Q1: Yes, I used Migration Assistant to move files to this Mac mini (Apple Silicon). I believe I only migrated files, not the full user account. My previous Mac likely had uid 502 assigned to my user account, which may have carried over to the system directories on this new Mac. Q2: There is only one user account on this Mac. Q3: No, this is a personal Mac, not managed by any organization. No endpoint security software installed. Q4: I don’t believe so. This Mac mini is relatively new and I don’t recall ever disabling SIP. Please let me know if there’s any additional diagnostic information I can provide, or if there’s a recommended fix for the uid mismatch.

Thanks, Ed. I checked the code-level support request page and pushed Start Your Request, but my account currently can’t access it. "Your account can’t access this page. There may be certain requirements to view this content. If you’re a member of a developer program, make sure your Account Holder has agreed the latest license agreement." It may be related to my current Apple Developer Program membership status, which I haven’t completed yet, but I’m not certain. For now, I’ll continue through the existing Feedback report and the forums route, and I’ll follow up here if I receive any additional findings.

Thanks, Ed. I tried the code-level support request link in your post, but it currently leads to a “The page you’re looking for can’t be found” page on my side. I’m signed in to my Apple Developer account. Is there another direct link I should use to open the request?

Thanks, Ed. My Feedback report number is: FB22183081

Thanks for sharing — that’s very helpful. I’m seeing a similar “unavailable” state on my side as well, even though the device is detected at lower levels (Finder sees it, trust is established on the device, and Developer Mode is enabled). I’ve already updated my Feedback report with Core Device logs from both macOS and iOS. This makes me think it may not be isolated to a single machine-specific setup.

Thanks. I’ll collect the Core Device logs from both macOS and iOS, file a Feedback Assistant report with the attached logs, and post the FB number here once submitted.
