I am trying to uncheck "Enable Messages in iCloud" from the Message Preferences on my MacBook Pro, I get the "Disable Messages iCloud?" confirmation box with 3 choices - Disable All (devices), Cancel, Disable This Device, I click Disable This Device, but it just keeps popping up the same "Disable Messages iCloud?" panel - over and over and over. How do I fix this, I really want to disable Messages in iCloud on my Mac temporarily? Thanks!
