Hi _Alvin,
Mac OS X is finally finished, with Apple confirming that it’s officially moving to macOS 11 with the newly announced Big Sur update after almost 20 years of OS X (or macOS 10.) That means that this. 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.
- The latest version of OS X that you can get running on a MacBook 4,1 (Early 2008 model) is Mac OS X 10.7.5. El Capitan will not run on the non-Aluminium 2008 models (Early or Late). I have verified this information against the Mactracker app (not affiliated with Mactracker in any way).
- MacOS Big Sur brings a new design that’s been finely tuned for the powerful features that make a Mac a Mac. Core features, such as the menu bar and Dock, take advantage of the large Mac display, with translucent backings and spacious pull-down menus.

Checking the model numer A1181, EMC 2200 it sounds like you have a white MacBook (Late 2007).
