Should I update my old Mac?

Dave from San Diego, CA

Episode 1255

Dave has an old iMac that works fine, but when he gets on some websites, it starts to lag. He could update to OS X El Capitan, but would that help? Leo says that its a good idea to update for security reasons, but it probably won't help when loading up certain websites. It really depends on the site. What's more likely is that the hard drive is slowing him down. A bad sector can really slow it down as the computer is trying to read it. Leo advises backing up his data, format the hard drive and then update to El Capitan. Dave should download El Capitan first and put it on a USB Key.

Why don't Macs have a delete key?

Episode 1255

John from Santa Cruz, CA
Apple Keyboard

John uses Windows, but he has an iPhone 6. The one thing he doesn't get is why Apple computers don't have a delete key. Leo says that Apple wants to get rid of older keys from the early days of computing, including Print Screen, Pause/Break, and even the Delete key. Apple actually got rid of the Delete key a long time ago. John will have to press CMD/Backspace to duplicate that function.

Why are my icons pixelated on my MacBook with Retina display?

Episode 1255

Danny from Los Angeles, CA
Apple MacBook Pro

Danny is having issues running Adobe Photoshop Elements 10 on his MacBook with Retina display. The icons look pixelated. Leo says that is a common issue with the Retina display when using an older version of an app. Apple deliberately makes the display larger and at half the resolution so he can see what he's looking at. He'll get the full resolution for videos and images, however.

Is it harmful to use an external battery with my iPhone?

Episode 1254

Kenny from Temple, TX
Apple iPhone Battery Case

Leo says it isn't harmful at all, and Apple even sells an external battery for the iPhone 6/6s. In general with these charging cases, when you charge the case it will also charge the phone. On the Mophie cases, there's a switch for when you want to switch to the battery. When it comes to Lithium Ion batteries, though, the best thing to do is keep it charging. The battery will last longer if it stays charged vs charging and discharging. It's definitely not good to let it fully drain.
