Hi everone, I was a bit annoyed when I realized I couldn't open Notifications using a gesture with my Magic Mouse. Well, I found a solution! First, you have to go to System Prefs > Keyboard > Mission Control and set up a keyboard combination for Notification Center. Then, you have to download MagicPrefs and set up your desired gesture to the keyboard gesture used for Notification Center. If that's done, you'll be able to open your Notification Center with e.g. 'swiping' your Apple logo to the left on a Magic Mouse. I hope this was useful!
