Can’t get your Mac to boot, even into macOS Recovery mode? Whether you’re replacing the hard drive or have a corrupt recovery partition, sometimes Apple’s repair tools won’t boot, which makes it hard to install a fresh copy of macOS or access other utilities.

You used to love Reddit, but it’s just not fun anymore. The jokes aren’t funny, the tips aren’t useful, and everyone is constantly fighting about internal drama or identity politics.

The touch bar on Apple’s new MacBook Pro makes sense. The top row of keys have served specific functions on Macs for over a decade; why not let those specific functions change depending on which application you’re using?

Switch to a new operating system and there are all sorts of little difference to get used to. The way macOS sorts folders and files is one of those things for migrating Windows users.

Press the “up” arrow in the Mac or Linux command line and you’ll see the last command you ran. Keep pressing “up” and you’ll see more commands; you can go back days, months, or even years.

Does someone you follow on Twitter retweet constantly, flooding your timeline with nonsense? Do particular accounts you never want to hear from keep popping up anyway? Here’s how to quickly filter that stuff out, without unfollowing people you otherwise like.

You closed the only Safari window that’s open, but on the dock you see the browser is still running. Are you going nuts?

When you close the lid of your MacBook, it goes to sleep. There’s no system setting you can tweak, and no command you can run, to change this. But there is a major exception to this rule, and another third party program that gives you control.

You’ve seen it. Maybe it was on an airplane, maybe it was at a friend’s house, but you saw people playing old Nintendo, Sega, or even PlayStation games on their computers. And yet, when you searched for those particular games in Steam, nothing comes up. What is this witchcraft?

Why spend $300 on an AirPort Time Capsule when you can make one yourself with a Raspberry Pi and an external hard drive? It takes a little tweaking, but once it’s all set up, your Mac will back up automatically, without any effort on your part. No more having to plug a drive into your computer.

Can hackers really record your webcam during “private” moments, then blackmail you with the footage? This idea, from the latest season of Black Mirror, is downright nightmare inducing. It’s no wonder Mark Zuckerberg and FBI director James Comey both put tape over their webcams.

At this point, you probably think you know all about the new features in macOS Sierra. So did I, but it turns out there are a few new things that didn’t get much press–especially when it comes to managing all your windows.

App Nap, added to macOS back in 2013, is not a feature that made headlines. So there’s no shame in admitting, three years later, that you still have no idea what it does.

Ever wish you could send YouTube and other web videos from your phone or laptop to your TV? It’s a trick you’ve probably seen Chromecast and Apple TV users pull, but don’t feel left out: you can get it working in Kodi too.

Let’s say you start a big download, then go to bed. When you wake up, you realize your Mac went to sleep before finishing its job. Isn’t there some way to stop this?

Wonder which of your Mac apps are connecting to the Internet, and what they’re doing? Private Eye lets you spy on your applications, watching every outgoing and incoming request in real time. And it’s free.

Apple’s macOS simultaneously offers the world’s most streamlined default browser, and the world’s most bloated default music player. And one has a bad habit of constantly launching the other. If you’re tired of Safari automatically launching iTunes, here’s how to stop it.

Once upon a time, there was a dumb person named Justin, who installed Java even though it’s awful. Even worse, this fool clicked “Next” without disabling the bundled offers.

When you’re binge watching a show, you don’t want to pick up the remote. You want the goodness to just keep coming while you lie there like a blob. Here’s how to set up Kodi to play the next episode of a show when the current one finishes–just like Netflix does.

You can use your Mac’s Terminal to download files, test your internet speed, convert images, or even listen to Pandora. All this and more is just a couple of Homebrew installations away.

Ever wish you could use tabs in your favorite apps? Thanks to macOS Sierra, you can. If you can open multiple windows with an app, there’s a good chance you can combine them into one, just like you do with your browser.

macOS Sierra’s picture in picture mode doesn’t natively support Netflix and YouTube, but a Safari extension adds a dedicated button for the job, letting you pop out videos for these sites with just one click.

Are websites telling you to install Flash in Safari, even though you’ve already installed it? Here’s what’s going on, and how to get those sites working again.

Homebrew makes it easy for Mac users to install command line tools, so it’s only logical that it runs entirely from the command line. But that doesn’t mean having access to a graphical user interface isn’t handy from time to time. Cakebrew is a free Homebirew GUI that makes overseeing your setup just a bit easier.

Wouldn’t it be cool if you could scroll up on any dock icon to quickly see all its windows, along with recent documents? A single command adds this otherwise hidden feature to your dock.
