[1] Modern operating systems such as Windows and MacOS have built-in support for PostScript fonts, eliminating the need for Adobe's 3rd party utility.
In Macintosh operating systems prior to Mac OS X, Type 1 fonts set at other sizes would appear jagged on the monitor.
Around 2001, with Apple's Mac OS X, support for Type 1 fonts was built into the operating system using ATM Light code contributed by Adobe.
ATM installed on XP may prevent a system from entering standby – the error message indicates keyboard driver needs updating.
Adobe Type Manager was also made available for a select few PC operating systems available during the early 1990s, including NeXTSTEP,[5] DESQview,[6][7] and OS/2.
[citation needed] This incarnation of ATM, made by LaserTools was named PrimeType in the United States and Adobe Type Manager for WordPerfect elsewhere.
