    在这个步骤中使用的工具:
    Heavy-Duty Suction Cups (Pair)

    • 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.

    • 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 third picture, we made one out of a bent paperclip.

    • 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. A pencil or pen can be placed under the top edge of the display, parallel to the top edge and extending past the edge of the computer, to keep the first side propped up while lifting the second.

    • 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.

    • Use a pair of tweezers to pull the vertical sync ribbon cable out of its socket on the LED driver board near the top left corner of your iMac.

    • On some iMacs this may not be a ribbon cable but four separate, very fine and very fragile wires. Be very careful, if the tweezers slip off the plug, you will very likely pull a wire out of the assembly.

  6. Installing iMac Intel 27" EMC 2309 and 2374 Dual Drive: 步骤 6 中的图像 1,1
    • Rotate the display out of the outer case enough to disconnect the LED backlight power cable from the LED driver board.

    • Squeeze the two display data cable connector arms together to unlock it from its socket on the logic board.

    • Pull the display data cable connector away from its socket on the logic board.

    • Be very careful when disconnecting this cable as both the cable connector and logic board socket are extremely fragile. When reconnecting the cable later, use as little force as possible.

    • Lift the display for enough clearance to disconnect the LCD thermal sensor cable connector from its socket on the logic board.

    • If your fan is spinning full speed after completion, check this connection or the hard drive's thermal sensor cable. The thermal sensor connector socket is very fragile, so be very careful when you connect back the sensor cable.

  9. Installing iMac Intel 27" EMC 2309 and 2374 Dual Drive: 步骤 9 中的图像 1,1
    • Carefully pull the display toward the top edge of your iMac and lift it out of the outer case.

  10. Installing iMac Intel 27" EMC 2309 and 2374 Dual Drive, Optical Drive: 步骤 10 中的图像 1,1
    • Remove the four T10 Torx screws securing the optical drive to the outer case.

  11. Installing iMac Intel 27" EMC 2309 and 2374 Dual Drive: 步骤 11 中的图像 1,1
    • Pull the optical drive thermal sensor connector straight away from its socket on the logic board.

    • Insert a spudger between the optical drive connector and the optical drive.

    • Twist the spudger to slightly separate the optical drive connector from the optical drive, then use your fingers to pull the connector away from the drive.

  13. Installing iMac Intel 27" EMC 2309 and 2374 Dual Drive: 步骤 13 中的图像 1,1
    • Lift the left edge of the optical drive slightly and pull it away from the right side of the outer case.

    • During reassembly, note that there are two holes in the optical drive face plate into which two stubby plastic posts must engage for proper positioning.

    • Peel back the portion of aluminum tape highlighted in red, leaving the rest attached to the black plastic optical drive bracket.

    • It is not necessary to peel all of the EMI tape off the optical drive bracket.

    • Use the tip of a spudger to press each of the optical drive bracket tabs out of their slots on the bottom of the optical drive.

    • Rotate the optical drive bracket slightly away from the optical drive.

    • Pull the optical drive bracket away from the open end of the optical drive, minding any tabs that may get caught.

    • Use the tip of a spudger to peel back the piece of foam tape covering the optical drive thermal sensor.

    • Use the flat end of a spudger to carefully pry the thermal sensor up off the adhesive securing it to the optical drive.

    • If you have a disc or anything else stuck inside your optical drive, we have a guide to fix it.

  18. Installing iMac Intel 27" EMC 2309 and 2374 Dual Drive, Optical Drive Enclosure Faceplate: 步骤 18 中的图像 1,1
    • Remove the three 3.0 mm Phillips screws from the optical bay enclosure.

    • Starting from the left edge, gently pull open the optical bay enclosure.

    • Continue to pull open the two halves of the enclosure until they separate.

  20. Installing iMac Intel 27" EMC 2309 and 2374 Dual Drive: 步骤 20 中的图像 1,1

    • Lift the black plastic faceplate out of the optical bay enclosure.

    • You will no longer need the faceplate or the two Phillips screws that held it in place. Set those parts aside if you ever wish to put the faceplate back into the enclosure.

    • Reassemble the optical bay enclosure without the faceplate, reusing the original three 3.0 mm Phillips screws to keep it intact.

Not terribly difficult, though I did install an SSD in my son's 20" iMac. Used the OWC data doubler bracket, which, of course, isn't designed for the iMac. I had to bend some metal in order to make it work at a very basic level, but otherwise didn't run into any real roadblocks.

I used OWC Data Doubler. Fit no prob.

Success, and not as difficult as I thought. Getting the glass out (27") was a bit nervous but it's strong and the suction cups work well. The display itself has a heavy frame around it so also is strong. I used a large soft artist's brush to dust the display and inner glass. I carefully used needle nose pliers on the cables and connectors, couldn't get enough grip with tweezers.

I have iMac late 2009 (EMC 2374) and the optical bay fits well into it. I installed Samsung SSD 850 PRO 256 Gb with a documented speed 520/550 (write/read). But unfortunately it seems because of ODD (optical disk drive) link I've got only 250/270. Anyway I'm pretty happy, because I merged SSD with my hybrid HDD 2 Tb (150/150) and now have 2.25 Tb Fusion drive with about x2 speed. My advise - don't buy expensive SSD with high speed if you want to link it through optical bay - the speed will be cut anyway.

The real matter is the interface that is an old 3GB/s instead of a recent 6GB/s that limit the performance of SSD drive
