I am trying to run mri_convert (and recon_all) with a Macbook Pro 2019 with Catalina.

Running mri_convert always leads to the following error:

//Users/neurolab/Desktop/Stephan/Programmes/freesurfer/bin/mri_convert: line 3: //Users/neurolab/Desktop/Stephan/Programmes/freesurfer/bin/mri_convert.bin: cannot execute binary file

All security changes haven't helped yet.

Best,

Stephan
