Now, whenever a device is trying to talk to my Mac (or vice versa, I suppose) I will see the Bluetooth icon with 3-dots through it.
That's not what it means.
The icon means that Bluetooth is enabled and at least one device is connected.
From the Apple Support Document, Using a Bluetooth mouse, keyboard or trackpad with your Mac:
If you want to see what ...
This was answered on another thread (which sadly i can't locate right now). Setting the IgnoredDevices array to contain the MAC of the BT device and cycling BT off and on again worked well for me.
sudo defaults write /Library/Preferences/com.apple.Bluetooth.plist IgnoredDevices -array-add '<MAC ADDRESS>'
The MAC address can be found in the ...
The Logitech MX Keys is a wireless keyboard that uses either Bluetooth LE (low energy) or the Logitech Unifying wireless receiver. The USB cable is for charging only.
So, excluding the USB connection from your question, this comes down to the following possibilities:
You might have interference issues with your BT (...
During writing the posting's last line I thought just disconnect from the Windows PC.
Now it works!
Reconnecting Windows again. But now don't get sound from there. I thought pairing with two devices means getting sound from both, but that's obviously not the case.
When a pair of headphones are connected to an iPhone (whether wired or wireless), it's normal for the ring to be played both on the iPhone, as well as in the connected headphones. This is by design.
If you are not hearing the ringtone play via your Bluetooth headphones, make sure they are connected (not just paired) to your iPhone when you receive the call.
I don't know why this is the case, but the USB keyboard does work on boot but only if it's in the second USB port on the back of the iMac. It's the second from the center of the mac, so the third from the outside. Every other USB port doesn't work before the Mac has booted up.
Confirmed with other USB devices as well, that port is the only functioning USB ...
I wish I knew of a way to make this problem go away completely, but the best I can give you is a workaround:
in the Bluetooth menu hit the "X" button to remove G613 from the list of connected devices
hit the connect to "Bluetooth" button on the keyboard again to make G613 discoverable.
when the keyboard shows up in the bluetooth menu hit "Connect" and punch ...
We have the same issue with a number of Mac Pro 2019 7,1 where we must disable bluetooth and all wifi/wireless. Since we have not figured out how to remove the physical chips since they are soldered on we have done this instead with a multilayered solution with fallback in case one fails. We have found with mac updates that yes everything you did can be ...
None of the above mentioned worked for me, and then I tried this:
Go to System Preferences > Network > From the side pane, Delete Bluetooth PAN using the minus sign (-) at the bottom.
Then use the Plus Sign (+) to create a new one using the drop-down menu.
The system will re-apply profile settings and you should be good to go after that.
