Finally Advanced SystemCare is here on OS X as MacBooster, so we can keep our systems optimised and clean.
- William Cody Winter

A new report claims the Mac Pro was in limbo at Apple but 'constant negativity' and a poor reception of its new MacBook Pro resulted in the company deciding to double down on hardware for pro users. Better integration of hardware and software Apple makes MacBooks (hardware) as well as Mac OS (software). This is not seen of other manufacturers like Dell, HP, Lenovo etc. Which make the hardware of their computers and run Windows (which is developed by Microsoft, a software company).
