iCloud and Keychain
Every second or third day, I get a message on my Mac stating that some functions of my iCloud will not be available unless I sign in again.
Now, I remain signed in, and every-time this message appears, it is my keychain that is suddenly "unticked". Even if I go through the process of singing in again into iCloud, and tick the bloody box, it appears ticked and the next moment it is unticked and greyed out again.
I do use the same iCloud account on my iPhone and MacBook Pro.
Please help, this is getting ridiculous.
