Where do all fonts reside when using Mac or 9x?

On a Mac, fonts are primarily stored in the Fonts folder located within the Library directory, specifically at /Library/Fonts, ~/Library/Fonts for user-specific fonts, and /System/Library/Fonts for system fonts. In Windows 95/98, fonts are typically found in the C:\Windows\Fonts directory. Both operating systems allow users to install additional fonts that can be accessed by applications.
