    • Before beginning, unplug your iMac and lay it on a soft surface as shown.

    • 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. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

    • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

    • 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.

    • Slightly lift the top edge of the display out of the outer case.

    • Do not lift it too much. There are several cables attaching the display to the logic board. Twisting or pulling the display assembly with the cables attached will damage your iMac.

    • Rotate the display out of the outer case enough to disconnect the LED backlight power cable from the LED driver board.

    • Disconnect the LED backlight power cable by depressing the locking mechanism while pulling the connector away from its socket (toward the bottom edge of the iMac).

    • Grab the plastic pull tab secured to the display data cable lock and rotate it towards upwards.

    • Pull the display data cable straight out of its socket on the logic board.

    • Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.

    • 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.

  16. iMac Intel 21.5" EMC 2428 Hard Drive Replacement, Replace the hard drive with an SSD: шаг 16, изображение 1 из 3 iMac Intel 21.5" EMC 2428 Hard Drive Replacement, Replace the hard drive with an SSD: шаг 16, изображение 2 из 3 iMac Intel 21.5" EMC 2428 Hard Drive Replacement, Replace the hard drive with an SSD: шаг 16, изображение 3 из 3
    • 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.

    • Use a Phillips screwdriver to install the four silver screws (two on each side) along the edges of the SSD to secure it to the enclosure.

  18. iMac Intel 21.5" EMC 2428 Hard Drive Replacement: шаг 18, изображение 1 из 2 iMac Intel 21.5" EMC 2428 Hard Drive Replacement: шаг 18, изображение 2 из 2
    • Plug the included sensor-enabled SATA power cable into the enclosure's port.

    • The cable is keyed to connect in only one orientation. If you can't connect the cable, rotate it 180° 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.

    • Use a T8 driver to install the mounting pins from the old hard drive onto the sides of the enclosure.

  21. iMac Intel 21.5" EMC 2428 Hard Drive Replacement: шаг 21, изображение 1 из 2 iMac Intel 21.5" EMC 2428 Hard Drive Replacement: шаг 21, изображение 2 из 2
    • Attach any mounting brackets removed from the old hard drive onto the enclosure.

    • Connect the iMac's SATA power cable to the other end of the new sensor-enabled SATA cable.

  23. iMac Intel 21.5" EMC 2428 Hard Drive Replacement: шаг 23, изображение 1 из 2 iMac Intel 21.5" EMC 2428 Hard Drive Replacement: шаг 23, изображение 2 из 2
    • Connect the iMac's SATA data cable to 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.

Hi guys, the tools arrived today and I did already chage the default harddisk against the WD Velociraptor 500GB. For now everything is working fine. The iMac is in the middle of restoring the time maschine backup. Everything worked out as described. Excellent! I was just a little surprised by the magnetic forces which one needs to overcome gently...

Is there a temp sensor that monitors the HD? I did the upgrade but now my fan is always on. I must've done something wrong.

Did you use the same brand hard drive? Did check the instructions about cable orientation on the hard drive? Did you double check the LCD thermal sensor cable?

Take a glance at this page for full explanations:

I had the same issue here (after replacing the original HDD by a 1TB WB Caviar Blue) and it has been fixed by this utility.

HTH,

In response to the software, that does work, however, it can be taken care of hardware wise if our recommendations are followed.
