All the ways you can start up your Mac

We’ve talked quite a lot about Recovery OS, an underestimated feature of OS X that makes it easier to troubleshoot your Mac even if it refuses to start up properly.

But as you’ll see for yourself in this post, Recovery OS is but one of the more than dozen different ways to start up your computer, aside from OS X’s regular startup mode. In this tutorial, we’ll list all the ways you can start up your Mac and detail each one.

Most of the time, your Mac just works—until it refuses to start up properly due to an unforeseen system error, a misbehaving app, a broken system component and what not. Beyond system errors, different people have different needs when it comes to starting up their computer.

For example, you could be a pro user who dual boots between OS X and Windows on a daily basis. Others might be wondering about booting a Mac from a disk other than their designated startup disk. Or perhaps you’re looking to isolate the cause of a software issue in OS X’s Safe Mode or boot straight into Recovery OS as the last option?

For those of you who have wondered about the many ways you can start up your Mac, here’s a quick list of the keyboard shortcuts you can invoke to access handy OS X features which are only available at boot time.

Enter macOS Verbose Mode.

Not only does Verbose Mode makes it easy to access detailed status messages as your Mac is starting up, but also lets you see what’s really going on behind the scenes and watch as macOS loads kernel extensions and other startup items.

In this tutorial, we’re going to cover booting your Mac in macOS’ Verbose Mode, explain in which situations it might come in handy and give you some handy tips related to using Verbose Mode.
