Mark wants to know if he can check out Linux on his iMac. Leo says in theory, yes. But Leo's experience is that they don't really work hand in hand well. Do some research online to see which version of Linux works best on a Mac. Then put that version on a USB key, then boot the mac holding down the command key. That'll give you a list of drives to access, and then you can run Linux on the USB key to see if it works.
Stan is having a computer display issue. He has issues when he plays video. But when he uses Linux remotely, he has no issue. But when he's on Linux directly, he has an issue. Leo suspects that there's an issue with the video card. Maybe an incompatible video driver. You could remove the driver, and reinstall it. Or, get an inexpensive video card and see if it fixes the problem. Leo says that using a different flavor of Linux, like PopOS could also solve it.
Tom wanted to learn Linux, so he loaded up Linux on his PC. After a month, Windows now wants to install a feature update 1903 and now he's lost a partition. Leo says that Windows is being "bossy," thinking that it's the only OS you should have. So it "clobbers" your boot record and causes a boot-up issue. It's a common, yet complicated issue. You need to have a boot manager to sort it all out. Leo recommends GRUB. It gets loaded first and then asks you which OS you want to use. Most likely, the update redid the master boot record, damaging it.
Dave recently migrated to Windows 10. He isn't very happy because he has ads on his machine now. Leo says that Microsoft did put ads in the signup menu, but he can turn it off in the settings. His printer also isn't supported anymore. Leo says that any company will eventually end the life of their technology, and not support it anymore. So that's likely what happened. Not really Windows fault, but another option he can try is to convert his computer to LINUX. Leo likes PopOS. Debian. and Ubuntu.
Manny has a 17" Dell laptop running Windows 7. With Microsoft stopping support for it in January, he's concerned about it. Should he turn it into a Linux laptop? Leo says that if you can put Windows 10 on it for free, then it would give it a few more years. But if you have to buy Windows, Leo would advise not doing that and going with installing Linux on it. Leo likes PopOS by System 76. If that doesn't work because it's a bit heavyweight, then Xubuntu or Lubuntu is designed for older machines.
Joey wants to know if Linux has a built-in VPN. Leo says no. He will need a provider to handle VPNs, not just software. Leo recommends visiting the Wiki for ARCH, a version of Linux. There's a great list of clients, carriers and servers that will run on Linux. That's the best place to start. Where can he get apps to download for Linux? Leo says that PopOS has its own "store," called the PopShop, which is an app that will help to install software.
John's first computer was an ACER Aspire laptop. He wants to upgrade his operating system, but he isn't sure if it's 64 bit or 32 bit. Leo says that Intel was using 64-bit architecture long before everything moved from 32 bit, so he'll likely have it. But John is having trouble finding drivers. Leo says that companies that stop development often don't offer those drivers online, so many driver archives have sprung up. But often users don't get what they think they are getting. And Microsoft usually stops writing security updates for old computers, making them a security threat online.
Mike resurrected an old computer to look through some old floppies, but they're password protected and he can't remember the password. Leo says that if Mike can figure out how he password protected it, that could give him a clue. But floppy disks weren't normally password protected. So it's an odd thing for a password pop up to happen. It may be possible to examine the disk using a Linux computer. That could lead to being able to read it. But not for very much longer, as Linux will not support floppies moving forward.
