✔️ Top 7 Fixes for Screen Brightness Not Working on Mac
– Reviews News
Apple Mac displays get better and sharper with each generation. Today you get a Super Retina display on your Mac and you can adjust its settings to optimize your display preferences. Brightness is one of the main features of Mac displays.
You may experience screen brightness issues when using your Mac outdoors or in a restaurant. There are times when you cannot change the screen brightness. If you are facing the same problem, here are the best ways to fix screen brightness not working on Mac.
1. Check the automatic screen brightness settings
Your Mac can automatically manage screen brightness based on the lighting around you. If screen brightness isn't working on your Mac, here's how you can check these settings to begin troubleshooting.
Step 1: Press Command + Spacebar in the open Spotlight search, type System Preferences, and press Return.
Step 2: Click View in the lower left corner.
Step 3: Check if the “Adjust brightness automatically” option is enabled. Otherwise, check the box to enable it.
You can also try manually changing the screen brightness from the slider.
2. Check the keyboard function key settings
The F1 and F2 function keys on your Mac keyboard are designed to manually change the screen brightness. But if they were designed to be used as standard function keys, you won't be able to use them to change brightness levels. Here is how to check the same.
Step 1: Press Command + Spacebar in the open Spotlight search, type System Preferences, and press Return.
Step 2: Click Keyboard.
Step 3: In the Keyboard tab, check if 'Use F1 and F2 keys as standard function keys' is unchecked or not.
Otherwise, deselect the option.
Step 4: Close the window and try changing the screen brightness using the F1 and F2 keys.
3. Disable "slightly dimmed display"
While there are other ways to improve battery health on Mac, screen dimming is also something many prefer. Your Mac gives you another option to dim the screen slightly when running on battery power. This is how you can turn it off and see if the problem is fixed.
Step 1: Click the battery icon in the upper right corner of the menu bar.
Step 2: Click Battery Preferences in the context menu.
Step 3: If "Display slightly dim on battery" is selected, click the checkbox to deselect it.
Step 4: Close the window and see if you can change the screen brightness.
4. Restart your Mac
After adjusting the basic settings mentioned above, we recommend restarting your Mac. Regularly restarting your machine can help prevent many software and hardware problems.
Step 1: Click on the Apple logo in the upper left corner.
Step 2: Click Restart.
After your Mac restarts, check if the issue is resolved.
5. Reset SMC
Now let's talk about some advanced solutions if you are still unable to fix the problem. You can try SMC Reset for your Mac or iMac Intel. This solution will not work on Macs based on the Apple M-series chipset.
SMC or System Management Controller is a chip that stores critical information about all the different hardware functions. You can try resetting the SMC as we are talking about fixing the screen brightness issue.
Step 1: Hold down the power button until your Mac shuts down.
Step 2: After your Mac shuts down, wait a few seconds, then press Shift + Left Option + Left Control Key. Also hold down the power button.
Hold down all four keys for another 7 seconds. If your Mac turns on, it will again play the default startup chime as long as you hold down these keys.
When you see the Apple logo, the screen turns on normally. After that, check whether you can change the screen brightness or not.
6. Reset NVRAM
If resetting the SMC didn't work, you can now try resetting NVRAM on your Mac. NVRAM or non-volatile random access memory contains information such as sound volume, boot disk selection, time zone, etc. You can try this solution, which only applies to Intel-based Macs.
Step 1: Hold down the power button on your Mac.
Step 2: After your Mac shuts down, press the power button again to restart it.
Step 3: While your Mac is turning on, press Command+Option+P+R for 20 seconds.
Step 4: Release all four keys when the Apple logo appears a second time. This means the NVRAM reset is complete. After that, your Mac will restart.
5nd step : See if you can change the screen brightness levels.
Note that for Mac models running on Apple M-series processors, the reset option is similar to resetting NVRAM.
7. Update macOS
The last resort for you if nothing has worked so far is to update macOS to its latest version to remove any bugs or issues that are causing this problem. That is how.
Step 1: Click on the Apple logo in the upper left corner.
Step 2: Click About This Mac.
Step 3: Click Software Update.
Step 4: If an update is available, download and install it.
5nd step : Check if the issue is resolved.
