I want to use tabs when composing new emails in Apple Mail on my Mac. I searched here and read this question:
The thing is this question says it’s a new feature in macOS Sierra, but I am convinced that in the past I used tabs in Apple Mail. I know it wasn’t in Sierra because my Mac runs El Capitan and has never had Sierra installed.
Did I just imagine this? Was it a dream? Or is this actually possible in El Capitan too?
