Reading this before I updated to Tahoe beta, I was worried that they made the dots much smaller.If they would just make the three colored dots bigger that would have solved 75% of the problems. And do not anyone tell me to use a keyboard. My hand is ALREADY on the mouse, why should I move it? One needs a damn electron microscope to access those effing dots F U Apple! I'll say it again, NO MAJOR change was/is necessary. It is all make work BS. Reeks of "big brother knows best".
However they are at least the same size, if not larger (they definitely look bolder).
I bought my first Mac a couple years ago, I still use Windows daily and like it well enough, I've used Linux for years and like it also (if not the ecosystem), and I use Chromebook periodically.
There's absolutely nothing wrong with the size of the dots in Mac. I honestly don't see a usability difference vs Windows, except that they (of course!) are on the opposite side.
