Replace the hard drive in an iMac Intel 27" EMC 2429.

This guide will help you replace/upgrade the hard drive.

Edit Step 1 Glass Panel  ¶ 

  • Stick a suction cup near each of the two top 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 (as highlighted in the second picture).

  • While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle (as highlighted by the third picture).

  • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a damp soft, lint-free cloth. (Dampen with distilled water, and if needed, an equal ratio of distilled water and white vinegar for best results.)

  • Do not use the suction cups to carry the display glass.

  • The original iMac box makes a good place to store the glass panel.

Edit Step 2  ¶ 

  • Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

  • Pull the glass panel away from the lower edge of the iMac and carefully set it aside.

  • During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

Edit Step 3 Display  ¶ 

  • Remove the eight T10 Torx screws securing the LCD to the outer case.

  • Be careful not to touch the display as the oil from your fingers may leave a residue that can be difficult to remove.

  • If necessary, peel the EMI gaskets located near the top center edge of the display assembly.

Edit Step 4  ¶ 

  • Carefully lay the iMac stand-side down on a flat surface.

  • Due to tight tolerances, you will have to use a thin hooked tool to lift the display out of the outer case. As seen in the first picture, we made one out of a bent paperclip.

    • Alternatively, our Dual Hard Drive Kit includes a pair of tweezers with an angled tip that are great for this task.

  • Use a thin hooked tool to lift one side of the top edge of the display by its steel outer frame.

  • After lifting the top edge of the display on one side, hold it out of the outer case while you use a hooked tool to lift the other side.

  • Raise and hold the display high enough to access the cables.

  • Do not lift the top edge of the display out of the outer case too far, as several short ribbon cables still connect the two components.

Edit Step 5  ¶ 

  • Disconnect the vertical sync cable in the upper left corner of the screen. Use the tip of a spudger to push on the connector's side tabs and gently walk it out of its socket.

Edit Step 6  ¶ 

  • This step bring your hands close to the exposed rear of the power supply. To avoid a high voltage shock from the many large capacitors attached to the board, do not touch the rear of the power supply.

  • Disconnect the LED back light driver cable with your hand by pressing the tab down and sliding it towards the bottom of the display.

Edit Step 7  ¶ 

  • Pull the black tab straight up to disconnect the latch on the display data cable ZIF connector.

  • Do not pull up too hard or you will damage the connector and socket.

  • Continue to pull the black tab up toward the top of the device, to detach the display data cable.

Edit Step 8  ¶ 

  • Use the tip of a spudger to disconnect the display power cable next to the display data cable.

Edit Step 9  ¶ 

  • Carefully pull the display toward the top edge of your iMac and lift it out of the iMac case.

Edit Step 10 Hard Drive  ¶ 

  • Disconnect the SATA power and data cables from the hard drive by pulling them straight away from the hard drive.

Image #1

Edit Step 11  ¶ 

  • Remove the two T10 Torx screws securing the hard drive to the iMac frame.

  • Slightly rotate the top edge of the hard drive away from the outer case.

  • Lift the hard drive off its two lower positioning pins and remove it from the outer case.

Edit Step 12  ¶ 

  • Remove the two T8 Torx screws securing the upper bracket to the hard drive.

  • Remove the upper bracket from the hard drive.

  • Remove the two T8 Torx pins from the other side of the hard drive.

Edit Step 13  ¶ 

  • Carefully peel off the piece of EMI foam attached to the front of the hard drive.

  • Don't forget to transfer this to your new hard drive.

To reassemble your device, follow these instructions in reverse order.

Note that if you are replacing the hard drive with a non-Apple hard drive, then you will have problems with the fan running full speed constantly (see http://blog.macsales.com/10206-further-e...). Basically, you'll need to either install a $30 piece of software to control the fans or short out some wires.

remember after the glass, to get the aluminum front off, remove the bay for the memory upgrade on the bottom first before you remove the torx screws ans lift to access the bottom case (Between step 2 and 3)

You can easily lift the glass panel off the magnets with only your fingernails (or something thin like a credit card or a guitar pick). No need to buy suction cups you will only use once.

Yes, you don't need the specific suction cups to remove the display cover - it's held on by magnets, and if you start at the center by the iSight you can work out to the edges and remove it. I had an iPhone screen suction cup around and it helped with balancing the screen when you pull it out fully, but by no ways is it required.

Great guide and pretty straight forward the only thing that took me ages and I didn't manage to undo were the power btn cable (step 28) and the thermal sensor (step 25) Seemed like they were glued on! Very difficult to remove and obviously conscious so I didn't break anything!

Thanks!!! Worked excellently.

I used a plunger (clean first ;-) to get the screen off, and http://exirion.net/ssdfanctrl/ for fan control.

Then, i did not take out the whole display and left it in the hinges on the bottom side and held it up with two small cardboard boxes. Easy enough to disconnect the hdd then.

I replaced with an ssd, put that into a ssd enclosure. Had to drill an extra hole in it to fasten the pins that hold it in place.

Used Carbon Copy Cloner to make an image from the old hdd, with the sad connected via usb. Checked it of it booted via System Preferences > Startup Disk. It worked so the took the imac apart and replaced the disk. Booted, everything was working as always, only faster!

I'm replacing my optical drive too. what exactly needs to be plugged into the SSD? I don't have the kit - as I am not sure one is required if I buy something like this: http://www.amazon.com/gp/product/B0056OB...

Can you please advise? Can I do it with this piece, or do I need to get the entire bracket kit?

Allen Borza,

you should do this mac up, because, for me, one of the suction cup failed, and the glass fall into the lcd screen. Now there is a big hole in it...

Do step 7 first. The cable is much shorter and more fragile, you'll have more space to remove the other cables if that one is removed first. On my mac, the cable in step 7 was glued down and had to be freed up before I could pull the connecter out of its socket.
