Dimsome for Mac.

A warmer, dimmer Mac in the evening, pure red by the time you choose, with the backlight at full power so the screen does not flicker.

Quiet until evening.

Dimsome sits next to the clock and works in the background. After you wake it brightens over 4 hours. In the afternoon a 4-hour fade starts, so your Mac is pure red at the time you choose. It happens so slowly you never notice the change, only the result.

Not just Night Shift.

Night Shift is free and built into macOS. It warms the screen to a mild amber on a sunset schedule, and stops there. Dimsome goes all the way to pure red, fades over hours instead of minutes, follows your wake time instead of the sunset, and keeps the backlight at full power so it does not flicker. Read the full Dimsome vs Night Shift comparison.

Your brightness keys still work.

With the flicker guard on, the brightness keys turn the picture down instead of the backlight. Same control, no backlight switching on and off. External screens are set to full brightness when they allow it. More on screen flicker.

Made for work too.

Editing photos or checking colours? Pick the apps Dimsome skips, and those windows keep their true colours. Screenshots, screen recordings and video calls show normal colours to everyone else.

Install in five steps.

  1. Get your key on dimsome.app. It shows up right away and comes by email.
  2. Download the Mac zip, open it and drag Dimsome into Applications.
  3. The first time, macOS asks before opening it: go to System Settings, Privacy & Security, and choose Open Anyway.
  4. Enter your key. The Way of Life mark appears in the menu bar next to the clock.
  5. Set your wake time and the time you want the screen red. Dimsome does the rest.

What people ask.

Does Dimsome work on Apple silicon and Intel Macs?

Yes. Dimsome runs on macOS 13 Ventura or later, on both Apple silicon and Intel Macs.

Why does macOS ask before opening Dimsome?

This first version is not yet notarised by Apple. Go to System Settings, Privacy & Security, and choose Open Anyway once. A notarised version is on its way.

Can I use Dimsome with Night Shift on?

You can, but you do not need to. Dimsome goes further than Night Shift, so most people turn Night Shift off.

Does it work on external monitors?

Yes. The colour filter works on every screen. The flicker guard sets external screens to full brightness when the screen allows it.

Tonight can look different.

Get your key, set two times, and let the evening come to your screen slowly.
