FIX: Operation not permitted as root in OS X Terminal

Switch Off

Switch OffWhen running commands in El Capitan OS X terminal, even as root  you may be greated with a rather unhelpful error message of ‘Operation not permitted’. In fact, this isn’t an error message at all – it’s part of an OS X El Capitan feature called System Integrity Protection.

The following is a description from the Apple website:

System Integrity Protection is a security technology in OS X El Capitan that’s designed to help prevent potentially malicious software from modifying protected files and folders on your Mac.

In OS X, the “root” user account previously had no permission restrictions and could access any system folder or application on your Mac. Software gained root-level access when you entered your administrator name and password to install it and could then modify or overwrite any system file or application.

System Integrity Protection restricts the root account and limits the actions that the root user can perform on protected parts of OS X.

 In order to switch off the System Integrity Protection, you firstly need to boot your Mac from the built in recovery partition, to do this follow the steps below;
  1. Power off your Mac
  2. Press and hold CMD + R on your Mac keyboard
  3. From the Utilities menu, select Terminal
  4. Copy and paste or type in the following:

    csrutil disable
    reboot

Once El Capitan has finished booting back up, you should be able to perform your advanced file manipulation without any more operation not permitted messages.

It is worth bearing in mind, if you leave this switched off you’re leaving your Mac vunerable to accidental or malicious system level file changes, which could result in it needing a complete reinstall or worse. So unless you are a confident advanced user, it would be worth repeating the steps above but replacing disable with enable.

How to screen share Yosemite screens using iMessage

OS X has included the ability to remotely screen share using a VNC style server for some time now. However, a new feature ‘hidden’ in Yosemite iMessage application is the ability to request a screen share via an iMessage conversation! If you initiate an iMessage conversation with another Yosemite user who is also using iMessage, you can use a built it request facility to view to recipients screen. The ability to share your screen originally appeared within iChat, though required an AIM, Gmail, Jabber or Yahoo account.

Once your recipient has responded to your iMessage request, click on the details link in the top right hand corner of the chat window. This will expand a second box, with the option to FaceTime, Video Call or screen share. Clicking on the Screen Share option will then pop up an additional menu offering to send a request to screen share. The recipient will then receive a popup “Allow [your name] to control my screen”. Should the recipient accept your request the screen share should commence.

iMessage Screen Share

 

This does come with some caveats:

  1. Both users must be using Yosemite or above.
  2. Both users must have an Apple ID
  3. Both users must be signed into Apple ID in the iCloud preferences pain in System Preferences

OS X 10.10.4 BETA 6 Released to BETA testers

OS-X-Yosemite-LogoOS X 10.10.4 BETA 6 build 14E36b has been released to all those who are currently registered on the public BETA test program (or who have a Apple Developer account) 10.10.4 focusing on fixing some of the bugs reported in 10.10.3. Most importantly replacing discoveryd networking daemon with the mDNSResponder as seen in Snow Leopard. Discoveryd has been at the forefront of many a complaint of Yosemite users due to its instability.

There’s currently no news on when 10.10.4 will be released as an update to the general public. However, this isn’t unusual for incremental OS X updates. Normally the BETA’s spend a couple of weeks in ‘testing’ before being released.

OS X 10.10.4 BETA 6 is available to download using the normal App Store route, or by logging into the Apple Developer Portal.
