MUDFLAPPER I tested every single last password organizer for the Mac over the last few months, and Steel came out on top. I was leaning towards Wallet because of it's snazzy interface and icons, but there were just too many hiccups. I got all excited when Waterfall said they were going to ad dotMac/iDisk syncing so I could have one password database that I could get to from any Mac with a copy of Wallet. Turns out, they only added an import/export feature to your iDisk--a complete waste of time. I want it to just WORK. Like a Mac.
Steel, on the other hand, has been rock-solid since day one. It doesn't directly support dotMac syncing, but I've found a nifty workaround. Just save your database to a folder on your iDisk, and set the prefs to open that database automatically when launching Steel. Then, do the same with your copy at work or on your MacBook, make sure you sync your iDisk after saving your Steel database and BAM!--you're all set.
Anyway, if you're looking for the best password organizer for OSX, this is probably it.
