DarkAdapted is an application program. It controls the amount of red, green, and blue in your screen gamma so that you may, for example, preserve your dark adaptation while using your computer. Gamma fades can be scheduled, AppleScripts may be scheduled, and system-wide hotkeys can be set up to execute AppleScripts and gamma fades.

DarkAdapted is being used by astronomers, planetarium operators, graphics professionals, medical professionals, airline pilots, air traffic controllers, and others worldwide to provide flexible, dynamic control over their monitor's screen color response.

What's New

Version 3.0.1:
  • New: DarkAdapted Pro: When changing between percentage and raw value displays using [tab] followed by [spacebar] in the Control Window, all Control Windows on all screens change to reflect the new type of display.
  • Fixed Control Window bug where tabbing to change Gamma values would only work when pressing [enter] and not when [tab] was pressed to move to the next field.
  • more...

I was in touch with the publisher for a few years. I'm sorry to tell you that he passed away last year. I just found out.

Are there any decent alternatives to this app, since it can no longer be downloaded??

I agree. This is fabulous software. However, the publisher's website is down so there's no way to purchase either a standard nor pro license. I would love to if I could, though.

I have downloaded the trial version and really like it. However, it seems that the developer is no longer supplying serial numbers for purchase. I would love to buy one. If the developer sees this post, please tell me how I can activate Darkadapted.

DarkAdapted 3.0.1 Pro is a recent update from AquilaDigital. I use the Macintosh version exclusively in my telescope observatory to help maintain my night vision while observing. The ease by which i can set my monitor screen to different intensities of red helps me use various programs ((such as “Where is M13”) when i host star parties and someone wants to know where a particular object is in the Milky Way relative to the Earth. Several programs do not come have the option of displaying a night adapted window, and so having a program which allows you to change the monitor display characteristics on the fly is extremely useful. It comes preset with various intensities of red or green, but a simple slider interface allows you to modify the monitor color quality and intensity to any value you want Another plus is that it comes with concise well written documentation which makes learning how to use it a breeze. I can say this is money well spent; it is the cat's meow!

When I retired and switched to a 27" IMAC, the screen was way to bright after dark with the room lights dimmed. This app works very well.

It is well supported by the developer...I sent him an email asking for a key combo for an activity I will do often, and within an hour he emailed me back asking if I wanted a link to the updated app.

Even with the standard version, I was quickly able to create and save some presets, using just the menus and not reading any 'how to,' with the normal amount of trial and error.

[About these stars: I was not able to change a rating, and it would not let me leave one blank! I HAVE NO IDEA AS TO STABILITY YET.

Great product. I've tried multiple screen-dimming apps and DA is the best I've used. This new beta seems to address some of the "ease-of-use" issues I've had with it (specifically dealing with its preferences) and a few kinks still need to be worked out, but it's definitely worth the price for those who need it.

This file attempted to delete contents of my Applications folder. I lost Firefox and Address Book before I killed the installer.

Be careful.

The installer doesn't remove *any* files on installation. It places anything it moves into a "Moved By Installer" folder in the DarkAdapted Folder, and doesn't touch anything it can't move. So the original poster should look for a folder named "Moved By Installer" that contains archives of anything missing.

I'll have a new version up later today that performs additional error checking, but the existing build should be fine for those who install to a subfolder (the default) and not to the Applications folder itself.

Version 2.3.6fc1:

.... If no significant issues are reported, this will become DarkAdapted 2.3.5 final.

I hope not.
