Why the thumbs down, when all the meetings are over? 😀
Sunday afternoon marked my farewell to macOS 27 Golden Gate beta 2, and I will miss Siri AI. The lead Genius downgraded to Tahoe using DFU mode with Apple Configurator 2 and a MacBook Air, connecting my MacBook Pro m4 pro with various cords and equipment. He suspected the beta’s bugs disrupted an iPhone backup file for my old iPhone 📱, and he observed the issues occurring when my MacBook Pro displayed the -40 problem in Apple Configurator. Few people encounter this error message when restoring backups or reviving an iPhone. The process took four to five hours for DFU restore, setup, Time Machine backup restoration, and then Apple Configurator backup restoration to my iPhone on Tahoe.
It was a lengthy day at the Genius Bar in the Apple Store, and yes, I had two distinct appointments, unfortunately. Initially, I visited on Friday during an extra day off to have my red iPhone 7 examined for backup restoration. The Genius performed a DFU process on my iPhone 7 using his MacBook Air and Finder, aiming to remove corrupt system files that came up when the iOS 15.8.8 security update was interrupted by a disconnection or glitch and ultimately failed. That update happened hours after the iPhone completed a full backup to my Mac. 💻 We attempted to restore the backup to my older iPhone following a clean reset, but identical errors persisted with the same codes and related issues. Finder indicated a storage mismatch with my iPhone, while Apple Configurator displayed -40 as an unidentified error. He arranged a follow-up appointment for Sunday afternoon with the Lead Genius, concluding that my MBP was responsible—this situation is also unusually an exceptional case.
This backup was my sole and most recent one of my iPhone 7, containing documents and photos or videos from high school. These included engineering class project photography, nan’s pictures, several past travel images, and even the Apple infinite loop photos that never reached my iPhone XR, the device I upgraded to before my 15 Pro. As a result, roughly a quarter of my pictures failed to transfer because iCloud storage was exhausted. We made genuine efforts to recover the backup.
