Why can't I upgrade to macOS High Sierra?

Episode 1477

Bob from Danville, CA
macOS High Sierra on MacBook Pro

Bob has a 2011 MacBook Pro with an SSD. Now he's trying to upgrade to macOS High Sierra and he's having issues. Leo says that it's looking for the original drive, and since Bob installed it as a secondary drive, it keeps looking to install on the first drive. The simple solution is to swap his drives and put the SSD as the main drive, and the other drive as his second hard drive.

Dick DeBartolo

Coach seats on an airplane are uncomfortable enough, but having to fight over the small armrest between coach seats makes it even worse. There's a neat solution for that. Soarigami doubles the existing armrest space and provides a friendly barrier, so you and your seatmate can comfortably share fairly. However, the company strongly suggests that before using the device, you simply ask your seat-mate neighbor if they're willing to share. Dick guesses that when you show them the Soarigami, they'll be very interested in sharing it.

Why is my laptop screen blank?

Episode 1477

Sam from South Williamsport, PA
Keyboard

Sam was printing up his son's graduating announcements and his cat walked across the keyboard and now the computer is blank. What happened? Leo says that there is a button on the keyboard that can turn off the screen. It's probably one of the function keys that was triggered to make the laptop look for an external screen. From the chatroom - here's an article on the subject. He can also program those buttons, so it may be a good idea to disable it.

How can I use my Apple lightning headphones with a regular headphone jack?

Episode 1477

Steve from Birmingham, AL
Apple EarPods

Steve wants to use his lightning headphones into a regular headphone jack. Leo says he probably won't be able to do that since the Lightning connector is proprietary. Those Lightning headphones are for one thing only — for use with the iPhone. Walmart does sell a female-to-male Lightning adapter, and there's one that actually comes with the Apple Pencil as well. Leo's not sure that this would actually work, though. It may be easier to just buy a cheap pair of earbuds that would have the proper connector.

Is it safe to plug my dash cam into my car's diagnostic port?

Episode 1477

Johnny from Atlanta, GA
Owl Dashcam

Johnny bought the Owl Dashcam and needs a few tips. Leo says that the Owl ties into its own LTE connection and communicates to you through your mobile device. It's also voice controlled and can save video clips with a simple command. Johnny is concerned that connecting the Owl to his onboard diagnostic port will void his Audi's warranty. Leo says that connecting to the OBD2 port could give someone access to the car's computer system, but the Owl only draws power from it.

Can I get rid of the RAID feature in my bios?

Episode 1476

John from West Palm Beach, FL
BIOS

John bought an SSD from Intel a few years ago, and it installed a RAID program in the BIOS of his computer. Now he can't get rid of it. What can he do? Leo says he should just ignore it. Most modern BIOS / EFI support RAID, but it doesn't really take up any usable room. It's just a firmware feature, so he can ignore it. He shouldn't mess with his BIOS anyway.

How can I securely erase an SSD?

Episode 1476

David from Hollywood, CA
Hard drives

Dan's computer was damaged and Acer is going to replace it, but he's worried about the data on it. How can he wipe the data? Leo says that there's a program called DBAN - Darik's Boot and Nuke that can wipe the drive pretty thoroughly. But Dan should understand that an SSD doesn't format the way a spinning hard drive does, and there can and will be some data leak, where someone could grab the data if they're really motivated.
