so is it a intel core duo or intel core duo 2?


Answer:

It could any be a Core Duo or Core 2 Duo, depending on when you bought it. If it's only a few months aged or practically brand new after it has a Core 2 Duo, if it be one of the first MacBooks on the market after it has a Core Duo.



Both the Core Duo and Core 2 Duo are dual core processors, the difference between the two are the following:



The Core Duo is a 32-bit dual core processor, the Core 2 Duo is a 64-bit dual core processor, also, the Core Duo have 2MB of L2 cache where the Core 2 Duo have 4MB of L2 cache (I'm not looking this up, that's from memory but I'm fairly lasting of that). If that helps you distinguish at adjectives what your system is telling you great... if... I really don't know.



Go to the Apple Menu > About this Mac and hit the More Information button and select your processor from the list, it should inform you all that information and more, hopefully, you will be capable of tell from within.



I would think the About This Mac menu would hold the processor model and type listed such as Core 2 Duo at 1.83GHz (or anything you have).



The person below suggested CPUz which is adjectives well and accurate, if you were running Windows. My presumption is that you are running OSX within which case... CPUz will not work as it is a Windows single application.
Try googling "Cpuz" download the software if possible and it should narrate you what you want to know about your processor and more.
