Dear Mac users,
WHAT ARE WE DOING?
macOS Mojave v10.14 is approaching its end-of-life (EOL). When EOL occurs, macOS Mojave will no longer be supported by Apple and therefore will stop receiving security updates.
Starting Friday, Oct. 22, 2021, any Mac computer running macOS Mojave (v10.14) will be blocked from accessing the Fermilab network. Fermilab-owned computers, by laboratory policy, must run vendor-supported operating systems to avoid security risks.
WHAT IS THE IMPACT TO YOU?
If your Mac is running macOS Mojave (v10.14), you must upgrade it to macOS Big Sur (v11) or Catalina (v10.15) before Friday, Oct. 22, 2021.
WHAT DO YOU NEED TO DO?
• To upgrade your Mac on your own, open the “Self Service” application and choose “macOS Big Sur” or “macOS Catalina 10.15” from the upgrade section.
• If you need assistance, please submit a Service Desk ticket to request an upgrade to macOS Big Sur (v11) or Catalina (v10.15).
• If neither macOS Big Sur nor Catalina appears in the upgrade section of the “Self Service” application, that Mac may not support upgrading.
• If you have an older Mac that can’t be upgraded, please begin planning the replacement or decommissioning of the Mac. Contact the Service Desk if you need assistance.
