    The error message indicates you do not have permission to write to the specified location.  We suggest you save the license file in one of the three default locations, your home directory, /Library/gurobi or /Library/gurobi811.  Although it is allowed, saving the license file to a non-default location can be error prone.  Please read the documentation in the following link to learn more.

    Correction:  The error message

    -bash: ./grbgetkey: Permission denied

    indicates you do not have permission to run grbgetkey.     Please check your permissions

    ls -l

    to change permissions to execute run

    chmod u+x grbgetkey

    Did you install Gurobi as SU?  You many need to change other file permissions too.

    When I open the gurobi, the command window shows up with following commands:

     

    -bash-3.2$ exec gurobi.sh

    -bash: exec: gurobi.sh: not found

    Please try

    which grbgetkey

    this will show us where grbgetkey is located.

    then execute the following, replacing <grbgetkey directory> and <directory of the symbolic link> with the directories shown from the which grbgetkey command

    ls -al <grbgetkey directory>
    ls -al <directory of the symbolic link>

    Please post the results.

    It doesn't work

    -bash-3.2$ which grbgetkey

    ./grbgetkey

    -bash-3.2$ ls -al <./grbgetkey directory>

    -bash: syntax error near unexpected token `newline'

    -bash-3.2$ ls -al ./grbgetkey directory

    ls: directory: No such file or directory

    -rwxr--r--  1 xhs  staff  0 Sep 23 19:18 ./grbgetkey

    -bash-3.2$ ls -al directory of the symbolic link

    ls: directory: No such file or directory

    ls: link: No such file or directory

    ls: of: No such file or directory

    ls: symbolic: No such file or directory

    ls: the: No such file or directory

    -bash-3.2$

    This looks strange to me:

    -rwxr--r--  1 xhs  staff  0 Sep 23 19:18 ./grbgetkey

    You should be running the grbgetkey that is typically in /Library/gurobi_server811/mac64/bin/

    1. Can you tell us a bit about how you installed Gurobi?
    2. Did you move any of the files once they were installed?
    3. Is Gurobi installed in /Library/gurobi811/mac64?

    In any case, I'd suggest at this point that you reinstall Gurobi as it appears that there is a problem with the installation.
