Choose Apple menu (little Apple icon at the top left of screen) > System Preferences, then click Software Update.
General Rule: When presented with a message to either install the updates or restart your computer to install the updates go ahead and do so. The only exception is when Tech Help has specifically communicated that you should not update.
Important Notes: Occasionally Tech Help will send out a message to check for and/or install updates to ensure everyone is up to date. If you are prompted for a login/password to update please contact us for that information if you don't have it.
If you run into any issues installing these updates please contact us.
