As a Mac user, you're likely familiar with the incredible benefits of True Tone. It automatically adjusts your Mac's screen color temperature to match the ambient light conditions in your room. The result is an adaptive display experience that becomes easier on your eyes by reducing the risk of eye strain, no matter the environment. However, True Tone is not always enabled by default on Macs, so you may need to activate it manually. Thankfully, macOS offers many ways to enable True Tone so that you can easily enjoy its perks.
Good to know: activating True Tone is just one of the many ways that you can improve your Mac experience with macOS Ventura.

4. Enable True Tone Using Apple Script
You can also use Apple Script to enable True Tone in macOS with these steps:

tell application "System Preferences" activate reveal anchor "displaysDisplayTab" of pane "com.apple.preference.displays" end tell tell application "System Events" tell process "System Preferences" click checkbox "True Tone" of tab group 1 of window 1 end tell end tell quit application "System Preferences"
- Click on the "Run" button (or press Command + R) to run the script. If prompted, grant Script Editor permission to control the System Preferences or System Settings app, depending on the version of macOS you're running.
- The script will open the Displays preferences panel and enable True Tone.
If Script Editor isn't given accessibility access on your Mac, it gives an error that says, "Script editor is not allowed assistive access." Continue following these steps to remedy this issue.
- Go to "System Preferences -> Security & Privacy," then click the "Privacy" tab.
- Select "Accessibility" from the options, and click the lock icon in the bottom-left corner.

Frequently Asked Questions
Does True Tone affect color accuracy?
True Tone can somewhat affect color accuracy, but it's not a significant difference. It makes your Mac's screen colors appear slightly warmer or cooler depending on the lighting in your environment, leading to a more natural view. However, True Tone is not ideal for tasks that require precise color accuracy, like when using a video or photo editing app. It's best to disable True Tone for tasks like these. You can also calibrate your Mac's display to take color accuracy to the next level.
Does True Tone increase battery life?
True Tone doesn't directly increase battery life. While it may impact perceived battery life by optimizing screen brightness, its impact on actual battery consumption is negligible.
Is True Tone safe for your eyes?
True Tone can be beneficial for your eyes, as exposure to blue light during late hours has been shown to suppress melatonin secretion, which can negatively impact your circadian rhythm. Adjusting the color temperature of the screen to match ambient lighting reduces eye strain caused by harsh contrasts. The warmer tones can also create a more natural viewing experience, especially in low-light environments.
