Hello,

I installed the last version of FreeFem++ yesterday (V 4.7).  
When I put a plot in my program no window appears any more to show the figure and the program stop running. Is there someone who could help me to fix this problem please?

Thank you.

Nabil

Do you think that’s a problem related to my Mac version (Catalina 10.15.6)?

Most probably. You are using a very recent Xcode version that (I think?) none of us, the developers, are using. We will see the same problem with the official release of Big Sur, I guess?

Not yet. Use `savevtk` + ParaView.
