Use this guide to replace or upgrade your hard drive for more storage space.

  1. Lay your iMac front side down on a table with the lower edge facing yourself.

    • The glass panel is fixed onto the front bezel with fourteen magnets around its perimeter.

    • Stick two suction cups to opposing corners of the glass panel.

    • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

    • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

  2. Gently pull the glass panel straight up off the iMac.
    • Gently pull the glass panel straight up off the iMac.

    • The glass panel has several positioning pins around its perimeter. To avoid shearing these pins off the glass panel, be sure to only pull straight up during removal.

    • Be meticulous about cleaning the LCD and the inside face of the glass panel before reinstallation, as any fingerprints or dust trapped inside will be annoyingly visible when the display is on.

    • When replacing the glass, be sure there's nothing between the glass and the frame. Stray cables could be damaged or crack the glass.

  3. Remove the following 12 screws securing the front bezel to the rear case:

    • Lift the display panel from its left edge and rotate it toward the right edge of the iMac.

  9. With the display panel still lifted, disconnect the four inverter cables. During reinstallation, place the four inverter cable connectors in voids between components attached to the rear panel so the display panel will sit flush on the edges of the rear case.

    • (combined into one plug in on the 24")

    • Be sure to keep track of the cables, as they do not have proprietary sockets. Mismatched cables can cause screen issues.

  10. To remove the hard drive bracket, squeeze the middle against the side of the hard drive while rotating the top left edge toward yourself. After the left edge has been freed, rotate the bracket toward the right edge of the hard drive. Lift the hard drive bracket straight up off the chassis.

Because there are no instructions for the 24", I used these and they worked fine. I shelled out $10 for the suction cups ifixit provides, but honestly the glass is really thin and lightweight, so cheapo suction cups from Home Depot should work just fine.

I couldnt agree more. The "Glass" is of couse plastic. I bought some whimpy suction cups in multi pack from Target and after i stuckem to the glass, it came off almost to easy. I was expecting a fight, i didnt get one.

I am about as untechnically proficient as you can imagine, yet replacing the hard drive was not as daunting as it first seemed when following these FANTASTIC step by step instructions. I was forced to do this because of a lack of money, but having done it, I'm glad I did. Even if I had the money, it's not worth the $500 it costs to have an Apple dealer or Apple themselves replace the hard drive. Just take your time and don't force anything, and you should be done in no more than an hour. Kudos ifixit!

On my 24" iMac, I only needed to disconnect the first LCD Cable (before removing the LCD's torx screws), then I was able to pivot the LCD up 90 degrees, to get access to the hard disk. It was nice not having to disconnect (and reconnect the 2nd and 3rd cables. Now I have 3TB! (Seagate Barrracuda ST3000DM001). Note: I first tried putting the 3TB disk into an SATA USB enclosure, so I could transfer the data before opening up the iMac, but I found out the some of the older USB enclosures don't work with >2TB disks.

I followed the guide, and it worked fine. The new HD is working without problems. But now my Mac has a buzzing noise on it's top left part. What should I do?
