Dennis is using GarageBand on the iPad and wants to know how he can use an external microphone and turn off the iPad's mic. The problem is how Dennis is connecting. Leo says to use a USB microphone like the Shure Motiv. The Microphone will be seen by the iPad and get used instead of the onboard mic.
Alex wants to upgrade his Mac and attach it to a MIDI keyboard to make music. He wants to be able to tether it, not rely on a network or wifi connection. Leo says that macOS doesn't support touch, so he'd have to use a simulated mouse. But it's doable. Leo would recommend going with a Thunderbolt connection in order to do it. The chatroom says that there's a Mac Compatible touchscreen Monitor on sale at Amazon.
Joe has a USB touch monitor. How can he plug it into a power adapter to go over 15" away from his computer? Leo says that the biggest challenge may be the length of your cable. Monoprice sells one that's 32' long and has a dongle on it that amplifies the signal. You'll also need a USB hub that can get you the power, but you may lose too much signal to get the data.
Robert is annoyed with modern web design. It's so hard to read. Leo says that web design is done by 20/30-year-olds these days, and black text on a white background has grown out of fashion. But you can press CMD-SHIFT and + or - to make the text larger. And it will remember. All browsers also allow you to apply a set format to a modern webpage. It's called Custom CSS. Check your browser settings.
Jeff has an online radio network that he runs on a series of Mac Minis. But he found a bug in the audio that's causing a whine. Leo says that it's likely from the digital-analog converter (DAC) chip that has failed. He recommends getting a USB DAC, rather than just paying to repair it. The quality audio will be better. But if he has Apple Care Plus, Apple will just replace the logic board.
John calls in to talk about how you can get a USB to PS2 adapter for your old keyboard and computer if yours doesn't have a USB port. Leo says that if you are still using a computer that doesn't support USB keyboards, this is a good way to do so. However most, if not all, computers support USB in some form and way.
Scott's USB lightning cable has stopped working in his car. Says there's no music available on the car screen. Leo says to try a new cable to eliminate the possibility that the cable is going bad. Also, there may have been an update to CarPlay that isn't supported by the car stereo head unit. Apple may have changed something in a recent iOS update. Another option is to turn the phone off completely and then turn it back on. That'll reset the network settings. Check the stereo's website under "support" to see if there's any technote on the issue.
Tom got a notice from Microsoft to update Windows 10, but now it won't recognize his keyboard, so he can't log in. Leo says that Tom can eliminate the keyboard as the problem by trying it with another computer. But likely, the update deleted or corrupted the USB drivers. Log into safe mode and see if it works. If you can at least get into the BIOS setup, then you know it isn't the keyboard.
Bernie ordered a Blackmagic ATEM Mini to learn how to do video streaming and switching. But he hasn't gotten it yet. Leo says that it works great as an affordable streaming device. But he has a problem with connecting his webcams because it requires HDMI in. Leo says that he uses DSLRs because they offer clean live HDMI out. Is there an affordable USB to HDMI adapter?
Stacy's hard drive is filling up after scanning a ton of photos. Her computer only has two USB ports. Does she need a hub in order to connect a USB thumb drive with an external hard drive? Leo says no. She should be able to plug them both in, and then drag from one to the other. But remember, if she deletes those images off the thumb drive, she still only has one copy. She should have three. Use Google Photos to upload them. Flickr gives 1000 photos for free. Shutterfly is free. And if she is an Amazon Prime user, she gets free photo backup as well.
