Students in my class are having trouble installing GPGTools

I teach an introductory information security course and the last assignment requires them to install a version of GnuPG, create a key pair, and post their public key.

I was able to install GPGTools on a test Mac OK.

Some of the students cannot get GPGTools to install.

I've attached the log file one student has submitted

    Under some (till now unknown circumstances) sometimes there seem to be major issues with the installer using OS X 10.5. Could you try to install everything again without GPG Keychain Access?

    Hey Vincent,
    I hope we can solve this 10.5 issue. It's very strange. Also, what a great idea to end an introductory security course with this part. Thanks for spreading the word and helping people learn more about security!
    all the best,

    I was finally able to reproduce this on my 10.5 system and now we can fix the problem described here (and hopefully all related issues). I'll keep you up to date.

    Hi everyone,

    I've been using GPGTools for some time and the last half-dozen or so installer bundles throw this exact same error for me under 10.5. (MacBook Pro, x86). From reading my own log file, it seems like the installer trips on Keychain Access (as in the parent poster's log) -- perhaps it is erroneously trying to install the latest (1.0b5), which requires 10.6 or higher?

    I apologize if this is a dumb question. Since not all the components in the installer are aligned in terms of minimum required system version (i.e. some are 10.5+, some are 10.6+, etc.), is the intended design to automatically install the latest available version of each component for the detected OS version? This seems like it would be the most intuitive and user-friendly way to do it (along with appropriate warnings for each component where the installer has to make such a choice), but perhaps it is infeasible for technical or practical reasons.

    In any case, I'm happy to test beta builds of the installer to provide feedback on 10.5.

    Thanks for all your hard work on this excellent project!

    Thank you for your feedback. The installer does detect the OS and only installs components that are compatible.
    Unfortunately there is currently a known issue with the installer software we're using for OS X 10.5. We've been able to identify it and wrote the developer. We'll keep you up to date.

    Best regards, Alex

    could you please follow this workflow:

    1. Download and open

    2. Run the uninstaller

    3. Run the installer

    This should fix your issue for now.

    Best regards, Alex
