Why does the Apple Support Community site lists my MacOS as Ventura even after updating to Sonoma?

Welcome!

What shows in those automated equipment listings is supposed to be pulled from devices you have associated with your Apple ID. For me it works about half the time.

If you have more than one Apple ID, that trips up the system. If you have no devices listed, that trips up the system. And sometimes the system just trips itself. That has been a problem for a long time.

We are neither Apple nor forum moderators, but end users like you. We cannot fix this. We understand the mods are aware of this issue.

The sure workaround in the meantime is to include device info in the body of a question. Example:

"I have a Mid-2015 15-inch MacBook pro running macOS 12.7 and it started to....."

No confusion that way and you are assured that helpers here properly identify your device so you get answers appropriate to your Apple product. And we don't have to guess. We are not good at guessing!

Probably just a bug in the Community software or linkage to your device list.

You can always add your actual version in your post text if the shown is wrong.

Not sure why this would hold you hostage to anything in any way.

Perhaps you are being a bit melodramatic.

Reading your other post, sounds like a hardware issue with your Mac. You may wan to ship the Mac in to service for diagnostics and possible repair.

I am concerned viz a viz several problems mentioned in my other responses to comments in this thread, about digital usurpation.

Then that is beyond our ability to address here. We as your fellow end users have no control over Apple policies nor the moderation of these forums, and both topics are subjects on the "not permitted" items in the Terms of Use we all signed.

Babowa has given you the link to the document where the moderators' email contact is shown. Please use it instead of open forums.

I am not concerned about responders in this forum having my correct information.

If we do not, there is no way to help constructively. We do not have access to Apple's database. The only info we have is what you tell us.

I listed the necessary machine identifiers in my original question.

You said you had a Mac running Sonoma.
