Transferring files from old 2008 iMac to new 2015 iMac using Migration assistant and ethernet cable - work fine, albeit 3 hours, until says " About 12 minutes remaining" on the new iMac and About 16 minutes remaining on old iMac, seems to have frozen for last 2.5 hours, ideas?

    You haven't mentioned or tagged the source (2008 iMac) and target (2015 iMac) OS X versions. You might see if this update to Migration Assistant is appropriate for your situation. If you can do it, a Time Machine backup from an external HD can be used in Migration Assistant, too.

Failed hard drive? Select your Apple Menu, hold down the alt/option key, and choose "System Information". Navigate to "Storage". Check the field reading "S.M.A.R.T. Status". It should read "Verified" if OS X thinks everything is OK.
