How to find a serial number on a computer without an OS.

Hi!

I erased the content of my old iMac and old MBP, and I'm ready to sell them.

However, I can't find the computers' serial numbers because "About this Mac" is not accessible since the computers don't have an OS anymore.

Is there another way to find the serial numbers?

Thanks!

Chris.

Here is how to locate the serial number:

http://www.everymac.com/mac-identification/where-to-find-apple-serial-numbers-fo r-identification.html

Mac Series	Serial Location
Power Mac G3	Back
Power Mac G4	Back
Power Mac G5	Inside Access Panel
Mac Pro	Back
iMac	Bottom or Under "Foot"
eMac	Inside Optical Drive "Flap"
Mac mini	Bottom
PowerBook G3	Bottom
PowerBook G4	Inside Battery Bay
iBook	Under Keyboard and Inside Battery Bay
MacBook	Inside Battery Bay or Bottom*
MacBook Pro	Inside Battery Bay or Bottom*
MacBook Air	Bottom*

* MacBook and MacBook Pro models with batteries that are not designed to be removed by the end user and MacBook Air models have Serial Numbers etched on the bottom. MacBook and MacBook Pro models with removable batteries have the Serial Number inside the battery bay (either on the bottom of the bay or on the side walls).

Not on my MacBook Pro! I only have a model number; not a serial number.

Yes it is, please review Identify your MacBook Pro - Apple Support

On the iMac it's on the foot of the stand.

Also, had you kept the original boxes the serial number information is clearly marked on those as well. Keeping these boxes helps to sell the machines too, they give the impression the owner cares for their equipment.
