Technical Support / Re: Can`t Open it,by Mac OS X El Capitan(10.11)

I realize it has been forever since this was posted, but I just found the solution the other day. I ran into this post while researching, so I think it is valuable.

http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x/

In case that link ever dies, here are the steps listed to solve the issue.

Reboot the Mac and hold down Command + R keys simultaneously after you hear the startup chime, this will boot OS X into Recovery Mode
When the “OS X Utilities” screen appears, pull down the ‘Utilities’ menu at the top of the screen instead, and choose “Terminal”
Type the following command into the terminal then hit return:

Code: [Select]

csrutil disable; reboot
You’ll see a message saying that System Integrity Protection has been disabled and the Mac needs to restart for changes to take effect, and the Mac will then reboot itself automatically, just let it boot up as normal
You can also issue the command by itself without the automatic reboot like so:

Code: [Select]

csrutil disable
