When you’ve pressed your display brightness down key on your Mac’s keyboard as many times as you can without the screen going completely black, and it’s still too bright for you, then you’re probably like me and need a way to further dim the display’s dimness level beyond the OEM minimum.

In this tutorial, we’ll show you a way to further decrease your display’s brightness when you’re in the dark so it’s easier on the eyes.

Why to dim your display even more

In events where you’re in a completely pitch black room, sometimes the lowest brightness setting for your Mac’s display doesn’t cut it. It still feels like you’re looking into a source of bright light and the ambiance isn’t very appealing.

Moreover, if you have a migraine, every last bit of display brightness makes a huge difference in comfort. Coming from a background of migraines myself, having too bright of a display hurts the eyes and further irritates your head in one of these scenarios, and having a completely dim display just bright enough to see in a pitch black room is the one thing you desire.

How to dim your display even further

Since your display brightness is really a function built into the back-lit display hardware of your Mac, the best and easiest way to get that lower brightness setting that you can’t seem to find is by using an app on your Mac that can add a dark shade overlay over everything you see on the screen to give you the illusion that your display just got darker.

One such app that is free and works great for this is Shady for Mac, which you can download for free. To use the app, follow these steps:

Step 1: Download Shady for Mac from the link provided above and open it.

Step 2: From the Menu Bar on your Mac, click on the Shady icon and take note of the Dark/Light slider.


Step 3: Drag the slider down closer to the “Dark” label and your display will get a dark shade placed over it.


Step 4: That’s it! You now have a simple way of reducing the glare into your eyeballs in a dark environment.

The caveats of Shady for Mac

There are a few things that you need to know about using Shady for Mac because it’s important to realize what this app is really doing.

Although Shady for Mac isn’t technically lowering the back light on your display lower than OEM presets, it is placing a gray overlay atop your entire display so that the colors appear darker. This gives you the illusion of a darker display with less glare in your eyeballs. Since it’s only the display being affected by the changes, and not the LED backlight, you’ll notice that despite the dimmer display, the Apple logo on the back of your MacBook will still shine with the same intensity.

The one major drawback of using Shady for Mac is that the gray overlay being placed over everything means when you take screenshots, they will come out darker than they would without the overlay. Fortunately, if you ever need to take a screenshot, you can just return your display shade to the default before doing so and the colors will be correct when you take the screenshot.

Shady for Mac is a great way to quickly make your display appear dimmer than the lowest preset Apple gives you for display brightness. Although it’s not truly affecting the screen’s brightness, it does affect the color output to make the display easier on the eyes when you’re in complete darkness.

Despite the fact that there are other options out there, such as Sunset ($3.99 in the Mac App Store), Shady is free via the developer’s website and has the basic functionality you might be looking for.

    There are free alternatives on the Mac App Store
    I think one of the best ones is brightness slider, which lets you assign keyboard shortcuts
    I use it to dim my external display, as the regular brightness controls don’t work on it and I don’t want to fiddle with its brightness settings.

    Very timely article. I was using the wired connection on my apple monitor the other night and discovered that I could not completely dim it. Even the lowest setting was too bright so I ended up placing towels over it. I really wanted to email and ask but figured it was such a petty thing that I didn’t bother.

    Thanks for sharing.

      Not a problem!

    OR you could hold down Shift+Option while you fine tune your brightness with the brightness keys.

    • chjode

      Yep, fine tuning for brightness and volume have been around for years.

    • Anthony Bouchard

      After having tried that myself, I didn’t really see much a difference between the lowest preset and the lowest brightness setting using the Shift+Option method. With Shady, you’re going to get your display looking a lot dimmer.

      I don’t know if you guys actually read the article? They are talking about making the screen DIMMER than the dimmest setting. Yes, fine tuning has been around for years. Fine tuning doesn’t let you go dimmer than the dimmest setting.

      I know this post is old, but ignorance KILLS ME.

      • Andres

        But don’t deny that fine tuning can’t get your screen brightness lower than the lowest dimness.

        It can and most people don’t know about it.

        Nit picking at comments in old posts KILLS ME

      • Babayagah

        Actually, no it doesn’t. You need the app to go any dimmer than dimmest. I’m literally trying it right now.

        Your comment was the first one, at the very top. It was ripe for the picking. Take care.

      • Andres

        Weird. Works for me. Same as it works with the volume

      • Axel Lim

        what special mac do you have? because this fine tuning shenanigans sure as hell doesn’t work on neither our iMac or Macbook. If it were possible to fine tune brightness below what is already the lowest setting, you think these guys would have come out with Shady???

  • jalexcarter

    are there any apps that allow you to dim the screen brightness on an external monitor like the apple cinema display that I have? it’s always full blast no matter what brightness my MacBook Pro is at and it can be a bit annoying sometimes

    • Noah P

      the apps mentioned above helped me with my monitor but would love to be able to go completely dark with my MBP’s built-in monitor.

    • :D

      Brightness slider worked for me

  • artemicia t

    oh my god I love you! You cannot understand how helpful this is to me !

  • Chenhan Shao

    It’s kind of hilarious to see, at least in my case, the cursor is still as bright as usual.
