How to Increase the Text Size on Your Mac

1. Click the Apple icon in the top left corner.
2. Select System Preferences.
3. Select Displays.
4. Click Scaled.
5. Select a lower resolution. If you see icons with different sized previews of text, select the icon that says Larger Text and click OK.

Another description of this fix, adjusting the resolution on your screen, appears on this Apple Support page:

On your Mac, choose Apple menu > System Settings, then click Displays in the sidebar. (You may need to scroll down.) Select the display you want to adjust, then select the resolution you want to use. You may be able to turn on “Show all resolutions” to see additional resolutions for the display.

Depending on how you adjust the resolution, some app windows may not fit entirely on the screen. Using a scaled resolution may affect performance.

In the alternative, you could hook up a separate monitor to your Mac.
