Running AFNI and SUMA on a mac (OS 10.15.6).
I can get SUMA and AFNI both to open just fine, and load up the relevant datasets in AFNI. NIML+PO is selected, SUMA recognises the TT_N27 spec and sv files and I get the 3d brain image to play around with, but when I press 't', nothing happens.

This happens both with my own data, but also in the suma_demo folder from the bootcamp data.

I'd be grateful for any help.

If it's relevant (although I can't see offhand why it would be), I'm trying to do this through TeamViewer. I have not had any other problems with inputting commands, though.

Output of the SUMA terminal window:

LanguageLab$ suma -spec TT_N27_both.spec -sv TT_N27_SurfVol.nii
