Opera
Opera is a third-party web browser for macOS that combines standard browsing with built-in privacy, messaging, and syncing features.
What is Opera?
Opera is a desktop web browser for macOS published by Opera Software AS. It is used for everyday web browsing and includes a Chromium-based rendering engine, so many websites and Chrome-compatible extensions work similarly to other modern browsers. Opera is commonly installed by users who want built-in tools such as an ad blocker, browser VPN features, sidebar integrations, and cross-device syncing. On Mac, you will usually encounter it as an app in /Applications with user data stored in the local Library folders under the Opera bundle identifier. It is not a core macOS component, and its related files are generally tied to browser profiles, settings, caches, downloads, and extension data. Users may see it set as a default browser or opened automatically when clicking web links if they have chosen it for that role.

Safety overview
Status: Mostly safe
Opera is a legitimate browser from Opera Software AS and is generally safe when downloaded from the official Opera site. As with any browser, it can store browsing history, cookies, saved passwords, downloads, and synced account data, so profile contents may include sensitive personal information.
Recommendation: Keep it if you actively use Opera or rely on its synced profile, saved logins, extensions, or default-browser setting. Remove it if you do not use it and have confirmed you do not need its browser profile data, bookmarks, or stored credentials.
