Replacing the hard drive requires separating the display and removing the left speaker.

This guide also includes steps to upgrade your iMac's hard drive with a SSD. It describes how to install the SSD's temperature sensor so that the Mac's fans will operate at the correct speed.

Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply.

  1. Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear case. The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert it no more than 3/8" (9.5 mm) into the display. You risk severing antenna cables and causing serious damage if you insert the tool too far. The hub on the iMac Opening Tool will keep you from pushing the wheel in too far.

  2. Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center. Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle. Run the tool up along the left side of the display.

  9. While the opening tool did the lion's share of the work, the display will still be slightly adhered to the case. A plastic card will be necessary to free up the last of this adhesive. Set the iMac face-up on a table. Starting from the top right corner of the iMac, insert a plastic card between the display and frame.

  22. Be very careful handling the display—it's big, heavy, and made of glass. The display has fragile edges. Avoid lifting the display by the corners. Lift the display up from the frame and remove it from the iMac. Lay the display face down on a flat, soft surface. It may be necessary to slowly lift from one side, to peel against the remaining adhesive.
