You can browse Console's log archives, but it is an arduous process that involves creating a system diagnostic report first. That means, if your Mac crashed and you want to find out why, opening console after the fact may not yield you any useful information. Unfortunately, Console has also been redesigned to only show you data from the time you open the app. Or, you can save it to your Notes or Reminders app, or another third-party note-saving app. You can also share that information to someone else via email, text, and social media. When you select a line, something that is causing an error or fault, for example, you can view additional detailed information about the problem.
