Personal Hotspot issue with IMac
I have a 2014 iMac and I'm trying to connect it to the Internet via a 15 pro personal hotspot. The smart TV, iPad all stream or access the Internet perfectly well. The iMac for some reason connects to the personal hotspot according to the network information on the iMac is connected to the Internet even connecting to the smart TV at the same time with two devices the smart TV will still stream Netflix, have disconnected all external drives rebooted several times to no avail. Cannot do anything else as don't have Wi-Fi or router.
iMac 27″, macOS 10.15
