Firestorm
Firestorm is a desktop viewer for Second Life and OpenSim worlds, letting users explore 3D spaces, communicate, and manage in-world content.
What is Firestorm?
Firestorm is a 3D virtual world viewer for macOS that helps users access Second Life and compatible OpenSim grids from a desktop app. It is designed for residents, creators, roleplayers, educators, and community members who spend time in shared online spaces. With Firestorm, users can move through virtual environments, chat with other people, manage inventory, customize their avatar, and work with in-world objects and locations. The app is also used by land managers and merchants who need more advanced controls than a basic viewer typically provides. Firestorm is published by The Phoenix Firestorm Project, Inc. and is available for desktop platforms including Mac, making it a common choice for users who want a feature-rich alternative viewer for virtual world workflows.

Safety overview
Status: Mostly safe
Firestorm is legitimate desktop software for accessing virtual worlds. It normally needs network access and local storage for settings, chat logs, downloads, and cached world data. Because it connects to online accounts and user-created content, use the current version, download it from the official Firestorm site, and be careful with files, links, or scripted content shared by other users in-world.
Recommendation: Keep Firestorm if you use Second Life or OpenSim on this Mac. Remove it if you no longer use those services and want to free space; doing so may also remove saved settings, chat history, and cached world data tied to the app.
