I find much joy in monitoring my Apple computer's fan roll through monitoring CPU use.

However, I don't know how to make multiple "Activity Monitor" windows, each for one of my "Desktop"s.

I normally fought that by staying in "Desktop 1" as much as possible. However there are moments when I really really need several "Desktop"s, while at the same time being monitoring CPU use.

Got ideas?

Start Activity Monitor and an icon will show up in the Dock. Right-click the icon and you'll get a popup with one of the lists of actions is Options. Click on Options and select "All Desktops".

  • Oooooh yesss! ...as I'm in a 13 inches macbook, I think my Dock has to be right sided and always hidden unless hovered. That has been for so long, it just didn't pop off my head.

  • @NimeshNeema works in as late as Mojave 10.14.5. You must be at a later Mojave which removed the feature.

  • @uprego I am on 10.14.5. Do you need to press/hold any key when right clicking on the Dock icon? Any other setting that needs to be enabled for the Assign To sub menu to appear? I am not getting the Assign To submenu.

  • @NimeshNeema I dunno what's the "Assign To" sub you refer to. My Dock is hidden auto appear on hover. If I click an open (maybe is important?) application, I can see almost the same as shown in the pic at apple.stackexchange.com/a/362647/146438. Without having to press or hold any keyboard key. 🙇
