  • The Power Manager
    HW 24 - Little PowerBook in Slumberland Page: 1 NOTE: This Technical Note has been retired. Please see the Technical Notes page for current documentation. CONTENTS The purpose of this Note is to describe the ramifications of resting, sleeping, and The Power Manager power-saving modes in the PowerBook family of Macintosh computers, how they may References affect your application, and the appropriate Downloadables ways to defeat them, when appropriate. It also describes some nonintuitive ramifications of working with a battery-powered computer. [Oct 01 192] The Power Manager In each PowerBook is a separate processor called the Power Manager. Its function is to monitor and control the power consumption and battery charging of the system. In doing this, it turns on and off various hardware subsystems, changes or stops the CPU's clock speed, watches the battery voltage, and, when charging, sets the bulk charge or trickle charge modes of the battery charging circuit. As you can see, the power draw of the system is a dynamically changing value, depending on which subsystems are currently in use, the speed of the processor, and whether or not charger circuit power is available. The Power Manager is designed to optimize for the maximum battery life and controls the various operating modes in response to user preferences that allow the user to override or push back in time the onset of these modes. The Many Faces of the Power Manager The PowerBook 100 (just like the original portable) has four operating modes: normal, rest, sleep, and shutdown. The PowerBook 140 has four operating modes: normal, rest (power cycling), sleep, and shutdown.

  • Chapter 1. Origins of Mac OS X
    1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years.

  • Mac OS X: an Introduction for Support Providers
    Mac OS X: An Introduction for Support Providers Course Information Purpose of Course Mac OS X is the next-generation Macintosh operating system, utilizing a highly robust UNIX core with a brand new simplified user experience. It is the first successful attempt to provide a fully-functional graphical user experience in such an implementation without requiring the user to know or understand UNIX. This course is designed to provide a theoretical foundation for support providers seeking to provide user support for Mac OS X. It assumes the student has performed this role for Mac OS 9, and seeks to ground the student in Mac OS X using Mac OS 9 terms and concepts. Author: Robert Dorsett, manager, AppleCare Product Training & Readiness. Module Length: 2 hours Audience: Phone support, Apple Solutions Experts, Service Providers. Prerequisites: Experience supporting Mac OS 9 Course map: Operating Systems 101 Mac OS 9 and Cooperative Multitasking Mac OS X: Pre-emptive Multitasking and Protected Memory.
