macOS can't control external monitors brightness natively. Lunar adds that capability so you can use the same familiar brightness keys to adjust all monitors at once, or fine tune each one.
Volume keys also work for adjusting monitor volume, and there are hotkeys for switching between monitor inputs/ports.
By using the MacBook and iMac integrated Ambient Light Sensor, Lunar can automatically adapt your monitor brightness and contrast throughout the day so you can forget about fiddling with buttons.
Even if you have monitors with different brightness capabilities, Lunar can learn the differences between them and compute a custom brightness curve for each one so they're always at the same perceived luminance.
Displays that have more than 500nits of brightness are limited by macOS so they can't reach their full brightness. Lunar unlocks that through its XDR Brightness feature so you can work in sunlight.
The Sub-zero Dimming feature allows you to lower the brightness below the usual 0% so you can work comfortably during the night.
Lunar's BlackOut feature can turn off individual displays (even the built-in MacBook display) so you can focus on single tasks:
Adaptive Brightness
Native Brightness Control
XDR Brightness
Dim brightness below zero
Switch monitor inputs
Sync brightness between displays
Turn off individual displays
External light sensor support
Scheduled brightness presets
Command-line integration
Promote Lunar.fyi. You can add any of these badges on your website.
Have you ever felt down? Depressed? Like there's something missing?
That's computing life before Lunar. You might still be depressed, but at least you'll feel control over your displays.
Facelight, smart brightness sync across monitors, support for a DIY-ish light sensor, command line integration, APP SPECIFIC PRESETS (!) the ability to access the XDR brightness in your shiny new Macbook, and much more.
Your screens deserve better, your eyes deserve better. There's simply no better way to manage how light gets into your eyes from your monitor.
We have collected here some useful links to help you find out if Lunar.fyi is good.
Check the traffic stats of Lunar.fyi on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of Lunar.fyi on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Lunar.fyi's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Lunar.fyi on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

I had a similar issue, but I chose to solve it another way. I connected both computers directly to the monitor and used lunar[0] to use a keyboard command to switch inputs. I then used a Deskhop[1][2] to share the KB and mouse between both computers. It sounds awful, but in practice it was surprisingly nice. My monitor (LG Ultragear+) switches inputs fairly quickly. The process was something like this: hit the... - Source: Hacker News / 4 months ago
Damn, I use Sourcegraph so much for my reverse engineering efforts on macOS. They index all those private framework symbols that people extract on every macOS release, and allow searching for headers and even how they are called by other developers that were ahead of me. A big part of https://lunar.fyi exists thanks to Sourcegraph search. Even now I'm using it to find a way to enable the second monitor on M3... - Source: Hacker News / about 1 year ago
Itโs done in a similar way on macOS: a dylib is added to the bundle and an LC_LOAD command is added to the app binary. The dylib is the first thing that runs because of using the constructor attribute, like this: https://notes.alinpanaitiu.com/Injecting%20a%20DYLIB%20into%20a%20macOS%20app The nice thing is that a signed app will refuse to load a dylib that does not have the same signature. So crackers will be... - Source: Hacker News / over 1 year ago

Wild! I am working on exactly the same thing now for Lunar (https://lunar.fyi), and I'm also calling it Night Mode ^_^ what a coincidence I've been trying to make "white regions in dark backgrounds" less painful for months, but doing that at the system level on macOS is incredibly hard. I see you're doing it with CSS filters, which make sense in the limited scope of an article. But applying something like... - Source: Hacker News / almost 2 years ago
I was comparing anti-piracy measures with DRM, I don't have actual DRM in my app. I can't block users that really bought the app from using it (which is what DRM is notorious for). But I do have a license verification for the Pro features (https://lunar.fyi/#pro), and that is what people are cracking in the app. I only added more protection around this verification. - Source: Hacker News / almost 2 years ago
I believe in most cases, DRM would not exist if people wouldn't have started pirating digital content. We're also to blame for the state of things. Just like I would not bother to buy and use a bike lock if people would not steal bikes in the first place. It's a bad analogy though, like all analogies are, since if I sell my bike I can't make it stop working for the buyer at a later time. But that's the big... - Source: Hacker News / almost 2 years ago
There's no Reduce White Point on Mac as far as I am aware. However, you can use the fantastic Lunar [0] app to achieve this, as it supports "Sub-Zero Dimming". To use it, I think you just need to start Lunar, and then press the Reduce Brightness button on your keyboard until it goes below the minimum Mac allows.

As the dev of a macOS app that breaks all the time because of external hardware, the tone of the article hits close to home. (Iโm talking about https://lunar.fyi/ whose brightness control commands can be blocked by USB-C hubs, โsmartโ monitors, too long cables etc.) I had to disable public GitHub issues on the app repo [1] because people seemed to fuel each other with spiteful comments and โwhy canโt you... - Source: Hacker News / almost 2 years ago
Last year I bought a second computer for my music studio. I wanted to use the same set of 2 monitors and wired keyboard + trackpad on both machines. I wrote simple scripts to switch my monitor inputs with keyboard shortcuts (even simpler with Lunar, amazing new Mac app โ https://lunar.fyi), which saved me from having to press annoying input-source buttons. But I couldn't for the life of me find a simple, suitable... - Source: Hacker News / about 2 years ago
Some people like the process of writing code, more than the end result. I had a few months of that feeling, but nowadays itโs rarely about writing for me.

One less known use case for this is creating animated UI demos, which as a dev I find harder to do using video editing software.

I have a Dell (u4021qw) that has a built in kvm using the buttons on the back of the display is awful. But it can be controlled via software. Dell makes a tool, Dell display manager, that you can set a keyboard shortcut to control the kvm. That software was kinda awful on Macs, so I switched to Lunar and that tool app works great.
