Question: Changing email address caused problems with iMac
Several days ago, I changed my email address with Apple. No problem with my iPhone or my iPad. I was even able to order music and a movie with my new sign-on and password. But, ever since I made this change, I keep getting irritating pop ups on my iMac that say This Mac can't connect to iCloud because of a problem with "(my old email address)" Open iCloud preferences to fix this problem. I click the iCloud preferences button and nothing happens. It just sits there, wheel icon spinning, trying to open it. Appreciate any help you can give.
iPhone 5s, OS X Mavericks (10.9.4), iPad Air
