SixtyFour is a memory optimizer and system utility for Mac OS X, its main purpose is the augmentation of overall system performance on low memory systems by reducing the memory overhead associated with apps running in 64-bit mode.
SixtyFour presents a list of 64-bit apps that can open in 32-bit mode. Apps excluded from the list are apps that will not open, apps that will only open in 32-bit mode or 64-bit mode, Java apps and unregistered apps.
SixtyFour facilitates the setting of a preference to force a 64-bit app to open in 32-bit mode. Forcing a 64-bit app to open in 32-bit mode reduces its memory usage significantly and its startup time.
SixtyFour is compatible with any G5-based PowerPC or 64-bit-capable Intel hardware running Mac OS X 10.5 Leopard, Mac OS X 10.6 Snow Leopard, Mac OS X 10.7 Lion or higher.
