Did you just update your Mac to the most recent macOS version? Is your Logitech mouse not working with Catalina? Well, you are not alone. Many Mac users reported the same issue, too.

Oct 08, 2020 Apple designed the Magic Mouse to work seamlessly with the Mac. Its multitouch surface lets you perform gestures like swiping to move between pages or scroll through websites, double-tapping with one finger to zoom, double-tapping with two fingers to call up Mission Control, and more. Wired keyboard & Mouse not communicating, not able to log in. Performed PRAM & SMC resets, did not fix. Cursor stuck at the top left corner of screen, key strokes from keyboard do not register. Wired mouse will light up when plugged into front or rear USB ports, cursor does not move.

According to Mac forums, this instance is called a “MouseJack” attack. It is likely to occur among devices sold before 2016.

What Is a MouseJack Attack?

A MouseJack attack allows an attacker to break into a Logitech USB receiver that is connected to a computer. He/she can connect a device to the receiver and send any keyboard input he/she wants. Just by doing this, the attacker can install or download malware entities and wreak havoc to your PC.

Although this problem was prevalent in 2016, unfortunately, many Mac and Logitech mouse users are still affected by it.

What to Do When Your Logitech Mouse Stopped Working with Catalina?

So, have you just updated to Catalina, only to see your Logitech mouse stop working? Are you scared that you might be victimized by a MouseJack attack? Don’t worry because there are ways to resolve the problem. And the good news is that you can do that on your own. Read on below to explore some possible fixes.

Fix #1: Restart Your Mac.

Oftentimes, the problem can be fixed by simply restarting your Mac. There might be lots of active processes that your RAM might no longer be able to accommodate. As a result, problems arise.

If this is the case, restart your Mac. To do so, you have three options. First, simply press the Power button. A dialog box will then appear. From there, select Restart. The second option involves pressing the Apple key and then clicking Restart. Lastly, press the CTRL + CMD + Eject combo. It’s that easy!

Fix #2: Clean Your Mac.

If restarting your Mac does not fix the problem, the next thing you may do is clean your Mac. When we say “clean”, we’re actually referring to getting rid of any unnecessary files and documents on your machine.

To clean your Mac, you have two options: manual and automated. Sure, you may always opt for the manual path. However, it is worth noting that this method is quite risky, especially if you are not familiar with all the files saved on your Mac. Deleting an important system file may cause your Mac not to work completely.

The best option we recommend is to utilize an automated means of cleanup. For this, you can use a third-party app like Outbyte MacRepair. Download the app from Outbyte’s website and install it. Once the tool is installed, run a quick scan and let Outbyte MacRepair find all the unimportant and unwanted files on your Mac.

Fix #3: Download the Appropriate Firmware Update.

If the first two fixes did not work, you may download the appropriate firmware update from Logitech’s website. For users who have Logitech devices with unifying receivers or USB dongles, the updates automatically come with their OS update. If you are using a Logitech G900 gaming mouse, you may install a separate update from Logitech’s website.

Now, if you are uncertain whether or not the firmware update has been installed or whether your OS update came with the recent firmware, download the update manually and install it. Don’t worry because the firmware updater wizard will notify you whether your device is up to date or not.

Logitech noted that downloading the firmware update will also update Logitech wireless keyboards. Just make sure that the device is connected while running the update wizard.

Fix #4: Make Sure You Have Properly Installed the Latest MacOS Version.

Yes, you may have just updated to Catalina, but are you sure you installed the update correctly?

Here’s how to upgrade to Catalina the right way:

1. Open the Apple menu.
2. Select System Preferences.
3. Click Software Update.
4. Wait while your Mac checks for updates. If updates are detected, hit the Update Now button to begin the installation. You may also click on the More Info option to get into details about the update.
5. If the Software Update wizard tells you that your Mac is updated, then all other macOS apps should already be up to date.

Should you wish to install updates automatically in the future, repeat steps 1 to 3 and choose Automatically keep my Mac up to date. From then on, your Mac will inform you once updates are available.

Fix #5: Be Sure You Have Set the Correct Bluetooth Parameters.

You might also want to check if you have set the correct Bluetooth settings. Here’s how:

1. Go to the Apple menu.
2. Select System Preferences.
3. Choose Bluetooth.
4. Check if it is turned If it is, then proceed.
5. Navigate to the Bluetooth Preference window and select Advanced.
6. Be sure that these three options are checked:
   • Open Bluetooth Setup Assistant at startup if no keyboard is detected
   • Open Bluetooth Setup Assistant at startup if no mouse or trackpad is detected
   • Allow Bluetooth devices to wake this computer

It is worth noting that these three options will ensure that any Bluetooth-enabled device can wake your Mac and that the Bluetooth Setup Assistant will automatically launch if a Bluetooth device is not detected when connected to your Mac.

7. Hit OK.

Fix #6: Restart Your Mac Bluetooth Connection.

Here’s a simple fix you can try. Just restart your Mac Bluetooth connection and check if it resolves the problem.

To restart your Mac Bluetooth connection, follow these steps:

1. Go to the Apple menu.
2. Select System Preferences.
3. Choose Bluetooth.
4. Toggle the Bluetooth switch to Off.
5. Wait for 5 to 10 seconds before switching it On again.
