Delay iOS updates on Supervised devices with iOS 11.3

Written on 03. Feb 2018, 08:56

As with all iOS x.3 (i. e. 9.3, 10.3) updates, Apple addresses mainly enterprise users. This time, Apple integrated a new useful functionality that will make IT departments feel relieved: on devices with iOS 11.3 there is a possibility to delay system updates for up to 90 days. The release of iOS 11.3 is expected for Spring 2018.

New configuration option „enforcedSoftwareUpdateDelay“

With the release of iOS 11.3 a new configuration option will be integrated, which can be used to delay iOS system updates for up to 90. The new option is called „enforcedSoftwareUpdateDelay“. This option belongs to the section „restrictions“. As description Apple added the following information:
Supervised only. This restriction allows the admin to set how many days a software update on the device will be delayed. With this restriction in place, the user will not see a software update until the specified number of days after the software update release date.
The max is 90 days and the default value is 30.
Availability: Available only in iOS 11.3 and later and macOS 10.13.4 and later.
Therefore it is possible on Supervised devices (no matter if activated using Device Enrollment Program or manually via Apple Configurator) to prevent the update for an specified period between 1 and 90 days. Previous approaches, for instance blocking the connection to the Apple update servers using a proxy, seem to be obsolete from now. The setting can be deployed on the devices using a compatible mobile device management system.

Advantages of the new solution

The IT department in companies are gaining more time for testing releases of iOS beforehand. This can be positive especially in cases where companies are using custom apps. The additional time can also be used for fixing bugs. Although the new option can delay updates, a general option to prevent iOS updates is not available (and won‘t be available in the future).
