I downloaded after some searching the file 1Password 3.9.20 for Mac OSX 10.6.1 Snow Leopard. When i double clicked in the Downloads folder to install, 1Password 4 was listed. Now I don't know what to do because that is probably for 10.7. My mac is 8 years old and still going well with a new motherboard. I can't upgrade because my software will be lost, and probably other problems too. But I have so many websites with passwords, I need to make a move for safety. What do you suggest?
