I'm using the "FLATLAF_DARK" theme + customized colors, on macOS 14 Mojave in dark mode. It works ok but the main titlebar of the window is not dark. Is there a way to do that?

In the github page of "JDownloader-2-Dark-Theme" by Vinylwalk3r (**External links are only visible to Support Staff****External links are only visible to Support Staff**), there is a screenshot of JDownloader2 with a dark title bar, exactly what I want, and instructions to run this command to get it:

defaults write org.jdownloader.launcher NSRequiresAquaSystemAppearance 0

But I can't get that to work, and there's an unanswered bug report there that it doesn't work, since May. I also tried:

defaults write org.jdownloader.launcher NSRequiresAquaSystemAppearance false

and after reading Apple's developer note here: **External links are only visible to Support Staff****External links are only visible to Support Staff** putting this into the info.plist of the JDownloader2 app bundle:

<key>NSRequiresAquaSystemAppearance</key>
<false/>

and I also tried doing the whole installation of "JDownloader-2-Dark-Theme". But nothing works.

I did find the "LAFSettings: Window Decoration" setting that gives a custom dark title bar, but that looks very strange on a Mac and is not what I'm looking for.

Any ideas?

I tried again adding NSRequiresAquaSystemAppearance false to the info.plist, and this time it worked. Don't know what's different, but I have a nice dark titlebar now!

Thanks for the feedback! It should also work fine with manual settings the value via defaults command
I've updated JD to autoset this property with next core update

I can confirm that the "defaults" command now works, without needing to edit the info.plist file, thanks!

defaults write org.jdownloader.launcher NSRequiresAquaSystemAppearance 0

Latest JDownloader Update does this automatically for MacOS Mojave and newer

Fyi, now I know what was different: I installed AdoptOpenJDK 8 for something else, and JDownloader started using that. Oracle's JRE/JDK (any version I install) doesn't work, it gives the white titlebar regardless of the setting. Same for Zulu's OpenJDK, it doesn't work either.

On the other hand, I just tried a new install on another machine with Big Sur, and it does get a dark title bar with the bundled JRE. So I don't know what that's about...
