Installing JOSM on Mac

We will cover here how to install JOSM on Mac using various methods.

1. Method: Install JOSM via Homebrew

  1. Open a terminal
  2. Execute
brew install --cask josm

to install

2 Method: Install JOSM using a package

Use this method if you don't have Homebrew installed, installation of Homebrew too complicated or JOSM will be your only application which you will install over Hombrew

  1. Go to https://josm.openstreetmap.de
  2. Download MacOS package (external link).
  3. Save it somewhere e.g. in your Downloads folder and execute it.

3. Method: Install JOSM as .jar

Use this method if you have Java installed, installation of Java JRE on Mac is not a problem for you or JOSM is not your only application which depends on Java.

  1. Go to https://josm.openstreetmap.de
  2. Download josm-tested.jar (external link).
  3. Save it somewhere on your disk e.g. create a Portable Apps folder on your desktop and put that file in there. This way you also maintain a good structure in using portable apps.
  4. Execute JOSM by double clicking on its file. If nothing happens over 10 seconds (depending on your hardware) that means probably you haven’t Java installed or the file association .jar not properly associated with it.
