# Deprecated Symbols

Review unsupported symbols and their replacements.

## Overview

Overview The table below describes keys for an NSDictionary object containing information about an app. This dictionary is returned by activeApplication() and launchedApplications, and is also provided in the userInfo of NSWorkspace notifications for app launch and termination. Note that these constants are considered legacy. note: It is strongly suggested that you use the NSWorkspace class’s runningApplications method and the NSRunningApplication class to retrieve this information in apps target macOS 10.6 and later, rather than the activeApplication() and launchedApplications methods.  |   |   |   |   |   |   |
