Just updated to Catalina and my M325 Logitech mouse stopped working immediately. This mouse works with a USB unifying dongle. The Logitech keyboard also running off the same dongle has kept working, but the mouse does not. Reading earlier blogs from Catalina beta, I see this issue was raised. Is there a fix? Is Apple aware of this?
MacBook Air
You can make it work
You need Logitech Control Center
Software Version: 3.9.9
You can download it here:
https://support.logi.com/hc/en-gb/articles/360025297833
Make sure it is installed correctly as described here:
-If you didn't install the updated LCC before updating to Catalina, you will probably need to restart your computer in recovery mode, to restart again to install it correctly.
Launch Terminal from /Applications/Utilities folder
Run the following command :
kextstat | grep -i Logi
105 1 0xffffff7f8252b000 0x47000 0x47000 com.Logitech.ControlCenter.HIDDriver (3.9.9) BB513FDB-C9C7-3A6F-AD71-58CDD322B095 <104 76 49 25 6 5 3>
106 0 0xffffff7f82582000 0x16000 0x16000 com.Logitech.Unifying.HIDDriver (1.3.9) 4E15EC6B-3BB3-3644-B366-F5EFB857C2BB <105 104 49 25 6 5 3>
If the “com.Logitech.Unifying.HIDDriver” is any version other than 1.3.9, then the new driver was not properly loaded by macOS Catalina. To fix this issue, please try the following steps:
1. Start your system in Recovery Mode:
- Restart your computer (From the menu bar, click on the Apple logo and select Restart)
- Hold the "Command" and "R" keys until the Apple logo appears.
2. You should see "macOS Utilities" screen, if not, repeat step (1).
Close this window using the red button on the top left
4. Click on "Choose Startup Disk..."
Then select "Restart.."
Lastly, select "Restart" again - you may see a spinning icon for a few minutes before rebooting.-
Also make sure the updated LCC has monitoring access as described here:

I have the same mouse and it worked after following these steps.
Logitech has recognized this issue and is working with Apple.
This issue was not caused by Apple. It was an incompatibility with Logitechs prior LCC version and Catalina.
Apple is not responsible for making sure that all 3rd party products work with their OS.

No update has been issued by Logitech on either their software or their firmware as of today.
If you are running the original Catalina installation without the update (I don't have time to update yet), you can boot into recovery mode and clear the kernel cache.
kextcache -i "/Volumes/<VolumeName>"
I run into this with the DisplayLink driver for my Mac. The instructions are here; just ignore removing/installing the displaylink part.
Updated to Catalina and all available patches to date.
Even after updating the Logitech software to the latest Logitech Control Center version for my devices (v3.9.9), and rebooting my machine, I see a dialog box with the following 'blocking' message:
System policy is blocking Logitech system extensions from loading, which may result in some Logitech devices not working properly.
You can enable Logitech system extensions from the Security & Privacy Preferences pane. You may need to restart your Mac for the changes to take effect.
Here is that dialog box:
When I touch on the blue button 'Open Security & Privacy', my pointer is still alive but no existing windows respond to mouseDown events. If, instead, I open the Security and Preferences pane separately, there is no Logitech system extension listed in any of the panes for any of the system elements. There is nothing to 'enable'.
How do I clear this block?
The current work-around is to hide this window by dragging it to the bottom of the screen, and avoiding clicking on either button. Obviously not a solution.
This is the first of five systems we own to be converted to Catalina and we are likely to have this issue with allow them.
Thank you!

This morning I was prompted to install a newer update (i.e. one AFTER Catalina). After the install and restart my Logitech devices now work on my Mac.
What is the name of the file you downloaded? Please share the name, so we can go on the hunt for it, perhaps asking Logitech.
I happened on this and noticed my keyboard starting working after rebuilding the kernel cache.
I got tired of dealing with this so just purchased an Apple Magic Keyboard which I'm sure Apple will be pleased about.
