Registering Serial for 2nd hand Macbook Air

You really only need to register it for warranty purposes (which, in this case, would no longer be in force). I've found that when I sell Macs and call Apple to inform them, Apple never changes the records (even if they've covered by Applecare). I still have some Macs showing I haven't owned for several years. So, even if your dad called up, it may not result in them changing the record to your AppleID.

So, if you want to pursue it, I'd suggest having your dad calling them up. If you decide not to, simply don't register it.

Have him sign in using his Apple ID and un-register it.

You may then register it as your own.

Thanks! Didn't realize that now works - I tried that once some time ago and still had to call Apple (the buyer needed to use Applecare and for some reason they would not believe that he owned the machine LOL).

It might still be necessary to have some semblance of proof of purchase.

I have an iPod (personalized and purchased from the Apple Store) that I tried to register but it woudn't let me, saying "this serial number is registered to another Apple ID." The nearest I can figure is that someone must have mistyped the serial number of another iPod when registering it.

I never resolved that problem, but it never needed service so it's a moot issue. Still, it would be nice to have had it appear in My Support Profile.

I agree, but apparently having a device ID attached to your ID is as permanent as your ASC ID.... 😝

On Apple support site where you register a product there is also a check box to unregister a product. I have the same problem. I purchased a used iMac and do not know original owner so i cannot contact them to unregister the product. like you i would like to see my Mac listed under "my products" weather its covered under warrenty or not.
