Q: Error message: "This action could not be completed. Try again."
This message appears when I try to login to iCloud through System Preferences or AppStore. Though it is ok when I do it in Safari (applied.apple.com or iCloud.com) or in iTunes...
It happened after I upgraded to El Capitan
Tried quitting iCloud, it erased all data from MacBook, but still don't let me in... The same message.
Reset keychain. Now I can't login to Facebook, Twitter and some Exchange Accounts in Internet Accounts (System Preferences)...
Nice new system...
Any ideas?
