    Could it be that this app or website no longer exists? Safari suppresses them with a message indicating that the connection is not secure; the page with (missing content) is also not displayed under Windows.

      Yes, the SSL certificate no longer exists and you are suddenly redirected to a strange page if you only prefix http instead of https. It doesn't look serious to me ... I wouldn't buy anything or enter my email address. The app may actually have been discontinued. I'll see if there is an alternative to LightsOff. Then I'll add it here!

  2. Uwe says:

    Sorry, I've found it in the meantime. With http instead of https you are on the page redirected, there you can download the app.

  3. Uwe says:

    Okay, thanks, I'd rather not install.

    • sir appleot says:

      Yes, I can't say whether it's really something dubious. But I personally do not access such strange occurrences of the websites and rather keep my hands off them.

    Hi all!

    Maybe this could be an alternative:

    I can't say whether this is a verified Apple developer / notarized app. The website promises not to collect any personal data ... how much you can / would like to trust it is up to you.

    • sir appleot says:

      Hi Dirk! That looks good. With the app, dark mode can also be switched on and off based on the app. Exactly what LightsOff did. Thanks for your recommendation.

  5. Uwe says:

    Yes, thanks for the tip. The only problem I have is that after closing the defined app it does not switch back to the original mode (dark for me). This then has to be done manually again.

  6. Uwe says:

    After restarting the Nightshade app, the automatic switchover works.
    Perfect, thanks for the tip :-).

  7. Uwe says:

    I found another alternative (Gray), in which only the respective app window is changed to light or dark mode. The menu bar remains in the mode configured via the system. With NightShade I occasionally had the problem that the Finder would jump back and forth when switching windows. I was only able to fix it by forcibly terminating NightShade.
