Hi @mattyb_27, and welcome on the forum! This is a known issue that has to do with youtube, not with Justin Guitar.
There are different ways to work around this:
- you can lower the privacy settings in Safari (which I wouldn’t recommend)
- if you have clicked to start the video and you have gotten the ‘sign in’ screen: reload the page to get rid of the ‘login to prove you’re not a bot’-message, then either click on ‘watch on youtube’ in the bottom left hand corner of the video or on the title of the video at the top of the video window. It will take you directly to youtube instead of playing the video embedded in the JG webpage - bit annoying, but it works.
And if it’s any consolation: you’re not the only one having this problem:
