Dark mode lightens the burden on my eyes, kind of like a dark room is better for a headache. Though there is no conclusive evidence on whether it’s actually better for your eyes, I find using dark mode decreases eye strain and can also extend your battery life.
How to make Mac dark mode
Step 1: Go to System Preferences
From the Apple menu at the top left of your screen on your Mac, select System Preferences.
Step 2: Click General
On the window for your system preferences, select General.
Step 3: Click Dark
General settings include appearance, scroll bar settings, default browser, and more, so if you’ve never explored these settings, now’s a good time to customize your Mac. When you click on Dark, your Mac’s buttons, menus, and windows will take on a darker appearance. If you choose Auto, your Mac will stay on Light mode and gradually transition to Dark throughout the day. Also read: Using your iPhone in high temperatures can cause permanent damage
