Transmit and Forklift are paid, we can't use finder, macfusion doesn't work... so I'm wondering...
Is there any free option left to mount an FTP on finder so that I can write files to it? Maybe using scripts or automator? Maybe fixing my issue with macfusion? I don't even know why my installed macfuse is 2.1.7 (beta) while it asks me to "update" to 2.0.3 or, if I tick "Show Beta Versions", 2.1.5! In general, it looks to me the whole thing is too unstable yet.
Last case, I'll just stick with CyberDuck. And yes, I've just tried them all except automator.
