Software Update Required" loops/fails when connecting iPhone 12 (iOS 27 RC) to Mac (Tahoe 26.6.2)

Hi everyone,

I am encountering an issue where I cannot connect my iPhone 12 to my Mac.

Environment:Mac: macOS Tahoe 26.6.2 iPhone: iPhone 12 running iOS 27 RC

Problem:When I connect the iPhone to the Mac via USB, a dialog pops up stating, "A software update is required to connect to your iPhone.

"I clicked "Install," but the download progress bar gets stuck at "Downloading 1 item...".

After a short wait, it fails with the following error message: "Installation failed. Can’t install the software because it is not currently available from the Software Update server. "As a result, the iPhone 12 does not appear in Finder or Xcode.Notes:Internet and Safari connections work normally on both devices.

I can log into my ADP account via Safari without issues.

In the past, this "Software Update" prompt succeeded smoothly with older iOS updates.

Has anyone else experienced this with iPhone12 & iOS 27RC on macOS Tahoe?

Any insights or workarounds would be greatly appreciated. Thanks!
