Introduction

The display must be removed to gain access to most of the internal components on your iMac.

Image 1/2: Remove the access door from the iMac. Image 2/2: '''Before beginning the repair, unplug the computer and press and hold the power switch for 20-30 seconds, to discharge internal capacitors.'''
  • Loosen the two captive Phillips screws securing the access door to the iMac.

  • Remove the access door from the iMac.

  • Before beginning the repair, unplug the computer and press and hold the power switch for 20-30 seconds, to discharge internal capacitors.

That is a really, really unnecessarily complex way of fitting a new hard drive. Thanks, but no thanks...

annax, if you can suggest a simpler way we're all ears!

I found this guide to be very useful. The installation was super easy, especially since I've never opened my iMac before. I was able to skip steps 6, 7, 9, 10 and 14. Wish I had one of those long skinny magnetic torx screwdriver's though. I had to use duct tape to hold the screws on the end of the bit for step 12.

I used this opportunity to vacuum out the dust with mini attachments. Much needed after 3 years ;0)

Awesome site!!! Thanks for sharing your knowledge and saving me time and $$$!

  • Flip your iMac over and lay it stand-side down on a flat surface.

  • To lift the front bezel off the iMac, simultaneously:

    • Use your thumbs to press in the RAM arms and hold the iMac down.

    • Use your index fingers to pull the small bridge of material on the front bezel toward yourself.

    • Pull the Front bezel up with your index fingers.

  • Once the small bridge of material has cleared the RAM arms, lift the front bezel by its lower edge just enough to clear the bottom edge of the rear case.

  • Re-orient your iMac so it sits upright on the stand.

  • Insert a plastic card up into the corner of the air vent slot near the top of the rear case.

  • Push the card toward the top of the iMac to release the front bezel latch.

  • Pull the front bezel away from the rear case.

  • Repeat this process for the other side of the front bezel.

  • It may be necessary to apply several layers of duct tape to the top of the access card to aid in releasing the latches.

  • If the bezel refuses to release, try pressing the lower edge back onto the rear case and repeat this opening process.

Apple uses a powerful magnet to release these latches, but the official tool is not available. If you have access to a few failed hard drives, you can take out the magnets from those, and stack them up to have a magnet strong enough to easily open these latches.

Simply place the magnet on an upper corner of the machine, and when you hear a click, gently pull the corner of the front case forward. Repeat the process for the other upper corner. Use care not to pull on the iSight cables.

Note: Use care when handling the hard drive magnets, they are powerful, and you don't want them to snap together on your fingers. OUCH!

You can use a credit card. Mine survived, though it did get a little bent.

David Bendory - Reply

I used two credit cards for extra thickness and the latches released very easily.

James French - Reply

The magnetic latches are about 2-3 cm from the left and right edges right at the top edge of the case. I just ran a rare-earth magnet over the from of the bezel in this area. You can hear it click when it disengages. RadioShack has these kind of magnets for $3, the call them "super magnets".

James - Reply

This was a nuisance. Had to really move the card around to get it to finally release.

Tim Dougherty - Reply

Be very careful not to damage the metal clips with a credit card. My iMac was very stubborn and I ended up bending the clips in a way they cannot be bent back. The clips do still work and the front bezel does still go back on, however it no longer sits flush with the back of the iMac.

  • Lay your iMac stand-side down on a table.

  • Lift the front bezel from its lower edge and rotate it away from the rest of your iMac, minding the RAM arms that may get caught.

  • Lay the front bezel above the rest of the iMac.

I found that it is much easier if you remove the top of the case first, then lay computer back on the stand & remove the bottom as directed.

  • If necessary, remove the piece of kapton tape(it is ok to toss this) wrapped around the microphone and camera cables.

I was able to skip Steps 6 & 7 entirely. The microphone and camera cables had enough slack to flip the front cover off and lie it flat above the rest of the computer.

Carly Hobeef - Reply

Step 4 is completely unnessecary. Just lift the bezel up and wiggle it until the metal clips let go. Then lift the bezel straight up.

  • Disconnect both the camera and microphone cables.

Make sure the white wire is on the same side of both parts of the connector before reconnecting.

It is possible to reconnect the microphone cable in the wrong/reversed orientation with the connector. The microphone will still work but will be muted and result in a "tinny" sound on the receiver's end.

Can anyone ID these connectors (at least the camera connector) so that I may make an extension (to move the camera out and re-house it myself). I probably have the gear to do the mic already.

Is the camera connector some standard I can order M & F versions online to terminate to an extension cable?

  • Pull the inverter cable connector straight up off its socket on the logic board.

The inverter connector had a different location for me. It was situated next to the top left corner of the right speaker, just under the display. I didn't figure this out until I actually lifted the display off the computer.

Cloudsurfer - Reply

My 17" iMac also has the inverter cable. It located in the upper right just below the display.

Clinton - Reply

I couldnt get this cable off, so I skipped this step. If you have this problem, just proceed; when you get to step 13, lift the display carefully as this cable will still be attached. You'll now easily be able to grip the connector and remove it.

Only peel back the black EMI tape that overlaps the edge of the display, not the silver tape on the display itself.

Odesseus - Reply

The above note sounds as if one should peel the aluminum-foil colored tape back from the frame. Do NOT do this; instead, peel the BLACK-colored aluminum tape back from the display frame to reveal the crevice between the display and the case and the mounting screws you are about to remove.

Byron Bray - Reply

I didn't actually need to peel anything at all. The screws would have been visible had I looked more carefully.

  • Allow the EMI shield to hang down from the display.

  • Remove the four 8 mm with 2 mm thick head coarse-thread T10 Torx screws securing the display to the rear case.

  • These screws are recessed, so a thin screwdriver such as this is essential for removal. Bit drivers tend to be too short for this application.

  • It is strongly recommended to use a magnetized screwdriver so the screws won't fall into the iMac.

To put the T10 screws back, you'll need a magnetic head T10 screwdriver or a long, tweezer-like device found in a good set of computer tools. The screws are WAY down there and it is difficult if not impossible without the right tools.

Monkee - Reply

If your thin torx driver is not magnetized, you can hold another, magnetized, driver against it as a temporary solution.

Si Brindley - Reply

If you really want to tackle it without proper tools: with a non-magnetised thin torx loosen the screw till its ready to come out, then wrap a little bit of duct tape (sticky side out) around the head of a spare thin screwdriver, gently push the duct taped screwdriver on top of the loosened screw. The magic tape will lift the screws out.

When re-assembling, it's also a good way to fish out the screws that missed the holes completely when your expert fingers skills are classed as clumsy.

Mark - Reply

You must have a magnetized Torx 10, 2 to 3 inches in length to safely get these screws out. Fortunately if you have the T10 you can magnetize it with your iMac.

Inside the front bezel are two magnets that hold your apple remote to the case, simply tap the T10 to the larger magnet 3 or 4 times and test it's strength in holding a weighty screw. You are good to go. I did this and the scary lose a screw into the iMac was diminished with a firm hold in both removal and install.

If you don't have a magnetic screwdriver or they are aluminum screws, you can use this old mechanics tip: Use a small piece of paper or celophane tape on the head of the screw, then press the screwdriver into it, this creates a nice snug hold so you can reinstall the screws.

I was able to slightly bend the plastic case to get my driver to seat. This was the most challenging part of the teardown and reassembly because I did not have the proper tool.

Image 1/1: Be mindful of any cables that may get caught during removal.
  • Lift the display from its lower edge and pull it toward yourself to peel off the EMI shield attached to its top edge.

  • Be mindful of any cables that may get caught during removal.

Steps 14 & 15; If you remove the top screw, and just loosen the bottom screw you can rotate the optical drive clip out of the way, tighten it, then screw the top screw back in to hold the logic board down for later trying to remove the connector. You also save three more parts kicking around on the desktop.

Please be careful at step 5. This is because the wiring attached to the microphone is very delicate and might snap when you are wiggling the bezel free from the rest of the computer. I did this and spent a lot of time soldering back the thin microphone wires. Pull the bezel away carefully, taking care not to snap any of the wires.

This is really a good tutorial! just put in a new display, and it works perfectly.

So proud and happy now :-)

Thanks !!!
