How to Perform a Clean Installation of macOS Sierra

macOS Sierra is Apple's latest desktop operating system, which succeeds OS X El Capitan and adopts a new name to bring it in line with iOS, watchOS, and tvOS. The OS will come pre-installed on all new Macs once current stock is depleted and is a free download for existing Mac owners. The main new feature in macOS Sierra is deep Siri integration, bringing Apple's personal assistant to the Mac for the first time. It also adds new features to Photos and Messages, and includes Continuity smarts like Universal Clipboard and an Auto Unlock option for Apple Watch owners. This tutorial explains how to download macOS Sierra and perform a clean install, which offers several benefits over the automatic upgrade process included in the installation package.

Researchers Uncover macOS and Safari Exploits at Pwn2Own 2017

The seventeenth annual CanSecWest security conference is underway in downtown Vancouver, British Columbia, where researchers are competing in the 10th anniversary Pwn2Own computer hacking contest for over $1 million in prizes. Day one results have already been published over at the Zero Day Initiative website, with a couple of successful Mac-related exploits already appearing in the list of achievements. Independent hackers Samuel Groß and Niklas Baumstark landed a partial success and earned $28,000 after targeting Safari with an escalation to root on macOS, which allowed them to scroll a message on a MacBook Pro Touch Bar. In a partial win, Samuel Groß (@5aelo) and Niklas Baumstark (@_niklasb) earn some style points by leaving a special message on the touch bar of the Mac. They used a use-after-free (UAF) in Safari combined with three logic bugs and a null pointer dereference to exploit Safari and elevate to root in macOS. They still managed to earn $28,000 USD and 9 Master of Pwn points.Later in the day, Chaitin Security Research Lab also targeted Safari with an escalation to root on macOS, finding success using a total of six bugs in their exploit chain, including "an info disclosure in Safari, four type confusion bugs in the browser, and a UAF in WindowServer". The combined efforts earned the team $35,000. The participating teams earned a total of $233,000 in prizes on day one, including a leading $105,000 earned by Tencent Security, according to published details. Other software successfully targeted by contestants include Adobe Reader, Ubuntu Desktop,

Apple Refers to OS X as 'MacOS' in Environmental Webpage Update

With the launch of the Apple Watch and the fourth-generation Apple TV, Apple debuted two new operating systems -- watchOS and tvOS -- both of which share a common naming scheme with iOS, the operating system that runs on iPhones and iPads. Apple's unified naming system has led to speculation that OS X, the operating system for the Mac, is due for a name change to MacOS, bringing it in line with watchOS, tvOS, and iOS. Apple won't unveil the name of the next-generation Mac operating system until its 2016 Worldwide Developers Conference, but a new update to the company's website suggests MacOS is on the minds of Apple employees and a candidate for the name of the next upgrade. On a webpage that was updated this morning to share Apple's most recent environmental report, a Frequently Asked Questions section makes a mention of "MacOS." When discussing power consumption of products, MacOS is listed alongside tvOS, iOS, and watchOS.To model customer use, we measure the power consumed by a product while it is running in a simulated scenario. Daily usage patterns are specific to each product and are a mixture of actual and modeled customer use data. Years of use, which are based on first owners, are assumed to be four years for MacOS and tvOS devices and three years for iOS and watchOS devices.A mention of "MacOS" was also found buried Library files in OS X 10.11.4 in late March, but the file, "FUFlightViewController_macOS.nib," has been present in the Mac operating system since August of 2015, a month before the public launch of OS X El Capitan. If Apple does make the

Rumors of Coming 'macOS' Rebrand for OS X Refuse to Die

The discovery of a change in file naming conventions in OS X 10.11.4 is behind a recent growth in speculation that Apple is set to rebrand its OS X desktop operating system. Screenshot from Mac OS 8 released in 1997. The rumor appears to have begun on Tuesday after Brazilian Apple blog MacMagazine reported that a name used for an Interface Builder document tucked away in the OS X System folder contained a previously unseen reference to 'macOS'. Developer Guilherme Rambo discovered that a document in FlightUtilities.framework in /System/Library/PrivateFrameworks takes the name FUFlightViewController_macOS.nib, which it did not have prior to last week's release of OS X 10.11.4. Image: Guilherme Rambo Speculation appears to be based on the fact that iOS, watchOS, and tvOS already take similar naming conventions, leading some to believe that OS X could be set to fall in line. However, as 9to5Mac points out, there are good reasons to remain skeptical that the change indicates an imminent rebrand. Apple developers often use macOS identifiers for convenience, because the naming scheme suffix shares symmetry with Apple's other platforms and allows coders to easily identify apps with cross-platform components. Additionally, a significant rebrand of Apple's flagship desktop OS is the type of marketing decision that engineering teams would be unlikely to hear about until later on in the version cycle. Despite the skepticism, a rebrand for OS X is by no means out of the question. Indeed, the name change would see Apple revert to the operating system's traditional
