Had to return my iMac Retina 27 today

After learning that PT12 will not work with El Cap for maybe 6 months or so, I called Apple Care about getting Yosemite installed on my one week old iMac.
They said it could be done only at the Apple Store since Yosemite needs an installer installed on the iMac first. So they made an appt for me to bring it in, I did, and the Genius said that was not an option.
So I just left the computer there and got a refund.
Will start shopping for a refurb i7 Mac.

Now I realize that Avid posted today that PT12 works now with El Cap, but my experience with 12.3 is no it will not. Because neither of my Avid interfaces show up, only PT Aggregate.
I have updated drivers on my 003+ and my Eleven Rack to no avail.
