Slow M1 iMac
Barely 90 mbps on M1 iMac. Internet tech left awhile ago, confirmed receiving 300+ mbps; showed me on his meter and I am getting +400 on my iPhone. Reading through the posts noticed one about usb-c adapters, which I'm using for back up disc, keyboard, and ethernet adapter (Belkin). I thought, what the ****. Unplugged the adapter and re-ran SpeedTest..... 360 mbps. Apparently that's what happens when you don't have enough ports on the ***** computer.
iMac 24″, macOS 13.4
