How can I make sure open source software is safe?

Episode 1296

Dave from Concord, CA

Tony wants to know how to check to be sure the ISO of open source software is legit. Leo says that an ISO is found to be legit by signing. A hash has to be generated in order to provide proof of a legitimate ISO. If the ISO has changed, then the hash would be modified. There's also a signing key, which is based on GPG encryption. It has to be authenticated by the developers of the software.

Why can't I upgrade to Windows 10 on my Mac?

Episode 1251

Carlos from Santo Domingo

Carlos has been trying to upgrade to Windows 10 on his Mac and it keeps asking for a CD instead of installing with the ISO. Leo says it may be a bad ISO. Boot Camp Assistant will automatically install it. Microsoft will also allow him to download a Windows 10 ISO and it will verify the ISO to be sure it's valid. He can also use this app to download any missing drivers (thanks to Beastmaster in the chatroom).

How will Windows upgrade to Windows 10?

Episode 1198

Alan from Houston, TX

Alan would like to take the existing system he has and wipe it to get ready for the upgrade to Windows 10. He's wondering how Microsoft is planning to do the upgrade. Leo says that there will be a clean install upgrade available, but nobody really knows how it will work. Paul Thurrott has an article on it. He'll download an ISO disc image, put that on a bootable USB (great idea) or burn it to a DVD, save the key, and activate it. It'll be pretty straight forward.

How can I stream my pictures to my Apple TV?

Episode 1033

Bernie from Lakewood, CO

Bernie has a bunch of old slides that he transferred to DVD, and then ripped them to his Network Attached Storage, along with image files of discs (ISOs). How can he view them on his network? Leo says that VLC is an amazing video product that will allow him to view it.

What about Apple TV? Leo says no, it can't understand ISOs. But Bernie can use his Mac with Mountain Lion or later to airplay them to Apple TV. He can just open the ISO with a Mac program like Disc Utility and then once it's mounted, he can stream it from the Mac using AirPlay.
