It is very likely that, on some occasions, you have seen some text in some application on your Mac, which you have not been able to read clearly. And is that sometimes this is complicated, especially if you have a computer with a relatively small screen, or if you want to see something at a too compromised distance.
Be that as it may, you should not worry, since Apple includes a solution to the problem natively in macOS as standard, and is none other than the simple zoom, which although it may not seem like it can be very useful on certain occasions.
How to Zoom In & Zoom Out on Mac
Step 1. Place two fingers on the trackpad and :
Zoom in : spread out
Zoom out: pinch
Step 2. Go to the apple symbol → System Preferences → Accessibility → Zoom → Choose comfortable option:
a) Use keyboard shortcuts:
Option(⌥ ) + Command(⌘) + given symbol
Toggle zoom (Zoom in where the mouse is) –
⌥ + ⌘ +8
⌥ + ⌘ + =
Zoom out –
⌥ + ⌘ + –
b) Use scroll gesture with modifier keys:
Options – Control or Option or Command key
Example control key:
Two fingers on keyboard → Control + fingers upward – Zoom in
Control + fingers downward – Zoom out
Step 3. While browsing a window (preview / safari)
(⌘) + (+) → Zoom in
(⌘) + (-) → Zoom out
Use the zoom when you need it
In order to avoid any problems, in order to use the zoom you will have to use a key combination, which is Alt + Command + 8 . When you do this, the option you have chosen previously will be carried out, so if you had selected the full screen, you will automatically see how everything increases, and if you had chosen the image within the image, a small window will appear with the activated zoom, which you can move around the screen as you are interested.
Also, if you want, with Alt + Command + 0, you can zoom around the screen if you want, and when you no longer need it, just pressing Alt + Command + 8 again will disable the function.
