Earlier quoted context omitted.
If you have an Apple account, why are you even using Beeper? I guess it might have some advantages for convenience (multiplexing chat apps), but is that the main selling point right now? I'd imagine the target market is Android users who want to talk to people on Apple Messages. So they can just create a new Apple account, right? (Isn't that kinda hard anyway, though? You need to tie it to billing, etc.) And if that…
I sit in front of my work laptop which is signed into my work apple account. My iPhone is signed into my personal Apple account. I cannot iMessage from the keyboard because they won't play together. I've been using Cloud Beeper since early summer, and it makes the two apple systems play nice together. I also have a Windows machine signed in to it, but that's a nice to have.
Btw, this is mostly unrelated, but do you work for a large company? I'd assume most security teams would have a problem with a setup like this.
