Apple has released a device support update for macOS Big Sur that is separate from its regular update schedule. The release notes state that this update ensures proper update and rollback for iOS and iPadOS devices with a Mac.
Apple does not provide any specific note on the update, but since the new iPhone 13, ipad mini, and ninth generation iPad debuted recently, it could be related to these products. The update is 195.6MB and is not listed on Apple’s Big Sur support page.
If you are using your Mac to back up your iPhone and iPad (regardless of which model you are using), you need to install this update. As with all updates, we recommend that you back up your Mac before installing in case the update causes problems for your Mac and you need to restore your data.
To install the update, go to System Preferences and click on Software update, then select the Device support update and Install now. You may need to click More information on the update page if you are enrolled in the macOS beta program. The installation will take a few minutes but a restart is not required for this update.
The last time Apple released a Device support update took place in 2019, which was also related to proper update and rollback for iOS devices using iTunes for Mac.
