Mac OS 7.x-9.x
Installing PostScript, TrueType and OpenType Fonts
A PostScript font consists of a Suitcase File and a Printer File. If you have a font family, you may have one suitcase for the whole family and up to four printer files — one for each style — regular, italic, bold and bold italic. Some manufacturers also include AFM files that can be used by some old applications.
A TrueType font and an OpenType font consists of one Suitcase file.
For PostScript Type 1 fonts and for OpenType fonts with PostScript flavor (OT/PS) in all Mac OSs except for OS X, you need Adobe Type Manager (ATM) to make the fonts appear smooth when viewed or printed at all sizes.
You may install fonts by means of operating system or with the help of font management utilities. To install with font management applications like Adobe Type Manager, Suitcase or Font Reserve, please consult the product manual.
Font installation on Mac is a simple drag and drop operation.
