Cannot connect to the internet
My iMac running OS Ventura will not connect to the internet. The blue bar loads a short way and then just stops. Mail works fine as does my phone, iPad and MacBook Pro. I was using a CyberGhost VPN, but I’ve deleted it on this machine. I’ve also deleted Adguard. I tried connecting with Safari and Firefox with the same result. I’ve even reinstalled the OS, but it’s exactly the same. Any ideas anyone?
