MacOS

macOS (formerly Mac OS X and OS X) is a Unix-based operating system developed by Apple for its Macintosh line of computers. iOS is the mobile counterpart to macOS.

OpenStreetMap.org

The most basic way to use OpenStreetMap on your Mac is to open https://www.openstreetmap.org/ in a Web browser such as Safari. The iD editor embedded on the website supports basic editing of OpenStreetMap, but you may find a desktop editor to be much more convenient for more advanced editing, such as imports.

OpenStreetMap applications

The following applications rely on OpenStreetMap for core functionality, so they’re good ways to use OpenStreetMap on your Mac.

Viewing maps

These applications focus on viewing various OpenStreetMap-based maps. Some of them also allow you to cache maps for offline usage.

Editing the map

In addition to the Web editors, the following editors can be installed as Mac applications:

JOSM - Java OpenStreetMap Editor. See JOSM/Mac for mac specific notes. Very uncommon user interface, most known Mac shortcuts won’t work with JOSM.
Merkaartor
Potlatch 3

Working with GPS tracks

Using these applications, you can convert and upload your GPS tracks to OpenStreetMap to help you add features to the map.

BT747 - software to interact with GPS loggers, displays tracks on top of OSM.
GpsMaster
GpsPrune - Shows tracks on top of OSM maps and allows editing of the points, as well as converting between formats.
GPXSee - GPX, TCX, FIT, KML, IGC and NMEA viewer and analyzer with various OSM-based map sources.
JGPSTrackEdit
Maps4Mac and offline browser for OSM maps with GPS support.
Mkgmap - Converts OSM data into maps that can be loaded onto Garmin GPS devices. Requires Java 1.5.
MyTracks
RouteConverter
RubiTrack - Designed for organizing and tracking your sports activity. Import from several Garmin devices and iPhone. Can export GPX files. Version 1.x still uses Google Maps for tracking. Since Version 2.0 OSM Data can be also viewed.
Vectorial Map

Recording GPS tracks

Main article: Recording GPS tracks

These applications allow you to record your movement as GPS tracks:

Trip planning

Applications using OpenStreetMap

These applications also use OpenStreetMap in some fashion:

iPhoto can be converted to use OSM in place of Google Maps
QGIS
TrailRunner - Route planning software for many sport acitivities like running, biking or hiking. Exports routes to your iPod or cellphone. TrailRunner actually is donationware.

Utilities for contributors

Gmapibuilder
GPSBabel - Tool for converting various data formats to the .GPX format.
gpsies.com, online converter and route portal, converts also Garmin TCX / CRS files to GPX. Submission to OpenStreetMap is possible.
LoadMyTracks – Loads and sends data to GPS Devices. Support for several Garmin (USB and serial), Globalsat, Lowrence, Magellan (USB and serial), Timex, TomTom and Sony devices. GPS and KML export.
RubiTrack Support direct import from Garmin (including TCX). Also has embedded GPSBabel for other formats. Can export GPX. Currently doesn't use OSM as source of maps (just Google), but developers say that OSM will be later.
OsmAndMapCreator
