Hello,
I followed the step-by-step instructions for installing O2Physics on my Mac (macOS Tahoe 26.0.1) as described in the official O2 documentation. However, the build consistently crashes during the compilation of ROOT@v6-32-06-alice10 when running aliBuild build O2Physics.
For context, I don’t have any previous ROOT installation on my machine.
I’ve attached the log file for reference.
Thank you for your help,
Ahmad
