1.3b1 works in Leopard :) Hooray.

Unfortunately the fix only restores notification -- the ability to delete an incoming e-mail from the notification screen doesn't work....that was a key feature for me. I wish I hadn't upgraded to Leopard -- its 300 so-called features don't make up for the loss of Mail.appetizer. I'm not joking.

I got the fix gribskov talked about to work. Just follow those directions exactly!

Tips from the web :

A workaround was posted to the Mail.appetizer mailing list to use it under 10.5 :

1. Ensure that Mail.app is not running.

2. Launch Terminal and enter these two commands:

defaults write com.apple.mail EnableBundles 1
defaults write com.apple.mail BundleCompatibilityVersion 3

3. Move the Mail.appetizer bundle from the folder ~/Library/Mail/Bundles (Disabled) back to ~/Library/Mail/Bundles.

4. Launch Mail.app -- all should be well again.

Don't work for me, have you try this ?

Not compatible with leopard unfortunately.

I was considering using Mail Badger, but found this tool to be much nicer. Plus, it doesn't ask for administrative access to install. :)

I pray that the author updates Mail.appetizer for Leopard when it's launched. It's at the top of my "must have" list.

So ... perfect. If it were to fade in, it would be MORE perfect, but this plugin is already superb, makes me proud to own a mac!

so simple. i've used this once, and now i can't go on without it.

awesome stuff !
