If you're running OS X Yosemite and above, you can use the new "sysadminctl" command to easily create users from the command line.

sudo sysadminctl -addUser keith -password mypassword

This is  a neat website that allows you to select the apps you want then it generates a bash script so you can download it via the command line.

Some users still feel the need to use Office 2011 and have been having a problem with Word and other apps quitting on launch. Rebuilding the database, trashing preferences, cleaning cache didn’t solve.

The solution for Word and Excel quitting on launch is to turn off Error Reporting.  

You can turn Error Reporting off by navigating to /Library/Application Support/Microsoft/MERP2.0/Error Reporting

Launch Error reporting. In the application dropdown menu, select Preferences.  Uncheck Enable Microsoft Error Reporting.

Changes will not take effect until you relaunch your Microsoft applications.
