Installing memory

The internal components of your iMac can be warm. If you've been using your iMac, wait ten minutes after shutting it down to let the internal components cool.

After you shut down your iMac and give it time to cool, follow these steps:

1. Disconnect the power cord and all other cables from your computer.
2. Place a soft, clean towel or cloth on the desk or other flat surface to prevent scratching the display.
3. Hold the sides of the computer and slowly lay the computer face-down on the towel or cloth.
4. Open the memory compartment door by pressing the small grey button located just above the AC power port:
5. The memory compartment door will open as the button is pushed in. Remove the compartment door and set it aside:
6. A diagram on the underside of the compartment door shows the memory cage levers and the orientation of the DIMM. Locate the two levers on the right and left sides of the memory cage. Push the two levers outward to release the memory cage:
7. After the memory cage is released, pull the memory cage levers toward you, allowing access to each DIMM slot.
8. Remove a DIMM by pulling the module straight up and out. Note the location of the notch on the bottom of the DIMM. When reinstalling DIMMs, the notch must be oriented correctly or the DIMM won't fully insert:
9. Replace or install a DIMM by setting it down into the slot and pressing firmly until you feel the DIMM click into the slot. When you insert a DIMM, make sure to align the notch on the DIMM to the DIMM slot. Find your model below for specific installation instructions and notch locations:
   • iMac (Retina 5K, 27-inch, 2020) DIMMs have a notch on the bottom, slightly left of the middle. If your DIMMs are mixed in capacity, minimize the capacity difference between Channel A (slots 1 and 2) and Channel B (slots 3 and 4) when possible.
     
   • iMac (Retina 5K, 27-inch, 2019) DIMMs have a notch on the bottom, slightly left of the middle:
   • iMac (27-inch, Late 2012) and iMac (Retina 5K, 27-inch, 2017) DIMMs have a notch on the bottom left:
     
   • iMac (27-inch, Late 2013) and iMac (Retina 5K, 27-inch, Late 2014, Mid 2015, and Late 2015) DIMMs have a notch on the bottom right:
     
10. After you install all of your DIMMs, push both memory cage levers back into the housing until they lock into place:
    
11. Replace the memory compartment door. You don't need to press the compartment door release button when replacing the compartment door.
12. Place the computer in its upright position. Reconnect the power cord and all other cables to the computer, then start up the computer.
    

Your iMac performs a memory initialization procedure when you first turn it on after upgrading memory or rearranging DIMMs. This process can take 30 seconds or more, and the display of your iMac remains dark until it's finished. Make sure to let the memory initialization complete.

If your iMac makes a tone after you install memory

iMac models introduced before 2017 might make a warning sound when you start up after installing or replacing memory:

• One tone, repeating every five seconds signals that no RAM is installed.
• Three successive tones, then a five-second pause (repeating) signals that RAM doesn't pass a data integrity check.

If you hear these tones, confirm that the memory you installed is compatible with your iMac and that it's installed correctly by reseating the memory. If your Mac continues to make the tone, contact Apple Support.

Confirm that your iMac recognizes its new memory

After you install memory, you should confirm that your iMac recognizes the new RAM by choosing Apple () menu > About This Mac.

The window that appears lists the total memory, including the amount of memory that originally came with the computer plus the newly added memory. If all the memory in the iMac has been replaced, it lists the new total of all installed RAM.

For detailed information about the memory installed in your iMac, click System Report. Then choose Memory under the Hardware section in the left side of System Information.

If your computer doesn't recognize the memory or doesn't start up correctly, confirm that the RAM you installed is compatible with your iMac and that it's installed correctly by reseating the memory. If you continue to have issues with the memory in your iMac, contact Apple Support.

Have you heard about Spotify airplay ?

You’ve probably heard about Spotify, the music streaming service that gives you access to millions of songs at the click of a button.

There are multiple levels of membership, so you can choose the one that works for you, and in no time, you’ll be listening to your favourite songs and you can do it on a variety of platforms and devices.

You can load Spotify onto your iPhone and stream music that way, but it does take up space, it also requires a lot of your phone’s memory. If you are at home, with access to your home computer and your wifi network, you can use Airplay to stream music directly from your Mac to your iPhone. Airplay can be run in the background and is not as intensive as Spotify, so you can run it while still using your phone for other things.

Using Airplay to Play Spotify

• Step 1: Make sure that your Mac and your iPhone are connected to the same WiFi service.
• Step 2: Go your computer and on the keyboard, hold down Alt and press the Volume menubar icon.
• Step 3: Open your Menu bar and click on the speaker icon and then select your iPhone under Airplay Devices.
• Step 4: Your iPhone should now be playing music automatically, from the Spotify playlist on your Mac.

Streaming music from your computer to your iPhone is convenient when you wish to use your phone for other things and don’t want to be stuck in the Spotify app. The Spotify app is great for travel and for times when you just want to be listening to music, but there are times when you want to be able to listen to music while still doing other things with your phone.

Besides, Airplay is not limited to your iPhone. You may want to stream from Spotify to another Apple device, most notably Apple TV. Spotify is not yet available on your Apple TV, but Apple TV is Airplay accessible, so you can access Spotify on your Apple TV that way. To stream from your Mac to your Apple TV, you follow the steps above and select Apple TV instead iPhone.This is great if you are having a party and want to stream music, but your computer is upstairs and your Apple TV is in your living room.

But sometimes you don’t mind using your computer to stream your music while you are off doing other things, you just wish you didn’t have to constantly get up and go back to your computer to manager your songs and you don’t have to. You can use Spotify Connect to manage your various Spotify devices remotely. This allows you to use your iPhone to manage the music that is currently being played by Spotify on your Mac.

Spotify Usage Statistics

Using Spotify Connect

• Step 1: Make sure that your Mac and your iPhone are connected to the same wireless network.

• Step 3: Open up Spotify on your Mac and start streaming.
• Step 4: Open Spotify on your iPhone and click the Connect icon in the Menu. If the icon is circled, it means that there are multiple devices that are able to be accessed via connect.
• Step 5: Start using your iPhone to skip songs or change playlists on your Mac.

Just like there are times when you want to be able to stream music from your computer to your iPhone, there will be times when being able to remote connect from your iPhone to your computer will come in handy.

However, you can keep your iPhone next to you and it’s much easier to grab your phone and manage your music, then to keep going back and forth from your computer.

You might not ask why not just stream from your iPhone? Because you probably have a better sound system on your computer than you do on your iPhone. So if you want to be able to listen to music at the best quality, without having to sit at your computer, using connect on your iPhone is a great option.
