I’ve had my Logitech MX Master 3S have its low res moments from time to time, but lately, it has gotten way worse. After trying out various solutions, I found the following works perfectly well. I’ll share the solution first and then explain what it is.
Solution
First, run the following in your terminal –
sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt HybridReboot your computer after running the above command. This should fix the issue with the mouse pointer lag.
If you want to revert your setting back to original, run the following command in your terminal –
sudo defaults delete /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmtCredit to /u/stankuus for coming up with it.
Explanation
I wanted to get a better understanding of what it does and Bard helped me with that. Here’s what Bard had to say about the command –
The command
sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt Hybridis used to change the Bluetooth coexistence mode on a Mac computer. Bluetooth coexistence mode is a setting that determines how Bluetooth and Wi-Fi devices share the 2.4 GHz radio frequency band. There are three possible coexistence modes:
- Performance: This mode prioritizes Bluetooth performance, which can sometimes cause interference with Wi-Fi.
- Balanced: This mode tries to balance the performance of Bluetooth and Wi-Fi.
- Hybrid: This mode prioritizes Wi-Fi performance, which can sometimes cause a slight decrease in Bluetooth performance.
The bluetoothCoexMgmt Hybrid setting tells the computer to use the Hybrid coexistence mode. This mode is generally recommended for most users, as it provides a good balance of Bluetooth and Wi-Fi performance. However, if you are experiencing Wi-Fi interference, you may want to try changing the coexistence mode to Balanced or Performance.
Conclusion
I will keep an eye out to see if there’s any performance hit on my Wifi experience. So, far I’ve been using it for a couple of days and haven’t had any issues.
Update 12/07/2023: 10 days later, this seems to be working perfectly well.
