Hello
I am encountering issues launching mne-python after a first install on a new MacBookPro.
In Spyder console, the “import mne” command yields the errors message pasted below.
System info:
- MNE version: 1.9.0_0
- operating system: macOS 15,5(24F74)
- Spyder 6
In Spyder, the python interpreter is listed as follows:
/Users/vv221713/Applications/MNE-Python/1.9.0_0/.mne-python/bin/python
Spyder console
- Python 3.12.7 | packaged by conda-forge | (main, Oct 4 2024, 15:57:01) [Clang 17.0.6 ]
Type “copyright”, “credits” or “license” for more information. - IPython 8.17.2 – An enhanced Interactive Python. Type ‘?’ for help.

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
- The Python version is: Python3.12 from “/Users/vv221713/Applications/MNE-Python/1.9.0_0/.mne-python/bin/python”
- The NumPy version is: “1.26.4”
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
