I’m a 40-year Mac user, but have recently run into a problem I can’t get out of.
I have an m4 Mac Mini and an m1pro MacBook Pro.
The Mini runs OS Sequoia and the MBP runs Sonoma.
I “like where these are” and am not interested in upgrading the OS’s at this time.
I’m a “Mac only” guy.
I don’t own an iPhone (don’t want one, or any other smartphone).
I don’t own any iOS devices.
If I’m going to do something, it’s “on the Mac”.
I don’t use iCloud at all, with one exception:
I use the “Messages” app to keep in touch with a family member (who uses her iPhone for this).
But, aside from that, I use NO iCloud services. Is “Messages” even part of iCloud?
I stay away (in most instances) from “two-factor” authentication.
I don’t need or want it.
Lately, I keep getting “locked out” of my Apple Account. When I go to use the Messages app, this will appear:
So I click “unlock account” and get this:
So I fulfill the requirements it’s asking (I’ve tried both options).
If I use email, it sends me an email with a link to click to unlock the account. I enter my password, and – things look ok. For the moment.
Sometimes I’ll get a warning that I must login to use Apple Media Services. I don’t use such services at all, not ever (unless Messages is a part of that, is it?). I just click “later” to dismiss this one.
For a while, sometimes a day, sometimes only a few hours, things may work.
But then, out-of-the-blue, I’m locked out again. Can also happen if I switch from the Mini to the MBP.
I’ve tried going to system settings, to the Apple Account, and going through every choice/option there. But that doesn’t seem to help. I unlock the account, and after a [unspecific amount of] time, I’m locked out again.
What do I have to do to prove to Apple that this… is me…?
One other question: are there any 3rd party messaging apps that will send/rcv text messages to someone else’s iPhone?
