Hello

I can't login to my minecraft account on my macbook. i got a new computer for about 5 months ago. i could easily play minecraft on it without problems. But one day i logged out, i couldn't join again. i changed my codes and email, but im pretty sure it's my device whos the problem. when i try to join it says "Sorry! make sure you are online, and try again". i am online. i also have an windows computer, and i tried to login the minecraft acc on that yesterday, and i got in. But as soon i try on my macbook, i cant. 

so if anyone has some knowledge for an macbook who cant join minecraft, please reply. thank you. i have linked my Log, so you can have a look on it too.
