What method were you using for the update? And what version of macOS are you presently running? If the update failed with both System Settings and Recovery, try using Terminal to download the updater.

Go to /Applications/Utilities/Terminal.app and launch the app. At the prompt, type in

softwareupdate --list-full-installers

and press return.

You should be presented with a list of all the software updates available for your Mac. At the top of the list, you should see, hopefully,

* Title: macOS Sequoia, Version: 15.2, Size: 14921025KiB, Build: 24C101, Deferred: NO

If this is the case, make a note of the version number (in this example, “15.2”). Then type in this command,

sudo softwareupdate --fetch-full-installer --full-installer-version 15.2

or whatever version is available at the top of the list. Press return and type in your admin password. The download should start, listing the % amount completed. When finished, quit terminal. Open your Applications folder and you should see the file

Install macOS Sequoia.app

or any other version that you downloaded. Important: make a copy of this file to another location outside of the Applications folder. Make sure your backup(s) are up-to-date, with Time Machine, I hope. Reboot, ideally in Safe Mode. Open your Applications folder and start the installer file. There you go.
