Backup from MacOS BigSur 11.6.4 to 11.6.5
On my scheduled updates, I have an option to either upgrade to macOS Monterey or to update my BigSur 11.6.4 to 11.6.5.
I want to do the latter to cause minimal disruption. My question is this: is updating from 11.6.4 to 11.6.5 equivalent to upgrading the operating system, i.e. uninstalling the existing and installing a new one? If so, I assume that I will have to back up everything and reinstall a lot of software packages.
Or is the update from 11.6.4 to 11.6.5 just applying "patches" to the existing OS, rather than a full upgrade (as installing Monterey would be)
