We generally recommend that you use the CloudStor sync client to access CloudStor from an Mac - however it is possible to connect your Mac to CloudStor using WebDAV through Finder. This way you can access your CloudStor files in the same way as any network share.
1. Open Finder
2. Click on Go on the menu bar at the top and select Connect to server...
3. Enter https://cloudstor.aarnet.edu.au/plus/remote.php/webdav/ into the URL field (click the + if you'd like to save it as a favourite) and click Connect
4. Enter your CloudStor username and sync password and click Connect again
5. If successful, you will be presented with your CloudStor files and folders.
