Universal Control warning

Posted: 15-Jun-2022 | 9:36PM · 2 Replies ·

I've been getting consistent Norton warnings on my MacBook Pro starting last week that reads: The computer "xxxx" is attempting to access Universal Control on your computer. Do you want to allow this connection?  (I'm running macOS Monterey 12.4, M1 chip.)

I suspect this may have something to do with my Apple systems attempting to communicate with each other, but I'm not sure. Apple also sent through OS updates on pretty much all their devices recently, so it could be related.  It's ominous enough sounding that I refuse to grant access, selecting block each time it appears, but this is not a long-term solution as I'm constantly blocking the request a dozen times a day. Nothing on the Norton forums or Apple forums address this.  Any ideas what's happening here?

I have an M1 Max Macbook Pro running macOS Monterey 12.4, and have had similar warnings. I believe it is my iPAD, which uses Apple Wireless Direct Link, to connect to my MacBook Pro. The Norton warnings report: "The computer "XXXX" is
attempting to access Universal Control on your computer. Do you want to allow this connection?", where XXXX is an IPV6 address.

If I go into the terminal app and enter "ndp -a", then I can see a list of devices on my local network in the "Neighbor" column (some will be IPV6) and their corresponding mac addresses (the "LinkLayer Address" column). In the "Netif" column, which shows the Network Interface, I can see that the computer in question that is attempting to access Universal Control uses awdl0 - Apple Wireless Direct Link. Of course, the mac address listed in the LinkLayer Address" column won't correspond to the actual mac address of any of my Apple devices because it is randomized. 

Going forward, I will click allow for this connection.
