Upon updating to iOS 26.3 my iPhone 16 Pro won’t appear in MacOS 26.3 or 15.7.4. The device will charge but does not appear in the Finder or Music. DFU mode doesn’t register in Configurator. Erase and Install provided no change. Any help would be appreciated. IPadOS devices sync as normal. Is anyone else experiencing this with iOS devices?
UPDATE: After several sysdiagnose files were compiled and searched. A mysterious - Failed to get VD01 content - led me in the direction of a failed handshake. The device would charge but not sync. Several generic hubs were tested and the phone still failed to mount. However, testing on the hub of a Samsung G7 display committed to the negotiation. The phone mounts. All is well. The proper usb-hub WILL FIX this issue. TRY THEM ALL!

On you iPhone, check Settings > Privacy & Security > [scroll down to] Wired Devices. Set it to “Always Allow” for now.

That fixed the problem. Do we have any idea when the "Automatically Allow When Unlocked" is able to work again?
No one here can . We are all end users with no special access to Apple's software update plans.
On my iPhone SE 2020 running 26.3 (without issue) the "when unlocked" option is checked and seems to work fine. I always back up our phones and iPads to my computer and that works the same as it did with older OS versions.

Did not work. Both 26.3 or 15.7.4.

Congratulations on making it work! I am still in limbo. Doesn't appear in 26.3 or 15.7.4. An iPhone 6s running OS15 does. Has to be something at the device level.

That is absolutely not possible. The feature was introduced with iOS 26.

You are reading that wrong. An iPhone 6s successfully mounts in 26.3 running iOS15. I am not speaking of an evasive software feature that enabled itself on an update. Your suggestion did not work.
I’ve erased and restored twice. Still unable to sync. Still unable to use Configurator. Hoping update resolves. Sherman, please stop with the automated responses. Your fix is technically a down vote.
