Hi @qq_pp ,

you seem to have a broken environment or a broken ROOT installation, likely because of a MacOS version update that happened after ROOT was installed.
How did you install ROOT? Can you try removing this installation and installing a ROOT package that fits your MacOS version? You can use our pre-compiled binaries or use the conda or homebrew packages, see Installing ROOT - ROOT .

@Axel might be able to provide more insight.

Cheers,
Enrico
