CAVE for macOS requires the **[awips-python.pkg](http://www.unidata.ucar.edu/downloads/awips2/awips-python.pkg)** package be installed in order for **derived parameters** to work.
*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](https://github.com/mrj0/jep/) must be installed in some way (it is assumed in `/Library/Python/2.7/site-packages/jep/`). You are free to install jep yourself but should know that simply to install via source code or pip requires the Oracle JDK and Xcode and its Command Line Tools. The **[awips-python.pkg](http://www.unidata.ucar.edu/downloads/awips2/awips-python.pkg)** package is provided as a workaround for this.
Writes files to **caveData** in the user's home directory.

## 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).
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.).
