These bogus Tech Support alerts are shown in such a way as to trick the user into thinking their computer has crashed or that a virus has been detected on the computer. It does this to try and scare the infected user into calling one of the listed numbers in order to receive support. In reality, though, they will only be greeted with people who are trying to sell them unneeded support contracts and services.
On the 11" Air, the left side of the computer has a MagSafe power connector, a USB port, a headphone jack, and a microphone.[12] The right side of the computer has a USB port and a Mini DisplayPort, now sharing Thunderbolt function beginning with the 2011 model. On top of the screen bezel there is a webcam, first dubbed iSight and now the FaceTime camera.
Marin Mac Tech used to offer efficient reliable service, but the last few times I've used his service, he has seemed much more interested in padding his bill and selling me unnecessary expensive gear.  This most recent experience was the worst.  Took in my NAS, ran up a large bill running diagnostic tests, told me it was the power supply, I ordered a new power supply, tells me it's still broken and now I should buy a very expensive one from him.  Ridiculous.  Not sure what happened to cause this slide.
On June 11, 2012, Apple released an updated model in the same form factor as the prior model. The new model is powered by the new Ivy Bridge dual-core Intel Core i5 and i7 processors, doubles the RAM and SSD speeds, has the new USB 3 ports (with USB 2 capability) in place of the USB 2 ports and the new MagSafe 2 charging port.[38] The camera was upgraded to 720p FaceTime HD.
Steve Jobs introduced the first MacBook Air during a speech at his keynote at the 2008 Macworld conference held on January 15, 2008.[6] The first-generation MacBook Air was a 13.3"-only model, initially promoted as the world's thinnest notebook[7] (1.94cm MacBook may be compared with 1.98cm for a previous record model, 2005's Toshiba Portege R200[8]). It featured a custom[9] Intel Merom CPU and Intel GMA graphics. In late 2008, the CPU was updated to a faster, non-custom Penryn CPU and integrated Nvidia GeForce graphics while the hard drive capacity was increased and the micro-DVI video port was replaced by the Mini DisplayPort.[10] A mid-2009 refresh, introduced alongside the MacBook Pro family, featured a slightly higher-capacity battery, and a faster Penryn CPU.[11]

Nov 5 Video Freezes When Tabbed Out Yesterday I "upgraded" to Mojave. While I am playing the game, if I tab out for any reason--be it with the 4-finger swipe to another tab, or any of the launch-type buttons--the game video stops working in the background, and the Beach Ball spins. The audio continues to work, and it seems like the game continues to play, as I often tab out between flight paths, and when i reboot the game, I am at the destination flight path. 15" Late-2014 Retina MBP 10.14 Mojave 2.5 GHz Intel Core i7 16 GB 1600 MHz DDR3 NVIDIA GeForce GT 750M 2048 MB 512GB SSD EDIT: Playing in Windowed Fullscreen Mode.Moleqular24 Nov 5
Oct 30 Discreet or Integrated GPU I have a late 2012 iMac with a NVIDIA GeForce GT 640M 512 MB. WoW has worked great on this machine since I bought it in 2013 for $1030 with no tax (on a military post). Since BfA install/launch, it has slowed down considerably, and not just with the game. It has slowed down period. I thought about adding more RAM (I have 8GB), hearing that iMacs with integrated graphics share memory with the graphics. I looked into it and couldn't figure out how to tell if it had integrated graphics... the instructions I found specified to "look at the About This Mac settings." Well, all I see is the NVIDIA, but nothing indicating discreet or integrated... so after searching deeper, it "appears" that this is not integrated. Is this a proper assumption? Anyway, I really don't want to buy a new machine, but I may have to. I did find this on Craigslist, but I'm not sure if I want to bite. Oct 30

Every Mac comes with one year of hardware repair coverage through its limited warranty and up to 90 days of complimentary support. AppleCare+ for Mac extends your coverage to three years from your AppleCare+ purchase date and adds up to two incidents of accidental damage coverage, each subject to a service fee of $99 for screen damage or external enclosure damage, or $299 for other damage, plus applicable tax.1 In addition, you’ll get 24/7 priority access to Apple experts by chat or phone.2
Still, to buy AppleCare+ after the fact you generally have to run a diagnostic test on the device in question, so Apple knows it’s in good working order. And no matter when you buy your AppleCare+ plan, the coverage starts from the day you bought your device. So you don’t get an “extra” two months of coverage if you wait two months to buy the plan.

Starting over again, multiple times, I kept getting the same result, until (without any real indicator of why) everything worked properly. The words "phone number" finally appeared above that field, and the form also automatically formatted my number in the (123) 456-7890 style and allowed me to receive the calls. This error came up during my first two calls, but not my third.
