How to mount WebDav filesystem on Mac?

In (at least) 10.9 and 10.10, mounting via WebDAV via the command line isn't easy -- the mount_webdav command does not work the way it is documented and fails silently leaving an empty mount point while the interactive version (-i) of the command works as expected. The non-interactive version files (specifically storing and retrieving of the login/password).

Here is a solution: https://github.com/childrss/webdav

The correct way to mount a WebDAV-enabled server directory in OS X is like the example you mentioned works. The reason it's asking for a username and password is because you've specified the -i argument, which denotes Interactive mode (you are prompted for the username and password).

To mount a webdav for a certain user you would use like this:

mount_webdav https://webdav.yandex.ru/username/ /Volumes/temp/

If you don't want to be prompted for the username and password then you can store the user credentials in your keychain.

see Apple's MOUNT_WEBDAV man page for more information.

You can also use something like ExpanDrive that has a graphical interface and helps you set up and maintain the webDAV mount. Faster, too, and has some extra features.
