Magic mouse 2 mouse lag on macbook pro 16" 2020

I'm having issues with my magic mouse lagging to the point of not being viable to work with. Anyone else have these issues. I've just updated to Catalina 10.15.7 - wasn't doing it before that.


Help!

MacBook Pro 16″, macOS 10.15

Hello everyone, I use a late 2016 touchbar MAcbook Pro with highest specs and I think I solved the issue. At least found out the reason. This Magic Mouse 2 lag thing happens due to interference with USB-C external peripherals somehow.


I am using a Dell U2518D as an external monitor and connected with USBC to DisplayPort Cable. I changed the USB-C port from right to the left side and lag ended. You can try different combinations if you have any external peripherals. It looks like, in my setup, right side of the USB-C ports on my mac does this interference. It hapened with a USB-C multi connection HUB as well.


Please try and share your findings. I really don't want to give up on my Magic Mouse 2 as I am used to it with many gestures.

Update: Bought a Logitech mouse, programmed the buttons to be mac-friendly and I've had zero issues. Note: I'm using the Logitech USB Bluetooth dongle and NOT the Mac Mini's Bluetooth. I have determined, after reading and trying all the troubleshoots, the Bluetooth adapter in the Mac Mini 2018 is complete trash. I would love to upgrade to the new M1 Mac Mini buuuut it doesn't have upgradeable memory so I'm stuck with this workaround for now. This may be the last Mac I ever buy...I hope this helps!

Hi, I'm not sure if you found a solution. I starting having terrible lagging issues, along with shaky movement, with my Mighty Mouse 2. It was working perfectly one day, I charged it, and then it suddenly became an infuriating experience. I was very close to taking it to the Genius bar.

I did all the things you find out there, including:

Cleaning it

Removing bluetooth preferences files

SMC reset

Factory reset

Resetting bluetooth module on Mac

etc. etc. etc.


None worked.

I suspected Wifi interference, but I don't have many options in terms of moving my router and computer. I thought that maybe there was bluetooth signal interference, maybe?


I'm only typing this here because I found the solution (and others can try it if they are searching for help):


I have two external monitors for my Macbook Air. The way it handled the dual monitors after the update to Big Sur changed, so the mouse issue may be more related to the OS.


I opened the Display preferences and set all my monitors to "Scaled". This fixed the issue immediately.


System Preferences > Displays > (Change from "Default for display" to "Scaled")


Does that I mean this is a graphics problem/lag? I have no idea. My mouse now tracks perfectly, you have no idea how happy I am now. This problem was creating constant stress and I am so relieved it is solved.

I'm having this problem too, on my Mac Mini 2018. I've been experiencing this issue for about a month, which lines up pretty well with the update to Catalina 10.15.7.


Troubleshooting tips led me to disabling and enabling bluetooth, checking the mouse sensor, removing USB-C accessories, etc. with no luck. Mouse works fine when I pair it to other devices like my iPad Pro.
