Trial on MacOS

Hi there, 

I am new to Stocks. 

Now I attend a Training Course. 

I just Downloaded the VolFix App for my MacBook. I will get a Windows PC later eventually. 

I logged in with my trial Acc. And Connected to my DEMO CQG. 

I still cannot open a single Chart nor do I even see the Buttons for opening one.

I also can't see the whole settings. 

Is that a Problem with MacOS? Or is it a Problem with the trial, that I have a LITE Version?

I really need Help.

Do I just have to get a Windows PC?

Best Regards
