Is root running on MacOSX 26?

It seems to fail on my machine

As usual, thanks for your help!

Hi @cpruneau,

Thanks for your question. We regularly test ROOT releases on macOS 26.

Could you provide a bit more context about what is not working? Are you trying to build ROOT from source, or are you using a precompiled ROOT release? Could you share some logs/errors that you see?

I had the same issue yesterday when MacOS updated to 26.5. The newer ROOT releases (6.38 and 6.40) should compile OK without any tweaking.

Note that the TF1 constructor has been significantly changed in 6.40, so if you have older codes that rely on TF1/2/3, 6.38 would be the safer choice. I found this out the hard way :upside_down_face:
