Sonoma and Personal Hotspot issue (and workaround)

[macguru212]

I have an internet outage (thanks Cox!) - so I was forced to use Personal Hotspot from my iPhone 13(17.3), this is when I discovered an issue with my MacStudio running Sonoma (14.3)

The MacStudio would connect to the iPhone, but no internet was available. I tried other devices: iPad(17.3) and an old iMac without any issues of any kind using the internet through Personal Hotspot.

Turns out there is a bug with DNS in Sonoma (or at least there appears to be)

Workaround is to remove DNS Servers from any you have listed. (System Settings/Network/Wifi/Details/DNS)

Internet works after this.

Of course you'll have to re-enter any DNS entries for Wifi, so maybe write them down first.

cheers

The DNS servers that have been removed, are they local IP addresses or public ones?

My ISP's IPs. Interesting thought tho - I wonder if public IPs would make a difference. I'll test tomorrow.
thanks!

I had to test this now lol

but yes, public IPs have no issue with Personal Hotspot. Makes sense now, though I didn't have to do this DNS switch with my iMac, at least I understand the problem and can get around. thanks again!
