    Hello! Today I finally got my first iMac. And I just have one question about activity monitor :).

    When I open Activity Monitor and go Window > CPU Usage I get this little window.

    It looks like it is showing me how much of each core is being used but it is a quad core and there is 8 little rectangles. Can someone please explain it to me :)

    I have the 4 Ghz Quad Core i7 late 2015.

    All help is appreciated.

    Hyperthreading. The 4 physical cores are treated as 8.
