Apple macOS High Sierra

Unless you're really into Photos or have installed the iOS 11 beta, there's no FOMO by passing on the public beta of Apple's latest OS.

Apple iOS 11

Siri will try to read your mind, and you can pay your friends back in a text. Plus, AR is gonna be huge.

Android O

Oreo doubles down on the nuts and bolts -- and speed.

Android Wear 2.0

With lots of new features, the LG Watch Sport and Style are the first to use the new software -- and it's promising.

Apple iOS 10

iOS 10 serves up plenty of useful quality of life improvements, but a few rough edges keep it from shining too brightly.

Apple MacOS Sierra

This free OS update for Macs launches a new era, tying Apple's computer OS more closely into iOS and WatchOS.

Google Android Nougat

Android Nougat offers welcome improvements in what is a functional, if not very exciting, update.

Mac OS X 10.11 El Capitan

If you own a Mac, you'll want El Capitan. This update simplifies the Mac experience, improving the tools you already use while promising improved performance to come.

Apple iOS 9

If you own a recent Apple device, you'll want to make the jump to iOS 9: Better battery life, improved native apps and multitasking prowess on the latest iPad make this upgrade a no-brainer.

Google Android 6.0 Marshmallow

Android 6.0 Marshmallow is out now. This is everything you need to know about Google's mobile operating system update.

Mac OS X 10.10 Yosemite

From new Continuity features to smaller, useful tweaks across core apps, Mac OS X Yosemite is a must download for Mac users.

Apple iOS 8.1

With the latest version of iOS and an NFC-equipped iPhone, you'll finally be able to pay for transactions with Apple Pay.

Google Android L

Google gives us a preview of the future of its mobile operating system.

Google Android TV

Google is taking yet another shot at a living room software platform with Android TV, which runs on the upcoming Android L platform.

Microsoft Windows 8.1 Update

With new functionality for the Start button and separate experiences for desktop and tablet users, the Windows 8.1 update finally gives people what they want.

Nokia X Software Platform

Nokia sure tried hard to give us something new, but its mashup of Android, Windows Phone, and Asha gives its Nokia X phone limited powers and a nagging identity crisis.

Mac OS X 10.9 Mavericks

As it's a free upgrade that gives you more apps, improved features across the board, and better performance, there is really no reason not to get Mavericks on your Mac.

Microsoft Windows 8.1

If you're a dedicated Windows 8 hater, the update to Windows 8.1 isn't going to change your mind. For everyone else, this collection of tweaks, fixes, and new features is useful, but everything here should have shipped in the original version last year.
