Yosemite cursor lag

[grossmusic]

temporary workaround

No solutions or fixes, but I did find a workaround. I created a new user & the issue does not occur there at all. Unfortunately, due to lack of disk space, I must use a thumb drive to move files to the new user, work on them, then return to my main account until I have time to do major backups & resets.

If you have enough space on your hard drive to do so, just create a new user, move all your files to it & start afresh.

Just to follow up I had two 2014 13" rMBP's both with Yosemite firmware (black screen bootup) that I rolled back to Mavericks, both would stutter recovering from idling the cursor.

The 2015 13", on yosemite firmware ofc, is working on yosemite without stutter or a delay.

its either that firmware not playing nice with mavericks or the 2014 model just having a weird quirk. never tried 2014 on yosemite so couldn't say, its possible that would resolve it.

I am on Mavericks with the Yosemite firmware on a 2012 15" rMBP and have no lag or stutter whatsoever. Had on Yosemite.

Before 10.10.3 I only had randomly disconnects from bluetooth keyboard.

After I started using the 10.10.3 betas/pb the issue spread to Magic Mouse and Trackpad and now with 10.10.3 final out it still occurs Awful lag which makes the computer unusable I've submitted 2 bug reports for this but still no reply.

I suggest you all submit bug reports https://radar.apple.com to make pressure on them to fix this

On a side note the last time this happened I glanced at my iPhone 5 (with bluetooth on) and noticed the bluetooth symbol flickering between full white and grey like it was reconnecting to something. Check if this also happens on your side.

It's happening again, I checked in console and I have some bluetooth errors:
13/04/15 21:33:37,000 kernel[0]: **** [IOBluetoothHCIController][EnqueuePacket] -- commandSleep(&mNumberOfPacketsInQueue) failed -- counter = 1 ****
13/04/15 21:33:39,000 kernel[0]: **** [IOBluetoothHCIController][EnqueuePacket] -- commandSleep(&mNumberOfPacketsInQueue) failed -- counter = 1 ****

13/04/15 21:33:41,000 kernel[0]: **** [IOBluetoothHCIController][EnqueuePacket] -- commandSleep(&mNumberOfPacketsInQueue) failed -- counter = 1 ****

Fix the god damm bugs Apple, screw your amazing new features...

I have some very bizarre findings.

I have two mice (both apple magic mouse on bluetooth), one at home and one at my office. In both environments, I have have pretty much the exact same equipment setup (same external monitor, external keyboard, etc.)

When I'm at home, I NEVER experience this issue. When I'm at work, I ALWAYS experience this issue.

So in trying to isolate the issue, I of course swapped the mice, hoping that the home mouse would also work fine at work and that it had something to do with that specific mouse. This was not the case! The mouse that worked 100% of the time at home now does not work 100% of the time at my office.

One logical conclusion here is that there is something physically interfering with the signal at work (that has always been there, but perhaps just now surfacing as a result of the 10.10.3 update). But that is such a far-fetched explanation.. it has to be something else.

Anyone else able to do a similar test?

 

[dastinger]

Wow, that is weird.

What I think is that people experience this issue for more than one reason. I say this because if it was something environmental why would it be working fine on Mavericks and not on Yosemite for me? And why would it happen on 10.10.2 and not on 10.10.3 for you?

Probably not even Apple knows what's wrong here since there seem to be so many situations. What's worst is that 10.10.3 didn't seem to fix this for anyone who experienced it before AND it made it start happening on Macs where it never happened prior to updating. I'm starting to lose hope on Yosemite and will pray that it's fixed on 10.11.

I may have figured out what was happening at least for me.

Having this installed was the culprit:
http://macid.co/

It was constantly trying to connect to my phone via bluetooth and not able to maintain the connection. So when looking at my phone, I would see the bluetooth icon pulsating on and off at a very rapid pace. This was what tipped me off that the phone was causing interference (basically every connect/disconnect was a brief interruption to the bluetooth service that was also connecting my mouse).

It would make sense because the app was working just fine before 10.10.3 and it's not unheard of for an operating system update to break a third-party app.

Simply quitting the app on my computer and killing it on my phone immediately solved the lag issue for me. That being said, I still get random disconnects (noticeably more frequently than before 10.10.3), but the LAG issue is definitely gone.

I'm guessing that not everyone having this problem has that specific app installed, however I think the takeaway here is to check your phone to see if a third party app or even a native app is somehow constantly trying to connect to the computer. Since my mouse will still disconnect (and eventually reconnect) more frequently than it should, I do think that this is still a Yosemite bug to some extent, but perhaps there are some third party apps to blame as well. At least the lag part of the problem is gone though.

Thanks a lot for posting your fix. Glad you've done it. Unfortunately, I don't even have my phone's bluetooth turned on and the only thing with bluetooth connectivity that I've got near my Macbook is the Macbook itself (and Magic Mouse ofc). Still hoping Apple fixes it.

 

[farleysmaster]

I've been having issues too. I'm not sure if it's knew since the upgrade but it's driving me mad. My magic Trackpad cursor is jumping all over the place.

 

[farleysmaster]

I turned off handoff and restarted in safe mode. No lag.

 

[dastinger]

How do you turn off handoff? And why did you restart in safe mode afterwards? Can't you use your Mac normally with handoff disabled? Also, does it stay disabled or do you have to disable it every time you restart?

 

[farleysmaster]

Just because someone mentioned testing in safe mode. Just going a permission repair (which I predict makes no difference) and then will reboot in normal mode

Handoff settings are in general settings I think. .

 

[farleysmaster]

I've restarted in normal mode. Everything is fine. I'll probably try switching handoff on again tomorrow to see if it still works. I don't actually really use the handoff features but I do prefer everything to be working...

 

[dastinger]

Thank you for your feedback. I'll wait for 10.10.4 and finally upgrade again. Let's hope most is fixed. Mainly this and the UI lag.

 

[Cyloncat]

Following the 10.10.3 supplemental upgrade, my Magic Trackpad is working again. (mid-2012 15" MBP, non-retina). Most of my usage with this machine is with external monitor and keyboard, so having a working trackpad is a big deal.

So happy to have it back; I hate using OS X with a mouse. I do hope this is a permanent fix.

 

[Macula]

It looks like you need a dGPU to have a proper cursor under OS X… [sigh]

 

[dastinger]

That doesn't make a difference. When you have an external monitor connected you're using the dGPU and I still had cursor lag. So did Cyloncat from what he's saying.

The damed lag is so annoying. I think I see a reinstallation of Mavericks coming in the near future for me. It's such a pity that this one super annoying trait can't be eradicated from OS X Yosemite. I understand that not ALL users are having this problem but it's driving me batty. There are enough people with this issue that Apple should address it.

 

[farleysmaster]

Have you tried turning off handoff? I turned off handoff (Still lagged), restarted in safe mode (lag gone), repaired permissions and rebooted in normal mode (now no lag).

I'm starting to notice a lag too. It's frustrating because I just added 64GB of RAM and the mouse makes it feel like there is only 4gb!

We have similar setups. I read somewhere that the older bluetooth cards in these Mac Pro's could be culprit. I may have to try a wired mouse...

No it has nothing to do with having an older BT card. I have the latest and greatest in mine, it has wireless AC/BT 4.0 LE. It's an apple card and works perfectly with Handoff/Continuity.

I always thought this was because my computer was getting out of date. Recently I added 64GB RAM, 3.4GHz 12-core, Radeon 7950, and an Apple SSD 1tb. So now I think it definitely has something to do with Yosemite.

I feel like Apple is coercing us to upgrade to newer hardware. Part of their master plan.... I hope I'm wrong.

No, I don't think buggy code or even incompetent coding is Apple's grand plan. Many people don't have this issue. It's a Yosemite vs GPU issue I believe. You have some really good specs. on that machine. Very similar to my own. I'm guessing that if I had went with the GTX line of GPUs I wouldn't be posting in this thread.

 

[farleysmaster]

I switched handoff back on and everything still seems fine.
