SixtyFour overview

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!

Features
  • Quick Look plug-in: Quick Look displays extra info: app architectures, app platform info and bundle version
  • Single Volume Scanning: scanning a volume finds all apps even unregistered apps
  • SixtyFour Agent: it's a standalone app, which displays the bit mode of an application when launched
  • Performance Tools: the latest version of ProcessTimer is included along with other tools

I downloaded this from the email I received from MacUpdate, but when I opened it, I was told it won't work with Snow Leopard, despite the email telling me it would! Then I went to the 64 website, and it also said it will work with Snow Leopard, on the FAQ page! "SixtyFour is compatible with any G5-based PowerPC or 64-bit-capable Intel hardware running OS X Leopard, Snow Leopard, Lion, Mountain Lion or Mavericks." But on this page on MacUpdate, it now says the current version needs 10.7, however it said see links for earlier versions. that would work with Snow Leopard. Well the version shown is the same one it says only works with 10.7, 1.7.3, which does NOT work with Snow Leopard! So come on, can you not keep your versions straight? If there is a version for Snow Leopard where is it???

Initially I was interested in giving this a look until on first launch it tried to connect to download.trusteer.com. What is that about? Trying to go to the Developer's website presents one of my serious peeves - blocking viewing the website unless you click through something else to get there. Disappointing tactics in my mind and enough for me to simply trash this.

A good way to selectively enable 32bit mode for apps w/out using the Info pane. The developer helped me work out an issue when I encountered an Apple bug by setting the MAS in 32bit mode. Very responsive and thorough communication.

You are better off to max the RAM of any computer rather then waste money on some nonsense software trickery. Some programmes simply do not work well in 32 bit only because they were not programmed to run in 32 bit.

$5 for something that’s already built into OS X?

You don’t need this to switch 32-bit-capable apps from 64- to 32-bit mode — just open each app’s Get Info dialog and click the “Open in 32-bit mode” checkbox, and voilà.
