Late final month, Apple issued an uncommon standalone software program replace to Macs working macOS Massive Sur known as “Machine Assist Replace,” which it stated was to “guarantee correct updating and restoring for iOS and iPadOS gadgets with Mac.”
Whereas no different particulars had been supplied, it was assumed that the replace added help for lately launched gadgets, together with iPhone 13 fashions, the brand new iPad mini, and the ninth-generation iPad. Nonetheless, the replace was the primary of its form to come back via System Preferences -> Software program Replace, which made some customers inquisitive about it.
Normally whenever you join an iPhone, iPad, or iPod contact to a Mac, a dialog pops up from an app known as MobileDeviceUpdater that claims “A software program replace is required to attach” to your iOS system. This usually occurs when the system has been independently up to date with a more moderen model of iOS or iPadOS that the Mac would not acknowledge, indicating that the obtain is required in your Mac to speak with the system.
It seems to be as if Apple has now chosen to scale back the reliance on MobileDeviceUpdater by routinely delivering these downloads when they’re prepared through Software program Replace, so customers now not have to attend till they plug in an iOS system to get what’s now known as a “Machine Assist Replace.” The change is probably going an effort to scale back the frequency of the MobileDeviceUpdater dialog popping upon connecting a tool, which can strike some customers as some form of malware.
The change was helpfully confirmed by Tidbits‘ Adam Engst, who sat on the mysterious Machine Assist Replace for every week or two to confirm what it was.
I acquired that likelihood in the present day once I plugged in my iPad Professional and acquired the same old MobileDeviceUpdater dialog. I made positive that Software program Replace was nonetheless providing me Machine Assist Replace, after which I allowed the MobileDeviceUpdater dialog to replace my Mac. After closing and reopening Software program Replace, the Machine Assist Replace possibility was gone, confirming that they are one and the identical.
As Engst notes, this is not an earth-shattering discovery, however it’s good to know what occurs when putting in future Machine Assist Updates from Software program Replace: They do not require a reboot, and customers will nonetheless get a MobileDeviceUpdate dialog the subsequent time they plug of their system in the event that they have not acquired round to putting in the replace.
