MacOS security update mechanism

Ubuntu has a command line mechanism for security updates:

sudo apt update

Does MacOS have a similar command line mechanism to provide updates without a release?

Update: The scope is limited to the the operating system and I would like to understand what options are available the user has to task an update check & install. I am not aware of any pull that can be triggered from the command line. I am aware (and use) the home-brew package manager, however, I doubt it is intended for this purpose. I do keep Catalina up to date with Apple releases.

Solution 1:

softwareupdate

Software Update checks for new and updated versions of your software based on information about your computer and current software.

See softwareupdate -h and man softwareupdate for the equivalent functionality on macOS.

To install the recommended updates, issue the command:

sudo softwareupdate --install --recommended
