- Mac-Mini (late 2014) 2.6GHz Intel Core 5, 16GB RAM 1600MH DDR3, 1TB (SATA)
After many weeks of being pestered by Apple's notifications, I upgraded my mid 2014 MacMini from High Sierra to Mojave.
(A 2014 model bought new from Apple in 2017 with Sierra installed.)
All seemed OK for 2 days, then it won't connect to FiOS router's LAN and performance is terribly slow.
Router is connected with ethernet cable (I've tried several cables with no difference).
I've powered down and rebooted the router and MacMini several times.
There are 6 other Apple devices, 3 smart TVs, a TiVO, and VOIP telephones on the same LAN and they all work OK.
The fan shaped Wi-Fi icon in the menu bar is grey with a "?" inside. Clicking it produces "Wi-Fi: No Hardware Installed".
The router's indicator light for the MacMini's ethernet cable is lighted, showing that the the connection is recognized.
The Mojave Network Control Panel shows both WiFi and Ethernet as 'Off' and they won't turn to 'On'. Sometimes trying to turn ethernet on produces "Ethernet connected but Mac has no IP Address."
Simultaneously, performance has tanked. The reboot process produces a message saying "You turned off your Mac because of a problem. (I never did) Do you wish to to reopen the same windows as before? If you do nothing your Mac will restart in 59 seconds." Then the countdown counter takes 15 seconds to countdown each second!
I suspect this is the result of multiple failed attempts to access the network while trying to do anything. Analysis and trials are very frustrating.
Activity monitor's 4 CPU bars continuously show only 1 light in 2 bars with intermittent bursts of 'flat-out max' activity. No activity I recognize shows near the top of '%Use' activity column.
Your thoughts, please.
