My new iMac won't connect to the internet
New iMac (year 2017), won't connect to the internet although everything about TCP seems to be all-right.
- The iMac is totally new, just unpacked. Green light on TCP connection.
- My old iMac connects fine through the same TCP cable.
- If I try to get an new Apple Id, it is rejected.
- If I try to run software update it is rejected.
- Safari can't connect to anything.
