alright guys so if you haven't been on Twitter or following the tech news recently then you might not know that something very serious happened last night I guess so sort of in exploit and it's not even really an exploit because it seems too simple it's a problem essentially on every single Apple computer running the latest software running hi Sierra you can get in to anybody's laptop without the password it's incredibly simple to do anyone could do it you could do it it's not just a local scenario where a person gets in front of your laptop and unlocks it without you knowing this could also be an issue on public Wi-Fi if you might have screen sharing turned on for example and someone can come in and potentially access your device remotely now the reason for making this video isn't strictly to show people how it happens but also to inform you so that hopefully you can make the changes necessary so you're not susceptible but also so you can share it and let anybody in your life with a macbook know that they need to update their system real quick so I'm using wills laptop he updated his to high sierra and let me show you what i'm talking about so i'm logged in right now but if i go to system preferences users and groups you'll see will is the only admin on the system but if i click this little lock in the corner here get rid of wills username and just type root all lowercase and then enter it unlocks the whole system I can do anything now I could change his password I could create new users I have complete access now you might be saying well he's already logged in so is that really such an issue well let me take it a step further for you if I log out of wills account and then just pick a guest user for example as a guest user you should have no authority whatsoever but if I go back up here now to System Preferences users and groups I hit the same lock icon use the username root again no password it unlocks the whole deal so I can select wills user now and reset his password completely I could set it to anything I want all of Wells information is available to me everything he's got in there it's a complete unlock I'm in I got access to all what are you trying to hide well but all joking aside this is serious stuff this is like the highest level type of issue you could ever run into all your passwords anybody out there with a password on a Mac running this version of High Sierra you have no security right now essentially no security now the word is that Apple's aware of this and they're issuing a software update so the main thing here is go and look on your system right now if you're on high sierra and look for a new security patch if it's there it will say in some kind of heading like important update do this right away alternatively you can change the password to the root account of your system which seems like a good idea right now so just add a password to that user that isn't a blank field obviously so there it is a little public service announcement run the update if it's there and as I said let people know all right everybody knows somebody with a MacBook so tell them they've been otherwise they're out there like a sitting duck
