Logitech MX Master 3S Bluetooth Issue / Lagging / Delay

Had same issue with Logitech MX 3s on bluetooth connection.

I used these devices over bluetooth:

• Logitech MX master 3s
• AirPods Pro 2
• Bose QC 45
• Nuphy Air75 Keyboard

Steps I tried:

• Tried to reinstall LogiOptions+ - no luck
• Removed all permissions, still lag
• Restarted bluetooth daemon, still lag

Finally I removed all bluetooth devices that were listen in bluetooth settings but not connected: Lag has gone!

Strange but it worked 🤷‍♂️

I disconnected bluetooth and am using the USB receiver. Problem still exists. It makes me think its not the mouse in this case. Maybe some logitec software running in the background thats screwing things up?

LAG SOLVED

I've had really bad lag/delay using my MX Master 3S for Mac on my iMac Pro running Ventura 13.1. One post said it was when they opened System Preferences, then their mouse would lag. For me, it would lag/jump any time my iMac was "thinking". Any window opened, closed, file saved, closed, application opened, closed, etc. I read this post where people solved it by reducing the number of Bluetooth devices, suspecting an issue with Bluetooth bandwidth.

In my case it was much more specific.

There were 4 BT devices in my BT preferences: 1) Magic Keyboard w/ Numeric Keypad, 2) Magic Trackpad 2, 3) MX Master 3S M (my current mouse), and 4) MX Master 3S, a previous mouse that I replaced but never removed from BT. Only one device was connected, my current 3S M.

I removed the previous 3S mouse from my BT list, and even though it was not connected (and is not even present in this building), THAT ELIMINATED THE LAG COMPLETELY.

Somehow, the other mouse still being on my BT list caused a communication issue with the mouse I've been using. I can't say if that sounds more like an Apple or Logitech issue, but it's certainly a stupid issue. But it has solved my lag issue. No reboot. No sudo terminal commands. No other change needed. Instantly gone, smooth mouse movements. I tested it by opening and closing System Preferences, various Office 365 apps, browsers, etc. The lag is gone.

Here's hoping it doesn't return.

Same problem here.

• 1 Apple Magic Keyboard
• 1 Logitech MX Master 3s
• 1 Apple AirPods

As suggested by @ayrton273, I tried:

sudo pkill bluetoothd

This solves the problem (maybe not indefinitely).

Really looking forward to a solution to this super annoying bug!

Had the same issue, solved from a redditor's post which says to basically create a file named com.apple.airport.bt.plist in the /Library/Preferences path using the command below:

sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt Hybrid

Is there any ticket or post to track this issue, perhaps on the logitech community?

This doesn't work. How can something so fundamental like bluetooth audio be ignored by apple. I'm using a Macbook pro and airpod pros. This kind of thing should not happen, or should be fixed faster. Ugh.

Same issue here

Apple Magic Keyboard

Logitech MX Master 3s for Mac / MX Anywhere 3

Bose Quiet Comfort III

Killing bluetoothd helps for a short time but after some time mouse cursos lags and music stops for half second which is annoying.

This is extremely frustrating. I've been trying to solve this for almost 2 years. And I really don't think it has anything to do with the Bluetooth. I think macOS in the back blocks the mouse functionality periodically it's not consistent I could have a whole day sometimes no issues and then all the sudden it starts getting laggy. What is so incredible is that there is really no other option than this mouse if you are doing anything advance on macbook pro.

Same problem here

Problem solved when I connect other devices through wire.

But same problem occurred as long as I connect more than one devices(not apple's product) through bluetooth.

• 1 keychron keyboard
• 1 logitech MX master 3s
• 1 B&W PX7

Same here!

• Logitech G915 keyboard
• Logitech MX Master 3S (not for Mac)

Im using in my 2012 MacBook Pro with Mac OS Catalina; It’s so annoying, but after I open the Logitech Software the problem gone but after I turn on the computer the problem come again!

some one know any definitely solution?

Thanks!

So if writing terminal commands isn't your thing & you're tired of rebooting your mouse, try this.

After having read 3 other similar threads in Reddit & going over all comments & solutions, what worked best for me has been the procedure in the article: https://www.howtoisolve.com/logitech-options-not-working-on-mac/

I have been having the issue on my intel macbook pro & now on my m1 max (both on Ventura) as well despite having followed the Logitech representative's recommendations in the below comments (which were outright irrelevant).

Bottom line:

1. update the logi+ app
2. make sure all logi permissions are ok (input monitoring, accessibility & login items)
3. reboot your computer

This worked for me despite having Airpods Pro & a Keychron K3 connected over bluetooth. The jitter lag has not resumed either, so keeping my fingers crossed!

SOLVED

I also had the same issue with MX Master 3S on M1 MacBook Air (Sonoma 14.1.1).

No other bluetooth devices were actively connected, not just to this computer, even in THE ENTIRE HOUSE.

Tried the following:

• forgot every other bluetooth devices (AirPods, Magic Mouse, Magic Keyboard, JBL Go3)
• executed:

sudo pkill bluetoothd

• restarted the OS
• reconnected the mouse

After these steps the issue is gone and hopefully won't return.
