About Outdated macOS Versions
Beginning in July 2022 devices that are enrolled i the Mac Self-Service and that run an outdated major version of macOS (as of October 2021 anything lower than macOS 10.15) will receive the following monthly reminder that their macOS is unsupported:
When the user acknowledges the alert by clicking "OK" the webbrowser will open https://devices.docs.cern.ch/devices/mac/macos_versions/.
No other action will be triggered by this alert, the installation of a supported macOS version is left entirely to the user.
We can not assure that this alert displays on all the outdated macOS versions used by CERN users.
