Why is there a red dot on the notifications in my system preferences on my iMac?
iMac, OS X Yosemite (10.10.3)
It's just part of the icon design. It has no inherent meaning.
Unless I misunderstand the question, the red dot has just migrated a little.
See Mountain Lion for example, below.
OS X El Capitan: Use Notification Center
OS X El Capitan: Receive or stop notifications
It's a design element. Other than that, no reason.
