Snow Leopard, Apple’s newest operating system, is due to be released in September. Snow Leopard runs on a 64-bit kernel, and to take full-advantage of this new OS, you need a Intel-based Mac running a 64-bit processor. So how can you tell if your Intel-based Mac has a 32-bit or 64-bit processor? Follow the instructions below to find out:
1. Choose About This Mac from the Apple () menu in the upper-left menu bar, then click More Info.
2. Open the Hardware section.
3. Locate the Processor Name
4. Compare your Processor Name to information below to determine whether your Mac has a 32-bit or 64-bit processor.
Processor Name

Intel Core Duo is 32-bit
Intel Core 2 Duo is 64-bit
