In filling out a form, why don't the checkboxes show up until you click on the area where they are located?

Thanks for trying to help. I was able to resolve the problem by going to "settings", "accessibility", "display". By changing the contrast as well as working with the tint, I was able to solve the above problem plus some others like "turning off the printer color button going to white and not visible". I still have to tweak the tint or colors but everything is much clearer. Using "appearance" and "accessibility" under setting, I should be fine. Thanks again.

I'm just trying to fill out online forms for automobile registration, etc. The checkboxes or fill in areas show up once you click on the appropriate spot but determining where they are located requires clicking with the arrow in different spots. This is a problem unique to the MacBook. No problem on the iPad.

No. New computer. I haven't installed anything. I thought it might have something to do with the setting but I can't find any change that helps.
