Is there a way of dating a mac by looking in the os. Like checking the system profile, or something?
Your Mac's serial number will reveal all. Try entering it into this website and it'll tell you the year, month and place of manufacture.
In case you don't know, you can find the serial number easily by looking in the About This Mac window lamina mentioned click twice on the version of the OS that is listed, and it'll show you the serial.
I don't know about you guys, but the idea of entering my serial number into some unaccountable site is... Reckless.
Go to http://www.apple.com/support/
In the bottom left corner, enter your serial number. Apple will tell you the model, the original date of purchase, and give you customized support, repair and registration options.
Much more useful, and safer than some random site in the Netherlands.
