Potential MacOS 10.15 Installation

Hello, I realized my other thread was based on Ubuntu 20.04 and I finally got that one to seemingly work thanks to your help. I am still having issues on my MacOS. I ended up uninstalling everything, and following the directions from another thread here with MacOS 10.15 (Uninstalled anything with afni under root, reinstalled under my user account, and installed R 3.6.3 since 3.6 is supposed to be best for the necessary packages). I think I have most things worked out but I still have a couple potential errors (?) popping up:

=========================  summary, please fix:  =========================
*  login shell 'SHELL_NOT_DETECTED', trusting user to translate code examples from 'tcsh'
*  OS X version might be old
*  consider setting DYLD_LIBRARY_PATH to /opt/X11/lib/flat_namespace


does give the /opt/X11/lib/flat_namespace, but


does not show it as a variable… I have tried the


command and everything I can think of, but it does not seem to stick as an environment variable showing on


Thank you!

The default shell for new users is Zsh (Z-shell) on Mac OS 10.15, Catalina. We have really only supported bash or tcsh configurations so far, so you would have to modify our installation scripts for Zsh if you if you want or change your default shell to bash or tcsh (which seems easier).


I think zsh has been mostly supported for a while, but there may be a couple of shortcomings, as noted here. I keep forgetting to fix the shell detection, but will see if there is a machine that I can use to do that soon.

Thank you! That is helpful. As a side question, if I make a post, but then figure it out later, is there a way for me to close the discussion or delete my post? I don’t mean to keep throwing too many questions at you all, especially if I manage to work it out later. So far, I have only found a way to edit posts, but not delete or “close.”


It is actually most preferable for you to post your own solution. One of the main uses of the board is for people to search through the messages.
