After upgrading your operating system to the new macOS High Sierra, there may be some settings you will want to see if they were changed or adjusted during the installation. One such setting I recommend is the energy saver.
Recently, I was working on a MacBook Pro and as I looked at the screen, I noticed it was a little dark. I asked the computer’s owner if it had always been that way. I asked them if they would like it to display a little brighter and they thought that would be nice. When I showed them how to change this setting, they were upset that they had waited three years to find it. If you suffer from the same, here is how to adjust it and other related settings.
Go to System Preferences by opening the Apple menu at the top-left and then select Energy Saver.
First, let’s set up your preferences when your computer is plugged in. Select the Power Adapter tab near the top of the box. Here you will move the sliders to your desired position and this depends somewhat, on the kind of computer user you are. If you find you are constantly leaving your computer to attend to other duties, and you often forget to return until hours later, I recommend you checkmark the box: Put hard disks to sleep when possible and also Wake for network access. I also recommend that you move the sliders to put your computer to sleep and to turn off the display, more to the left, so your computer will stop using full energy after your desired time of inactivity.
After you have made your selections, select the Battery tab near the top of the box. I recommend similar settings when your computer is on battery power. However, if you notice, there is a box that when it is checked, it will slightly dim the display when on battery power. If you want your screen to be brighter, remove the checkmark from this box. You will see the difference immediately as you toggle this setting back and forth. Once you have made your choices, select the Show All (the 12 very small dots in the square at the top-left) button and then select Displays.
Here is where you can increase the brightness to its fullest. Make sure that you select the Display tab near the top of the box and then move the brightness slider all the way to the right and remove the checkmark from the box: Automatically adjust brightness. You can also adjust this setting on your MacBook by pressing the brightness key at the top of your keyboard. When you are finished, you can close the System Preferences box.
