    • 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.

    • The Bluetooth board is located along the left edge of the iMac's case and just below the LED back light driver.

    • Use the flat end of a spudger to gently pry the antenna cable off of its socket.

    • Do not disconnect the antenna by pulling on its cable, as this may damage the antenna or its socket.

    • Remove the T8 Torx screw securing the Bluetooth board to the case.

    • Do not attempt to completely remove the board yet, as it is still attached by a cable.

    • Remove the tape wrapped around the Bluetooth board, being careful not to put to much tension on the still connected cable.

    • Use the flat end of a spudger to pull the Bluetooth data cable out of its connector and remove the Bluetooth board.

Hi Guys

Can i update the the Bluetooth to bluetooth 4.0 on my iMac 27" 2429? want to use new Yosemite Handoff feature

chris - Responder

I updated bluetooth to 4.0 with Low Energy support with an external USB dongle. However, as it is working (with LE support), handoff isn't enabled. I am still looking for a solution. Because a late 2012 27 inch iMac has Bluetooth 4.0 LE and no Wifi ac built in. That is the exact same case as mine (Mid 2011 27 inch iMac) with the dongle of course.

yes, you have to buy this adapter http://www.osxwifi.com/apple-broadcom-bc... and replace the current AirPort and BT card.

@jiri.hracek: Thank you for the suggestion.

Have you bought anything from osxwifi.com? I wanted to buy this adapter from them for my mid-2011 iMac but had a question first. I sent a message to their advertised email address twice ([http://mailto:support@osxwifi.com|support@osxwifi.com)] and also filled out the communication form on their web site (http://www.osxwifi.com/contacts). It has been nearly two weeks but no one has gotten back to me yet. Thank you.
