If you are having issues with your Macbook or you just want to maintain a current operating system, we strongly advise keeping your Macbook's MacOS version up to date with MacOS Mojave (MacOS version 10.14.6) or MacOS Catalina (MacOS version 10.15). MacOS Mojave and Catalina are both supported by Petaluma City Schools.


Important Note for Office for Mac 2011 Users:

Before you update to MacOS Catalina 10.15, do note that 32-bit applications such as Office for Mac 2011 will no longer function after being installed. Apple has ceased compatibility with 32-bit applications with that version of MacOS, and there is no way to restore functionality or roll back the MacOS version.


If you wish to upgrade to MacOS Catalina, you are encouraged to use alternative apps, such as the Google Suite applications (Google Docs, Sheets, Slides, etc.) or Apple's Productivity Suite (Pages, Numbers, Keynote). If you have a functional requirement to use the Office Suite, you can request the purchase and installation of an Office for Mac 2019 license for your Macbook by putting in a tech ticket.


If you wish to upgrade your MacOS version but wish to continue using Office for Mac 2011, please upgrade to MacOS Mojave and do not do any further MacOS updates.

Updating MacOS to Mojave 10.14

You can update MacOS to MacOS Mojave version 10.14, with the following steps:
  1. Download MacOS Mojave installer from the PCS Technology Google Drive here: https://drive.google.com/open?id=1bE0t-rDY7CqTfB3sSaPdGp00bzdt6ar0
  2. After the app has been downloaded, two-finger click on the installer and select, "Open".
    • If the application gives a warning that the application is from an unknown publisher, select, "Open".
    • Please note that the file will not be opened if you only double-click the file. Using the two-finger click method allows you to bypass the unknown publisher warning.
  3. Follow the steps that the program provides to update your Mac to MacOS Mojave.
  4. When the installation begins, please keep your Macbook plugged in and turned on.
    • The update takes about an hour to install, depending on the machine. 
    • Do note that you will not be able to use your Macbook while the update is installing. 
    • Do not interrupt or restart the update, or you risk bricking your device. 
  5. As soon as the update is finished, your Macbook will restart and load into the login screen.
