If this is a 2006 iMac, you do not have the orignal gray colored installation disks?
You didn't make a backup of your entire current OS X system and data before deciding, arbitrarily to completely wipe your hard drive and do a clean install?
If you do not have your orignal, gray system install discs, the only way to get back to OS X 10.7 Lion, is to purchase an retail install disc of OS X 10.6 Snow Leopard.
Unless you already have a retail OS X 10.6 Snow Leopard install disc to use.
After you do the initial OS install, you need to use OS X Software Update feature to update to OS X 10.6.8 Snow Leopard so you have, once again, access to the Mac App Store. The Mac App Store only became available when OS X 10.6.7 became available.
I do not have the original disk because I got the iMac from a friend of mine. And he didnt have the disk either because he got the iMac from someone else. I didn't back up the entire system.. the only items I do have backed up are things like Music, Photos, Documents, ect. I thought about buying Snow Leopard but I didn't want to have to spend the extra money since I just purchased OS X Lion.
You need to install Snow Leopard first before being able to install Lion.
Yes, it is going to cost you $40 to do so.
Here is Lion's system requirements in case you doubt me.
OS X Lion system requirements
To use Lion, make sure your computer has the following:
- An Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
- Mac OS X v10.6.6 or later to install via the Mac App Store (v10.6.8 recommended)
- 7 GB of available disk space
- 2 GB of RAM
I just thought of something... Do you think I could use the Mac Mini's in my Computer Repair/Networking class to get to the OS X Lion installer? I could get on their App store and put in the key I got from Apple then put the installer onto a flash drive. After its on the flash drive I could bring it back home and pop it in my iMac. You think that could work?
I am not sure. I am not sure if the actual installer part of Lion is not tied to your Apple ID on a Mac or not.
There is a procedure for installing the OS installer onto USB Flash drive. It wouldn't hurt to try this approach.
