Installing PostScript, OpenType, or TrueType Fonts in Mac OS X

Installing PostScript, OpenType, or TrueType Fonts in Mac OS X
Mac OS X supports PostScript Type 1, OpenType, and TrueType font formats.
If you use a font management utility to manage your fonts, follow the instructions for the utility to install and remove fonts.
Note: We recommend installing only one format - OpenType, TrueType, or PostScript - of a font. Installing two or more formats of the same font may cause problems when you try to use view, or print the font.
Installing Fonts into Mac OS X
Before installing fonts, you should close any open applications. For some applications, new fonts do not appear in the font menu if you install them while the application is open.
In the Finder, open the folder or disk that contains the fonts you want to install.
Select the font suitcases for the fonts you want to install. For PostScript Type 1 fonts, also select the printer outline files.
Drag and drop the fonts into the Fonts folder in the Library folder.Note: If you want fonts to be availabe to applications running in Classic mode, you must install fonts in Macintosh TrueType or Macintosh PostScript format into the Fonts folder inside the Classic System Folder.
Installing PostScript or TrueType Fonts in Mac OS 9.x or 8.x
Mac OS 9.x and 8.x support PostScript Type 1 and TrueType font formats.
Macintosh System 9.x allows you to open 512 suitcases at once. Macintosh System 8.x and earlier only allow you to open 128 font suitcases at one time. If you exceed these limits, not all the fonts you install will work.
If you use a font management utility to manage your fonts, follow the instructions for the utility to install and remove fonts.
Note: We recommend installing only one format - TrueType or PostScript - of a font. Installing two or more formats of the same font may cause problems when you try to use view, or print the font. To install PostScript Type 1 fonts, we recommend you use Adobe Type Manager (ATM) Deluxe or ATM Light. You can download ATM Light for free from Adobe's Web site.
