After downloading a recent update, I became unable to open software that came with OS X such as Safari, iTunes and the App store. When I try to open any such application, it crashes a split second after I open it and I get a message "[app name] quit unexplectedly while using the CFNetwork plug-in". Thanks in advance for any help.
MacBook Pro (Retina, Mid 2012), OS X Mavericks (10.9.5)
A Safe Mode boot deletes system caches that may help after an OS X update or upgrade.
Top left corner of your screen click the Apple > Shut Down.
After your Mac shuts down, wait 10 seconds, then press the power button.
Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator.
Once you are in Safe Mode, go back to the Apple menu. From the drop down menu click: Restart

If the above doesn't work, try looking at the hard drive level Library/Internet Plugins - if the plugin is there, move it to your Desktop, restart, and test.
Safe mode boot sorted it out, thanks.
