How to Magnify (Zoom) your Computer Screen
This ad-free website's biggest source of support is when you use any of these links to approved sources when you get anything, regardless of the country in which you live. Camera boxes are not sealed, so never buy at retail or any source not on my personally approved list since you'll have no way of knowing if you're missing accessories, getting a defective or damaged customer return or a used product. Buy only from the approved sources I use myself for the best prices, service, return policies and selection. Thanks for your support! Ken.
My son Ryan taught us this one back when he was about 3 years old. It's easy to zoom-in your computer screen, which I use all the time as I want to see details in anything in any image or text in any app. This magnifies whatever's on your screen; of course you'll need to scroll around a much larger image or zoom out to find your menu bars again.
Here's how you set it up:
Click the Apple in the upper left menu bar.
Click System Preferences.
Click Accessibility, the blue circle in the lower right.
Click the box for "Use Scroll Gesture with keys." Leave it at "Control key."
Click the red dot on top left of that box to close it and you're done.
Now to zoom in, hold the CONTROL key and scroll up or down, and the screen zooms in and out.
To scroll with the Magic (wireless) Mouse, move a finger up and down while holding CONTROL. With a trackpad, move two fingertips up or down while holding CONTROL. With the Apple Mighty Mouse (USB with the track pea), hold CONTROL while spinning the pea up or down.
This works exactly like this on OS 10.9 Mavericks and OS 10.10 Yosemite. I've been doing the same thing since about OS 10.4 and I'm sure it's been around long before that; just that it might be different clicks to enable it.
Once you've enabled it, you're good forever. You don't have to go back into preferences ever again; just hold CONTROL and scroll.
Flick all the way down to zoom back out to normal.
This works on all Macs, desktop and laptop.
To do this on Windows, turn in your computer at your local police department or firehouse and buy any Mac. Even the cheapest base-model iMac, MacBook Air or Mac Mini today works flawlessly for everything.
