My iphone and imac are not in sync and my imac

[Baltimike]

keeps sending me messages to accept or decline my iphone and no matter how many times I tell it to accept, it doesn't, and just sends me a new message.

Is there an easy fix for this?

1. Are all the devices signed into you iCloud account? (n/t)

2. I *think* so...which is why it keeps asking, I think, but I am not sure

3. Accept or decline what? Air drops? Got more detail?

I have had problems when operating systems (mac and iOS) are not at a compatible level (last upgrade I attempted said download would be over a day), or if you are talking 2FA, remember that the code you get on the phone has to be tacked onto the end of the normal password you type.
