iMac Intel 27" EMC 2429 Hard Drive Replacement

Introdução

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

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.

    • Stick a heavy-duty suction cup near each of the two top corners of the glass panel.

    • To attach the suction cups, first position the suction cup with the movable handle parallel to the face of the glass panel (as indicated 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 indicated 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 because if one of them fails to stick, you could drop the screen and break it.

    • The original iMac box makes a good place to store the glass panel. Otherwise, a padded horizontal surface, like a towel on a desk, will do nicely.

    • 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.

    • Don't use the suction cups to carry the glass panel—if either one loses its grip, the panel could fall and break.

    • After setting the glass panel down safely, be sure to release the suction cups, as the suction force over time can crack the glass.

    • 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.

    • 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.

    • 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. A pair of angled tweezers can also work well.

    • 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.

    • 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.

    • This step brings 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 backlight driver cable with your hand by pressing the tab down and sliding it towards the bottom of the display.

    • 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.

    • Lay the display face down on a flat, soft surface.

    • If you are replacing the display panel, you will need to transfer additional components from the old panel to the new one. Compare the back of the old display with the replacement display. Note all cables, sensors, and foam cushioning that are missing from the new display.

    • If there is a wire or cable underneath adhesive tape, always pull the tape off first. Do not pull on the cable directly.

    • If the cable is glued to the chassis, use a heated iOpener or a hair dryer to soften the adhesive first. You can then slide an opening pick underneath the cable to loosen it. Never pull on the delicate connectors.

    • Slide an opening pick underneath the foam cushion pieces to separate them from the display, and gently pull them off. You may need some double sided tape to re-attach them to the new display.

    • Follow the next steps if you are replacing your hard drive with an SSD kit.

    • If your SSD enclosure looks like the first image, follow this guide instead.

    • Line up the SSD connectors with the metal enclosure's sockets.

    • Press the drive against the enclosure sockets until the SSD is firmly seated.

    • The SSD connects with the enclosure in only one direction. If the connectors don't line up, rotate the SSD and try again.

    • Peel the white liner off the back of the small temperature sensor board in order to expose the adhesive.

    • Adhere the temperature sensor board to an exposed, metal surface of the SSD, close to the SATA connector.

    • Fold the excess temperature sensor wires so that they are out of the way while you install the enclosure.

    • The images used in this step come from a 2017 iMac. Your cables may look slightly different, but the procedure remains the same.

    • Slide the SSD enclosure into the space previously occupied by the hard drive.

    • Route the SATA cables so that they will not interfere with any other components.

    • Try to keep the cables free from any sharp bends, and route them such that they are not pinched.

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.

You don´t need to short out the wires, just install the free SSD FAN CONTROL app from EXIRION.NET und you´ll be fine :D

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)

I'm looking to replace my 3.5" HDD in my iMac (mid-2011) with a 2.5" SSD. Will I need an adapter for this?

admiralpumpkin - Responder

Absolutly. You can buy a official one on the Apple Store. I reccommend the dual-drive (HDD & SDD) tho.
