Fixing GrowlMail in 10.6.4 (Mail 4.3)

Update 2: Fix for 10.6.7 and Mail 4.5 Update: Fix for 10.6.5 and Mail 4.4

Another OS X release, another broken GrowlMail bundle. I did a post just like this for 10.6.2. Check it out if you want more background on why this occurs.

Easy Fix

Download a pre-patched GrowlMail.bundle and drop it in your ~/Library/Mail/Bundles/ directory¹. If you want it available to multiple users on your system, use /Library/Mail/Bundles/.

Download patched bundle

If you use this method you’re all set; no need to use the command line solution below.

Add New UUIDs to SupportedPluginCompatibilityUUIDs

If you have already had your plugins disabled by opening Mail.app you’ll need to look in ~/Library/Mail (or /Library/Mail if you installed globally) and move the files back to the active bundles directory. They’ll typically be in Bundles (Disabled), so quit Mail, find them, and move them back into the proper directory.

If you have a local installation:

defaults write ~/Library/Mail/Bundles/GrowlMail.mailbundle/Contents/Info SupportedPluginCompatibilityUUIDs -array-add "E71BD599-351A-42C5-9B63-EA5C47F7CE8E"
defaults write ~/Library/Mail/Bundles/GrowlMail.mailbundle/Contents/Info SupportedPluginCompatibilityUUIDs -array-add "B842F7D0-4D81-4DDF-A672-129CA5B32D57"

Global installation:

defaults write /Library/Mail/Bundles/GrowlMail.mailbundle/Contents/Info SupportedPluginCompatibilityUUIDs -array-add "E71BD599-351A-42C5-9B63-EA5C47F7CE8E"
defaults write /Library/Mail/Bundles/GrowlMail.mailbundle/Contents/Info SupportedPluginCompatibilityUUIDs -array-add "B842F7D0-4D81-4DDF-A672-129CA5B32D57"
