Learn how to disable Apple’s new System Integrity Protection (‘SIP’) ‘csrutil’ introduced with Mac OS X 10.11 El Capitan. Due to improved OS security, you must disable the System Integrity Protection, also called “rootless”, for installing certain apps, e.g. OpenPlex or OpenPlex Lite, or devices, e.g. mobile broadband modems like Huawei E3372 or Huawei K3765-HV.
System Integrity Protection is a security feature in OS X that protects the system shipped by Apple. By protecting access to system locations and restricting runtime attachment to system processes, this security policy guards against compromise — whether accidental or by malicious code.
OS X applies this security policy to every process running on the system, regardless of whether it’s running with administrative privileges or running unsandboxed. System Integrity Protection is activated by default, but can be easily disabled.
Here comes the fix, but be aware that you’re loosing security! Re-activate it after Installation!
How to disable System Integrity Protection ‘csrutil’
Go through the following steps:
- Boot up Mac OS X 10.11 El Capitan in Recovery Mode: To start your computer from Recovery, restart your Mac and hold down the ‘Command‘ and ‘R‘ keys at startup.
- Open ‘Terminal’.
- Use the csrutil command as follows: ‘csrutil disable‘.
- Check the success of disabling ‘csrutil’: Type ‘csrutil status’ in Terminal
Note: After installing you can re-activate “csrutil” again: ‘csrutil enable’ in terminal (recovery mode)
Disabling Apple’s new System Integrity Protection ‘csrutil’, also called “rootless”, introduced with Mac OS X 10.11 El Capitan is easily down by booting into recovery mode and executing the command ‘csrutil disable’ in terminal.
