iCloud gives "stopped responding" message
When I try to use Photos, Drive, Pages or Keynote via the Cloud in Safari I receive a message that the app in question has stopped responding. I receive this message about 10 to 15 seconds after I open the Cloud web page.
This happens on my iMac, in Safari. I have no problem when in Firefox on the iMac. Nor do I have a problem on my MacBook Pro in Safari.
So it seems to be specific to my iMac in Safari.
I have tried clearing the Safari cache, quitting Safari, and restarting my iMac (several times). Can anyone help?
