If you can get used to using it (which really just requires some practice), the screen magnifier on Mac is fantastic and most importantly it’s extremely low latency (by this I mean, it reacts pretty much instantly when you want to zoom in or out).

Once you get used to flicking in and out of zoom instead of leaning into the monitor it’s great.

As an aside, Windows and Linux share this property too nowadays. Using the screen magnifiers is equally pleasant on any of these OSes. I game on Linux these days and the magnifier there even works within games.
