My daughter has a 27" iMac with a new unknown window which appears and will not go away. Had her run malware bites and disk utility for repairs and full restarts with no change. Always re-appears after a couple of minutes of a shutdown or restart. Has option to say OK but does nothing. Clicking on window to close does nothing. Can move window to edge of screen only. Anytime mouse goes over this window the color wheel is spinning. Had her open Activity Monitor and nothing is red marked or looks unusual from what she has remotely shown me. I am attaching two screen shots. One of her iMac info with OS version. Second of "Strange Window". Has anyone had this happen or know how to remove it completely if you know what it even is. I am personally at a loss as to what next to have her try . Thanks group.
