Mac OS X: About This Mac window provides computer serial number


You can use the About This Mac window to find your computer's serial number when started up from Mac OS X 10.1 or later.

Follow these steps:

Choose About This Mac from the Apple Menu.

Double-click the version text,
for example "Version 10.1".

Your computer's serial number now appears where the version text had been.

Note: Some earlier Mac OS X-compatible computers do not have their serial numbers stored in a way that allows this feature to work.

Lack of this feature on your computer does not indicate any software or hardware failure.
