   This issue might be a duplicate of existing issues. Please check:

   • TUI themes became dim #4043: TUI themes became dim (themes dim in default macOS Terminal, similar macOS Terminal rendering issue)
   • 1.0+ is unusable in non-truecolor terminal #3671: 1.0+ is unusable in non-truecolor terminal (visual corruption in Terminal.app on macOS, broader terminal compatibility issue)
   • Input text is black on black #4461: Input text is black on black (theme rendering issues in stock macOS Terminal.app with Pro color theme)

   Feel free to ignore if none of these address your specific case.

   @Raviguntakala this is because of how colors work on old mac terminals. They fixed their lack of support for truecolor on macos 26. If you upgrade your OS this works

   I was able to fix this by telling Terminal to declare its terminal type as "xterm-256color" in Profiles -> Advanced -> TermInfo. I'd previously had it set to "xterm".
