The "Pro" version contains Read/Write mode already while the free version has this as in-app purchase. Please try the free version first to see if it is compatible with your server.

Faster than the native Finder WebDAV mount!
Mount your cloud storage as a local directory in Finder. Access your files without syncing.
Shows up as a network drive in Finder and in your file system.
This software works internally as a local proxy, improving the communication between macOS and the WebDAV server for a more performant experience.

* Compatible with generic WebDAV protocol
* Compatible with ownCloud, Nextcloud
* Compatible with NAS storages (e.g. Synology, QNAP, ...) (TCP port forwarding required)
* Compatible with certain Sharepoint & Office365 setups, e-mail us for help.

Let us know if your WebDAV-speaking server software is compatible, if not we we will try to get it to work.

Contact us if there are any issues instead of giving a bad review, we will try to help -> ocsmount@woboq.com  :-)
