A number of versions of the Appearance Manager are currently available. Table 2-1 specifies

Table 2-1 Appearance Manager versions

System version	Appearance Manager version	API version	gestaltAppearanceVersion
System 7.1 through Mac OS 7.6.1	must install 1.0.2 or 1.0.3	1.0.1	1.0.1
Mac OS 8	1.0 (bundled)	1.0	none
Mac OS 8.1	1.0.1 (bundled)	1.0.1	1.0.1
Mac OS 8 and Mac OS 8.1	may install 1.0.2 or 1.0.3	1.0.1	1.0.1
Mac OS 8.5	1.1 (built into the System file)	1.1	1.1.0

Version 1.0 of the Appearance Manager does not advertise its version via Gestalt ; if the gestaltAppearanceVersion selector is not present but the gestaltAppearanceAttr selector is present, you can assume version 1.0 of the API is available.

Appearance Manager 1.0.2 uses Gestalt to advertise version 1.0.1 of the API. The only differences between Appearance Manager 1.0.1 and 1.0.2 are that 1.0.2 contains extra code for backward compatibility and the ".Keyboard" font, which you can detect by calling the Font Manager function GetFNum

Appearance Manager 1.0.3 uses Gestalt to advertise version 1.0.1 of the API. The only difference between Appearance Manager 1.0.2 and 1.0.3 is that 1.0.3 no longer contains the ".Keyboard" font. In the 1.0.3 SDK, the font is delivered as a separate suitcase that should be installed into the Fonts folder. The font can still be detected with the function GetFNum .

Do not attempt to install a version of the Appearance Manager bundled with the Mac OS onto any other version of the Mac OS. Apple has not tested such configurations and does not recommend or support such configurations.
