Macs running unsupported macOS versions no longer receive security updates from Apple and many third-party developers. Additionally, Macs with an unsupported macOS version are out of compliance, putting Mason at greater risk, and will be removed from the Mason network, including VPN.

Apple supports the most current and two previous operating system versions:

• macOS 12 (Monterey)
• macOS 13 (Ventura)
• macOS 14 (Sonoma)

ITS recommends upgrading to macOS 14 (Sonoma) or macOS 13 (Ventura). If you are comfortable upgrading on your own, you may do so by selecting one of the following links to the Apple App Store:

• Upgrade to Sonoma
  • Compatible Computers
  • macOS14 (Sonoma)
• Upgrade to Ventura
  • Compatible Computers
  • macOS 13 (Ventura)
• Upgrade to Monterey
