The PowerBook VM Tuner is an extension which enhances system stability when virtual memory is used on the PowerBook 1400 with Mac OS 7.6 installed. The Tuner is required only on version 7.6 of the Mac OS.

Version 1.0 of the PowerBook VM Tuner was released on March 12, 1997, and requires Mac OS 7.6.

The Tuner is preloaded into the System Folder on the PowerBook's hard drive, but is not included in the system software installer. A user that has reinstalled Mac OS 7.6 must manually reinstall the Tuner separately.
