Tuve este problema después de actualizar de Yosemite a El Capitan. Me había metido con mis KeyChains (probablemente el factor probable en este problema).

Para resolver el problema, tuve que borrar por completo mi Macbook Air, configurar El Capitan e iCloud nuevamente. Antes de intentar hacer esto, asegúrese de tener una copia de seguridad de todos sus datos en una unidad externa, no una copia de seguridad de Time Machine.

Como puede ver a continuación, CloudKeychainProxy ahora no está acaparando los ciclos de la CPU, y la duración de la batería ha mejorado drásticamente.
