SixtyFour, a Memory Optimizer for Mac

Not all Macs are created equal. Not every Mac comes with the RAM needed to open and run a dozen RAM-hungry Mac apps.
If your Mac is older, or short on RAM, there’s a system utility to help you reduce memory usage and start up apps faster. All you need is any recent 64-bit Intel-powered Mac, or even a G5-powered PowerPC Mac.
In tough economic times some of us may have to extend the life of our Macs. Not everyone can afford the latest and greatest Mac that’s loaded with lots of app-crushing RAM.
If you want to run more apps at the same time, and, at the same time, open apps faster, but can’t upgrade to the newer, faster Macs with more RAM, this is the app for you!

SixtyFour's main aim is to improve performance of Macs with less RAM and extend the life of older Macs.

What SixtyFour does is simple. An app usually contains several versions of the code: a version intended to run on 32-bit Intel processors, another one meant for the more recent 64-bit Intel processors. This ensures that the app will run on all the platforms that support OS X. SixtyFour analyzes the apps you have installed and ignores apps that will only open in 32-bit mode or 64-bit mode, leaving only 64-bit apps that can open in 32-bit mode.
SixtyFour is simple to set up and use. When SixtyFour starts, it presents a list of 64-bit apps that can open in 32-bit mode. A selected check box indicates that the app will open in 32-bit mode and a non-selected check box indicates that the app will open in 64-bit mode. Check those 64-bit apps you want to run in 32-bit mode, and you’re good to go. Changes made in SixtyFour will be kept across reboots. It is not required to keep SixtyFour running. That's it!

Apps running in 32-bit mode on your Mac take up far less RAM.

Forcing a 64-bit app to open in 32-bit mode reduces its memory usage significantly and its startup time. Opening a 64-bit app in 32-bit mode reduces its memory usage by at least 10% and not uncommonly as much as 50%.
On Intel-based Macs the lower RAM requirements and reduced startup times are quite notable. Even on older, PowerPC-based Macs (certain G5?s only), the result is that apps use less RAM, and usually start up faster. SixtyFour works especially well with Leopard, Snow Leopard, Lion and Mountain Lion releases of OS X. That means you can keep your Mac running longer, but running better.

Expert Reviews:

"SixtyFour is one of those rare Mac apps that helps you keep your Mac longer, even when today’s apps are 64-bit and require much more RAM than Macs of just a few years ago." – Mac360

Client's Testimonials:

"Memory is king. By forcing some apps into 32-bit mode does save me more RAM for running memory-hungry applications." – Tom Tsui
"It's a very good little application, quite helpful to run those everyday applications in 32-bit mode in Lion, i.e., Safari, Mail, WebProcess, etc., to reduce memory usage. For more demanding applications, 64-bit is good." – Edgar Cabrera

System Requirements:

Intel/PPC, 64-bit processor, OS X 10.5 or later
