John is about to retire to Portugal. What computer should he upgrade to before he leaves? Leo says you may not have to. Try replacing the spinning drive in your current computer with an SSD drive. Leo also says to boost your RAM as high as you can afford. Both those moves will greatly increase the performance of your existing computer. These days new processors haven't increased in speed like the old days. The processing power has been largely incremental.
Al has a 2015 Macbook and he's running out of space, so he can't install Big Sur. Leo says that Al should get an external drive to copy off his data to free up space. Maybe even make a bootable copy of the hard drive and then start from scratch with Big Sur after erasing the drive. Then restoring the data. So get a terabyte external drive and try that. Time Machine is also a good option with that external drive. That's Apple's own way.
But is Big Sur worth it? Not for an older Mac. So if he's up to Catalina, that's good enough for that 2015 Mac.
Richard is having issues with Windows XP and his password. Leo says that Microsoft has stopped supporting Windows XP, and Richard shouldn't use it online anymore. And if Richard can't use some of his programs, it's probably time to move on to new versions. Office, for instance, Leo recommends using Office365. FrontPage is dead. Money is dead.
Leo says Richard needs to upgrade to Windows 10 if he wants to do anything moving forward and look for more updated apps for the apps he's been relying on with that old machine. The web has just moved on.
Mike recently upgraded his old Acers to Windows 10. But after running the Microsoft System File Checker, he's having issues accessing features in his account, particularly settings. So he did a repair reinstall. Now he can't get back online to the Internet.
Leo says to go into the device manager (Windows + X) and see if any devices are missing or have a red "x" or "!" in the corner. It could be a driver issue. Also, look in the settings to see if sleep is enabled and turn it off.
But your WiFi card may not be supported anymore. Luckily, they're cheap.
Walter has two computers running Windows 10, but every time it upgrades, it forces him to reinstall his printers, even though he uses Google Cloud Print. Leo says that Google Cloud Print is going away because most printers now print wirelessly via WiFi. But they do recommend installing CUPS drivers. It's odd though that Windows breaks the connection to a wired printer when updated. Print directly via WiFi. It'll not only be easier to print, but it should also be easier to update. Look for a CUPS driver for your printer. That may be the easiest solution.
Jim was updating Windows 10 when his network turned off suddenly. He turned it back on, and Windows turned it off again! What could be causing that to occur? Leo says that your computer can go to sleep when it's not being used, but your devices can fall asleep as well. Leo recommends looking into the driver properties and see if there's a sleep option that's been enabled. If it has, turn it off. Leo also recommends upgrading to an external wifi card for your computer.
Steve has upgraded an older Toshiba Satellite to Windows 10, but he lost his favorites when he updated. Leo suspects that the favorites are still in Windows Explorer, but EDGE is the dominant browser in Windows 10 and probably didn't bring them over. But you can open Explorer using the Windows key and if they are there, you can export them into EDGE.
Tom wants to know what is the advantage of updating to macOS Catalina and can he? Leo says it depends on how old the Mac is. He may not be able to go all the way up to Catalina! In general, he wants to stay up to date. But that one caveat is the 32-bit issue. Check out this link - https://support.apple.com/en-us/HT208436
Fred uses a Windows PC, and he's having trouble updating to the 1903 update. He had a similar problem a few years ago during the Anniversary edition. He just can't update it. Leo says he's heard several are having issues like that and it could be something unusual that is uncommon about his computer. It could be hardware related, but also quite likely a unique computer program that he has installed. Leo suggests unplugging any external USB peripherals like a printer or external hard drive, then try the update.
Jerry has an Android mobile phone and after an update, he lost the use of both his cameras. Can he roll it back? Leo says that the upgrade probably didn't go well and failed, so try upgrading it again. You don't really want to go backwards because of security. Leo recommends doing a factory reset to wipe the phone and reinstall the OS. Be warned though that this will wipe the phone of all data apps and photos, so back it up to Google. But in most cases, that fixes the problem. If that doesn't work, the only way to go backwards is to root the phone.
