Is there a way to find out whether an app running in our Mac is 32- or 64-bit? OK, I know that big-name apps such Office 2008 or Adobe Acrobat are 64-bit, but what about, say, aMule or Vuze? How can I tell whether such apps that reside in my disk are 32- or 64-bit?
And by the way, does running a 32-bit app in Snow Leopard produce any slowdown or instability in the overall system, or it is just the 32-bit app itself which might behave in a more inferior way but without affecting anything else beside itself?
Thanks in advance for the replies!
Apple began transitioning to 64-bit hardware and software technology for Mac over a decade ago, and all modern Macs now include powerful 64-bit processors that can run advanced 64-bit apps. These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today's Mac experience.
- Although both 32-bit and 64-bit programs can be installed on a 64-bit operating system, a 32-bit program will only be able to access up to about the first 4 gigabytes of memory (RAM). By contrast, a native 64-bit program installed on a 64-bit operating system will be able to utilize a much higher amount of memory (RAM), allowing for much larger.

Apple has been working with developers to transition their apps, and in 2018 Apple informed them that macOS Mojave would be the last version of macOS to run 32-bit apps. Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS.

When installing macOS, you may see a list of recently used apps that are 32-bit. You can review this list before deciding to continue installation. You may also see a prohibitory symbol over the icon of each 32-bit app in the Finder, letting you know that the app will not open.
