QGIS
QGIS is a desktop geographic information system for creating, editing, analyzing, and publishing spatial data and maps on macOS and other platforms.
What is QGIS?
QGIS is a desktop geographic information system used to work with maps, spatial data, and geospatial analysis. It helps students, researchers, GIS professionals, planners, and field teams view data layers, edit geographic features, style maps, and produce print or digital outputs. The app supports common GIS workflows such as working with vector and raster data, connecting to spatial databases and web mapping services, and building layouts for reports or publication. QGIS also includes tools for geoprocessing, attribute editing, coordinate reference system handling, and plugin-based extensions that add specialized capabilities. On macOS, users commonly install it as a full native desktop app for local mapping, analysis, and cartography work. QGIS is published by the QGIS project, an official OSGeo project.

Safety overview
Status: Safe
QGIS is legitimate GIS software used for mapping and spatial analysis. It normally needs access to files you choose to open, import, export, or save, and network access may be used when you connect to online map services, plugins, or remote spatial data sources. Those behaviors are consistent with its purpose. If you work with sensitive location or project data, review any external data sources and plugins you enable, and keep the app updated through the official QGIS site.
Recommendation: Keep QGIS if you use it for mapping, spatial analysis, or geospatial data editing. Remove it only if you no longer need its GIS tools or want to free the disk space used by the app, plugins, and project-related support files.
