> Is their a pending Growmail fix for the OS 10.6.7 Update that just came out. It seems to automatically update Mail to 4.5 and then disables Growmail. I have no idea how to get it working again.
If Mail has moved GrowlMail.mailbundle to:
Bundles (Disabled)
and if your Mail folder is in the standard location:
~/Library/Mail
then, after replacing <username> with your short username in three places and quitting Mail, you can copy and paste the following into a Terminal window. It will update the UUIDs in GrowlMail.mailbundle and then move the bundle to the Bundles folder from Bundles (Disabled).
newMsgUUID=$(defaults read /System/Library/Frameworks/Message.framework/Resources/Info PluginCompatibilityUUID);
defaults write /Users/<username>/Library/Mail/Bundles\ \(Disabled\)/GrowlMail.mailbundle/Contents/Info SupportedPluginCompatibilityUUIDs -array-add "$newMailUUID";
defaults write /Users/<username>/Library/Mail/Bundles\ \(Disabled\)/GrowlMail.mailbundle/Contents/Info SupportedPluginCompatibilityUUIDs -array-add "$newMsgUUID";
mv /Users/<username>/Library/Mail/Bundles\ \(Disabled\)/GrowlMail.mailbundle ~/Library/Mail/Bundles
The Growl developers have not endorsed this solution, it is merely a rogue solution from someone who also appreciates having GrowlMail working after an OS update. I also take no responsibility of this wipes clean your hard drive and all the other hard drives in your neighborhood, though it worked perfectly for me.
Good luck.
