To anybody that's running Safari 5 on Leopard or earlier and still wants to use 1Password 2.x, you should be aware that recently upgraded browsers are no longer being supported in version 2 of 1Password. For those of you who can't or won't update to Snow Leopard or 1Password 3 or both, here's how to enable 1Password 2.x support in Safari 5 (Thanks to Greg Kumparakat at CrunchGear for the original inspirational hint about using 1Password with Safari 4 beta).
How to enable 1Password 2.x in Safari 5 for Leopard:
- Close Safari
- Go to the /Applications/ folder
- Right click on 1Password.app and select 'Show Package Contents'
- Navigate to /Contents/Resources/
- Double click on SupportedBrowsers.plist. If you have Apple's development tools installed, it'll open in the Plist editor. If not, it'll open in TextEdit.
- If you're using the Plist editor, expand the 'Safari' drop-down (Just click the little arrow beside Safari).
- Look for the MaxBundleVersion key – change it to 6534.0. Save the change.
- Launch Safari 5.
As always, it is a good idea to make a backup of SupportedBrowsers.plist before messing with it.
[crarko adds: I haven't tested this one. If you run Snow Leopard you should upgrade to 1Password 3.2.1, which works with Safari 5.]
