User impact: Admins may experience issues within Microsoft Intune with Rapid Security Response version of iOS/iPadOS and macOS.

More info: Impact is specific scenarios are limited to Apple devices that take the Rapid Security Responses update iOS: 16.4.1 (a) and macOS: 13.3.1 (a) with an alpha “(a)” character in the OS. Examples of impact may include:

– Admins may be unable to create new compliance policies to check for the new iOS update which has an “(a)” added to the version string. Existing policy checks are unaffected. NOTE: This impact has been remediated.

– Admins may be unable to create a policy to block conditional launches based on OS version with the character “(a)” for Mobile Application Management (MAM), and are unable to check for the new version or validate whether an application can launch or not.

– Enrollment restriction policies may not work as intended with non-numerical character versions for Apple products.

– Reports with build-specific values will report OS without the “(a)”.

For Mobile Device Management (MDM) admins can use Microsoft Intune update controls to set the required version to latest to get the security update.

For Mobile Application Management (MAM), users should update to the latest version when possible while we continue to engineer supported solutions.

Current status: Admins can continue to specify the Apple Rapid Response Update for their respective platforms by using the build version in their compliance policies for minimum and maximum OS targeting. Our fix that’s designed to address the remaining MAM issues has been deployed and is being applied to the affected applications. We’re expecting that impact will be remediated by our next scheduled update.

Scope of impact: This issue may impact any admin attempting to perform the actions outlined in the More info section of this update.

Start time: Monday, May 1, 2023, at 12:00 AM UTC

Root cause: Apple recently introduced a change to how their versions are specified, causing a need to change how our originally supported processes work in relation to iOS/iPadOS, and macOS.
