To remove all old and outdated packages in Homebrew, a package manager for MacOS, you can use the brew cleanup command.
To remove all old and outdated packages, open a terminal and enter the following command:
brew cleanup
This will remove all old and outdated packages that are no longer needed.
You can also use the --prune=X option to remove all packages that have not been updated in the last X days:
brew cleanup --prune=X
Replace X with the number of days. For example, to remove all packages that have not been updated in the last 90 days, you can use the following command:
brew cleanup --prune=90
