I think I know why I cant restore my new phone from my backup. When I last backed up before the upgrade, it has an option to "check" encrypted or whatever and I checked it...I don't know why. So it's been asking for my password to restore to my new phone, and it keeps saying my password doesn't match which I don't get because I could use that password to unlock my Mac. When I unchecked the box, it's going through but not restoring since it still needs a password for the original back up I think.
There's a "lock" image next to my last backup when I click on devices. Any tech savvy people know how I can decrypt it?
