1Password - RoboForm for Mac
RoboForm for Mac. It doesn't exist. But, who needs it when you have 1Password. When I switched to the Mac, like you, I searched for a Mac version of RoboForm, but Siber does not make one. Thankfully, Agile Web Solutions has given the world the perfect solution in 1Password. Upon purchasing this wonderful program, I was immediately able to import all of my RoboForm passcards and I was form-filling on my Mac in minutes! A beautiful thing.
The creators of 1Passwd have put together a lot of great documentation for their product, including a movie illustrating 1Passwd's many features and uses. Whether or not you are new to the Mac, 1Passwd is a must-have application.
