Developer previews and Public Betas are available. macOS Sierra (10.12 internally) is currently in development, scheduled for this Fall. The previous version of OS X is 'Yosemite' (10.10), released on October 16, 2014. The 'iPhone OS' or iOS, which powers the iPhone, iPod touch, and iPad is a direct descendant of OS X, and shares its design and many internal frameworks. Starting with 10.7 'Lion', Mac OS X is now referred to simply as 'OS X'. AMD is not currently officially supported. Since 10.6, PowerPC support is non-existent/dropped, and Mac OS X is currently designed for Mac computers with Intel 32-bit (x86) and Intel 64-bit (x86_64) architectures. Intel (x86) support started with 10.4.4 Tiger, and was built as a universal release for both PowerPC/x86 with 10.5 Leopard, which finally dropped all G3 support. The first six releases (10.0.0-10.5.8) were designed for the PowerPC architecture, adding 64-bit PowerPC support as an additional platform for the G5 in 10.3 Panther. Mac OS X has been built for three different architectures and four platforms during its release cycle to date. While underlying components of OS X are free/open source software, the top layers, such as the Aqua UI, are proprietary Darwin packages can be downloaded and compiled from the Apple Open Source website to make a bootable OS. It shares none of the 'Classic' Mac OS design, and is completely rewritten and uses Next frameworks, a hybrid XNU/Mach kernel, and a BSD subsystem dubbed 'Darwin'. As mentioned by Apple, Wikipedia, and others, it is said as Mac OS 10. It is the successor to Mac OS 9, hence the X signifying both its Unix roots and the major release version number 10. MacOS (formerly Mac OS X) is an operating system for Apple Macintosh computers, first released to the public on March 24, 2001, developed by Apple.
