iCloud Photos effect on MAC Photos after canceling?
According to an email from iCloud.com, "You must download your full resolution photos and videos to at least one device before they are deleted from iCloud Photos in 30 days." Do I really need to do this? The email came after I turned off iCloud Photos on my MAC. My MAC was the only device that had iCloud Photos activated. It was not activated on my iPhone or iPad. Did iCloud change all my photos and videos on my MAC to low resolution versions when I activated iCloud Photos?
