Hi Corey,

Have you looked at a newer version? A51 is quite old now. I have heard fewer complaints about A57, which is the most recent version that has been out since June of this year.

Subject: vmd-l: M1 Mac menu issues

Dear list,

The issue of menu items not working for M1 users (VMD 1.9.4a51-arm64-Rev9) has come up a few times (most recently in 2021 ->$>).

Most recently for me, when I use the Extension -> RMSD Trajectory Tool, I can't edit the atom selection and the buttons don't fully work. I have noticed that opening the TK console automatically via the vmdrc magically makes them work again. e.g. in the after idle section:

after idle {

  if { 1 } {

    foreach molid [molinfo list] {

      reset_viz $molid

      menu tkcon on

      menu tkcon move 800 150




Are there plans for a long-term solution with respect to changes made by Apple? Or does this issue prevent a stable MacOS version for ARM CPUs from ever being released?

Cheers all,
