MacOS – way to hide the unread count badge in Mountain Lion’s Mail.app

Google finds an example of what is, I think, disabling bounces for all Dock icons (not Terminal alone):

• Annoying infinite bounces of an icon on alert!!!

  defaults write com.apple.dock no-bouncing -bool TRUE

However, that may be not the solution in this case. Puzzling me:

The domain/default pair of (/Users/gjp22/Library/Preferences/com.apple.dock.plist, no-bouncing) does not exist

— nothing relating to no-bouncing my preference file, and I can run for example

tail -f -n 50 /private/var/log/system.log

— then bring something other than Terminal to foreground, watch things added to the log and in my case:

• lines added to the background window do not cause any bounce, do not cause any count to appear in the Dock icon.

Setting Server to login.icq.com and Port to 5190, unchecking SSL in Server Settings tab should help.

Add:

Enter only the first eight characters of your password, leaving off any extras. This consistently worked for me. I use OSX 10.9 Mavericks and Messages.

Some have had results leaving the last character off their password.
