Can MacFusion be used under Mountain Lion? I have bought a new MacBook Pro with Retina display which has OS X 10.8.3. I have installed MacFusion from the version on their website, but I cannot mount it, getting this error: Could not mount filesystem: Mount process has terminated unexpectedly.

Can you help me with that?
Unfortunately Macfusion no longer works, it hasn't been maintained in a long time. Newer versions were around for a while but as near as I can tell, none of them work anymore either. Your best bet is a commercial product which can mount FTP or WebDAV disks such as Transmit. For mounting disks via SSH, I believe we're out of luck.

Such is progress.
