# [[macOS]] - System Integrity Protection (SIP) Apple moved to an immutable Operating System a few years back. This means that there's certain parts of the OS that cannot be modified under normal conditions. To make changes to this System Integrity Protection (SIP) needs to be disabled. Then changes can be made, and then in ***pretty much every use case*** SIP should be re-enabled. SIP can be checked from any state of the OS, but it requires booting into Recovery Mode to make any changes. | Action | Command | | --------- | ----------------- | | Enable | `csrutil enable` | | Disable | `csrutil disable` | | Status | `csrutil status` | | More Info | `csrutil` | # How to use it Many tutorials say you need to go into Recovery mode, disable SIP, then reboot, go into the OS make your changes, then reboot to Recovery mode, then enable sip, and then reboot, and then you're good. What I've noticed is that you can make changes as soon as SIP is disabled, then re-enable SIP, then reboot, which saves a lot of time waiting for a computer to boot. Even though computers reboot faster these days!
