Download and run the DMG file. Then follow the installer instructions. Our package is not signed, so you may want to have a look at how to open apps from "unidentified developers".

How to run...

Use the 'Gaia Sky VR' shortcut in the start menu or gaiaskyvr.exe (Windows) or $ gaiasky -vr from CLI.

Getting the data

The Gaia Sky installation only contains the raw program. If you actually need to run Gaia Sky you will need to download some data (catalogs, 3D models, textures, etc.). To do so, Gaia Sky contains an integrated download manager which pops up at startup whenever no data is detected or new versions of current data packs are found. In case you need to run Gaia Sky in a machine without an internet connection, we offer direct downloads for all versions of all data packs. As a general rule of thumb, you should always get the most recent version.
