Step by step guide to upgrade the operating system on school issued Mac and Windows 10 computers.

Before You Start

Make sure your power supply is securely connected at both ends. Please be connected to a fast and reliable internet connection such as the eduroam wifi, direct ethernet in your office or your home internet.

  1. Make sure to backup your data. You can find more information at: Backing up Your Data
  2. Make sure your computer has been updated fully prior to the upgrade using the following articles from Apple and Microsoft:
    1. Updating Your Mac with Managed Software Center
    2. How to keep your Windows computer up-to-date

  3. Quit all your open applications prior to running the upgrade
  4. Know that the upgrade process could take a while. On some hardware, the upgrade may take over an hour to complete.

Updates vs. Upgrades

An update is when patches of code are released in order to fix minor stability or security issues. An upgrade is when the old operating system is replaced with the newest and supported version.

Why upgrade?

  • Security upgrades - The most important reason to upgrade systems is to patch the vulnerabilities that exist in older operating systems. Both Apple and Microsoft have changed the way they handle their older operating systems and CIT has to keep up by enforcing a new upgrade process.
  • Efficiency - Both Apple and Microsoft have made the code running their operating systems smaller and more efficient. In recent years, it's become more common to have upgrades improve a computer's performance.
  • New features - New operating systems come with new features which empower clients with the ability to do more with existing hardware.
