Question

I've seen links on the web about going into / About This Mac but it doesn't tell me information specific enough to purchase new RAM.

Here is what System Information says

Model Name: MacBook
Model Identifier:   MacBook2,1
Processor Name: Intel Core 2 Duo
Processor Speed:    2 GHz
Number Of Processors:   1
Total Number Of Cores:  2
L2 Cache:   4 MB
Memory: 1 GB
Bus Speed:  667 MHz
Boot ROM Version:   MB21.00A5.B07

On macsales I see the following text

• MacBook 1.83GHz and 2.0GHz models with Core Duo support maximum of 2.0GB memory installed

• MacBook 1.83GHz and 2.0GHz Core 2 Duo Models (May/2007) support maximum of 4.0GB memory installed, MacBook 2.0GHz Core 2 Duo ‘Santa Rosa’ (Nov/2007) models Apple Factory specification maximum 4.0GB. OWC tested to support a maximum of 6.0GB.

I bought my MacBook in November 2007 but don't know which one I got. How can I tell? And in general how can other Mac users tell so they can buy RAM from places like NewEgg and MacSales

Answer 1

(Note, the first item in your quote from OWC is “Core Duo”, not “Core 2 Duo”.)

According to apple-history.com, the ones with the 667Mhz bus are the May/2007 model.

OWC's MyOWC function says that the November/2007 MacBooks are “MacBook3,1”.

Some useful sites to identify Macs:

• apple-history.com
• ifixit.com: ID Your Mac
• OWC: MyOWC/Upgrade Center
• Apple: Support (search for “how to indetify yourModel; e.g. How to visually identify your black or white MacBook model
  • The bottom of Mac OS X versions (builds) included with Intel-based Macs includes a list of “how to identify yourModel” for Intel models
• The application Mactracker has a “This Mac” feature that seems like it might identify the Mac on which it is running.
