Version 1.2.5 and Mountain Lion Compatibility
If you have told Propane to store your Campfire password(s) in the keychain, the system will grant or deny access to those passwords based on the certificate used to sign each release of Propane.
The signature allows each new release of Propane to 'prove' that, even though the application is different, it's still Propane and it still should be given access to the same keychain passwords.
In order to support Mountain Lion (OSX 10.8) I've had to switch from my original certificate to a DeveloperID certificate provided by Apple.
This means that, as far as the system is concerned, version 1.2.5 is not "still Propane" because the signing certificate is different.
Upon your first launch of Propane 1.2.5, you will be prompted to allow Propane to access your keychain. The prompt looks like this:
As long as you choose "Always Allow" in the prompt, this will only happen once, although you will be prompted for each of the Campfire accounts you have registered with Propane.
Mountain Lion (OSX 10.8) includes a new security preference called Gatekeeper for controlling which downloaded applications are allowed to run on your system.
Propane 1.2.5 has been signed with an Apple Developer ID so it's compatible with Gatekeeper. However, you'll need to make sure your system's "Security & Privacy" settings allow for "Mac App Store and identified developers" as seen below:
