Importing ROOT on macOS Sequoia 15.0

ROOT
1

Hello, I’m trying to create a Conda environment on my Mac (macOS Sequoia 15.0). I’ve encountered some problems finding the right versions of Python and ROOT to import. Than I finally came across a question in this forum (“Root got error with anaconda”, unfortunately I can’t attach the link because I’m a new user) from someone who got my same error and I followed his advice to install Python 3.10 and root 6.30.4 for Sequoia 15.0. So I created my environment (conda create --name pyroot python=3.10) where I installed python 3.10 and root 6.30 (conda install -c conda-forge root=6.30.4). Now I get this error when I try to import ROOT:

import ROOT

I thing it is related to Xcode tools, but I’m not sure. Can someone please help me? Thanks in advance for any suggestions.

Cheers

Dear @Chiara_Di_Blasi ,

The new update to MacOS has brought changes that we have to adapt. The conda environment seems to be affected. I am trying to investigate the situation, I still don’t have an estimated timeline for that. I will keep you updated.

Cheers,
Vincenzo

Which Command LIne Tools version do you have ? 16 ? You can find it with:

pkgutil --pkg-info=com.apple.pkg.CLTools_Executables

Thank you for your answer. I tried to do some histograms yesterday, ignoring the error I get importing ROOT, and it seemed to work. However, I will wait for further explanations on this.
