The ability to prevent the installation of new system software versions on Apple mobile devices allows users to maintain a specific operating system environment. This functionality is relevant in scenarios where compatibility with existing apps or specific device behaviors is paramount.
Controlling when an operating system update occurs provides stability and predictability. Historically, some updates have introduced bugs or altered functionalities that negatively impacted user workflows. Postponing the installation ensures that the user retains a consistent and potentially more reliable experience. This control also allows for a period to assess community feedback regarding new releases before implementing them.
