Norm 1974's solution sounds excellent, the kind thing i would want. But it seems that my OS, Mountain Lion, doesn't have those choices in the system preferences>notifications. Those choices look great. that's what i need. In mail>preferences, there's no way there to turn thise things off. I have it set to none, but they keep coming.
Oct 29, 2012 · Those little alert balloons are part of the Notifications feature of OS X 10.8, the system otherwise known as Mountain Lion. You can change their appearance or turn them off entirely, but to do so, you need to visit the preferences for Notifications.
You can change notification preferences for all events on your Google Calendar. On your computer, open Google Calendar. In the top right, click Settings Settings. On the left, click General Event settings. Under “Event settings,” you can choose to: Turn notifications on or off: Click Notifications, and select how you want to get them.
Under Personal Settings, click Notifications & Sounds. Under Message arrival, choose the settings that you want for new messages. Under Sounds, clear the check box next to each sound that you want to turn off. Tip: To preview a sound, click the Play button next to each sound option.
