My father's 27inch early 2011 imac needed a little upgrade. I went and put in a Crucial 500gb SSD disk into it into where its old hard drive used to be.
When we boot, i am getting the question mark with a folder. I tried holding the Alt option and in doing so only the internet recovery comes up. I tried command R and same thing.
Anyway, so I chose the internet recovery. It took 20mins. Then it came to the menu where I could choose disk utility. I went in and could see the SSD. I formatted my SSD to Mac format (journaled). I restarted it and still same. Then i tried doing something similar to choose it as the startup disk but I can't. I tried attaching an external disk with Mac Sierra installation on it. It isn't giving me the option of seeing this disk either at startup.
What gives? Is it the Mac itself? Should I take the SSD and install it onto a MacBook Pro and try putting the OS on it that way?
Thanks for helping
