Get More Out of Live Photos on iPhone

If you have an iPhone, you may already be familiar with the Live Photo feature that it has. When Live Photos are enabled, whenever you take a picture, the iPhone will also capture a few seconds before and after the shot is taken. This gives the photo some motion, almost like a very short video clip. But you may not know that it can actually go beyond just that basic functionality. After you take a photo of something that moves, go to edit the photo and swipe up. This will reveal a few different effects that you can apply.

Ebay lost money because it had to pay $3.1 billion, and Lenovo lost money because it had to pay $400 million in taxes.

Episode 1452

Processor

2018 brought about the news that every processor built in the last ten years have a flaw in them that could give hackers access to sensitive data. Initially believed to affect just Intel processors, the latest is that this affects every single processor made, regardless of platform.

The latest exploit "Spectre" affects every single chip made in the last ten years.

Leo says that Microsoft has already pushed out a fix, and Apple's High Sierra has patched the vulnerability with a recent fix. Apple has also patched the iPhone and iPad.

Apple Releases iMac Pro

Episode 1448

Apple iMac Pro

Apple has released the iMac Pro, which it announced earlier this year. This computer starts at $4,999, and it's not hard at all to configure it up to $10,000. This is for professionals who are using it for business, like 3D design, photography, and video editing. Even if you did decide to spend the money on that, it still wouldn't be the fastest computer out there. This isn't even the fastest Mac. It all depends on what you do. It's using the Intel Xeon chip, which has 8, 10, 12, and 16 cores. But, when you get these multiprocessor Xeon chips, they run at a slower clock speed per process.

Why doesn't T-Mobile insure the iPhone X?

Episode 1448

Mike from Tinley Park, IL
Apple iPhone X

Mike got an iPhone X on T-Mobile from the Apple Store. He took it to T-Mobile to activate it, but found out that T-Mobile won't insure it. Leo says that's because Mike bought it from Apple, not T-Mobile. So Apple Care applies. Leo tends to self-insure because extended warranties are profit centers for the seller. But the iPhone X is very expensive to repair or replace. So he does make an exception with Apple Care, but he'll want to get Apple Care Plus. If he breaks it once, it's probably going to pay for itself.

Should I buy a refurbished MacBook Pro?

Episode 1446

Eric from Long Beach, CA
MacBook Pro

Eric is looking to get a Best Buy refurbished 2011 MacBook Pro for $600. Is that a good deal? Leo says he usually recommends getting a refurb model from the manufacturer. He'll get a warranty that way. Best Buy probably wiped the hard drive and checked a few things, but it's not strictly refurbished. 4GB RAM is also a little light, but it will support High Sierra MacOS. Warranty wise, a good refurb should include a 1-year warranty. 3 months won't really help him. Leo would also recommend spending a little more money and getting a 2015 model.
