G Keys

Gmail supports g then (a, c, d, i, s, t) shortcuts to go to specific mailboxes. In order for the g then ... configuration to work for Archive and Flagged, you will need to configure your Favorites Bar to include these two folders. You can have other folders as well, but you must include Archive and Flagged. Your Favorites Bar should look something like the following:

If you are not familiar with the favorites bar, see the following instructions for help.

How to Install

1. Download Gapple.mailbundle.zip located in the build directory, note if your building the bundle then you don't follow this step
2. Enable Mail.app plugins: defaults write com.apple.mail EnableBundles -bool true, note you only need to do this once
3. Expand Gapple.mailbundle.zip
4. Copy Gapple.mailbundle to ~/Library/mail/bundles, note: you may have to create the bundles folder

Plugin Compatibility Error

Apple Mail requires a Plugin Compatibility UUID in order for a mailbundle to load. If you get an error regarding Gapple.mailbundle when Mail loads, it is most likely due to the UUID. To fix this, follow these steps:

1. Download the project as laid out in Setup Workspace
2. From terminal run defaults read /Applications/Mail.app/Contents/Info PluginCompatibilityUUID
3. This will print the current Mail UUID to the screen
4. It should looks something like DAF41AB7-F9AD-4273-9934-C81C74705B69
5. Copy the value to the clipboard.
6. Edit the info.plist file located in ~/Desktop/Gapple/Supporting Files
7. Add the UUID to the SupportedPluginCompatibilityUUIDs of the file
8. Save the info.plist and follow the Compile instructions

The SupportedPluginCompatibilityUUIDs section of the info.plist looks like this:

<key>SupportedPluginCompatibilityUUIDs</key>
  <array>
    <string>B61772F2-9975-4EC0-B22F-9A277C46ADD2</string>
