Last week, my iMac would not turn on. After doing some research I found out it was due to the power supply going bad. I ordered replacement parts and figured, why I'm in there, why not put in a bigger hard drive. I have successfully got my iMac working again with a complete reinstall but now I need to transfer my old HD files to the new one. The old internal mac HD is in an enclosure and that is working fine. What is the best way to do this? I need all user settings and everything. Thanks in advance.
