Is it possible to change the size of the main toolbar (letters size)? The size letter is too small for me, it's hard to know what it says and it would be great to have a bigger letter.

You can in effect change the screen resolution...

If you're referring to the Menu bar

the answer is no.

No. However, an eye exam and current prescription tailored to computer screen usage (as I have) could go a long way to making that menu bar text quite legible, without having to degrade the expected usability through screen resolution adjustments.

I've had to reduce the resolution of the screen a bit, disabled transparency and increase contrast to make it easier on my eyes. Additionally, the Dark Mode had been a huge improvement for me.
