OS X is holding back the 2013 MacBook Air’s 802.11ac Wi-Fi speeds

Apple’s 2013 MacBook Air and new Airport Extreme Base Station are the company’s first 802.11ac products, and there are some bugs that need to be worked out. Apple Apple’s 2013 MacBook Air doesn’t look like much of an upgrade from the outside, but the story is different on the inside. We’ve spent the better part of a week using the new Air and measuring just how Intel’s new Haswell processors , the PCI Express-based SSD , and the 802.11ac Wi-Fi adapter change the laptop compared to last year’s model. The new Wi-Fi chip was the change that I was the most eager to get my hands on. I’m always looking to boost my network speeds, but I’ve been waiting for hardware based on the new 802.11ac standard to become more widely available before upgrading everything on my network. Reviewing both the new Air and Apple’s new 802.11ac-capable Airport Express Base Station simultaneously would give me a chance to see just how close the lauded “Gigabit Wi-Fi” would come to fulfilling its promises. I was unpleasantly surprised by the results. Both the 2012 and 2013 MacBook Airs use four antennas to transmit data—two to send data and two to receive it. Each set of antennas can theoretically send and receive 150Mbps (or 18.75MBps) using 5GHz 802.11n for a total of 300Mbps (37.5MBps). Under 802.11ac, the size of each stream is increased to 433Mbps, making for a maximum theoretical link speed of 866Mbps (108.25MBps) in the 2013 MacBook Air. Actual network transfer speeds rarely (if ever) come within spitting distance of these theoretical maximums, but we would at least expect the actual 802.11ac transfer speeds to increase by a similar percentage compared to 802.11n.

Apple announces flatter, sleeker iOS 7

A new version of Apple’s mobile operating system, iOS 7, was announced at the company’s Worldwide Developer Conference (WWDC) at the Moscone Center in San Francisco. The release will feature, among a number of changes, a departure from the bubbly, skeuomorphic design that has prevailed on both iOS and OS X for the last several years in favor of flatter, more angular design elements influenced by Apple SVP of Industrial Design Jony Ive. The most front-facing part of the OS, the home screen, now has app icons that lack the dimension and gloss effect of previous versions. Design elements within the icon, like the musical note on the Music app icon, appear as a flat design flush with the background rather than a cutout like before. iOS 7 isn’t doing away completely with dimensionality, as some text elements shown in the intro video still feature embossing, and Ive emphasized that the OS focuses on “depth and vitality.” The look of several key apps in iOS 7. Many of the skeuomorphic touches are also gone from the OS, such as the textured paper in the iBooks app and the leather-bound elements in the Calendar app. Of the Game Center redesign, Apple SVP of Software Engineering Craig Federighi stated, “we just ran out of green felt.” Read 14 remaining paragraphs | Comments

Apple unveils OS X 10.9, “Mavericks”

Apple today unveiled OS X 10.9 at its Worldwide Developers Conference (WWDC), showing off the first major revision of the Mac’s operating system since last year’s Mountain Lion . Apple has apparently run out of cat names and is now naming releases after places in California, where OS X is developed. The new OS X is thus named ” Mavericks .” Developers are being given a preview version of Mavericks today. It will be available to the general public in the fall. New features include tabs in the Finder, allowing multiple Finder windows to be drawn together in tabs. Apple is bringing tagging to documents—any tags you add to a document will appear in the Finder sidebar and in iCloud. Multiple tags can be added to each document, and these tags will allow new search capabilities. Mavericks will make life easier for users who have multiple monitors. Menus will be spread across the different displays, and users will be able to take a window full-screen on one display without disturbing the desktop on another display. HDTVs connected to Apple TV boxes can also act as displays. Mission Control has been “super charged for multiple displays,” Apple said, making it easier to drag apps and windows from one monitor to another. Read 12 remaining paragraphs | Comments

Mac malware that infected Facebook bypassed OS X Gatekeeper protection

Researchers have identified the Mac malware that infected employees of Apple, Facebook, and Twitter, and say it may have been used to compromise machines in other US organizations, including auto manufacturers, government agencies, and a leading candy maker, according to a published report. Pintsized.A is a new family of Mac malware that uses an exploit to bypass Gatekeeper, an OS X protection that allows end users to tightly control which sources are permitted to install apps , according to an article published Monday by The Security Ledger. Mac antivirus provider Intego says the trojan masquerades on infected machines as Linux printing software known as cupsd, although it runs from a different location than the legitimate title. It’s unclear exactly how the malware gets around Gatekeeper. Once installed, Pintsized establishes a reverse shell to a command and control server controlled by the attackers. It uses a modified version of the OpenSSH utility to encrypt traffic, a measure that can help it remain undetected on infected networks. One of the domain names that hosted such a server was corp-aapl.com. It caught the attention of members of Facebook’s security team, tipping them off that there was an infected machine inside their network . When they later took control of the domain, they discovered multiple other companies were also compromised by the same attackers. Around the same time, Apple , Twitter , and Microsoft were also hit with attacks that meet the same pattern. Read 1 remaining paragraphs | Comments

New features, new fixes: OS X Server’s six-month checkup

It has now been roughly half a year since the release of Mountain Lion . If Apple sticks to its new yearly release cadence for new OS X versions, that means we’re probably about halfway to OS X 10.9. That doesn’t mean the OS has stood still, though—two point updates have since tweaked the operating system’s functionality and stability, and this is even more true of OS X’s buttoned-up cousin, OS X Server . While Windows Server rarely picks up major new features outside of service packs, OS X Server is like the client version of OS X in that it sometimes takes a couple of point updates for its features to stabilize. Since July, we’ve received two point updates for OS X Server, and they’ve changed things around enough that it merits revisiting our original guide and pointing out what has changed. We’ll be focusing on the major user-facing changes here, but for a complete list of everything that has been changed and fixed you may also want to look at the complete release notes for OS X Server 2.1.1 and 2.2 .

New Mac trojan tricks users into paying pricey cell phone fees

Doctor Web Researchers have discovered new Mac-based malware that’s designed to trick users into paying pricey subscription fees. Dubbed Trojan.SMSSend.3666, the trojan masquerades as “VKMusic 4 for Mac,” a name that closely resembles an app used to listen to music on a popular Russian social networking site, according to a report published on Wednesday by Russia-based antivirus provider Doctor Web. An installer prompts users for a cell phone number, purportedly as part of the registration process. Users who respond to a subsequent text message then receive a bill charged to their mobile account. “Trojans of this family used to plague Windows users, but Trojan.SMSSend.3666 targets owners of Apple computers,” Wednesday’s advisory stated.

Fully loaded new 27-inch iMac will cost over $4,200—before tax

Apple’s newer, thinner iMacs are due to be released tomorrow , with the 21-inch models showing up in stores and shipping immediately, and 27-inch models shipping some time in December. While base model pricing and configuration options have been known ever since the new models were announced in October, Apple has not yet officially announced the pricing of any of the add-on options like video cards and extra storage, so potential purchasers haven’t yet been able to nail down their total pocketbook impact. Enlarge / Base pricing for the new iMacs. Image from store.apple.com However, earlier this week MacRumors posted news from an Apple reseller named Expercom , which reportedly contains the entire set of iMac build-to-order upgrade prices. According to that list, a fully loaded 27-inch iMac will cost an eye-watering $4,249, before tax: Base price, 27-inch iMac, 3.2GHz quad-core Intel Core i5, NVIDIA GeForce GTX 675MX video card, 1TB HDD, 8GB RAM: $1,999 Upgrade to 3.5GHz Intel Core i7: $200 Upgrade to NVIDIA GeForce GTX 680MX video card: $150 Upgrade to 768GB SSD: $1,300 Upgrade to 32GB of RAM: $600 Tossing in 6 percent for a guess at sales tax (obviously, this varies by state and even city) yields a grand total of $4,503.94 for an iMac with every single upgrade box checked. Hope you brought a second pair of underwear… preferably one stuffed with $100 bills. Read 5 remaining paragraphs | Comments
