Hi, I have a 2010 iMac. It was running too slow, so I got a new SSD and I had 2 16GB RAM Kit from Crucial from last year, so I used that. This is the one, I had. (see attached) Installed the 240GB Crucial SSD. And Installed 8 ,8, 8, 8 to all 4 slots of the RAM. And I had no yosemite file, so I asked the apple engineer to copy the yosemite from his drive to this new SSD iMac and he did it. Then I was able to switch on the iMac. But when I switch on the system, it shows 64GB. Instead of 8,8,8,8 it shows 8,8,24,24 . (see attached) How is that happening ?
