Hello Apple Support Communities,


I have a 21.5 inch, Late 2009 Intel iMac. Currently it is running OSX Lion. It is also running Bootcamp with Windows 7 Professional Installed. Recently the Hard drive crashed on me and I ordered a new generic Hitachi from an Apple Reseller. I took all the precautions and asked all the questions, but when I finished the hard drive replacement, the fans within the iMac started running on High. The other people in my office Hate this. I did some research and found that there is a firmware update for the SMC that I should be installing. I looked on the webpage where apple directs you to find out if you need this update, but I can't find my exact specs on the page (here is the page for reference: http://support.apple.com/kb/HT1237) I can only find an update for the 27 inch model. I tried running that one and the system tells me "This software is not supported on your system."


Here are the specs that the page requested me to find:

  • Model Identifier:          iMac10,1
  • Boot ROM Version:          IM101.00CC.B00
  • SMC Version (system):          1.52f9



Someone please help, this has been bugging me for a while.

iMac, Mac OS X (10.7)
