WHICH VERSION OF TEAMVIEWER DO I DOWNLOAD - URGENT QUESTION

Serengeti

I have a once-off only need for Teamviewer; a client wants to connect with me. So, I don't need to buy it and I never use it otherwise.

I have a mid-2010 MacBook Pro, with macOS Catalina 10.15.7 ; Which version of Teamviewer with WITH ID AND PASSWORD can I download FOR FREE?
