2nd Gen iPad Pro not showing in Finder, not showing "Trust this Computer" message. Still beeps and Charges.

My Mac mini M4 running macOS Tahoe 26.7.1 will not recognize my second-generation iPad Pro running iPadOS 17.7.11 over USB-C to Lightning. The iPad charges and beeps, but it never appears in Finder or System Information's USB Device Tree, and no Trust This Computer prompt appears.

The iPad Pro connects successfully to my M1 MacBook Pro. My iPhone 13 Pro Max connects successfully to the Mac mini using the same cable. I've tested multiple cables and every USB-C port, tried Safe Mode, performed a full power cycle, reset Location & Privacy, and upgraded macOS from Sequoia to Tahoe. None resolved the issue.

The Mac's USB logs show repeated failed to create device, failed to address device, disabling port, and persistent enumeration failures messages when the iPad is connected.


I'm at wits end.

Hi there


Please try this

  • Instead of plugging USB-C-to-Lightning directly into the M4 Mac mini's native USB-C/Thunderbolt 4 ports, insert a basic Apple USB-C-to-USB-A adapter or a powered USB-A/C hub in between.

:This forces the M4 host controller to route through an xHCI protocol translator/hub layer rather than direct USB4/Type-C direct-attach power delivery negotiation, which often bypasses the strict enumeration freeze seen in Tahoe.

Nick,


Out of town right now, but I will give that a try when we get home. Thanks for suggesting.
