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.
64-bit games for Mac: The future of Mac gaming. The removal of 32-bit support caught many by surprise. Many saw it as an aggressive move that hurt both consumers and developers alike and were quick to call out Apple. Apple’s decision could be debated at length, but the move to 64-bit was a necessary move. No, there are not 32 bit intel i series processors. They can run 32 bit code though, and 32 bit OSes if you need them to, so maybe some people see them for sale with a 32 bit OS and assume its only a 32 bit processor, but its not, and you can easily just load a 64 bit OS.
Microsoft word 10.9 4. 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. Apple classic games.
If you get an alert about a 32-bit app
You will see one of these alerts when attempting to open a 32-bit app:

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. Install el capitan from dmg.
For all 32-bit apps, please contact the developer of the app to learn whether an updated version of their software is available or planned.
Macbook Pro 64-bit Or 32-bit
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!
