Safari Guesses Names When Filling Forms- How does it know them?

[PGB1]

Well, the problem is unsolvable. Good luck with the new machine.

I think it is solved.
Short Version: What I guessed at in #17 at the bottom- A common e-mail address in the My Card in Contacts.

While on the phone with Apple support about another problem, I asked how the new computer acquired the Calendar events & Reminder entries from the old one.

The person could not find out. I got transferred to the next level. That person never heard of this happening, was curious and tried to find out.

The person at the next level also was surprised. He had me add an event to the old computer's Calendar and Reminders. Each showed up on the new Mac. He next screen shared and dug around lots of places. Then he concluded the following:

How Apple Knew I Owned Both:
It turned out to be what I was guessing at in #17 at the bottom under "But..."
The My Card in each Contacts had a common e-mail address (a gmail address), therefore Apple decided both computers were mine & it was OK to copy the items to the new computer. I'm peaceful with Apple doing it. I wouldn't be comfortable if Google did it.

The tech guy confirmed that neither computer is syncing anything to any cloud. He didn't know what method Apple used to move the data. He was curious and said he will find out and send me a message to share with all of you.

One problem I see with that is if I have a business with, for example, ten employees and ten Macs. Should each have the Contacts list My Card with the same e-mail (for example the business e-mail), Apple will send everyone's Reminders and Calendar events to all the computers.

Later: I will add an e-mail address that is in My Card to my wife's computer's My Card and see if the events & reminders show up there.

Thank You To Each And All for helping me dig into this mystery! I very much appreciate your help and thoughts.

I turned them all off when I set up the computer- unless I missed one that I don't know about.

But it happened.

You understand what happened: Calendar & Reminders from the old computer showed up on the new one by magic.

I have not purposefully left anything out. I can't think of anything else to add to help figure this out.

Didn't you have to reinstall because of an issue? Or was that a different thread, and a different OOP?

Thank you for asking.
I did have to re-install twice, as instructed by Apple when two different problems arose. Those have been solved. (Apps not being "adopted", thus not able to be updated & Apple account not allowing an address nor a payment method, plus Apple support said it was corrupt on their end.)

Two things:

1. 10 employees at the same company will have Macs that are only work machines, i.e. not for their personal private data.
2. Yet even so, I cannot imagine that 10 employees would have everything sync'd between their Macs, so there must be a default setting (or use of Contacts) to prevent that happening; if it DID happen there would have been a huge outcry by now.

1. 10 employees at the same company will have Macs that are only work machines, i.e. not for their personal private data.

Or, possibly, each employee has her or his own projects. Thus he or she will have his or her own reminders and events associated with that project. Complete B.O.M., Submit Phase 1 Details To Client, UL Testing Report Due... Stuff like that. I would not want somebody else's events popping up on my screen.

2. Yet even so, I cannot imagine that 10 employees would have everything sync'd between their Macs, so there must be a default setting (or use of Contacts) to prevent that happening; if it DID happen there would have been a huge outcry by now.

The trigger turned out to be, according to Apple Technical Support, that the My Card in Contacts had a common e-mail address as one of the addresses. In my case, it was my businesses' address. Each also had another, but not in common. See #21 for more details.

I could see this being troublesome in a company- or even a family- if the My Cards have a common e-mail address. There must be a setting to prevent this, but the technician didn't mention one. (Note that it took him, the 3rd person, a long time to figure out why the events & reminders got sent to the new computer. New problem?)
