Upgrading your MacOS Version

Why upgrade?

Upgrading your Mac is recommended because it brings security, performance, and usability improvements. Let us break down these points.

Security

  • It is essential to have an up to date supported macOS, this mitigates against any security vulnerabilities on your managed device.
  • Apple cease supporting older macOS versions on a cycle by stopping any further updates and security patches. Your Mac then becomes a security risk.
  • Apple will only support the three most recent macOS Versions.
  • The Antivirus solution Sophos stops updating on older macOS versions.
  • Having an up-to-date macOS ensures the latest Safari web browser updates ensuring safer internet browsing.

Performance

  • Bug fixes for crashes, WI-FI and Bluetooth performance.
  • Application compatibility like ensuring that Microsoft Office Suite and Cisco VPN work and are supported.

Usability Improvements

  • This ensures you can use the latest and greatest features in the new macOS such as Apple Intelligence and better integration like iPhone mirroring.

How to upgrade

The normal path to upgrade is via the System Settings/General/Software Update options. If you get prompted to provide an administrator user name and password and are not able to update this way then please launch the Self Service App and look out for the upgrade policy options within Core Software.
