From the developer:
SixtyFour, a Memory Optimizer for Mac, boosts your old Mac's performance!
Apps running in 32-bit mode take up far less memory. If your Mac is older, or short on RAM, SixtyFour can help you reduce memory usage. SixtyFour facilitates the setting of a preference to force a 64-bit app to open in 32-bit mode. Opening a 64-bit app in 32-bit mode, reduces its memory usage by at least 10% and commonly as much as 50%.
