(macOS High Sierra)
My iMac connects to the internet but it can't load anything involving an internet connection. At first I thought it was something wrong with the DNS so I changed it from 1.1.1.1 to my ISP given DNS but that didn't do anything. (I also tried 8.8.8.8) Next, I decided to renew my DHCP lease but that also did nothing. As a last resort I decided to spoof my mac address but that also failed.
I assumed something was wrong with my router but that's not the case because I tried connecting to my personal hotspot and I still got the same error. I am so confused and any help would be appreciated!
