Installing apps is just inherently somewhat dangerous-not unlike inviting someone into your house-unless they come from the Mac App Store, where they're guaranteed to be sandboxed. In fact, a lot of these attacks don't even require root to work. On the other hand, evil apps with root permissions can wreck plenty of havoc without disabling SIP! They won't have any trouble installing bitcoin miners, reading all of your browsing history, and holding for ransom a great many (although not all!) of the files on your hard drive.

For example, an app could inject its own advertisements into Safari, or tell Microsoft Word to send all of its documents to a server in North Korea.

The danger, however, is that if I can inject my own code into any other app, other software potentially could too! You don't need to be particularly creative to imagine the mischief an evil app could cause if it could modify every other app on your machine. When an app does something I don't like-whether it's Zoom making all its windows rudely float on top, or the Dictionary app not respecting my Mac's proxy settings-I can go ahead and change it.

I've recently been learning how to swizzle methods in Objective C when SIP is off, you can use this to replace code in existing apps, which is really quite fun. Suffice to say, disabling SIP grants you a great deal of power over the way your Mac operates. Apple also made it possible to individually disable certain restrictions-for instance, running csrutil disable & csrutil enable -without debug will allow injecting code into protected processes, but still leave SIP's other protections in tact. Disabling SIP reverts your computer to the traditional UNIX behavior of letting root do whatever the heck it wants. For the first time on the Mac, Apple decided to define a set of actions which they believed no user or program-even one with root privileges-should ever be able to perform! Among these restrictions included installing kernel extensions from unidentified developers (the 'kext' protection), injecting code into projected processes, such as apps made by Apple (the 'debug' protection), and writing to certain protected system directories (the 'fs' protection).Īpple called this new set of restrictions 'System Integrity Protection', or SIP for short, and they also made it possible for advanced users to disable, by running a Terminal command from within recovery mode.

As recently as OS X 10.10 Yosemite, once you gave an app your root/administrator password, it was free to do anything it wanted, and macOS would not stand in its way.Īll of this changed with the release of macOS El Capitan in 2015. MacOS, being itself a UNIX operating system, also behaved this way for many years. If you've ever been told not to run programs as root unless absolutely necessary, this is why. There is basically nothing the OS will not allow a root user to do, whether it's rewriting system files, adding code to other processes, adding code to the kernel, you name it.

On a traditional UNIX system-including many major platforms still in use today, such as Debian-any user or process with 'root' privileges is considered to have absolute control over a machine.
