When updating your Brave on macOS from 0.22.13 to 0.22.21 you may see this notification:
which says: “Brave.app” is an application downloaded from the Internet. Are you sure you want to open it?
You are ok to click ‘Open’ on this. Due to an issue (https://github.com/brave/browser-laptop/issues/13088) which had been included in 0.22.13, your Brave update was quarantined which caused this notification. Version 0.22.21 reverts issue 13088 but you could still see this notification the first time you launch after downloading the update.
