The one thing about the Mac product that puzzles me is how to right click on anything? My old Dell desktop, now frozen at XP, is simpler to navigate at that level.
It supports a two button mouse if you want or need to work in that manner but comes with a one button mouse, so the answer is get a mouse that you can right click on.
Old Mac mice had only one button. Jobs thought it was simpler that way. He wasn't right about everything.
With a one-button mouse, you Ctrl-Click to bring up a context menu.
Modern Mac mice have touch sensitive surfaces that allow you to left- and right-click and swipe-scroll within and between windows (e.g., swipe to the right to bring back the previous web page).
But touch pads are replacing mice. E.g., on my touch pad, a one-finger tap left-clicks, a two-finger tap right-clicks, two-finger drag scrolls, three-finger drag drags, four-finger swipe left or right switches desktops, four-finger swipe down exposes the desktop, four-finger swipe up opens Mission Control, where you can rearrange desktops.
Oh, and in Chrome and Safari, two-finger double-tap invokes Smart Zoom: the browser determines the width of the column of text in which you tapped and expands the column to fill the full width of the window. Great for when the text is too small to read comfortably. Double-tap again to return to normal. A killer feature, which has weaned me away from Firefox.
