I found the way how to mount remote directories on Mac and noted the link in this article. But I didn't try it at that time, and do it today. It is easier than I thought.
- Install FUSE for OS X
- Install sshfs
- create mount point directory
- sshfs $user@$remote-server:$remote-dir $mount-point-directory
FUSE for OS X can be downloaded from https://github.com/osxfuse/osxfuse/downloads.
The command line tool "sshfs" can be downloaded from https://github.com/osxfuse/sshfs/downloads.
