Within some applications, such as a browser, you may change the size and style of the font.
An example, such as it is, in Firefox browser you can set various parts of a web page to be
larger or smaller, and this may be tedium to get the part you want larger while not affecting
any other sections. By default, these changes should stick and not just in one session.
If your display does not support a variety of resolutions, the idea may not be adequate to
to change those settings; of course that would be system-wide and last between startups
not just for one session or in one application. Results may vary, especially should your
hardware not give you (m)any choices. The view options in Accessibility may be worth a
look, but I didn't see anything there that'd help me make system-wide text enhancement
across all applications, and systems if so desired. Some that could help, such as file title
size (Finder view preferences) are in different locations in the OS. Or in each Application.
Did you mention which OS X version your computer is using now? Settings vary in them.
Can't say as there is an easy answer. Some abilities to adjust settings are less than ideal.
And in previous Mac OS and Mac OS X, some were approaching a now-lost perfection...
Short of a knowledgeable understanding of command-line effects on the OS X, and how it
also may really mess up the Mac if you choose to randomly try terminal access, no great
or simple system-wide Preference allows the degree of changes one with visibility issues
may require. To employ a floating magnifying glass, does not resolve the greater issue.
There may be a way to custom set some of these items, without using terminal; however
the few I'm aware of that can change system settings are third-party tools such as onyx
or cocktail. And they require admin access. Some of these can really mess things up, too.
In any event...
Good luck & happy computing! 🙂
