I had problems getting MongoDB to start using launchd (my preferred method for portability) after a fresh Yosemite install. After initially suspecting the _mongo user was not being correctly created by the Macports installation script, it turned out to be a simple permissions issue.
Often I would like to access files over SFTP but without the limitations of an FTP client. For example, it’s handy to alter remote files directly in terminal as if they are local, or open them with my nice, fully fledged editor. Mucking around downloading/uploading files each time I modify them gets annoying quickly, especially with something fiddly like web development.
Fortunately SSHFS is now in MacPorts, and provides a quick solution for those on a Mac with SSH access. I could of course configure a file server but that is not always possible, particularly if you don’t have the ablity to install software on the remote machine!
