Intellij Idea, open new project creates a new tab for each project, how do I revert to a default of a new window per open project?

Question

If I open a new project in Intellij Idea it now opens it as a new tab. How to change the default behaviour, revert to the previous behaviour and open in a new window?

Answer 1

In macOS System Preferences | General, set "Prefer tabs when opening documents" to "Never".
