turn off text notifications for alerts on mac

So Apple have decided this has to be done via the OS notification of sounds and not via Thunderbird. For the majority of users, and according to Apple, that is the correct solution. The simple fix for this bug then, is to disable and remove all notification sound options from Thunderbird, on OS X 10.8 and above, and let Notification Center deal with it. Under Sounds, clear the check box next to each sound that you want to turn off. Under Message arrival, choose the settings that you want for new messages. Now, you can use the right panel to can configure how notifications how up.

Find and select the application for which you’d like to disable notifications. Every application that uses notifications is listed here. Since OS X 10.8, display of notifications - alert banners/dialogs, badges, and notification sounds - are now the responsibility of the operating system, not the application. Under Personal Settings, click Notifications & Sounds. Head to System Preferences > Notifications, but this time pay attention to the left panel. When you go into Thunderbird > Preferences > GeneralĪlerts and default sounds can be stopped by the notification field in system installation.

However, I note that you are using MAC OS and I have heard of something similar before.
