Memory Question

I have only Firefox open and my available memory is 1.48G of 4G max. What is using so much of my memory?

iMac, OS X Yosemite (10.10.5), 3.06 GHz Intel

Open Activity Monitor in your Utilities folder to see what uses memory on the computer. Most of it is taken by Yosemite in order to have better memory management. Are you running out of memory? Is the computer slowing down and the drive is constantly grinding away? If not, then don't worry. Otherwise, put in more memory.

When you have Activity Monitor open click on the Memory tab at the top. Then note the status display at the bottom. Looks somewhat like this:

Make a screen snapshot of yours and post it here.


To post screen shot do this:


  1. Press COMMAND-SHIFT-4 which will change the cursor to crosshairs.
  2. Hold down the mouse button and use the crosshairs to select the part of the screen you wish to capture.
  3. Release the button and the image will be saved to your Desktop.
  4. Click on the Camera icon in the toolbar of the forum message editor.
  5. Drag the image onto the Choose File button and click on the Insert button.

At Crucial I tried to download the system scanner but wasn't able to open. Should I just look for the memory card that I need myself i.e. match the two I have installed already?


Post what year iMac you have. You can easily find out by clicking About this Mac which is located by clicking the Apple symbol in the upper left of your display. Find the OS X version and build number on your Mac - Apple Support


Once we know exactly what iMac you have then we can tell you the RAM specifications to look for.

One MAJOR problem you have is you installed CleanMyMac on your system. This is considered malware by many experienced users. My recommendation before you do any upgrades or changes is to fully uninstall the app. This may be challenging but it needs to be done first. OS X does not need any cleaning, antivirus or third party utilities to maintain itself. If OS X is left alone and just kept up-to-date it tends to function well for years.
