I’ve got a customer with an iMac (waiting on screenshot of About this Mac)Mac OS 10.13 and it’s approx 4-5 years old
It can’t ping both BT routers either wired or wireless. Other devices work fine on both their routers
It’s had a fresh install of Mac OS by restarting and holding down Cmd & R
It obtains an IP address and have tried using Google for DNS
Does this sound like a hardware failure?
They have not tried clearing the PRAM yet
Basic but perhaps reboot the routers as that occasionally resolves this issue.
Yes I’ve tried rebooting the Routers thanks that didn’t work And I should’ve mentioned that in my original post
I’ve accidentally fixed the problem by removing McAfee Total Security as it was crashing when I tried to open it earlier
Well done... I’ve avoided McAfee products like the plague on windows and certainly Mac systems. More trouble than it’s worth, and true pain to update definitions... I do use Bitdefender free version on my Macs (Macbook Pro and Mac Mini) both runningel capitan.
