So I’ve been working on getting everything running with Snow Leopard (64 bit kernel mode) as I did with Leopard. The last remaining piece of software that was not working correctly was the GPGMail plugin. The plugin uses undocumented API’s for Mail.app and with the change over to 64 bit for all applications it seemed to have broken. I was searching around google and found someone that had updated it to work with SL (the original author does not have the time to do it), however with the 10.6.2 update it broke again. The fix was simply to add the new UUID’s that 10.6.2 changed and it worked again. As I can’t seem to find the original link, I’ve included the fixed zip file here if anyone would like to use it. All you have to do is unzip this file, then move the GPGMail.mailbundle folder to your ~/Library/Mail/Bundles directory (make sure Mail.app isn’t running first). When you start Mail.app your GPG plugin will work again and have all the options in the preferences menus. You may need to also enable bundles support for mail (if you aren’t using any plugins currently, or it’s a fresh install). To do this open a Terminal and type:
defaults write com.apple.mail EnableBundles 1
