Modal window design – Apple concept

Концепт нового окна оповещения на основе существующего окна в Human Interface Guidelines от Apple.

"An alert appears when the system or an app needs to warn the user about an error condition, or a potentially hazardous situation or consequence. An alert is modal within an app unless it pertains to a single document or window, in which case it’s displayed as a sheet."
