Re: OS X Installation

I realise that I didn't complete my initial posting. Shortly after that post I just installed the Unix binaries and other files, and all was good.

However, I just went to install on a new Mac, running OS 10.11.5 (El Capitan) and ran into a snag, which I mention here (with fix) in case anyone else runs into it.

There is a new level of security in this OS, called System Integrity Protection , which means that the root user cannot access every directory. This means that you can't for example, install anything in /usr/bin. The two choices are to install in other directories, or over-ride the security.

I chose the latter. Here are the steps.

  • Reboot, forcing recovery mode with command-R
  • Open a terminal from the Utilities menu
  • Enter 'csrutil disable'
  • Restart

You will now have the normal root access to the machine.

It would be prudent to re-enable SIP when finished.
