Do you use Apple’s Messages to send code snippets to text to other developers, or to yourself, BUT messages converts your ” and ‘ to smart quotes and when you then copy that code and … it doesn’t work?
That’s annoying!
The Fix:
Open Terminal or iTerm on your Mac and paste in the following command:
defaults write com.apple.messageshelper.MessageController SOInputLineSettings -dict-add "automaticQuoteSubstitutionEnabled" -bool false
This is one command, it may be wrapped or span more than one line, but it is only one line/command.
