No I'm not able to change my default shell to fish shell

Question

I am on Mac 10.13.6

I have read this long thread and the 10 working solutions there

How to set my default shell on Mac?

but nothing works for me.

Here is what I've tried

brew install fish
sudo vi /etc/shells
Add line '/usr/local/bin/fish' and save the file
csh -s /usr/local/bin/fish
press ⌘ ,
Shell Open with
Command complete path '/usr/local/bin/fish'
Go to system preferences
Users and Groups
select my user
click on lock icon and enter root password
go into advanced options
change Login Shell to /usr/local/bin/fish

Now I reboot the machine and run terminal. and still it uses BASH.

Answer 1

I ended up solving this myself. thanks to Mankarse for giving me the hint.

Here is the solution

Click on ⌘ ,
Click on Profiles
Click on Shell
Now uncheck the "Run Command"

In my case the Run Command was still pointing to bash. This is my fish was not working.
