When using a Mac and your cursor become an infinitely spinning pinwheel. Often occurring when a programme crashes or when too many applications are opened/being opened at once.
While opening my Adobe software and watching videos online at the same time I was hypnotized by Mac's colourful pinwheel.

I was pinwheeling when I overloaded my Mac with processes.
