My work computer is a PC, which I connect to remotely from a MacBook. MS Office has an annoying tendency to require me to sign into One Drive periodically (usually when I’m trying to do something), which requires my entering a six-digit code that is sent to my phone. My phone is usually in another room, or at least across the room. I never got around to having Velcro grafted to my chest so that it’s always with me.
I have two MacBook Pros, and they both connect to the Internet wirelessly. If I’m on the 15-inch one and I get a call or a text on the phone, an application (e.g. Messages) opens on the computer and I can answer the phone or the message from my computer without having to get up to retrieve the phone. If I’m on my 13-inch work MacBook, I don’t get a phone/message app that opens up.
Question: How can I ‘connect’ my iPhone to the 13-inch MacBook in the same way it connects to the 15-inch, and also be connected that way to both computers? (I only use one computer at a time.)
Are you using the same Apple ID on all three devices to log into Messages? And all the “You can be reached for messages at:” boxes on both Macs are all the same emails and phone numbers and all checked?
Your Apple ID should be listed near the top left. Beneath that it should say "You can be reached for messages at:”
Make sure whatever phone numbers and emails are listed on the 15 inch are also listed on 13 inch. Make sure the little checkboxes next to them are all checked.
One thing I’ve noticed - Messages try to be “smart.”
If you have the Messages up as the front-most application on one machine, you may not get a notification on another one. I’m not sure if that’s supposed to be a feature or a bug.
