Q: 10.10.x Bluetooth Mouse Stutter / Lag / Jittering

Hello,

same roblem.

Macbook 2010 with magic mouse BT.

I have three different magic mouses, same problem.

It seems that when I have heavy traffic on SSD samsung 850 evo the mouse get very sluggy with lags and slow movements.

Even when I use time machine with external firewire 2,5 disk the mouse sometimes get slow.

Also sometimes when I use excel or word.

Big issue with I use disk inventory scanning whole SSD  It's a mess but not continuous problems;

seems randomly slow but generally not responsive as usual.

I've also found the issue lies in being connected to the 2.4GHz instead of the 5GHz Wi-Fi signal. When I'm connected to 5GHz, everything seems to be fine. When I'm connected to 2.4GHz, there is a bit of skipping, which is super frustrating! Luckily, I can choose either signal at home.

I did have the same problem: stutter, jittering.  Mac OS X Yosemite.

Same problem if my MX Master was connected using Bluetooth or via the Unifyer dongle.

I was connected wifi at 2,4 Ghz.

I switched from channel 1 to channel 6 and the problem dispappeared.

I'm on a 12" retina MacBook using a microsoft sculpt natural desktop, with the usb dongle, and it's almost unusable.  The wireless keyboard is also lagging too! This is just crazy.

Same here... MBP13" Retina 2015 - El Capitan. Crazy!

Same issue here on 15" Macbook Pro Retina Mid 2015. Switch to 5Ghz WIFI @ home fixed the issue.. but this isn't something i can count on when I travel. Sounds to me like a hardware / signal interferance problem. Can someone on Apple support chime in and state if this issue has been identified, and if a fix is in the works?

I just switched from the 2.4 GHz wifi signal to the 5 GHz wifi signal and the mouse cursor went from jittery and choppy to smooth as ball bearings on a KY jelly covered glass table.  I can''t speak for any of the other fixes, but I just did it and it seems to have fixed it. 

Same issue here, on *some* wifi networks.

This issue appeared when I started to use a Logitech MX Master in my office. I previously used a Magic Mouse without any problems but the lag appeared as soon as I started to use the Logitech mouse.

I have access to 2.4GHz and 5GHz networks in the same location. If connected to the former type of network, the lag on the Logitech makes me want to scream. If connected to the latter, everything works like a charm. But, again, no issues at all while using a Magic Mouse, even when connected to a 2.4GHz network. So is this really an Apple issue?

how i could do That .. it's really Annoying ... or any other solutions .. ??

So does anybody have a solution to this???? -except switching my wifi to 5Ghz

I have the same issue too on my brand new rMBP15.  (A1398)  

As soon as I have to turn wifi on, my logitech MX Anywhere 2 starts to jitter and even disconnects .....

While WIFI is disabled, it works fine... So it is indeed this combination of Wifi and Bluetooth ... The mouse works with other devices perfectly...

I have exactly the same problem with my MX Anywhere 2. It seems the only two things that fix this is to a) Use 5GHz wifi b) switch off wifi and use a network connection via cable.

This is honestly driving me insane. It is most definitely not the fault of the mouse manufacturer but instead an issue with the MBP or OS X. Will there ever be a fix for this?

So I bought an USB incompatible MB12" (which has freaking softer aluminium then an iPhone 6). Forced to buy a EXPENSIVE bluetooth mouse because otherwise I cannot charge (Correct you didn't design an expensive USB-C to USB adapter with charging port...), to discover my freaking mouse stutters when using it. Useless piece of beautiful design. Instead of ignoring this topic and counting the offshore money pile, can someone from Apple finally give an official statement ons this? Would be much appreciated. Thanks in advance...

Hello,

Unfortunatly I have the same problem with logitech mx anywhere 2 and MBP2015 mouse lagging when mouse is connected over bluetooth and wifi 2.4ghz is enable... I can confirm problem exist only on MPB2015 I checked on XPS 2015 (Win 10), Asus 2012 (Win 10) and no problems mouse working fine!

I also noticed when i plug unifying stick to usb port and close lidl,  os x wont sleep...

Same issue. Is this still no fixed? When will it happen? It's really annoying as it's suppose to be bluetooth. Why would it interference with the Wifi?
