Hi, on both my Macs (iMac & Macbook Air) running 10.11.4 they won't pair with the Logitech unifying software. I'm trying to pair my Performance Mouse MX mice (2, 1 on each computer) and the Logitech K750 keybord. I've updated the software to the newest download, but it simply won't pair. Do you guys have any suggestions? Thanks.

I have a Logitech M510 Mouse and after every update I have to repair my mouse. Open the Logitech Control Center in System Preferences. Make sure it is Version 3.9.3 (top right of window). If not you can download here: http://support.logitech.com/en_us/downloads

Click on Open Unifying Software button then Advanced.
Select the device (not the top but the indented device.
Select Un-pair
Now you should be able to pair the device.

Move the USB connector as close as possible to the mouse.

You might also have corrupt plist files. In your User's Library/Preferences, delete all the com.Logitech....plist files.
Log out.
Empty the Trash
Now try to pair the device.

com.Logitech.Control Center.Assignments.registry
com.Logitech.Control Center.Daemon.plist
com.Logitech.Control Center.Device Manager.plist
com.Logitech.Control Center.Device Settings.registry

Thank you! Looks like I was running an old Logitech Control Center version. I was wrong in that it wouldn't pair, it would show up in advanced options, but wouldn't finish in the regular setup and not show to configure it. After running the correct version, it would finish. Still sucks that you have to repair after each update, hopefully Logitech will fix it.

My Post from another thread:

I run my Logitech Performance MX mouse on a metal extension just to the right of my keyboard on my computer stand. The Logitech Unifying receiver is mounted to a USB extension cable and I have the receiver taped to the underside of the metal extension, right under the mouse and pad. I find that otherwise I have a lot of interference and get very sluggish performance.
