For some time (about a month give or take) the Network Preferences pane in System Preferences has been freezing every time I open it.
Wi-Fi works fine and I can connect using the menubar icon, but I can't change anything in the Network preference pane. System Preferences also works fine, except for the Network preference pane.
When I open the Network preferences pane, the app freezes and starts eating up system resources.
I've used the Tracking-blocker Disconnects Mac App since August, but even with the service turned off and the program not running, the Network preference pane still freezes.
System info: MacOS Sierra - 10.12.6 (16G29) MacBook Pro (Retina, 15-inch, Mid 2015) 2,5 GHz Intel Core i7 16 GB 1600 MHz DDR3 Intel Iris Pro 1536 MB
Updates: 1 | I've tried booting into Safe Mode which hasn't solved the problem. 2 | I've done a hardware test, which produced no errors and didn't solve the problem. 3 | I've done a SMC reset which hasn't solved the problem.
