| macOS
| Download and install both
[awips2-cave-17.1.1-6.dmg ](https://www.unidata.ucar.edu/downloads/awips2/awips2-cave-17.1.1-6.dmg)
[awips-python.pkg ](https://www.unidata.ucar.edu/downloads/awips2/awips-python.pkg)
Writes and syncs files to ~/Library/caveData.
**awips-python.pkg** is not a prerequisite, and CAVE will still run and display data without it, but to use any derived parameter functions such as wind barbs/arrows and grid parameters on various vertical coordinates, jep must be installed in some way (it is assumed in /Library/Python/2.7/site-packages/jep/)

## AWIPS Data in the Cloud
Unidata and XSEDE Jetstream have partnered to offer a EDEX data server in the cloud, open to the Unidata university community. Select the server in the Connectivity Preferences dialog, or enter **`edex-cloud.unidata.ucar.edu`** (without *http://* before, or *:9581/services* after).

---
## Troubleshooting
**Localization Preferences Error**
You can reset CAVE by removing the **~/caveData** directory (on macOS **~/Library/caveData**) and then run `cave` again to connect to an EDEX server. Your local files have been removed, but if you are re-connecting to an EDEX server you have used before, the remote files will sync again to your local **~/caveData** (bundles, colormaps, etc.).
**No Images Displayed**
If you are able to load wire-frame contours but not images, [update your video driver](http://www.nvidia.com/Download/index.aspx?lang=en-us).
