Impossible to set up iCloud mail address?
I know the procedure to set up iCloud mail account. I have one on my personal computer.
The following happens on an iMac and Macbook Pro (High Sierra 10.13.3) for one owner.
When at "choose an iCloud email address" and after input of the address with OK, the "Create" window is showing a yellow warning sign. After pressing"Create", I come always back to the previous window without any particular message! The chosen address seems to be correct. I am turning in a circle of these two windows.
Could somebody help? Thanks very much
