Apple releases so many slightly-tweaked models of their computers and other devices that it can be difficult to remember exactly which one you have, e.g., “is this an early 2008 or a late 2008 MacBook?”
This can be important when you are considering the purchase of an external accessory that requires a specific type of port to connect to your device – you cannot connect a Thunderbolt device to a Firewire port, and a device that wants USB 3.0 may not be happy with a USB 2.0 port (though the reverse is probably okay).
There’s an easy way to find out exactly how your Apple product is configured:
♦ Go to http://support.apple.com/specs/
♦ Click the Browse by Product button on the upper right.
♦ In the search field on the next page type your device’s serial number (for a Mac computer, click on the “Apple” at the top left of your desktop, Select “About This Mac”, then “More Info…” to find the serial number)
♦ The search result will be a link to the tech specs of your device.
