If you cannot switch from the unresponsive app, press Command + Option + Shift + Esc for three seconds to force it to quit. This key combination tells macOS to force quit the front-most app.Alternatively, if you are using Safari or any other browser, you can disconnect your Internet, then open the web browser, navigate from the malicious web page, then reconnect to the Internet.
For Macs, AppleCare+ makes more sense if you’re buying a laptop and you’re worried about the screen, or you just tend to be rough on your computers. Desktop Macs probably aren’t as important to cover, since the likelihood of, say, dropping one is a lot less. Still, Macs have a long life, so you may decide three years of (transferable) protection is worth the extra cost.
Through July 1, 2013, the MacBook Air took in 56 percent of all Ultrabook sales in the United States, despite being one of the higher-priced competitors. [66] Apple had previously dominated the premium PC market, in 2009 having a 91 percent market share for PCs priced at more than $1,000, according to NPD, and Ultrabooks were an attempt by other PC manufacturers to move in on Apple's turf.[67] While Apple's MacBook lines were not immune to this consumer trend towards mobile devices,[68] they still managed to ship 2.8 million MacBooks in Q2 2012 (the majority of which were the MacBook Air) compared to 500,000 total Ultrabooks,[69][70] despite there being dozens of Ultrabooks from various manufacturers on the market while Apple only offered 11" and 13" models of the Macbook Air.[71] Forrester Research analyst Frank Gillett attributes Apple's increased success in the enterprise market to the 2010 MacBook Air and the iPad.[72]
Programming articles, news, and how-to’s are a big piece of MacTech’s history. Applications developers will always be on the cutting edge of technology. These developers need the most reliable, most up to date, and most detailed information about new Apple technologies. They need to know what development tools are available, and how they measure up. MacTech will continue to provide those resources.
Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
More than that, Travis took my list of "fix its" and walked through my small business info/tech from a management perspective.  He quickly, systematically optimized my systems, step-by-step -- and now my online scheduling, calendaring, contact management, backups, data storage are all simplified and running better.  Travis also suggested steps we can take in the future to get my technology running more simply and efficiently, too.  He offered his guidance with a light touch - kind & with a sense of humor, too.

The 2010 models include two speakers for stereo sound while earlier versions have one speaker located under the keyboard.

The 2012 model replaces USB 2 with USB 3, and uses the MagSafe 2 instead of the MagSafe connector for charging. The 2015 model updated the Thunderbolt port to Thunderbolt 2.
On June 10, 2013, Apple released another update in the same form factor as the 2012 model during the company's Worldwide Developer Conference (WWDC). The 11" and 13" models have a minimum standard 4 GB RAM, with a maximum configuration of 8 GB. Both models are powered by the Haswell ULT 1.3 GHz dual-core Intel Core i5 processors, with Turbo Boost up to 2.6 GHz, while a 1.7 GHz Dual-Core i7, with Turbo Boost up to 3.3 GHz, option is also available. Each model's storage standard is 128 GB SSD, upgradeable to 256 GB and 512 GB SSD. Due to Haswell CPUs, battery life has considerably improved from the previous generation, and the mid-2013 models are capable of 9 hours on the 11" model and 12 hours on the 13" model; a team of reviewers exceeded expected battery life ratings during their test.[39]

Systems developers are finding the Apple technologies to be a powerful option for providing network solutions. From a single user, one operating system personal computer, OS X has expanded to serve just about every type of network content available and host multiple operating systems. Powerful system command and scripting languages like Perl and AppleScript allow administrators and users to provide system level solutions in a fraction of the time it would require to develop application level solutions.
MacBook Air components are officially non-user-replaceable, though third-parties do sell upgrade kits for the SSDs. The flash memory and battery are enclosed within the casing, with RAM soldered onto the motherboard. The flash memory, difficult to access, has a 128 MB cache[40] and a mSATA connection (updated to a proprietary PCIe interface) to the motherboard.[41]
Thanks for the article. However, if by "power of positivity" you mean condescending attitude, providing cookie cutter replies to one's questions for the sole purpose of diverting the issues, and overall being insincere and shifting the responsibility of the problem onto the consumer, well, yes, Apple is at the top of the list. The so called "Genius Bar" is useless and its geniusless techs feign ignorance of problems which are listed in the millions on a basic online search. As others have already pointed out, I have been a faithful Apple customer for many years, but the lack of "customer service" (ie: "resolving problems") leads me to say Apple no more.
