Hello Kiryl,

Yes, we'll be improving the dark mode in the next versions.
Unfortunately, Apple decided to make this option system-wide.

But there is a standard workaround.

1. Quit the Valentina Studio
2. Run Terminal.app
3. Execute
defaults write com.paradigmasoft.vstudio NSRequiresAquaSystemAppearance -bool yes

4. Start the Valentina Studio - now it should have a light appearance.

For some reason (I think it is related to preferences cache), it didn't work for me at first, but now it works flawlessly, the appearance is switched.

thank you ! worked perfectly.

Please keep try newer builds,

VStudio team constantly improve dark theme
