Have you reset the SMC first? &nbsp;Unplug the power. &nbsp;Press and hold the power button. &nbsp;Release. &nbsp;Plug in and boot. &nbsp;You should do that ahead of the PRAM reset.

Not booting to operating system

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.

Apple OS

All of Apple's hardware is produced solely by Apple Inc., who determines internal systems, designs, and prices. Apple buys certain components wholesale from third-party manufacturers. The current Mac product family uses Intel x86-64 processors. All Mac models ship with at least 1 GB RAM as standard. Current Mac computers use ATI Radeon or nVidia GeForce graphics cards and include a dual-function DVD and CD burner, called the SuperDrive. Current Apple hardware includes the iPad, iPhone, iMac, Mac Pro, Macbook, iPod and Apple TV. Discontinued hardware includes the Apple I, Apple II, and the Apple III, the Lisa, the Newton, the Quadra, Performa, Centris, Macintosh II and LC series, the Power Macintosh, iBooks and the MacBook.

Apple Hardware

Mac OS X is the desktop operating system from Apple Inc., found on Macintosh computers. OS X consists of a Mach/BSD-based kernel, operating system interfaces primarily based on FreeBSD and additional frameworks (written in C, C++ and Objective-C providing user interface and application-level services.
