How can I update my Mac to Mojave 10.14 so I can install Office 365?

Microsoft Office 365 requires 10.14 Mojave. If your computer needs to update from its current OS to Mojave, you can find the download here:

Note: before performing an operating system upgrade:

  • Make sure you have a backup of your important documents and pictures (use an external hard drive or Google Drive or iCloud)
  • Make sure you plan to have the time: this could take several hours and you don't want to start the process and then interrupt it!
  • Make sure your laptop is plugged in to power and will not be moved through the upgrade process.
  • Don't start this process if you're going to need your computer soon! Give yourself plenty of time. 

You can't interrupt this process once it gets started - it's not like a quick application you can install in 5 minutes!
