I have a Snow Leopard OS X 10.6.8 and I cannot download apps. When I try to, it says 'this requires a 64-bit processor' (or something like that) and my processor is 32-bit. Does this mean that I'll never be able to download apps on my Mac? Is there a way to change the processor to 64-bit?

  • Which Mac (year and model) are you using ?

    No, you won't be able to "change" your processor to 64-bits. Sep 23, 2014 at 9:57
  • So I won't ever be able to download apps onto my mac?

    You will not be able to install 64-bit apps, but 32-bit apps are available for a lot of stuff. Which applications are you looking at?

  • To my best knowledge, only the first (early 2006) model macbooks have a core duo processor. This processor is 32-bit. Every model after this one is core 2 duo or better and has a 64-bit processor. Check your model: (Apple top right, about this mac) Sep 23, 2014 at 11:11

If your Mac allows you to replace the CPU then you could possibly buy a 64-bit processor and upgrade just that one part. Without changing that there's no practical way to run a 64-bit application on a 32-bit machine.

In the short term you'll have to find applications to download that running 32-bit environments or replace/upgrade your Mac.
