* '''Core Image''': A graphics processing API that allows programmers to leverage programmable GPUs for fast image processing for special effects and image correction tools. Some of the included Image Units are Blur, Color Blending, Generator Filters, Distortion Filters, Geometry Filters, and Halftone features.
* '''Core Data''': A data persistence API that makes it easier for developers to handle structured data in their applications. Core Data provides undo, redo, and save functions for developers without them having to write any code.
* '''Core Video''': A video graphics API that leverages Core Image to provide real-time video processing. Apple's Motion real-time video effects program takes advantage of Core Video in Tiger. Core Video lets developers easily integrate real-time video effects and processing into their applications.
* '''Core Audio''': Integrates a range of audio functionality directly into the operating system.

In addition to these APIs, Tiger introduces a new window theme, often described as 'Unified'. A variation on the standard, non-brushed metal theme used since the introduction of Mac OS X, this theme integrates the title bar and the toolbar of a window. A prominent example of an application that utilizes this theme is Mail.

Tiger is also the first version of Mac OS X to include the "Zoom" screen magnifier functionality.
