Open OSM on Mac

Need to open OSM on Mac? Raw map data is a poor fit for a plain-text or generic file workflow. GeoPreview shows the coverage, structure, and key details right in Finder.

Finder selects a GIS file while GeoPreview shows the map preview and file details beside it on macOS. — Select the file in Finder and press Space to preview it right away.

What is OSM?

OSM files carry raw OpenStreetMap data. They are great for downstream tooling, but not fun to inspect as raw XML or generic files.

Fastest way to open OSM on Mac

Select the OSM file in Finder and press Space. GeoPreview turns raw map data into something you can review visually before moving into a larger OSM or GIS workflow.

Quick check before you use the file

Before you send it on or open a bigger GIS project, GeoPreview helps you confirm:

whether the dataset covers the area you expect
which layers or structures appear in the package
bounds and metadata before you load another GIS tool

GeoPreview previews a multi-layer geospatial dataset and shows metadata and JSON details beside the map. — Check layers, counts, CRS, and dataset metadata in one place.

Alternative tools

QGIS and specialized OSM tools make sense once you need deeper editing or processing. For a quick local inspection, GeoPreview is the faster first stop.

Need to convert or export it?

If you need another format, GeoPreview can handle supported exports after you confirm the coverage and structure. If export is not available for that file yet, you can still inspect it quickly in Finder.
