At NCS we use an "empowered user" model for all teacher and staff Macbooks. This means you have admin rights and one of the easiest ways to keep your computer running like a champ is to make sure you are always running your updates. Periodically you may see an email from the IT department that asks you to avoid a particular update, but for the most part regularly running updates is an excellent practice. The ones that we might ask you to avoid are large operating system changes, such as an update from 10.10 (Yosemite) to 10.11 (El Capitan) which will occur later this fall.
Updates fall into three main categories
All updates for the Apple operating system or any Apple programs can be found in the Mac App Store. When you launch this application you should be asked whether or not you want to run the updates right now. Occasionally you might be asked for the firstname.lastname@example.org password. If this happens you can find that password on this Google Doc (NCS Staff only).
Microsoft Office Updates
Word or Excel acting wonky? Try running Microsoft Office updates. When you launch Word or Excel the autoupdate feature should launch for you. If it does not you can always trigger it by clicking Help in any MS Office application.
Google Chrome Update
Have you ever noticed that your Google Chrome has three red or orange lines at the right side of the toolbar? That means it needs an update. You can complete this task by going to the Chrome Help Menu (chrome://help/). Sometimes, if you have waited too long Chrome may not update for you. If this happens, navigate to the Chrome website, download an updated version, and install the program.
