SixtyFour v1.5.0 MacOSX | 1.47MB

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.

Running most if not all apps in 32-bit mode on systems that have little memory available can potentially lead to an increase in overall system performance. That means you can keep your Mac running longer, but running better.

If you intend to run more apps at the same time, and, at the same time, maintain system performance, but can't upgrade to the newer, faster Macs with more RAM, this is the app for you!

Not all Macs are created equal Not every Mac comes with the RAM required to open and run a dozen memory-hungry Mac apps. Not everyone can afford the latest and greatest Mac that's loaded with lots of RAM.

Requirements

Intel, 64-bit processor

OS X 10.6 or later
