Apps, Operating Systems (Windows, MacOS, Linux), or pro level software.
Mark wants to know if he can check out Linux on his iMac. Leo says in theory, yes. But Leo's experience is that they don't really work hand in hand well. Do some research online to see which version of Linux works best on a Mac. Then put that version on a USB key, then boot the mac holding down the command key. That'll give you a list of drives to access, and then you can run Linux on the USB key to see if it works.
Stan is having a computer display issue. He has issues when he plays video. But when he uses Linux remotely, he has no issue. But when he's on Linux directly, he has an issue. Leo suspects that there's an issue with the video card. Maybe an incompatible video driver. You could remove the driver, and reinstall it. Or, get an inexpensive video card and see if it fixes the problem. Leo says that using a different flavor of Linux, like PopOS could also solve it.
Clinton is looking for an app to manage customer interaction. Leo says that's called Customer Relationship Management (CRM). The king of CRM is called SalesForce. Its what everyone really uses, but it may be overkill for a small business. There was another one called ACT from back in the day. But that is long gone.
Gold Mine is a small business CRM that starts with your contact list and then expands it. Another is SUGAR. Monday is an advertiser and it works well for small businesses. ZoHo. Look at Capterra. That's a good place to start.
Michael is wondering about the minimum requirements for a computer to watch streaming TV online. You don't need to worry about that as much Leo says as most computers can do it easily. If the Roku or Amazon Fire TV USB sticks can do it on a small device, then almost all computers or laptops now and days can stream online video content.
Diana is having issues with her iPhone 6S+ camera after the Apple Store updated her phone to the latest supported software, has had notifications popping up more frequently, and wants to fix it to continue using it. Leo says you can uninstall the apps on your phone to clear up space & anything that would be bogging down the use of your camera. You can also disable notification popups within your apps, but you will need to do it manually with each app.
Howard is having trouble with iMovie. He can't share video from it. It's constantly a compressor error. Leo says that iMovie has to render a video file using Apple Compressor. There may be a damaged file. There was an update this week, so check to see if that fixes it. If it doesn't, try uninstalling and reinstalling. Make sure to delete the compressor file and then reinstall it.
Mike wants to know if he can use more than one monitor on his computer. Leo says that most modern-day computers do support multiple monitors and both Windows and macOS support it natively. But the computer has to have more than one display port or HDMI port to do it. Most do out of the box these days.
George has an iMac, but it won't let him upgrade to Catalina. Leo says to go to the Apple Menu and look under System Preferences. There's an update feature there, so select the gear. It'll run the update check. He can also look for the compatibility checker here - https://www.apple.com/macos/catalina/.
Doug just got back from vacation and would like to turn their photos into a slide show with titles and music, as Google photos doesn't do it. Leo says that it used to be a thing that Google would do. Any presentation manager would, like Apple Keynote or Microsoft Powerpoint. Corel makes the best one though: Corel PaintShop Pro Photo. But you can also use Corel Video Studio to do it. Here's how - https://learn.corel.com/tutorials/videostudio-create-slideshows/.
Rob wants to know what he can use now that iTunes is going away. Leo says it isn't going away; it's just being divided into Music, TV, and Photos. The sync is being incorporated into your OS now, which Leo says is the best part of the whole idea. But an alternative is VOX on the Mac. Leo says it's a third-party music player that plays high-resolution music.
