    Rating: 5/5 This works great January 8, 2016 My original 1TB 11,3 mid-2010 iMac wouldn't boot anymore. Tried everything. Had earlier upgraded my router to a 2TB AirPort Time Capsule and had an unused 3TB external in an OWC enclosure I was using for backup before the Time Capsule. Hooked the old 3TB external up to my MBP, erased it and installed El Capitan on it and confirmed it would boot. Using this kit, I then swapped the original 1TB in the iMac with the 3TB. iMac booted fine with the 3TB, no fan problems, and happily all data was still on old 1TB. Just copied it all over. The kit worked great. Watched the OWC install video several times first. Also checked several other online install videos, but OWC's was the best. Unplugging and replugging the 4 display connectors was a little dicey, as was removing and installing the 8 screws that held the LCD panel. Dropped one screw but it stopped behind a magnet. Used tweezers in OWC kit to retrieve it. Best part of the kit is how it takes care of the heat sensor problem by sticking a new one to the hard drive case and rewires things to make it all fit. You end up with the unused old Apple jumper wire which ran from the proprietary hard drive socket to the logic board. It is replaced by the wire from the OWC adapter. Took about 40 minutes or so to complete. Highly recommended.

    Rating: 5/5 Problem Solver November 20, 2015 I wish this had been available earlier when I first upgraded my internal drive. Its a fairly price item for getting a replacement drive to be compatible with the iMac's fan control circuitry. Still "Top Marks" to OWC for getting it done. Think about it, who else does this for us?
