How to Tell if Your Mac is 64-bit Tutorial and Steps
So here we discuss the How to Tell if Your Mac is 64-bit, and after a lot of requests from our users here is a guide about How to Tell if Your Mac is 64-bit.
Wondering if your Mac is 64-bit architecture or 32-bit architecture? Well, you may not be alone. The good news is that it is quite easy to determine which CPU architecture your Mac is using.
You can focus on the Mac’s model year or the CPU architecture and processor chip itself. The most precise measure is aimed at the CPU.
Basically, every Mac released after the end of 2006 is 64-bit, which means that all modern Macs are 64-bit. Most Intel Macs are, too, with a few exceptions to the earlier Intel releases.
If you are not sure whether your Mac is 64-bit or not, the easiest way to check it is to find out what kind of processor your Mac has, and the easiest way to do that is to do the following:
How to Determine if Mac is 64-bit or 32-bit
- Open the Apple menu and click ‘About This Mac’
- Now see what it says next to “Processor” and use the following as one guide:
- Intel Core Solo – 32 bit
- Intel Core Duo – 32 bit
- Intel Core 2 Duo – 64 bit
- Intel Quad-Core Xeon – 64 bit
- Intel Core i5 – 64 bit
- Intel Core i7 – 64 bit
Basically anything newer than the “Intel Core Duo” and “Intel Core Solo” processor will be a 64-bit architecture.
What is the difference between 32-bit and 64-bit?
32-bit and 64-bit architecture are completely different, with 64-bit being a much more modern architecture that benefits from various memory and processing improvements. For a more technical explanation, Wikipedia explains the difference as follows:
A change from a 32-bit to a 64-bit architecture is a fundamental change, as most operating systems will need to be extensively modified to take advantage of the new architecture, as that software must manage the actual memory addressing hardware. Other software must also be ported to use the new features; older 32-bit software can be supported either through the 64-bit instruction set being a superset of the 32-bit instruction set, so that processors that support the 64-bit instruction set can also execute code for the 32-bit instruction set, or via software emulation, or through the actual implementation of a 32-bit processor core within the 64-bit processor, as with some Intel Itanium processors, which include an IA-32 processor core to run 32-bit x86 applications. The operating systems for those 64-bit architectures generally support both 32-bit and 64-bit applications.
