Install OS X High Sierra


All staff MacBook airs can be updated to the latest stable OS version, High Sierra. Normally the update could be downloaded from the App store but, we have cached (pre-installed) the installer to simplify the process. 

***Before you upgrade your OS, you will want to make sure your Microsoft Office is up to date.  You can find the latest update here.***

  1. Please back up important files before beginning an update.
  2. Make sure your MacBook Air is connected to a power source.
  3. Do not close your lid during this process.

***Added incentive: if you own an Apple Watch, you will be able to unlock your MacBook Air without typing in a password!***

Best practice for performing this update is to make sure the computer is plugged in and charging. You will need to have anywhere from 50-60 minutes to let the computer install the update. DO NOT restart your computer during this update process. It may appear to be frozen or unresponsive, but it is installing the update. Also, please close all open applications before beginning the update process.


To install the update, please open the Applications folder. Click the Install High Sierra button and a management action window will pop-up. Select Start now and submit, after that the update will be prepared and you will be prompted to log off and wait for it to reboot. Please DO NOT manually restart your laptop, log off and it will automate the process its self after 5 minutes have passed.



Upon reboot, you will see a screen that looks similar to the image below. It has a progress bar to indicate how much time remains. Once again, please DO NOT power down the laptop during this process.  


After it has finished the install, it will reboot and you will be able to log back in. Congratulations, you just successfully updated to OS X High Sierra.
