Remember that in APFS, volumes within the same Container share free space, so you don’t have to worry about managing free space between them. This is changing with macOS 10.15 Catalina: when you install that, a new read-only volume is created and all those system files and folders are stored on that, set apart from Applications, your top-level Library folder, and user Home folders. Since El Capitan, Apple has steadily increased SIP’s coverage to include all its bundled apps and tools, but even in Mojave, they remain on the same volume as the rest of your startup folders, including the main Applications folder and user Home folders. The only way that a user can circumvent this is by turning SIP off when booted into Recovery mode (or from a bootable macOS installer) and using the csrutil command from there. SIP took all those system files out of reach of even the root user (consequently being referred to as rootless): using a combination of the nf file stored in /System/Library/Sandbox and the extended attribute, the contents of most system folders came under SIP’s protection. For once any malicious software gained access to the system, that Mac was doomed.īefore El Capitan, the only thing standing between system files and an attacker was the need to gain root privileges. Sometimes it was put down to disk errors, other times to an out-of-control extension or app, but we never wanted to think that it might have been deliberate. In earlier days of Mac OS X, it wasn’t uncommon for key system files to become damaged or corrupted. I hope in this article to convince you that it’s never safe to turn it off, and that Catalina makes that even more important with its new read-only system volume. Introduced relatively recently in El Capitan (2015), you’ll find various recommendations that to fix problems with macOS or even with some apps, you should turn SIP off first. Now, it’s slightly more involved with El Capitan.System Integrity Protection – SIP – is one of the primary mechanisms which macOS uses to protect itself.
