Pairing Iphone 16 pro with my new MacBook Air.

Traditional bluetooth pairing of an iPhone with a computer or another phone or iPad is not and has never been supported. It's also completely unnecessary. Continuity, handoff, etc. do not require Bluetooth "pairing".

What are you trying to accomplish?

When you say "pair", this term usually applies to a Bluetooth connection. An iPhone does not connect to a Mac using a Bluetooth connection.

The iPhone connects using either a USB cable or via a Wi-Fi connection. In the case of Wi-Fi, both the iPhone and Mac simply connect to the same Wi-Fi network.

If you mean to say that "pair" might mean something different, please provide more detail.

Is Find My enabled on the Mac? Are your Mac and iPhone on the same Apple Account? If yes, to both, when you open Find My on your iPhone, your Mac should automatically appear in your devices list. Here is a link about how to enable Find My on a Mac --> Set up Find My on Mac - Apple Support

To your question about your former flagged email, you'll need to contact the email account provider for help with their service.

Ps: Most of your questions are less about iPhone and are more about your MacBook. I'm going to ask the forum hosts to move this thread to the MacBook forum.

mail no longer appears since from the old MacBook to the new MacBook. Thought if it paired with the iPhone it would restore that.

If you're not getting mail on your new MacBook, you need to sign in to the mail account. See this --> Add email accounts in Mail on Mac - Apple Support
