Answer by NM Pennypacker for How can I make Vim paste from (and copy to) the system's clipboard?

I ran into this issue on a mid-2017 Macbook Pro running vim within iTerm2 as my primary development environment.

As other answers have suggested, I ran vim --version and noticed that it returns -clipboard, which means that the version of vim that shipped with my machine hasn't been compiled with the clipboard option.

The homebrew package for vim appears to compile with the clipboard option, so the fix for me was to:

1. Run brew install vim
2. Add set clipboard+=unnamed to my ~/.vimrc file
3. Close and reopen iTerm2
