Hi everyone. I had been using fastest tube/kwizzu to download videos and audio of youtube for years without any issues. Worked great and was suggested on this site. Doesn't seem to be working anymore, at least not with Sierra. Wondering what the latest and greatest is to download videos and audio? I've read up on MacX, 4K, and Clipbrag. Are there any others I should look into or are these the go to apps you guys use? Not looking for anything fancy, just download videos or audio from youtube. Thanks everyone!
