Hi, I run Rhino sporadically on several different machines and one somehow has a command line window sporting a red font which must be at least 20, if not more. How can I change this?

Hello - this is set in Options > Appearance page. -Pascal

[Bildschirmfoto 2025-11-22 um 22.12.53] could not find the options to change font size and color of the command line

Hi Rudi, If you click on ShowAll and then open Advanced page, you can enter “CommandPrompt” to find the related settings on Mac: [CommandPrompt] I’m not sure if there is another way to change the font size and color. _ c.

[Bildschirmfoto 2025-11-22 um 23.45.24] thanks, but i am talking about command history / command line the other settings dont seem to work in RH9

still does not work in RH8 on macOS, only in WIP

Hi Rudi - [image] Rudi: still does not work in RH8 on macOS This is a thread in the “Rhino for Windows” category that was started in 2017. There is no command line in Rhino 8 on macOS and that is not something that will ever change. -wim

Hi Rudi -

Correct. At present, text size and color doesn’t work:
→ RH-88869 Text size of command prompt does not work
→ RH-88525 Command prompt background color not supported
