You need to download XCode 7.1 from Apple and install it. After you install it from Apple, launch XCode and agree to the license terms.

You will also need the patch shown here.

I tried but it did not work.

>> mex -setup

Warning: Xcode appears to be installed, but it has not been configured. Run "osascript -e 'do shell script "xcode-select -switch /Applications/Xcode.app" with administrator privileges'" to configure Xcode. You must be an administrator of this computer to complete this action.

Go into Applications Utilities and start Terminal . At the Terminal command line command

sudo xcode-select -switch /Applications/Xcode.app

and authenticate. Then try the mex -setup again.
