The “Optimizing Your Mac” Notification in Mac OS X Explained
Some Mac users may see a notification alert pop-up from Mac OS X in the corner of their display with a message stating “Optimizing Your Mac – Performance and battery life may be affected until completed.” While there aren’t any additional details offered in the notification, there is a “Close” button, which will dismiss the alert.
