Updating operating system on mac
While Apple previously charged users for its desktop operating system software, in October 2013 the California-based company announced that OS X Mavericks would be made available for free from the Mac App Store.
And when it comes to zero-day support, our Apple track record speaks for itself.
However, since Snow Leopard was released before Apple instituted its free desktop operating system policy, you must pay to get the upgrade from Leopard to Snow Leopard.
Snow Leopard software is available for purchase for .99 from the Apple Store.
Due to the rapid pace of advancement in computer hardware development, there is a limit to the backward compatibility of Apple’s latest operating system with certain older Mac Book Pro computers.
Here are the Mac Book Pro models that are compatible with OS X Yosemite, according to Apple’s website.For a detailed overview of the core technologies in OS X Yosemite, browse this documentation from Apple.
