is there a way to make the tool bar larger?
I can enlarge everything so I can see it more easily,
everything that is EXCEPT the tool bars, menu bar, search window, etc.
How can I make all of those larger (more easily seen) ?
You can set the resolution to a lower value to make things bigger. This makes everything universally bigger. Depending on the mac you have, you might could use something called HiDP mode which is a hack you have to do that will make things really big, though you can't fit much on the screen that way.
A little program called resolution tab will let you use HiDP, but it does not persist through reboots.
