Here are the direct Apple CDN download links for the Safari 16.5 update released today (2023-05-18) for macOS Monterey and Big Sur:
The Safari 16.5 update for macOS Ventura is part of the macOS Ventura 13.4 update.
Note that I have not personally tested these installers as macOS Ventura is now the minimum support version of macOS for my org.
I'd like to get SUPER all up and working and enforce Software Updates as well as Safari Updates.
Until that happens, can I make a Smart Group with Patch Reporting: Apple Safari less than: Latest Version and Computer Group member of Monterey or Big Sur, and then a single Jamf Policy targeting that smart group that runs a /usr/sbin/softwareupdate --install --safari-only --force
And would I still need to exclude computers that are 12.0 - 12.4?
