I didn't want to wait for an update to Growl for Mac OS X 10.6.7 (all
due respect of course to the Growl team) and if I break it, it is my
fault.
Having said that, I ran this:
defaults read /Applications/Mail.app/Contents/Info
PluginCompatibilityUUID
defaults read /System/Library/Frameworks/Message.framework/Resources/
Info PluginCompatibilityUUID
to get the UUIDs I need:
9049EF7D-5873-4F54-A447-51D722009310
1C58722D-AFBD-464E-81BB-0E05C108BE06
and then (with Mail closed) I copied GrowlMail.mailbundle from ~/
Library/Mail/Bundles (Disabled...) (the latest one) into ~/Library/
Mail/Bundles
Then I edited ~/Library/Mail/Bundles/GrowlMail.mailbundle/Contents/
Info.plist
and in the area under <key>SupportedPluginCompatibilityUUIDs</key>
I added:
<string>9049EF7D-5873-4F54-A447-51D722009310</string>
<string>1C58722D-AFBD-464E-81BB-0E05C108BE06</string>
saved the file and now Growl is once again working...
