Components of the Macintosh System Folder

The classic Macintosh system folder requires certain files and directories in order to function properly.

Core System Files

System Enablers

A system enabler file is placed in the root of the System Folder and is required on certain Macintosh models, typically when the Mac OS version is older than the hardware. A 1994 list of required system enablers can be found at Latest System Enablers List (June 1994).
