Well I have just about everything ready now. Why can't anything be easy??
I got the MM home and found out it was a 2011 model but brand new. I could have have a bought a 2012 model for the same money. The 2012 model has USB3 ports instead of USB2 ports, on well I'll just live with it.
I had problems from the very beginning, I was going to use my debit card to pay for it, and it exceeded my daily limit, so I had to call the bank to get my DL increased. Got home and was planning to use a HDTV I already had, but the TV didn't have enough resolution for the MM so it wouldn't sync. Back to town to buy a Monitor.
Sat down to transfer my data from the Backup drive, and that's when I found my original problem. I have a backup drive and an extra drive to store things on. The HD in my iMac was small so I had bought a 1TB drive to use for extra storage, well I didn't have a backup of the extra drive so about 3 weeks ago I bought a 3TB drive to use for a backup, Mac calls the Backup drive the Time Machine, so I used the TM to backup everything on the iMac and had a recent copy of everything. When I went to transfer my data to the MM that's when I found out my 1TB drive had crashed, and that was what keeping my iMac from booting. After I unhooked the 1TB drive the MM booted just fine. I still have a 500GB drive, and between that and the HD in the MM I had enough space to store everything.
It took some time to transfer the data, Apple makes it easy, they have a Migration Utility to do all the work for you. After that since I had an older model I had to DL all the updates, again Apple makes that easy as well. My iMac was 2 versions down on the OS so some of my programs had to updated as well. I have that done.
Now I am downloading the newest OS Mountain Lion for it. And I'll be going to town later to buy a Superdrive for it. Some of the new Macs don't come with a DVD drive so you have to buy an external for it. Later I will be buying a Firewire 800 Drive for it.
This new MM is so much faster than my old iMac, I really like it so far.
