• Download Mac Os 10.12

When you install a Mac OS upgrade there is a risk your Mavericks system will not boot. When upgrading from 10.9.0 to 10.9.5 like I did, it will not boot. My impression (after reading different sources) is that this recovery is needed when upgrading from 10.9.0 (or 10.9.1 / 10.9.2) but not later. Those are either Mavericks Security Updates, or the Combo Updates that take the user from 10.9 to 10.9.5. The 'Install OS X Mavericks' should be on the order of 5 or 6GB in size (I do not have the exact size at the moment, but 1.5GB is way too small). If you have Snow Leopard, Lion, or Mountain Lion installed (10.6, 10.7, 10.8), upgrading to 10.9 Mavericks is as simple as heading to the Mac App Store, clicking the huge OS X Mavericks banner.

OS X Mavericks download is the 9th major release of the Mac OS X versions history. It was the most powerful operating system in 2013 for Macintosh computers. The OS X Mavericks download version 10.9.1 released in December 2013 after two months from releasing the OS X Mavericks original version. This update made a number of changes to the operating system and fixed out some issues on the previous version.
