Mojave 10.14.5 "Cannot connect to internet"

Did this new update do something to my connection? My other devices are fine. Only my iMac is impacted. Connected via wifi and ethernet. TIA.


iMac 27", macOS 10.14

So that tells me you are connected to the network but you're not getting out. One other thing you can try is flushing your DNS.


Open terminal and type this command: sudo killall -HUP mDNSResponder


It will prompt you for a password, enter your computer password and hit enter (please note the cursor will not move)


Try the internet in a couple minutes. If no internet you may have the issue I'm running into.

First of all let's have you try to ping your router (assuming you are at home), the easiest way to find it is to go into your network settings under system preferences. Click advanced and the numbers after "Router" are what you want. Most of the time it's 192.168.0.1 or 192.168.1.1.


Once you know what it is, open terminal and type the following: ping (router address) (example: ping 192.168.1.1 and hit enter.

Hi all to give you an update:




I had an identical MacBook Pro that was not having the issue so I decided to rule out bad hardware and swapped the hard drives. The problem followed the hard drive so I was able to rule out hardware.




I decided to wipe the new hard drive in the users computer and copy documents over. The install of my USB stick was 10.14.3. So far the machine is working properly but it’s not ideal for me to be rolling back with doing clean installs for the other users.




I upgraded my machine to 10.14.6 beta and so far it seems to be doing alright.




I’m pretty convinced this is an issue with 10.14.5.
