Apple ID not working on my MacBook air
My apple ID is not working on my 2015 MacBook air. It was working fine previously till I changed password through my phone.
Running 10.13.6
I can log on through Safari browser but not iCloud, iTunes or FaceTime. They all say there's an error and won't log on.
I am able to change password through my phone 7 and access iTunes through there with no problem.
Reset password several times but still no luck.
MacBook Air, Mac OS X (10.6.8)
