Jack got an antivirus notification that an Apple TV that was trying to access his network. He said no, but it keeps requesting it. Leo says that if Jack has an Apple TV, it's probably trying to connect. It uses a utility called BONJOUR to connect. It's perfectly safe to talk to your mac. And since Jack has a router, his router is a perfect firewall to prevent outside connections. That's how he'll know it's the Apple TV that's trying to connect. So let it. And get rid of the AVS.
Terry edits 4K video with his iPhone 11 Pro Max. But when he makes changes, the upload to his iMac is very slow. Leo says that no online backup is going to use all the bandwidth you have to backup. And your upload speed is always drastically lower than your download speed. Leo says that Apple does offer iCloud backup on your mobile phone, but it's only 5GB for free, and the data isn't private. You can buy extra bandwidth, however. Leo recommends also backing up directly to your Mac.
Bird has 15 Macs at work that he has to set up. He wants to know if he can do a net install to create a setup when connecting the Mac to the network?

They are the leaders in network Mac management.
Do not open email attachments, as they are one of the most common causes of innocent computer users getting infected with malicious malware. Email attachments are "the kiss of death." Ask the sender to place the attachment in Dropbox, etc. or other safer alternatives. Furthermore, Mac and Windows 10 users can open PDF files by themselves, so no need to download and install additional software like Adobe Reader. There are too many vulnerabilities these days regarding email attachments and outdated Adobe software.
Caller wants to dual boot into Windows with Boot Camp, but it's telling him that he doesn't have an Intel processor, so it won't work. He bought a used Mac, what gives?

See if that works.
Gary misses the program Little Snitch. Leo says it's a great program that watches outbound traffic, and it's still around. Is there something like that for Windows?

LeAnn has an older Mac laptop that she wants to upgrade. Leo says the best thing to make your old Mac faster is to get an SSD drive. Adding more RAM will boost it as well. Should she downgrade to OS X Sierra? Leo says that High Sierra is actually faster, so there's no need to downgrade. But make sure to back up the existing hard drive before changing out.
Bruce upgraded to an LG C7 TV, and it's been the best TV he's ever owned. He has an older generation Apple TV, not the new 4K version that's out now. He's wondering if it would be better for him to get a Mac Mini instead. He wants to know what the difference would be between Apple's tvOS and macOS. Leo says the new Apple TVs support UHD and high dynamic range (HDR). One of nice things about using an Apple TV is that it's automatic, Bruce would just have to plug in the HDMI cable and everything would work. The other thing it does is Dolby Atmos sound.
