Myth: turning off System Integrity Protection makes your Mac faster — via Apple
MythNeeds adminmacOS 14 Sonoma and later
Some 'tuning' guides tell you to disable SIP from Recovery to speed things up or to allow deep tweaks. SIP is what keeps critical system locations read-only so malware can't modify them. Switching it off strips that protection, and there's no established general speed benefit in return.
What to do instead
- Leave SIP on. Check it with
csrutil status; it should say enabled. - If a tool insists you disable SIP, look for an alternative that doesn't. If you turned it off in the past, start up in macOS Recovery, open Terminal and run
csrutil enable, then restart. - For real speed problems, check Activity Monitor for runaway apps and trim login and background items.
Apple's platform security guide describes SIP as on by default and restricting critical file system locations to read-only. On Intel Macs, turning it off removes protection for every partition on the drive.
