An application program, more commonly and simply known as an application, lets you open, modify or create documents that are used in the real world. A utility is a different kind of application, usually performing special tasks or dealing with particular problems on your computer.

Applications and Operating Systems

All modern Mac OS applications are designed for Mac OS X, which is itself based on the Unix operating system. Older versions of the system, such as Mac OS 9.x, are generically known as the Classic Mac OS and the applications that work in them known as Classic applications.

Carbon and Cocoa

A Carbonized application, which can often be used in pre-OS X systems as well, employs a reduced set of application programming interfaces (APIs) known as Carbon, as built into Mac OS X. These programs support some Mac OS X features but not others: they can’t, for example, always exploit the abilities of Quartz, as used for creating anti-aliased text.


Applications in Mac OS X consist of either a single file or are up of several files stored inside an application program package (APP), both of which have a filename extension of .app.

When you double-click on a package the Carbon or Cocoa application that it contains is launched.

Installing an Application

Applications for Mac OS X are often supplied in Apple’s own disc image format or as an installer application, although some arrive as a Unix archive of the .tar, .gz or .tgz variety.

Disc Images

A Mac OS X application can be provided as a disk image file, which is identified by a .dmg filename extension. You can simply click on such a file and a ‘disk’ will magically appear on your desktop: you can then run the installer application or drag the required files from this disk onto your drive.

Using an Installer Application

Some software is supplied by means of an installer application. This kind of program, when launched, places the new software and its support files onto your hard disk in the appropriate places. Since things can often go horribly wrong, you should always make a copy of the installation software before starting. And if you’re really nervous you can also back up all your other files as well.

There are several types of installer application, the most common being InstallerVISE (MindVision) and StuffIt Installer Maker (Aladdin Systems), as well as Apple’s own Installer application.

Running an installer can be risky, especially if it blindly add files to your drive that your version of the Mac OS doesn’t like, or it replaces a later version of a file with an outdated document.

Some installers let you specify the drive or folder onto which the installation is to be made. Once the installation is complete, the appropriate folder should appear at the required location, hopefully complete with the application, documentation and support files. Some installers also place extra files in various other locations. Generally speaking, it’s best to avoid renaming any of these files.

Copy Protection

The most common protection schemes involve passwords and registration numbers. In some instances the registration or authentication process is done online or over the telephone. The activation of software may employ random numbers or, much worse, numbers derived from components in your computer. Once activated, you can usually make a specified number of installations, although this doesn’t work with machine-based activation if you buy a new computer. In addition, some applications require an annual authentication. As a rule, steer clear of software that needs machine-based activation.

Application Types

Mac OS X applications can be divided into three basic types:-

Standard Application

This is the kind of application you’re most familiar with. It lets you edit existing material or create something of your own, which you can save as a document. Larger applications frequently require support files as well, some of which may be kept at various other locations.

Information Provider

This type of application automatically updates one or more data files whenever changes are made. The files are usually in the same folder as the application.

Document Viewer

This kind of application lets you double-click on a particular type of document and read its contents. Nothing is gained by launching the application on its own. Programs of this type include Adobe Reader (Adobe) and Palm Reader (Palm), as well as Web browsers, such as Internet Explorer (Microsoft) and Netscape (Netscape Communications Corp) and Safari (Apple).

Application Support Files

Major applications often come with support files that are put in their correct locations by an installer application. Such an installer usually creates a folder for these files inside the application’s own folder or package, and sometimes in other locations. Common varieties of support file include:-


This frequently comes in one of the forms listed below. The information, or material generated by the application itself, can usually be reached via the application’s Help menu.

TextEdit Files

These come in .txt (plain text) or .rtf (Rich Text Format styled text) varieties, as well as in .rtfd packages, the latter containing both .rtf files and .tiff images.

Portable Document File (PDF)

You can open this type of file using Preview (Apple) or Adobe Reader (Adobe).

Web Pages (HTML)

These .html or .htm files, which can also appear under the Help menu or in the Help Center window, can be viewed using the system’s help mechanism or your Web browser.

If possible, don’t delete, relocate or rename documentation files, as this can cause things to go astray.


Many applications provide HTML files, usually of the Help Viewer variety, or other kinds of documents that can be reached from the Help menu when the application is active.

In many Carbon and Cocoa applications, the HTML files that provide the help information are buried deep within the .app package of the application itself. Here’s the path to the help file for PandoCalendar (Panda Systems):-​Contents/Resources/​PandoCalendar Help/​PandoCalendar Help.html

Things get even more complicated with applications that support more than one language, as in Toast Titanium (Roxio):-

Toast​Contents/Resources/​English.lproj/Toast Help/​Toast Help.htm

Similarly, general information about your computer can be found at the following location:-


where is also a package.


Preferences files contain the overall settings for an application. They are normally kept in /Library/​Preferences/ (for all users) or in ~/Library/​Preferences/ (for the current user), the latter being at at the top level of the user’s home folder.


A plug-in, which is sometimes known as an extension, can be used to add extra features to one or more applications. Different programs use different forms of plug-in: QuarkXpress, for example, uses a type known as an Xtension.

Plug-ins are usually stored in a designated folder alongside the application itself, although you may initially be asked for a location for the plug-ins, which is memorised for future use.

Software Review

The list below includes includes various software elements that can enhance your Mac OS X experience. The author hasn’t included some major applications, such as those produced by Adobe or Microsoft, since these products already have sufficient publicity.

Special applications are given a rating of between * and *****, although no marks are shown for programs that haven’t been checked. + indicates software usually supplied a part of Mac OS X. The latter may be supplied on a Developer Tools CD-ROM or provided as an installer in your /Applications/Installers folder, often as DeveloperTools.pkg. The software that makes up the Developer Tools suite is also known as XCode Tools in Mac OS 10.3 (Panther) and later systems.

Activity Monitor (Apple) +

This utility, supplied with Mac OS X 10.3, supersedes the Process Monitor and CPU Monitor applications used in older systems. It shows a list of the active application processes and the amount of processor time used by each one.

Address Book (Apple) +

This program works with Mail and other Mac OS X applications, saving each address as a vCard.

You can easily add images for your existing contacts. First, create the TIFF picture files, naming each one to match the contact’s e-mail address, so that, for example, the image for fred_bloggs​ is named fred_bloggs​ Now put all the image files into a new folder called People and place that in a new folder called Images. The latter should then be dragged into the /Library folder (for all users) or ~/Library folder (for the current user), as appropriate.

Acrobat Distiller (Adobe) *

This creates Portable Document Format (PDF) files that can be viewed on virtually any kind of computer. To see them on a Mac you’ll need the Preview application, which is provided with Mac OS X, although those involved in publishing may prefer to use Adobe Reader, formerly known as Acrobat Reader.

AirPort Admin Utility (Apple) +

AirPort Setup Assistant (Apple) +

Two utilities that can be used to set up your AirPort (Wi-Fi) communications. Note that the second application doesn’t have to be used to set up the software version of a Base Station.

AppleScript Studio (Apple) +

Supplied with the system, this collection of software lets you create AppleScript-based applications. It includes Project Builder, Interface Builder and Script Editor.

AppleWorks (Apple) *****

Formerly ClarisWorks, this application can be successfully used for word processing, spreadsheet, databases, drawing and painting. Note that the Claris XTND System and its communications mode, as provided in older Classic Mac OS versions of the application, aren’t available in Mac OS X.

Applet Launcher (Apple) +

For launching Java applets.

AudioMIDI Setup (Apple) +

A utility for setting up the Core MIDI and Core Audio features that are built into Mac OS X.


A free utility for dealing with files, similar to Super Get Info (see below) but not quite as elegant.

A powerful text editor with extensive options, including support for HTML creation. Particularly suitable for programmers or anyone who needs to work on really big text files.

Bluetooth File Exchange (Apple) +

A utility for transferring data to and from any wireless devices that use Bluetooth technology.

Calculator (Apple) +

This latest version of Apple’s simple calculator has gained several new features.

Classic (Apple) +

Lets you run older applications designed for Mac OS 9.x and earlier systems. However, some programs of this kind don’t work in Classic, requiring you to restart in Mac OS 9.x, assuming you have an older machine where this be possible.

You should also be aware that many Mac OS 9.x drivers, extensions and control panels don’t work from within Classic. However, many older applications seem to run faster in this environment, despite the assertion that Classic is limited to a total memory allocation of only 128 MB.

The original Classic files installed by the Mac OS X Installer are located at:-

/System/Library/​CoreServices/​Classic​Contents/​Resources/​Universal Forks/

These can be used, if required to replace any damaged or deleted system files. Note however, that this folder is invisible in Mac OS X 10.3 or higher, although you can get to it in any case by selecting Go To Folder in the Finder.

Cocktail (Kristofer Szymanski)

A multi-purpose utility that, amongst other things, deletes corrupt cache files, forces the Trash to empty, makes invisible items visible and runs maintenance scripts.

DigitalColor Meter (Apple) +***

Provides numerical values for colours that are displayed on your computer screen.

Directory Access (Apple) +

Lets you set up login authentication, directory and network functions.

Disk Copy (Apple) +

This application is replaced by the Disk Utility application in Mac OS X 10.3 or higher (see below). It allows you to copy disks or store disk images on your hard disk.

In older versions of Mac OS X that don’t include the FileVault security system or a modern version of Disk Utility, you can use Disk Copy to create an encrypted disk image of a folder. Simply drag the folder onto Disk Copy, select AES-128 from the Encryption menu in the Image Folder dialogue and click on Save. Then in the New Passphrase dialogue enter your required password (entering it again to verify it) and click on OK after checking that Remember Password (Add to Keychain) isn’t selected.

Disk Utility (Apple) +***

Supplied with Mac OS X 10.3, this replaces the older Disk Copy and Software Restore applications (the latter for restoring the contents of a drive from a disc image). Disk Utility can be used to format, erase or test any type of disk or disk drive.

Disk Utility can also be used to repair the permissions on a hard disk. If this doesn’t work properly you may have to start up from your Mac OS X Installer CD and run Disk Utility from there.

The following procedure can be used to copy your Mac OS X Installer CDs:-

  1. Launch Disk Utility.
  2. Insert the Installer CD and select it in the left-hand side of Disk Utility.
  3. Click on New Image, name the file and select DVD/CD from the Image pop-up, ensuring Encryption is set to None.
  4. Click on Save and wait for the disk image to be created.
  5. Select the image, click on the Burn button and then insert a blank CD.

Disk Utility can also create disk images of encrypted folders or files. First, click on the New Image icon, enter a name and set a location for the new disk image file. Then set Size to the required size, set Format to Read/Write Disk Image and set Encryption to AES-128. Next, you’ll have to enter a password, but don’t select Remember Password. Disk Utility then creates the image file and mounts it as a disk on the desktop. You can then copy the required folders or files onto this ‘disk’. Finally, when you’re happy with the content, you can unmount the disk and the information will be retained in encrypted form in the image file.

DiskWarrior (Alsoft)

This is application better than most for repairing damaged disks.

Display Calibrator (Apple) +

Lets you calibrate your display screen and create a matching ColorSync colour profile.

Dock (Apple) +

An integral part of Mac OS X that provides a line of icons along one edge of the screen, giving quick access to your usual applications and documents, as well as all running applications.

If you employ special software you may prefer to disable the Dock. To do this, proceed as follows:-

  1. Move the file to the Applications folder by opening the Terminal and entering the following two lines:-


    sudo mv​Applications/

  2. Add to Login Items: you have to do this for the desktop to appear at startup.
  3. Create a script containing the line tell application "Dock" to quit and add it in Login Items after the file.

DropStuff (Aladdin) ***

This application, which compresses any files that are dropped onto it, is supplied as part of the StuffIt Deluxe package and with other Aladdin products. Later versions can create StuffIt X files, with a .sitx extension, requiring a newer version of StuffIt Expander for unstuffing.

DropZip (Aladdin) ***

Any file dropped onto this application is compressed into a Zip document, which is a popular PC format. Registered users of DropStuff can also use this program.

DVD Player (Apple) +

Supplied with the Mac OS, this simple application lets you control the viewing of DVD movie discs. Recent versions also support the 5.1 form of surround sound.


A utility for copying DVD material from your hard disc onto a blank 4.7 GB DVD-Video disc with selected options. Can be particularly useful when used with DVDBackup (see below).


Lets you copy the content of a DVD onto your hard disk drive, if necessary modifying the DVD region and disabling copyright protection. You can do this if you want a backup of a disc, but only if you actually own the disc.

A free script that forces a CD or DVD out of its drive, should the eject key fail to work.

Excalibur (Medieval Ventures) *

A neat spelling checker that can be used with many applications.

FileMaker Pro (FileMaker) +

The definitive relational database application, available in various versions. Note that FileMaker 7, which supports multiple tables, uses a different file format to earlier versions. FileMaker Server also allows FileMaker Pro database solutions to be shared by groups over a network. FileMaker Server Advanced extends this to Web publishing by means of ODBC, JDBC and XML.

FileVault (Apple) +

This program automatically encrypts the data in your home directory or selected folder using the Advanced Encryption Standard (AES) and 128-bit keys. It also incorporates a Secure Erase Trash feature that overwrites unwanted material with random data. Note that some earlier versions of FileVault have been known to cause a loss of information. If you don’t want to encrypt an entire directory or prefer to avoid FileVault you can use Disk Utility to encrypt a chosen folder (see above).

Final Cut Pro (Apple)

This, the definitive application for video editing and processing, forms the centrepiece of Apple’s collection of multimedia applications, which include DVDStudio Pro, Logic Pro, Motion, Shake and Soundtrack


A command-line software management system that gives you Internet access to a huge amount of Unix software, much of which will operate in Mac OS X, especially if you have X11 for Mac OS installed (see below). The application shows lists of software packages, lets you download them and then automatically installs the required files. It also enables the fink command in Apple’s Terminal application.


This is an Aqua-based front end for Fink, as described above. During installation, you’ll be asked if you want to install the .cshrc file in your home directory, following which you should press Y followed by Return. Failing this, launch the Terminal application, enter:-

echo -n source/sw/bin/​init.csh > ~/.cshrc

and press Return.

FinkCommander’s main window shows the available applications, although some that appear in the X11 category aren’t suitable for Mac OS X, whilst further X11 software can be found in other categories. You can find out more about an item by selecting it and pressing -I, or you can download it by clicking on the appropriate button or by choosing Binary ➡ Install.

Font Book

As supplied in later versions of Mac OS X, allowing you to work on the kerning, spacing, fraction characters, swashes and other features of each of your fonts. You can also search for fonts by name or group various effects with fonts to create new styles. In addition, you can preview a font in Font Book by simply double-clicking on the font’s file.

Process Viewer (Apple) +

Provides information about all your running applications and other processes.

Property List Editor (Apple) +

This application, which is supplied with the system, lets you modify files containing a property list in XML form. These files, which normally have a filename extension of .plist, are usually found in the ~/Library/Preferences folder. Those that are invisible must be made visible first, which you can do with TinkerTool (see below) by choosing Finder ➡ Show Hidden and System Files. Remember to make a copy of the original files before modifying them.

You can normally open a file of this kind, such as ~/Library/​Preferences/​​Safari.plist by double-clicking on it. Then click on the Root triangle in the Property List Editor’s window to reveal items such as IEFavorites​WereImported (without gaps), along with a Value, such as Yes or No. If this doesn’t work, you can examine the file in a text editor, where you’ll see corresponding lines, such as:-



The following procedure lets you start up with the Terminal application instead of the Finder. First, you must open ~/Library/Preferences/​, click on the Root triangle and then on the New Child button. Now rename New Item as Finder, double-click the Value column and enter, for example, /Applications/​Utilities/​ Finally, save the file, then log out your machine and log in again.

QuicKeys X

Software Update (Apple) +

This is launched whenever you select Software Update in System Preferences. It checks for any software updates over the Internet and offers you the opportunity to install them directly into your system.

By default, the package file used for each update, which has a .pkg filename extension, isn’t kept on your computer. However, if you think you’ll need to re-install a particular update in the future, just click on the appropriate update and select Update ➡ Install and Keep Package. A copy of the original package is then placed in the /Library/Packages/ directory.

X11 for Mac OS X (Apple) +

A free package, incorporated in Mac OS X 10.3, that lets you use Unix applications based on the X11 graphics mechanism, also known as the X Window System or X, giving you access to a huge amount of software, such as the GIMP, as well as xMySQLadmin for MySQL. Apple’s offering is based on the XFree86 display server for Unix, although XDarwin is also available.

To set up the preferences, run the X11 application in your Applications folder and choose X11 ➡ Preferences. You should choose Emulate Three Button Mouse, which lets you use Option-click to actuate the right-hand button (indicated as Ctrl-Click or C-Click in X11 application menus) and -click to operate the middle button (shown as Meta-Click or M-Click in menus).

Under normal circumstances you have to click on X11 windows twice in order to activate them. To avoid this complication, run the Terminal application and enter:-

defaults write​ wm_ffm true

and then restart the X11 application.

Applications can be added to X11’s Application menu by selecting Applications ➡ Customise, entering the program name in the Name box and typing into the Command field something of the form:-


where filename is the filename of the program itself, which can be determined by exploring the folder that contains it. Files downloaded using FinkCommander (see above) are located in the bin folder which is inside the sw folder.

A powerful integrated development environment (IDE) provided with Mac OS X 10.3. This lets you create applications using programming languages such as C, C++, Objective C, Java or AppleScript and includes Apple’s AppleScript Studio.

Useful system addition that provides keyboard access to a range of predefined actions.
