Hi

I installed MNE following the instruction, there is a problem for me.

the ?mne\_browse\_raw? command does not startup, it shows ?attempt to add non-widget child "dsm" to parent "mne\_browse\_raw" which supports only widgets?.

How should I fix this problem?

I am using MacOS Mojave 10.14.4

Thanks for your help

Bo

hi,

I suspect you need the proper version of xquartz

see [https://mne-tools.github.io/dev/install\_mne\_c.html#system-requirements](https://mne-tools.github.io/dev/install_mne_c.html#system-requirements)
