Fixing TruePreview for Apple Mail 6.5

If you started Mail and it tells you that your plugin got disabled you have to move the plugin first from the disblaed folder back to the “normal” folder:

mv ~/Library/Mail/Bundles\ \(Disabled\)/TruePreview.mailbundle ~/Library/Mail/Bundles/

after this you need to figure out the new UUIDs with these two commands:

defaults read /Applications/ PluginCompatibilityUUID
defaults read /System/Library/Frameworks/Message.framework/Resources/Info.plist PluginCompatibilityUUID

These two UUIDs need to go into this file:


You can either do it with

defaults write ~/Library/Mail/Bundles/TruePreview.mailbundle/Contents/Info SupportedPluginCompatibilityUUIDs -array-add $UUID

or any other text editor.

If the bundle is installed systemwide of course you have to look into /Library instead of ~/Library.
