Hi,

I installed a few weeks ago last 12.6 version of macOS Monterey, which
notably ships Safari 16. Since then, web sites are randomly displayed
in dark mode. I do not understand why, neither what triggers their
suddenly opening in dark mode.

For instance, I'm navigating in a web site fine in clear mode, and click
on a link of the same web site domain to open it in a new tab.
Sometimes it opens in clear mode, and sometimes in dark mode. If I
copy/paste the URL of the tab which opened in dark mode into a new fresh
tab, it always displays in clear mode in that new tab.
Very very weird.

Yet, I made sure that in my System Preferences > General, the default
appearance is "Clear mode".
I've never used dark mode on my computer. And since the last update, it
is suddenly randomly happening with Safari (never with other apps).

Do you have any clue about what could be happening? And what should I
check to fix that?

Do you mean "Light Mode"? There is no "Clear Mode".

It's possible the particular website(s) in question have their own dark
mode settings. You didn't mention the specific website though, so we're
left guessing.

Julien,

Have you checked your System Preferences -> Displays -> Night Shift?
Turning Night Shift schedule to off may provide you some relief.

Hi Jolly Roger,

Yes, I mean "Light Mode", sorry for the wrong term in English.
I'm using a French localized version in which it is "Mode d'apparence :
Clair".

In fact, it happens on every web site, randomly. Sometimes Amazon is in
light mode, sometimes in dark mode; same thing for web sites like
Vinted, Google search engine, GitHub, etc. They almost always are in
light mode but sometimes they open in dark mode; I close the tab in
Safari and open another one in which it becomes in light mode.

Very strange, and I do not find any bug report about that (seems like it
is not a general bug).

Hi David,

I've just checked: Night Shift is always active (I set it from 03:00 to
02:59) so that I have a continuous blue-light protection.
It has been set like this since several years, without any issue of Dark
Mode, appearing only in Safari by the way (I have tried Firefox in
parallel, which did not show pages in Dark Mode, at least during my tests).

I disable it for today, just to be sure.

Unfortunately, the issue with Dark Mode in Safari is still here, even
with Night Shift disabled :-(

Turn on Dark Mode
Choose Apple menu  > System Preferences, click General, then select one
of the Appearance options at the top of the window:
Light: Use the light appearance.
Dark: Use the dark appearance.
Auto: Automatically use the light appearance during the day, and the
dark appearance at night.

Turn off automatic and use light to avoid switching.

HTH, Joerg

Night Shift has nothing to do with this.

Hmm... Does Safari have built-in Dark mode support? I've used the Dark
mode Safari extension for years and wasn't aware Safari had that
functionality built in:

I don't think that controls website content though - at least I've never
seen it change how websites render on any of my Macs.

This extension does more than the built-in Dark mode support according
to its description (5 different themes, easy toggling...) so it is still
worthwhile having.
In my case, I'm not using any extension, and I am facing issues with
latest Safari 16 only (maybe the next version will fix something, I hope
so).

I do not have experience with the dark mode. To be honest I hate the
dark mode everywhere and at anytime. I never had this issue neither with
Safari nor with the Mac OS itself.

Just to tell you that I'm happy to see that Safari 16.1 fixed that very
annoying bug.
