    “On an innovative system like the Macintosh, programs don’t look quite the way they do on other systems. For example, instead of carrying out a sequence of steps in a predetermined order, your program is driven primarily by user actions (such as clicking and typing) whose order cannot be predicted.” —Inside Macintosh, Volume I, page I-4^b4a

    “Macs have many advantages: ease of use, integration of OS and hardware, reliability, overall lower cost of ownership over the life of the machine, and, of course, style.” —Why Monopolies Are Bad, by Jeff Adkins^w77

     “That Macintosh computers have so many advantages over PCs running Windows 95 should come as no surprise. While Microsoft has spent years trying to imitate the interface and duplicate the features pioneered on the Macintosh in the 1980s, Apple has taken the Macintosh to the next generation of personal computing. This next generation of personal computing, based on RISC processors and component software, means that Macintosh computers bring you more advanced features than PCs running Windows 95, and that those features are easier to use on Macintosh systems.

    A 10-year head start is only one reason why Macintosh computers have the edge on PCs running Windows 95. The other reason is that Apple is the only major personal computer company to craft both the hardware and operating system software—together. That makes it easier for Macintosh users to start using new features.” — Apple Computer^w49

organization of Macintosh operating system

Inside Macintosh, Volume I, page I-10^b4b

    “The routines available for use in Macintosh programs are divided according to function, into what are in most cases called “managers” of the feature they support. … Most are part of either the Operating System or the User Interface Toolbox and are in the Macintosh ROM.
    “The Operating System is at the lowest level; it does basic tasks such as input and putput, memory management, and interrupt handling. The User Interface Toolbox is a level above the Operating System; it helps you implement the standard Macintosh user interface in your application. The Toolbox calls the Operating System to do low-level operations. …
    “RAM-based software is available as well. In most cases this software performs specialized operations (such as floating-point arithmetic) that aren’t integral to the user interface but may be useful to some applications.” —Inside Macintosh, Volume I, page I-9^b4b

    “The Macintosh User Interface Toolbox provides a simple means of constructing application programs that conform to the standard Macintosh user interface. By offering a common set of routines that every application calls to implement the user interface, the Toolbox not only ensures familiarity and consistency for the user but also helps reduce the application’s code size and development time. At the same time, it allows a great deal of flexibility: An application can use its own code instead of a Toolbox call wherever appropriate, and can define its own types of windows, menus, controls, and desk accessories.

    “Figure 2 [below] shows the various parts of the Toolbox in rough order of their relative level. There are many interconnections between these parts; the higher ones often call those at the lower levels.” —Inside Macintosh, Volume I, page I-9^b4b

    “To keep the data of an application separate from its code, making the data easier to modify and easier to share among applications, the [Macintosh User Interface] Toolbox includes the Resource Manager. The Resource Manager lets you, for example, store menus separetly from your code so that they can be edited or translated without requiring recompilation of the code. It also allows you to get standard data, such as the I-beam pointer for inserting text, from a shared system file. When you call other parts of the Toolbox that need access to the data, they call the Resource Manager. Although most applications never need to call the Resource Manager directly, an understanding of the concepts behind it is essential because they’re basic to so many other operations.” —Inside Macintosh, Volume I, page I-9^b4b

    “Graphics are an important part of every Macintosh application. All graphic operations on the Macintosh are performed by QuickDraw. To draw something on the screen, you’ll often call one of the other parts of the [Macintosh User Interface] Toolbox, but it will in turn call QuickDraw. You’ll also call QuickDraw directly, usually to draw inside a window, or just to set up constructs like rectangles that you’ll need when making other Toolbox calls. QuickDraw’s underlying concepts, like those of the Resource Manager, are important for you to understand.” —Inside Macintosh, Volume I, page I-11^b4b

    “Graphics include text as well as pictures. To draw text, QuickDraw calls the Font Manager, which does the background work necessary to make a variety of character fonts available in various sizes and styles. Unless your application includes a font menu, you need to know only a minimal amount about the Font Manager.” —Inside Macintosh, Volume I, page I-11^b4b

    “An application decides what to do from moment to moment by examining input from the user in the form of mouse and keyboard actions. It learns of such actions by repeatedly calling the Toolbox Event Manager (which in turn calls another, lower-level Event Manager in the Operating System). The Toolbox Event Manager also reports occurences within the application that may require a response, such as when a window that was overlapped becomes exposed and needs to be redrawn.” —Inside Macintosh, Volume I, page I-11^b4b

    “All information presented by a standard Macintosh application appears in windows. [NOTE: information also can appear in the menu bar and can be audio.] To create windows, activate them, move them, resize them, or close them, you’ll call the Window Manager It keeps track of overlapping windows, so you can manipulate windows without concern for how they overlap. For example, the Window Manager tells the Toolbox Event Manager when to inform your application that a window has to be redrawn. Also, when the user presses the mouse button, you call the Window Manager to learn which part of which window it was pressed in, or whether it was pressed in the menu bar or a desk accessory.” —Inside Macintosh, Volume I, page I-11^b4b

    “Any window may contain controls, such as buttons, check boxes, and scroll bars. You can create and manipulate controls with the Control Manager. When you learn from the Window Manager that the user pressed the mouse button inside a window containing controls, you call the Control Manager to find out which control it was pressed in, if any.” —Inside Macintosh, Volume I, page I-11^b4b

    “A common place for the user to press the mouse button is, of course, in the menu bar. You set up menus in the menu bar by calling the Menu Manager. When the user gives a commadn, either from a menu with the mouse or from the leyboard with the Command key, you call the Menu Manager to find out which command was given.” —Inside Macintosh, Volume I, page I-12^b4b

    “To accept text typed by the user and allow the standard editing capabilities, including cutting and pasting text within a document via the Clipboard, your application should call TextEdit. TextEdit also handles basic formatting sych as word wraparound and justification. You can use it just to display text if you like.” —Inside Macintosh, Volume I, page I-12^b4b

    “When an application needs more information from the user about a command, it presents a dialog box. In case of errors or potentially dangerous situations, it alerts the user with a box containing a message or with sound from the Macintosh’s speakers (or both). To create and present dialogs and alerts, and find out the user’s responses to them, you call the Dialog Manager.” —Inside Macintosh, Volume I, page I-12^b4b

    “Every Macintosh application should support the use of desk accessories. The user opens desk accessories through the Apple menu, which you set up by calling the Menu Manager. When you learn that the user has pressed the mouse button in a desk accessory, you pass that information on to the accessory by calling the Desk Manager. The Desk Manager also includes routines that you must call to ensure that desk accessories work properly.” —Inside Macintosh, Volume I, page I-11^b4b

    “You can use TextEdit to implement the standard text editing capability of cutting and pasting via the Clipboard in your application. To allow the use of the Clipboard for cutting and pasting text or graphics between your application and another application or a desk accessory, you need to call the Scrap Manager.” —Inside Macintosh, Volume I, page I-12^b4b

    There are three types of computer users:

1. Those who use Macs
2. Those who wish they used Macs
3. Those who don’t know any better

    Its a Windows world, and Macintosh users are on the outside looking in…laughing their heads off at all the frozen computers, the anguished faces, the 911 calls to tech support…

commentary

support for older machines

    Note: Apple has decided that they are no longer going to support hardware more than one or two years old. The Macintosh is the computer of choice in academic settings because schools simply don’t have the budgets to replace their entire hardware every year or two (there are still more Apple IIs in use in schools than any other computer, with the Macintosh being second). The Macintosh used to be the only computer that had a useful lifespan of more than three years. Until recent Apple policies, the latest Macintosh operating system ran on every Macintosh made. If you disagree with this new Apple policy and believe that Apple should return to the previous policy of supporting their entire installed academic base of computers, please send a message to leadership@apple.com or .
