lost registration details

[levyrin]

I formatted my computer os Mountain Lion and lost all my entered information, password, computer name etc.
How can I find them?

Could you explain in a little more detail about what you did, how you did it and which Mac you have please?

I transferred my old imac (2009) to my son after formatting it and running os Mountain Lion on it.
I registered it in his name and gave it a name and a password. Unfortunately I misplaced these details and I think he needs them to operate the computer properly.
I now have a new imac, also with os Mountain Lion.
Thanks for helping.

If there's nothing on it I'd just put a clean install of Mountain Lion on. It only takes about 30 minutes.

Sorry, but how do i do that? I don't have a disk of Mountain Lion, can I just reinstall from within the program?

 

[mrplow]

You said you formatted the disk and reinstalled before?

This is why I asked what exactly you did. I'm guessing you didn't format the disk.

Never mind. Going forward. You can create a mountain lion install disc on your new iMac.

You can use Lion DiskMaker to automate the process

Thank you. Won't I need a password throughout this process?

 

[levyrin]

Did you mean for me to make the disk on the new Imac and give it to him?
Won't there be a problem with that?

 

[mrplow]

You may need your Apple ID and password (that you bought Mountain Lion with) to re-download the Mountain Lion installer on your current mac to make the disc

No problem at all.

 

[levyrin]

Thank you very much for your help.
The only problem remaining is that the new Imac does not have a disk player within.
Can I use the Ipad2 in any way? Copy the dmg.file somehow?

 

[mrplow]

It doesn't have to be a disc it can be a USB thumb drive.

 

[levyrin]

Yes, of course
Thanks again
