1 Short story, we have had 3 techs and then an entire crew from our cable internet provider to verify our internet speeds on ethernet. The choke point in upload speed is our computer. They have tested every point along the line and the slow down only happens on our iMac and Mac Pro desktop. They are running different macOS versions (High Sierra and Mojave). The line says 30mbps up and the computers can only do 3-5mbps up. How could the computer be throttling? networking macos mac share | improve this question edited Jan 16 at 18:44 Spiff 77.8k 10 118 163 ...
