OCLP Mac OS Post-Migration Wifi Switching On & Off Issue - Turn Off Internet Sharing

Hey folks, hope everyone is doing well :)

Just thought I'd share a solution I found for an issue that I've been having trying to migrate my Mac OS Installation from my old MBP to my newer MBP where once the migration was complete, I was having issues with my Wifi continually switching on and off every ~10 seconds or so. In the end what it seemed to be was Internet Sharing was turning itself on and off continually.

To turn it off (I didn't even know it was in the System Settings Menu at all as I'd never needed it) head to System Settings > General > Sharing > Internet Sharing, and the option is there. In my case I not only had to turn it off, but actually change the Sharing option from "Wi-Fi" to anything else, in my case being Thunderbolt Bridge (as I haven't got one). Only then did this solve my issue.

A couple of other notes for anyone in a similar boat - I found this occurred for me regardless of whether I took a straight clone of my old drive (using dd or the Disk Utility Imaging & Restore Functions), and on Sonoma the Wifi Sharing was somewhat clear as in the Wi-Fi drop down clearly showed "Wi-Fi Sharing" as it turned on and off. On Sequoia however, this was a lot less clear as in the drop down Wi-Fi Menu, it only shows a random string of characters when it goes into Wi-Fi Sharing mode, making it unclear of what's actually causing the issue. The only giveaway is that the network it connects to is the computer name. I haven't been able to verify if this is exclusively an OCLP issue due to the age of my Macs, but given I haven't been able to find anyone else with the same issue online, I'm presuming it is?

But regardless, hopefully this points someone in the right direction if they're having issues, and hopefully it is of use to someone! :)
