Any conflicts when creating two User accounts (with different privileges) using the same Apple ID?

As promised I am adding what I have learned directly from Apple to the end of this conversation.

I contacted an Apple Senior Advisor, but he only passed on superstition... We don't recommend it, no documentation exists, we don't know what issues there may or may not be, etc.

"There wouldn’t be any actual documentation. Essentially, they’re two different accounts so they have their own settings, etc. Therefor it can use whichever Apple ID you wish to for the App Store, iTunes Store, etc."

"So yes, we would just ultimately suggest that you make use of different Apple ID accounts. Although you can attempt at using the same Apple ID, we are just unable to guarantee that everything will work properly."

"Absolutely, yes. For the use of iCloud it will allow the syncing of data simple. That I can get behind."

"I see all the concept behind wanting to use the same Apple ID though."

After one hour of chatting this is what I determined:

1. macOS allows this:
   1. You can create two user accounts with the same Apple ID as long as they don't have the same privileges, i.e. User/Admin but not Admin/Admin or User/User.
2. Apple has no idea if allowing this is detrimental or not to the user's environment.
3. Apple has not researched or documented this scenario which they explicitly allow.

As suggested, I am now off to write up a note for the black hole that is the Apple Feedback group.

@MrHoffman, Thanks for taking the time to reply.

Though, I don't really understand your response, Local Storage, NAS, I appreciate your sincere attempt to help.

I am simply asking if anyone has tried, and had any trouble with, setting up one Macintosh with two user accounts that use the same Apple ID? One being an Administrative account; the other being a User account.

I do it this way because I don't have to worry about sharing certain info between different AppleIDs. I can use the syncing feature of iCloud to keep Notes, Messages, etc the same in both accounts on my iMac/s without taking the time to share individual Notes or forward Messages. The area I am thinking there could be an issue is connecting to a server using "Connect As: Using an Apple ID" But I am not sure. If there is any evidence that this would cause an issue here then... I would have my answer.

Naturally I am asking in the forums first. This is what these forums are for. In any case, it certainly doesn't hurt to have this question asked and answered where others might find the discussion useful. I don't see the answer to my question anywhere and can't find the idea explicitly ruled out by Apple.

If there were an issue doing this I would think the OS would give a warning when signing into iCloud on the 2nd account. Something like, "This Apple ID is already in use on this machine!"

I didn't intend to insinuate there is a bug or a feature just looking for evidence one way or the other. Honestly, I am surprised there aren't others who have their Users&Groups set up this way.

If you could take the time to check whether your "com.apple.idms.appleid.prd.xxxx." id is the same on your Macs where you are signed in with the same Apple ID that would be helpful.

I should clarify that I have absolutely no issues with iCloud sharing for these two accounts. It was local networking that I was asking about.

@LACAllen. I would like to flag your response but am not able to. If you have nothing to add to the discussion don't waste your or my time with condescension! But people like you are not able to refrain. Smart A$$

The "restriction" was added to prevent people posting comments that don't answer the question and are condescending. I anticipated it because I see it so often in the Apple Community forum and therefore the request.

Try posting comments like yours on Stack Exchange and see if you every make it to "Level 7".

I don't have the answer. I have some clues.

Thanks. When I can prepare myself and have an hour to kill I will call, and wade through the process of convincing the first agent that I need a "level 2 " agent (they really don't like to give up or admit they can't help)

I think we are talking at cross purposes here. I was simply talking about data stored in iCloud for Messages and Notes, etc., not local files, being the reason I like to have the two accounts with the same Apple ID. The potential networking issue is separate from this.

I will add any information I receive from Apple to this thread.

Regarding point 1.1. It seems there are no restrictions on two user accounts with the same privileges either. You can use the same Apple ID for as many accounts as you want whether they have the same privileges or not.

I think we’re done here. Thanks.
