Whenever I fly, I always end up dialling the brightness down on my laptop to its lowest possible setting. In some cases, I'm straining my eyes to be able to see what's on the screen, but it's worth it for the precious few extra minutes of battery life I might get while I'm in the air and away from power.

You really have no reason to think about air quality unless there’s a problem. And when there’s a problem, there’s a problem. I live in Northern California, and the tragic Camp Fire has created incredibly unpleasant — if not unsafe — conditions throughout the area.

If you're the kind of Mac user who never likes taking their hands off of the keyboard, an app launcher utility like Alfred can be your best friend.

If you don’t have a dual-monitor setup or an ultra-wide display, your options for multitasking on your PC are limited. It’s going to be trickier to put on a YouTube video while you work, since anything you’re doing in your primary window — Excel, let’s say — is going to sit on top of what you’re trying to watch. And running the two windows side by side isn’t going to look very good, either.

Everyone loves a good app bundle, and BundleHunt> — creators of just that, for your Mac — has launched its brand-new holiday bundle of apps. Get stoked, because you have a grand total of 46 heavily discounted apps to pick from.

I was recently tasked with setting up a Windows 10 system for a friend on an oldish laptop. While the machine is about five years old, it does have an SSD and ran Windows 7 and 8 pretty well. So, I needed to create installation media for the system. But, as my main system is a Mac I needed to find a way to create a bootable USB or SD Card. Here's how I did it.

Mac: I quit a lot of conversational podcasts early. They get boring for a few minutes, I try hunting for the next good bit with 30-second skips, and I give up and delete the episode.

Picture-in-picture (PIP) video playback is a user-favourite feature on Android’s Chrome app, and you can now get it on your Chrome desktop browser — as long as you’ve updated to Chrome 70, that is.

In a recent blog post titled "Hardening macOS," Ricard Bejarano offers an extensive list of settings you can tweak to make macOS as secure as possible. It's a comprehensive list of tasks — and we love it — but it's important that you understand the "why" behind his recommendations, too. Here are a few of his top tips and explanations for why you're adjusting, installing, or modifying your Mac that way.

Dear Lifehacker, Three or four years ago, my Macbook died, and because I was an avid user of Time Machine, I was able to retrieve virtually everything I cared about from my external hard drive, except my photos. Because this tragedy happened to coincide with a software update, the updated photos couldn’t access the old photo library that was stored on the other drive.

New macOS versions usually mean better performance on Apple’s latest hardware, but they’re rarely optimised for anything older (even last year’s models). So what’s the consensus on macOS Mojave, Apple’s latest operating system, when it comes to older machines?

Apple has released the latest version of its personal computing operating system. macOS Mojave is the fifteenth major release of the OS that began the company's recovery through the second Steve Jobs-led era of the world's most valuable tech company. How do you get it? What's different and should you upgrade?

The latest and greatest version of macOS is here. Whether you’ve been bingeing on the beta for months or forgot all about version 10.14 of Apple’s desktop operating system, you can download the final version of macOS Mojave starting right now. Well, maybe.

The Lifehacker staff sifts through a ton of apps on a regular basis, but a few have stuck with us over the years. Some apps are simply nice to have, while others have become essential in our daily lives. From dealing with irate dragons to counting our mindfulness minutes, each app on this list has a special place in our hearts (and our homescreens). Best of all, they're completely free to download!

Apple launched the newest version of its Safari web browser, Safari 12, for macOS Sierra and High Sierra users on September 17, and it brings a bunch of new security features and handy little touches — including favicons.

There are plenty of reasons to run a virtual machine. The first, and most compelling, is that you want to play: Maybe there are some other operating system you want to dabble with (cough Linux cough), but you don’t want to deal with installing another hard drive, partitioning your existing drive, or setting up your system a different way.

It’s that time again: Time for your annual frantic search to find all of the original packaging for your older iPhone, iPad or Apple Watch. That’s the best way to sell it for the highest possible sum, after all, before you plunk down a preorder for whatever Apple’s announcing this week.

I’ve been recommending CleanMyMac to friends and family for a while now, and it gets better with every version. CleanMyMac X was released yesterday, with powerful new tools for optimising and protecting your Mac.

Mac: While most people set up their Macs so all they need is a password, or a finger-press, to authenticate into their machines, the computer your company gives you might be a little more strict. Instead of letting you save your login name or display a list of your system’s users to pick, for example, you might have to actually type in your account name and password.
