Apps, Operating Systems (Windows, MacOS, Linux), or pro level software.
James says that on his Mac, Apple has taken away the color icons in the sidebar. Jason says that sometimes Apple just decides to break stuff because they know better, or it fits into their overall plans for the software — removing features while bringing in others.
Jason recommends checking out an application called DragThing. This would allow James to have a separate dock where he can put more applications. Then he can stop using the Finder sidebar for that.
Victor would like to update Windows XP. Jason says that XP updates are still available but are usually just on an exploit by exploit basis. He recommends getting all the updates he can and install them. But after that, he should seriously consider not using that XP machine online because it won't be regularly updated.
Steven has an old MacBook Pro that has Windows 8.1 installed with Boot Camp. He'd like to dump Windows now and get that space back. Jason says he can open Boot Camp Assistant and click through to the partition utility and use it to remove the partition. He'll just need to click "restore." That will allow him to restore his Mac to its original configuration. Sometimes that doesn't work, though, so he can delete the Windows partition in Disk Utility as well.
Bruce has a lot of data on a bunch of hard drives and he's looking for a way to catalog or collate the data, getting rid of duplicate files. Leo says there are de-duping tools that are designed to analyze and get rid of duplicates, but he'll run a risk of deleting something that only looks like a duplicate.
Kate wants to learn about genealogy. Leo says that computers and online services like Ancestry.com are great for that. Genealogy.com is another source. EllisIsland.org is another good option if she's looking to see when her ancestors immigrated to the US through Ellis Island. And, don't forget the local library.

Mary has an old XP computer and she's worried about getting the WannaCry virus. Can she get a patch to protect herself? Leo says that Microsoft has ended life for Windows XP, but did make a patch for it and she can go into Updates and get it. But according to Leo, 98% of infected computers with WannaCry are Windows 7 computers. So XP isn't even on the radar. It doesn't hurt to be safe, though.
Andy has an iPhone SE and he noticed that he can text phones from his PC using the email address provided by the carrier. Another option is to use a texting app that has a desktop app as well. Options include WhatsApp and Telegram, but he'd only be able to use it with people who use those apps. Facebook Messenger is an idea though. It works in the browser as well as mobile device.
Mary wants to make youtube videos and create a cookbook. Leo says there's a great cookbook menu system called Paprika, which not only allows you to create a cookbook, but you can surf recipes and save them to it. It's brilliant.
Micah uses Audacity and he gets an intermittent hum on his microphone. Leo says that the mic Micah uses is USB and so a hum can't really find its way into the chain because the power is coming from the laptop, not an analog phantom power source. It could mean that the Digital to Audio converter is going bad, but if there's no analog loop, then there can't be a hum. So it must be software.
