Do I have to upgrade to macOS Catalina before Big Sur?

macOS Big Sur

Episode 1736

Stan from California

Stan wants to know if he should wait until Big Sur or upgrade to macOS Catalina now? Leo says that you have to upgrade to Catalina first, since it eliminates all 32 bit apps. This will give you time to convert your other 32 bit apps to 64. It'll be pretty straight forward. But moving up to Big Sur may be more problematic because of how they approach kernel use. But you could wait and see what happens and stick with Mojave until Big Sur comes out and then see if you have to. Why do it twice if you don't really have to?

Elgato EyeTV

Episode 1730

George from Houston, TX

George is having issues converting his old VHS videotapes to digital. The old app that he's using, called the Elgato EyeTV isn't capturing the video. Leo says that the new eyetv company is now called Corsair and he says it's a good company. But there's likely no new driver for and old version of the software to support the latest macOS. Mac recently went to 64-bit only, dropping support for older 32-bit versions of the software. So you may need to buy the latest 64-bit version. But there should be a try before you buy option. So download it first and see. 

Can I Upgrade to 64-bit Windows?

Windows 10

Episode 1578

Storm from Texas

Storm bought a computer in 2007 and has been updating it until Windows 10, where it won't upgrade because of her GPU. Now she's replaced her graphics card and Windows 10 finally installed!  But she wants to know if she really has a 64-bit system. She looked at the specs and sees the phrase X64, which Leo says indicates 64-bit architecture. Upgrading also depends on how much RAM she has. So if she feels limited, then go to 64-bit in Windows 10.

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.

Episode 1383

Greg from Aspen Park, CO

Greg has an employee who downloaded the 32 bit version of Windows 10 and installed it by mistake, rather than the 64 bit version. Can he reinstall it? Leo says that he'll probably have to wipe the drive and install from scratch. So he should make sure to backup the data first and then format the drive. He can't just upgrade on top of it, unfortunately.

Should I be running Windows in 32 or 64 bit?

Episode 1167

Sean from Burbank, CA

Sean bought a used HP Touchsmart computer running Windows 7. He's planning to restore it and wants to know if he should change the OS to 32 bit or keep it at 64 bit. Leo says it doesn't make any difference except for the amount of RAM he has. If it has more than 4GB, then he should keep 64 bit. If not, then go for 32 bit.

If he runs into issues with Windows Genuine Advantage, he may need to contact Microsoft. Is 64 bit faster? Leo says not always, in fact, in some cases it can even be slower. But with a massive amount of data, using 64 bit is faster.

Why doesn't the Samsung Galaxy Note 4 run in 64 bit?

Samsung Galaxy Note 4

Episode 1124

Alan from Los Angeles, CA

Alan is thinking about getting the Samsung Galaxy Note 4, but hears that it won't run 64 bit software. Leo says that really doesn't matter. All 64 bit can do is address more memory and handle larger chunks of data. But he doesn't really need 64 bit. Samsung is only doing this because Apple did it last year. There's no real benefit for a mobile phone right now. This is more likely the difference between the Xenos Opticore Processor (in Europe) and the Qualcomm Snapdragon (in the US).

Episode 993

Steve from Ohio

Steve bought a new laptop with 32 bit Windows 7, but he can't see all of his RAM. Leo says that's because 32 bit will only see 4GB of RAM, so if he has more than that, he'll need to go with 64 bit Windows 7. Can he install it over the 32 bit? Leo says it's better to format the hard drive and start over. The chatroom says that he doesn't need to buy another copy, just download it from Microsoft and use the same License key.

How can I move all of my 32 bit software to 64 bit computers?

Episode 966

Dudge from New Jersey

Dudge is having a hard time moving to 64 bit. Leo says that the only advantage of 64 bit is to address more memory for gaming, video editing apps, and the like. If his software works fine in 32 bit, then there's no real reason to go to 64 bit. Leo says to keep using what he has until it stops working. When it stops working, upgrade everything.
