Enablers, Installers, and Apple Extras Chapter 5 Enablers, Installers, and Apple Extras IN THIS CHAPTER: I The other crud in your System Folder: Enablers, System Updates, and more I Details on the automatic System Folder subfolders I A few words about the System file I Apple Extras I The Installer nobody knows That handful of control panels, extensions, and DAs described in the preced- ing two chapters doesn’t completely explain why a System 7.5 System Folder can consume 30MB of your hard drive — 80MB or more if you have, for example, a Language Kit or most of System 7.6’s goodies installed. Your Mac comes with a lot of other fascinating software, too — and the flood doesn’t stop: Every few months, Apple releases some Updater or other, which you’re supposed to know about, get, and install. Your Mac even comes with some software the Installer doesn’t install; those additional programs get left behind on the original System software disks, or dumped into an unex- plained folder on your hard drive called Apple Extras. All of it is worth know- ing about. 181 182 Part I: System Software Revealed THE SYSTEM FOLDER FOLDERS System 7 greatly reduced the cluttered, no-nested-folders setup of System 6. System 7 introduced a set of standard folders within the System Folder (see Figure 5-1): one each for Extensions (INITs), Control Panels, Preferences, Fonts (in System 7.1 and later), Apple Menu Items, PrintMonitor Documents, Startup Items, Shutdown Items (System 7.5), and Launcher Items (System 7.5). Depending on your model and System version, you may also have folders that collect things such as Speakable Items and Control Strip Modules. Figure 5-1 The basic System Folder folders. As you probably know, you’re not expected to place each System Folder- bound icon into the appropriate subfolder manually. When you drop a font, sound, control panel, desk accessory, keyboard layout, or extension icon on top of the System Folder icon, the Mac automatically dumps it into the cor- rect subfolder (and it tells you so, as shown in Figure 5-2). And by the way — we’re sick of reading that this only works if you drop the incoming items onto a closed System Folder icon. It makes no difference whatsoever whether the System Folder icon is open or closed, just so you drop the stuff on the icon. In fact, you can even drop a whole group of System Folder items of mixed types — even a folder containing them — onto the System Folder. All of the items still get stashed where they belong. In any of the System Folder’s placement proposals, you’re welcome to decline the suggestion shown in Figure 5-2 by Figure 5-2 clicking Cancel. If you want to place the item The System 7 System Folder has some drag-and-drop brains. somewhere other than the proposed folder, however, you can’t do it by dropping it onto the System Folder icon. First, you must open the System Folder into a window and then drag the icon into place. Here, then, folder by folder, are the System Folder folders. Chapter 5: Enablers, Installers, and Apple Extras 183 Apple Menu Items folder TRUE FACT QUOTE FROM HISTORY Beginning in System 7, Apple programmers hit upon the clever idea of using a menu that’s been on your screen for “A fully loaded System Folder years — the Apple (Ú) menu — as an ever-present file can easily weigh in at 200K, launcher.

After you know about the relationship between this special folder and your Ú menu, you’ll discover that the System 7 Ú menu is one of the operating system’s most useful and well-designed features. See Chapter 3 for more on Apple Menu Items and desk accessories. Control Panels folder Today’s control panels, as noted in Chapter 4, are increasingly more like indi- vidual, double-clickable programs than mere tiles of a central control panel, as they were in the bygone days of System 6. Actually, as mentioned in Chapter 4, most control panels don’t even have to be on your computer — they can live perfectly comfortably on some backup disk, or in another folder of your choosing, until you want to change one of your settings. You can open a control panel just like a double-clickable program, no matter where it is. Chapter 4 contains more information about control panels than you’ll ever want to know. Control Panels (Disabled) See “Extensions (Disabled) folder.” Control Strip Modules folder This folder is required for the glorious Control Strip found on PowerBook laptops (beginning with the 500 series) and any Mac running System 7.5.3 or 184 Part I: System Software Revealed TRUE FACT later. (If you don’t have the Control Strip, as described THE FOLDER THAT WASN’T in the previous chapter, use your System 7.5.3-or-later Installer and use the Custom Install option.) Any “tile” System 7 was supposed to include one on the Control Strip has a corresponding icon in this more special System Folder subfolder: the Help folder.The Help folder was folder. designed to be another anti-clutter repository — it was supposed to be Desktop PrintMonitor documents where all your programs stored their Help files.A Help file contains all the on- See “PrintMonitor documents,”later in this chapter. screen information that appears when you use a program’s Balloon Help,Apple Guide,or any other online help Extensions folder mechanism.

Instead of modifying the exten- (and spelling and translator) files. sions, they simply move the extensions — into a folder Aldus,Quark,Microsoft,and other companies use a similar tactic. Chapter 5: Enablers, Installers, and Apple Extras 185 they create themselves, called Extensions (Disabled). This method has two advantages: First, you can restore an extension simply by dragging it back into the Extensions folder yourself. Second, the file itself isn’t changed, so your virus-checker program won’t go shrieking bloody murder. You’ll also see Control Panels (Disabled) and, sometimes, System Folder (Disabled) folders. They’re created by those same extension-managing pro- grams, this time to handle control panels and items loose in the System Folder, respectively. Fonts folder This Fonts folder, introduced in System 7.1, is a sweet idea, too long in com- ing. In all previous versions of the System, you installed fonts into the System file itself (into the little suitcase icon inside the System folder).

  • Device Manager 1
    CHAPTER 1 Device Manager 1 This chapter describes how your application can use the Device Manager to transfer information into and out of a Macintosh computer. The Device Manager controls the 1 exchange of information between applications and hardware devices. Manager Device This chapter provides a brief introduction to devices and device drivers (the programs that control devices) and then explains how you can use the Device Manager functions to ■ open, close, and exchange information with device drivers ■ write your own device driver that can communicate with the Device Manager ■ provide a user interface for your device driver by making it a Chooser extension or desk accessory. You should read the sections “About the Device Manager” and “Using the Device Manager” if your application needs to use the Device Manager to communicate with a device driver. Applications often communicate with the Device Manager indirectly, by calling functions of other managers (for example, the File Manager) that use the Device Manager. However, sometimes applications must call Device Manager functions directly. The sections “Writing a Device Driver,” “Writing a Chooser-Compatible Device Driver,” and “Writing a Desk Accessory,” provide information you’ll need if you are writing your own device driver. If you writing a device driver, you should understand how memory is organized and allocated in Macintosh computers. See Inside Macintosh: Memory, for this information. You should also be familiar with resources and how the system searches resource files. You can find this information in the chapter “Resource Manager” in Inside Macintosh: More Macintosh Toolbox. If your device driver is to perform background tasks, you’ll need to understand how processes are scheduled.

  • 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.

  • IM: F: Introduction to Files
    CHAPTER 1 Introduction to File Management 1 This chapter is a general introduction to file management on Macintosh computers. It explains the basic structure of Macintosh files and the hierarchical file system (HFS) used 1 with Macintosh computers, and it shows how you can use the services provided by the Introduction to File Management Standard File Package, the File Manager, the Finder, and other system software components to create, open, update, and close files. You should read this chapter if your application implements the commands typically found in an application’s File menu—except for printing commands and the Quit command, which are described elsewhere. This chapter describes how to ■ create a new file ■ open an existing file ■ close a file ■ save a document’s data in a file ■ save a document’s data in a file under a new name ■ revert to the last saved version of a file ■ create and read a preferences file Depending on the requirements of your application, you may be able to accomplish all your file-related operations by following the instructions given in this chapter. If your application has more specialized file management needs, you’ll need to read some or all of the remaining chapters in this book. This chapter assumes that your application is running in an environment in which the routines that accept file system specification records (defined by the FSSpec data type) are available. File system specification records, introduced in system software version 7.0, simplify the identification of objects in the file system. Your development environment may provide “glue” that allows you to call those routines in earlier system software versions.

In other words, is there a number N, such that if I have N files in a folder, and I try to Create file number N+1, I'll get some error? ___ In general, the number of files that can be put in an HFS directory is unlimited; there isn't any point at which you'll receive an error from Create, because new file description records can almost always be created. The only way you can get a disk full error back from Create is if the catalog file needs to grow to add your new record and the disk is full, but this should be extremely rare; even when the disk is full, there's generally room to create dozens of files or folders before the catalog file will need to be enlarged, as it's grown in relatively large chunks.
