How do I reinstall Lion to sell my Mac?
I have an iMac Mid-2011 model that I bought from the Apple store. The machine came without installation disks, so I assume it had Lion installed when I bought it. I have since purchased and installed Mountain Lion.
I am now selling the iMac, so I have booted to the recovery partition and run Disk Utility to erase the main hard disk.
Now I want to reinstate Lion so that the buyer will receive the computer as if it had come new from the Apple Store.
I tried to reinstall Lion using the Mac OS Utility and it announced that it would install Mountain Lion, not Lion. It then asked me for my Apple ID and password.
What I would like to know is:
1. Can I just put the machine back to its origianl Lion configuration, as if it had just come from the Apple store
2. If I enter my Apple ID and password, when the buyer gets the machine will he be able to continue to use Lion and will my Apple ID and password be at risk?
