

csrutil disable

Terminal will display a message saying "System Integrity Protection status: unknown" or "Successfully disabled System Integrity Protection." If you see a message about the command not being found, you are not in Recovery Mode — restart and try again, making sure you hold Command-R during startup.

Close Terminal by clicking the red circle in the top-left corner of the window, or by typing exit and pressing Enter.

Restart Your Mac Normally

Click the Apple menu in the top-left corner and select Restart. Your Mac will restart and boot back into your normal macOS environment. This restart may take slightly longer than usual.

Once you are back at your desktop, System Integrity Protection is now disabled. You can proceed with the software installation or system modification that required SIP to be off. Check the documentation for that software to see if there are any additional steps you need to take.

Re-Enable System Integrity Protection When You Are Done

After you have completed the task that required SIP to be disabled, you should turn it back on. The security benefit of SIP is significant, and leaving it off indefinitely exposes your system to a wider range of potential threats.

Follow the same process: shut down your Mac, hold Command-R during startup to enter Recovery Mode, open Terminal from the Utilities menu, and type this command:

csrutil enable

Press Enter, close Terminal, and restart your Mac normally. System Integrity Protection will be active again.

What To Do If You Cannot Disable SIP

On newer Macs with Apple Silicon chips (M1, M2, M3 and later), additional security settings called Security Policy may prevent SIP from being disabled through Recovery Mode alone. If you try the csrutil disable command and receive an error message, your Mac may have a security policy in place.

Check your security settings by restarting into Recovery Mode again and looking for a Startup Security Utility or Security Policy option in the Utilities menu. Some Macs require you to disable certain security features (such as find Boot) before SIP can be turned off. This is a deliberate design choice by Apple to protect newer hardware. If you cannot find these options or if disabling them is not possible, your Mac's security policy may not allow SIP to be disabled, and you may need to contact the person or organization that manages your Mac's security settings.

Frequently Asked Questions

Will disabling SIP slow down my Mac?

No. SIP runs in the background and does not consume noticeable processing power or memory. You will not see a speed difference with SIP off. The tradeoff is security, not performance.

Can I disable SIP from the Terminal in normal macOS?

No. If you try to run csrutil disable from your regular desktop, Terminal will tell you that the command requires Recovery Mode. SIP protects itself, so you must restart into Recovery Mode to change its status.

What happens if I leave SIP disabled permanently?

Your Mac will work, but you lose a significant layer of protection against malware and unauthorized system modifications. It is best to re-enable SIP as soon as your task is complete. Leaving it off long-term is not recommended unless you have a specific ongoing reason.

Do I need a password to disable SIP?

You do not need to enter your account password in Recovery Mode. However, if your Mac has a firmware password set, you may be prompted for it when you restart into Recovery Mode. If you do not know the firmware password, you cannot access Recovery Mode.

Will I lose my files if I disable SIP?

No. Disabling SIP does not delete, modify, or move any of your personal files. It only changes a system-level security setting. Your documents, photos, and applications remain untouched.
