iMac cannot connect to internet after Sequoia Update

Hello ,

Was facing the same issue & tried all troubleshooting steps including reinstalling of OS

Finally deleted the Little Snitch application VPN connection list

System settings -> Network ->

” below WiFi delete all VPN even though it’s off “ Erase VPN

Now everything worked normally

Was exactly the same problem. I was trying to fix it around 3 hours. My friend helped me. Go to settings->network, click on wifi block by right mouse click to see context menu and choose ‘delete Service’, after click on ‘…’->add service->wifi and boom - everything is working

This still doesn't work for me. I've checked, I don't have ESET in my MacBook. My trash is also clean. I'm facing same issue even now.

I clicked link for "check for related login items" and did what it said and removed the VPN logins and eset stuff and seems to have worked now.

However now I'm not sure if i reinstall eset or the VPN software it'll all malfunction again!

OMG I LOVE YOU xoxoxoxo thank you soooooo much!

That's what I thought, no I have no extras installed ESET etc, and this is only

happening with Sequoia not to any of my other macs running Sonoma, and

the mac that has the issues was also fine with Sonoma, it could be a

Safari issue as it seems firefox is working at the moment, but both

browsers stopped working earlier today.

I think depending on our exact devices/circumstances, solutions can be a bit different for each of us. I was experiencing the same issue, where my WiFi showed “Connected” but I could not open any webpages, receive iMessages, etc. What fixed things for me was going to “Settings”>”Network”>”VPN & Filters” and setting the status of all filters/proxies from “Enabled” to “Disabled”. (I had an old VPN software installed that was listed as “Enabled” even though I haven’t used it in years.) Finally, I restarted my Mac and everything began working again.

Do you have any antivirus, cleanup apps or VPNs installed if so uninstall them as they can cause loads of issues. Restart in safe mode followed by a restart and see if the internet works.

Turning to fixed, fixed my issue

Thanks for this reply, I had the same problem. Removed ESET filters and all good. Thanks.

Tried all that and did not work. Unable to get Mac to start in safe mode for some reason. Not able to do that. Have deleted eset and also a VPN software and emptied trash. Also cleared filters for the network. Help

Ah, so the issue is actually ESET Cybersecurity anti-virus app that is not compatible with macOS Sequoia ... at least, not until they provide an update. Good troubleshooting!

One thing to take into consideration going forward. Your Mac does NOT need a third-party anti-virus software. macOS already has numerous security features built-in and I suggest that you refrain from using one in the future.

Glad you got it working
