every time I try to edit a log in, it quits

@ross1009: I'm sorry for the trouble! 1Password 3 was developed in 2009 and supports Snow Leopard and Lion, so it really isn't compatible with modern versions of macOS; it doesn't know anything about those, since it predates them by many years.

A better option would be 1Password 6, which fully supports Yosemite, El Capitan, and Sierra (and modern browsers). You can use your existing license to get upgrade pricing, or you may also want to consider a 1Password subscription, since it will give you access to all of the apps and do away with licenses and sync configuration altogether — you simply login to your account to authorize a device and access your data:

I hope this helps. Let me know if you have any other questions! :)
