Macintosh software is installed and removed differently than Microsoft Windows software. Macintosh programs tend to be packages that can be uninstalled by simply dragging the application to the Trash.

Applications may create preference files that are stored in the /Home/Library/Preferences directory. The benign remnants orphaned in the Preferences folder can be removed manually to recover disk space.

• /Home/Library/Preferences

Application components may place files in the /Home/Library/Applications Support directory. These will also become orphaned if the package is removed. Delete these files to recover disk space.

• /Home/Library/Applications
• /Library/Receipts

Check for "StartupItems" and "LoginItems"

• /Library/StartupItems
• /Home/Library/StartupItems

Check for startup services

• /Library/LaunchAgents
• /Library/LaunchDaemons
• /Home/Library/LaunchAgents

Commercial software typically comes with an uninstall utility that is responsible for removing all orphaned files. The thoroughness of the uninstaller may vary from one package to another.

Malware does not follow these conventions. The malware developer makes effort to conceal the malware as to be installed in places which are difficult to locate and remove. Malware may place some components in common locations while installing residuals in hidden locations as to prevent removal, or to provide a backdoor for further malware to be added later.

Apple’s OS X (being Unix-based) is less vulnerable to malware and computer virii than a PC running Microsoft Windows. Yet there are still threats to the Macintosh computer.
