Why Can't I Run the Windows 11 Compatibility Checker?

 Windows 11

Episode 1835

Larry from San Francisco, CA

Larry tried to see if he could install Windows 11 last night and had problems with secure boot enabling. Leo says that secure boot is in the BIOS and it should have been turned on when Larry installed Windows 10. So that means it had to have been turned off recently. Windows also will need TPM 2.0 to support Windows 11, so Larry's computer could be too old to support it.

Why Can't My New Mouse Work With My Old Mac?

2007 iMac

Episode 1777

Andrew from Moorpark, CA

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. 

Why Doesn't ATSC3 Work With My DVR?

ATSC 1.0 vs 3.0

Episode 1765

John from Nashville, TN

John has a TV with ATSC 3.0, but ATSC3 doesn't work with his DVR. Only the ATSC 1.0 side works. Leo says that most broadcasters aren't even using ATSC3 yet. It could be an incompatible file format. If your DVR supports ATSC3, then Leo says a call to the manufacturer is in order. Welcome to the world of being an early adopter. It's the early days of ATSC3 though, so in time, the issue should correct itself.

Will the M1 Apple Silicon laptops work with GNU utilities?

Apple M1 Chip

Episode 1749

Ralph from Orange County, CA

Ralph wants to know if the new MacPro M1 laptops will still run GNU utilities and have command-line access. Leo says a lot of them won't work. Some can run under Rosetta, but others don't. So it depends on what you want to do. But Leo also says that those incompatibilities will be fewer and farther between as developers put out new versions in time. Many will also go to native apps.

Why can't I use Internet Explorer to visit Yahoo?

Google Chrome

Episode 1510

Michael from Fountain, CO

Michael is getting a message from Yahoo that he will lose access to his account if he continues to use Internet Explorer 11. Leo says that's the most recent version so that doesn't make any sense. But if Yahoo is not going to support Internet explorer anymore, then what may be happening is that Robert has compatibility view on. Michael should go into IE Tools and uncheck "use Microsoft compatibility lists." That will send a mixed message to Yahoo that he's using the wrong version.

Why did my TV stop supporting 4K streaming?

Vizio 4K TV

Episode 1499

Richard from West LA, CA

Richard got a Vizio 4K TV and suddenly it says his TV isn't capable of receiving 4K, when it has been for the last two years. Leo suspects there's a "handshake" problem between the DirecTV box and the TV itself, and it's usually the culprit of HDMI cables. He should try replacing the cable first. But he'll have to be sure to have a cable that is certified for high speeds of 18GB per second. Amazon sells them for about $10. He could also try another HDMI input to see if that fixes it.

Episode 1487

Tom from Hawaii

Tom uses Ubuntu, and lately, he's ran into issues updating his HP computer. Leo says that Linux only works on a computer that has drivers that are written for it. When people update, they may run into issues where their drivers have been "broken." It's often a video driver issue. Starting over and trying again will cause Linux to choose the right driver and continue. But if not, then it's a driver or hardware compatibility issue.

Why don't my apps run after a Windows 10 update?

Microsoft Windows 10

Episode 1438

Dave from Wichita Falls, TX

Dave had a problem with a Windows update and he realized that if he deleted another program that Roxio installed, then it worked just fine. But now several programs he relies upon don't work. Leo says that it could be a problem with apps that are 32-bit, though Windows 10 still supports them. Microsoft may have killed off third-party 32-bit support. There is a program compatibility troubleshooter in Windows 10 Control Panel. It could walk him through how to run his app in compatibility mode.

How can I get the Windows 10 update?

Episode 1252

John from Biddeford, ME

John got a laptop with WIndows 8 Pro that he got for free through college. He wants to upgrade to Windows 10, but he hasn't gotten the invite. Leo says this is because he has a version that can't be upgraded to Windows 8.1. Leo recommends running the compatibility checker. If he passes that, then he can download the Windows 10 ISO and install it directly without an invitation. But he should make sure that he's compatible first. John should also run the updates until he's completely up to date.
