How I fixed my Mac mini 2018 : Wifi and Bluetooth Issues
Apple Mac Mini 2018 : Wifi and Bluetooth issues : RANT . Not impressed with interference issues that this machine has with my usb hubs.
Since getting my new Mac mini I have nothing but problems with the Mac connecting to my wifi firstly and then connecting to my wireless bluetooth mouse. Each would not connect, or if it did would quickly drop the connection or be extremely sluggish.
THE SOLUTION
Unplug my USB hubs and then everything worked fineā¦.THIS IS NOT a solution!!
Try turning off 'Allow Handoff between this Mac and your iCloud devices'
