Hi there, vicleone. I’d be delighted to help you. What you can do is go to system preferences, which is under the large Apple icon at the top left of your screen. Then, go to display. Pick one that more suits your ability to see. In addition, if you go to the same system preferences go to accessibility and turn on bold type. If you click on the left side of the finder window where do you see three dots, One is red, one is yellow and one is green. If you click on the green one, it should give you full screen. You can also increase the system font size up to either 14 or 16 points which might help you a bit. I think this is under system preferences then general. You can also connect your iMac to a TV set and use that as a binder which might help you see better. I don’t know your exact model and year of iMac, so can’t say for sure which ports/outputs/jacks it has for that. However, if it’s one of the most recent ones, it’s probably USB-C. So, you’d need are USB-C. To HDMI adaptor and then an HDMI cable to your TV and you can use one of its inputs for that.
