    My IMac boots normally until like 40% then goes to a black screen with a buffering img. Help?

    What do you mean by "40%"? Does it ever boot to the login screen? I would suggest creating a second partition and doing a clean install on the second partition. You might need to boot to the recovery partition using Cmd-R. If you find it booting fine with the clean install then I suggest a clean install on the primary partition. If it does the same thing again, then I suggest a call to AppleCare. You do get free AppleCare phone support for Yosemite. Could be a hard drive issue.
