It includes all the bundled apps which are part of macOS, even Chess.app, which prevents you from restoring them from a backup, or removing unwanted apps to free up disk space.
Outside /System, SIP protection is more patchy.
It is often very laborious to modify them to work properly, and you will be best off finding a version ported to work on recent versions of macOS with SIP, or use one of the package and installation management systems for Sierra. If you try running old or non-macOS installers, you may well find that they fail because they try to write tools or scripts to protected folders. The major hidden folders /bin, /sbin, and /usr are protected, but a key area within those which is unprotected is /usr/local, which is where user-installed tools must now be kept. Where nf lists a folder with a space as the first character on that line, that folder is protected if there is a non-space character at the start of the line, then that location is not protected.įor example, although almost everything in /System is protected by SIP, an exception is made for /System/Library/Caches, which is widely used to write cache files. Where ‘restricted’ means that they are protected by SIP. Which returns entries 4 root wheel restricted 136 27 Mar 20:01 38 root wheel restricted,hidden 1292 27 Mar 20:01 bin You can look it up in nf, or you can list it in Terminal using There are two reliable ways of discovering whether a file or folder comes within SIP’s protection.
#GUTENPRINT MAC HIGH SIERRA PASSWORD#
The only protection standing between such attacks and the system is a password which will allow them to escalate privileges to become root. They can replace system files and take the whole system over. On a normal Unix system, malware or an intruder which gains root access has free reign to wreak havoc. It’s also why you can’t tamper with files or folders in /System/Library, and why some old third-party extensions and customisation tools no longer work. This is why you now cannot trash the apps that Apple bundles in macOS, not even Text Edit. Since it was introduced in OS X 10.11 El Capitan, and even more so in Sierra, Apple has changed that model by implementing another level above root – this is System Integrity Protection (SIP). Gain root access to a Unix system, and you own it you are at the top of the tree of permissions and privileges. In the Unix model of life, there is one superuser: root.
