Syntax error in thisroot.csh during installation?

I recently installed root_v6.20.04 on my macbook pro (Version 10.14.6) from the website. There I downloaded the “Macos 10.14 clang100” .pkg file and followed the installation procedure which installed it in the /Applications directory. Afterwards I followed the ReadMe instructions to set the correct environment variables by putting the following lines in my .bash_profile:

. /Applications/root_v6.20.04/bin/
source /Applications/root_v6.20.04/bin/thisroot.csh

When I now run root I get this error:

-bash: /Applications/root_v6.20.04/bin/thisroot.csh: line 17: syntax error near unexpected token `('
-bash: /Applications/root_v6.20.04/bin/thisroot.csh: line 17: `set ARGS=($_)'

I doubt the .csh file actually has a syntax error since I didn’t touch it, what am I doing wrong?
Thanks in advance.

Not sure what you mean by that Wile_E_Coyote.

If you are not using the C shell (tcsh or csh), you can simply drop the second line and only source Otherwise, put source /Applications/root_v6.20.04/bin/thisroot.csh in your .cshrc file.
