After all you can reinstall kaspersky, it will run without any issues. Btw remember to give it background working permission, otherwise it couldn’t have access to read your disk even if you allowed.
Hi! True that, downloading an app would be a problem. Have you tried other steps from the video like resetting the DNS server or resetting Mac Network settings?
So what worked for me is I went to network I had little snitch what I did was removed it w/ the minus sign and restarted my internet was connected after update but was going in and out couldn’t connect to FaceTime or iMessage but that fixed it at first I disabled it but then I was like I’ll just remove it
Maybe you should turn off the firewall setting and any vpn connection too, cause it works for me. Lastly, don't forget to update to MacOS Ventura 13.01 it already release right now. I Hope this step can help your problem.
