Important
These instructions only apply if the extension of your file is exactly .agilekeychain_zip. If you have a file with a different extension (such as .agilekeychain without the “_zip” at the end), these instructions do not apply to your situation.
Select the .agilekeychain_zip file and choose File > Get Info from the menu bar.
Change the underscore (_) in the extension to a period (.). So the extension changes from .agilekeychain_zip to .agilekeychain.zip. For example,
1Password 2011-02-24 205523 (56 items).agilekeychain_zipbecomes1Password 2011-02-24 205523 (56 items).agilekeychain.zipClick Use .agilekeychain.zip when asked.
Double-click the file (now a ZIP file) to decompress it.
You should now have a usable Agile Keychain (.agilekeychain). Using the same example from above, you would end up with a file called 1Password 2011-02-24 205523 (56 items).agilekeychain which can then be opened in 1Password 4 or later.
