Won't connect to the Internet after installing El Capitan
I upgraded my late 2009 mac mini from Yosemite to El Capitan and now I cannot get internet access I get the following error instead -
The operation couldn't be completed. Operation not permitted (NSPOSIXErrorDomain:1). Connection to wifi is good and I have rebooted both the Mac Mini and the router (BT home hub 4). Anyone got any ideas?
