Enable the "Auto-adjust brightness" function to make the brightness change with the ambient light. 4. Use the "Night View" mode to reduce blue light to protect your eyes. 5. Developers can use AppleScript to automate brightness adjustments.
How to adjust screen brightness on macOS? Simply put, you can use the brightness adjustment keys on the keyboard, or fine-tune it through system preferences. Let's take a deeper look at this process, combining some personal experiences and tips.
Adjusting screen brightness on macOS is actually a very simple thing, but if you like to adjust screen brightness in different environments for the best visual experience, it is particularly important to understand some subtle adjustment methods.
First of all, the most common method is to use the brightness adjustment keys on the keyboard. On your keyboard, you will find two keys with sun icons, usually located on the F1 and F2 keys. Press and hold these keys to quickly increase or decrease screen brightness. This method is very intuitive and is especially suitable for use when you need to quickly adjust the brightness.
However, sometimes you may need more granular control, and you need to rely on system preferences. Click the Apple icon in the upper left corner of the screen, select System Preferences, and then select Monitor. Here you can drag the slider to adjust the brightness. The advantage of this approach is that you can see the real-time effect of brightness changes and make more subtle adjustments.
If you often use your Mac in different environments, such as from bright offices to dim cafes, you may find the automatic brightness adjustment feature very useful. In the Monitor settings, you can enable Automatically adjust brightness so that your Mac will automatically adjust the screen brightness according to ambient light. This feature sounds great in theory, but in actual use I find that it sometimes adjusts too frequently or not accurate enough, so I usually adjust it manually.
Another thing to note is that if you are using an external monitor, the method of adjusting the brightness may vary. Usually, you can adjust the brightness through the physical buttons on the monitor, but if you are using a USB-C or Thunderbolt-connected monitor, sometimes you can find the corresponding option in the Mac's Display settings as well.
During the use, I also found some tips. For example, if you think the screen is too bright, you can try using Night Shift. This mode not only reduces blue light, but also makes the overall screen look softer and helps protect the eyes. Enable Night View mode can also be found in the Monitor settings.
Finally, if you are a developer or designer, you may need to test your application or design at different brightnesses. At this time, you can use AppleScript to automate the brightness adjustment process. Here is a simple AppleScript example that allows you to quickly switch to a preset brightness level:
tell application "System Events" tell dock preferences set the brightness to 0.5 -- Set the brightness to 50% end tell end tell
This script allows you to adjust the brightness through shortcut keys or other automation tools, which is very convenient.
There are also some potential issues to be paid attention to when adjusting the screen brightness. For example, if the brightness is set too low, it may affect the readability of the screen content; if it is set too high, it may cause eye fatigue. Therefore, it is very important to find a brightness level that suits you.
In general, there are many ways to adjust screen brightness on macOS, from simple keyboard shortcuts to more refined system settings to automated scripts, all of which can meet the needs of different users. Hopefully these methods and tips can help you find the most comfortable screen brightness in various environments.
