Unable to use personal hotspot on MacBook Pro

I had the same issue. Turned out a setting had randomly changed on my macbook (i.e. turned off IPv6) that meant it would connect to hotspot but not be able to access the internet as the mobile firm (which required IPv6 instead of IPv4)

**Before you start, make sure your Hotpot is turned on on your iphone and your macbook is connected to it. It’ll show the Wifi symbol with an exclamation mark (!) in it.**

Then:

1. Click on the Apple logo in top left and select System Settings
2. Select Wifi in left hand menu 
3. You’ll see your iPhone hotspot name. Click on the ‘Details’ button
4. Select TCP/IP in the left hand menu
5. Make sure that Configure IPv6 is set to automatically

THANK YOU!! This worked for me! I was having the same issue…turned out IPv6 was turned to local only, and it immediately connected when I switched to automatic. Thanks again, I’m glad it works!

A shorter route is to go to System Settings the type 'TCP/IP' in the search box and select it, the follow the steps above to turn IPv6 Configuration to Automatically

That would seem to narrow the problem down to your work computer. I'd check with your IT department to see if they have any restrictions set up.

I'm really happy the fix worked for you, I'm just sorry it means you're able to work more now ;-)

Thanks for taking the time to let me know it did the job!
