How is it very likely to be fixed in a future update? These problems have existed since October 2013 and when they originated they were completely debilitating MacBooks by locking them up to the point of needing a hard reboot every time it happened. This problem has been around in one form or another and Apple has been slow to respond. It's not a minute problem, it's a problem in the drivers for their own trackpad. Considering Apple has always led the way in trackpad drivers, I'm going to assume their long delay in finding a fix is because the problem is rooted deep in the product.

It may seem insignificant in day to day use, but what it implies is that there's something fundamentally wrong with the product line. That's fine if you can live with it, but rarely do I drop $1500 on a product that's flawed at a very basic level.

I don't know, we are not really talking about the same thing here. What is currently happening is that there is a split second delay between when you start touching the trackpad and when the mouse pointer starts moving, after you have taken your hands off the trackpad for at least 5 seconds. Nothing is getting debilitated or requires a reboot here.

It is the same firmware issues that plagued the 2013 rMBPs. This same error was being output when those issues were arising. I'm not saying my laptop is crashing, but it stems from the same problem. I don't believe that is very difficult to understand.

The issue is that Apple has allowed trackpad/keyboard firmware issues to continue for so long, even after claiming they fixed them with a firmware update. If you still don't understand let me know and I'll try to dumb it down further.
 
OK guys,
I've just noticed the same problem on my MBPr 2014 13" purchased last month.
This doesn't seem to be a hardware problem, just boot while holding the Option key.
You can clearly see that in the disk selection menu it doesn't show the same defect.
Plus believe me or not, with my iPhone plugged in, this defect just goes away..
:rolleyes:
Just checked the Console, no message at all. Seems that Mavericks think that the USB bus can be put to sleep as there is no peripheral that requires constant power. When the iPhone is plugged in this seems to be disabled as otherwise it wouldn't be able to charge.
Just tested with a USB key, same thing.
To me, Mavericks is faulty ;)

You are right, it doesn't seem to have the issue in the disk selection menu. I plugged in a USB flash drive to check if that would stop the issue similar to your iPhone and it did! So apparently it is the USB hub going to sleep?

I do think so, does anyone have Yosemite or Windows with Bootcamp to see if the issue remains? :)
Oh god, look into System Profiler, see that the Bluetooth is on the same USB bus?
Enable Bluetooth and see the defect vanishes :rolleyes:
So that's definitely it. Just sent a feedback to Apple :apple:

Okay, even if it stems from the same problem, it's not the same problem. If you were getting crashes and stuff, then I could understand the concern. But really, all we're left with is a little quirk in the system that really doesn't affect any day to day operations of the machine. Like I noted before, scrolling with two fingers results in a clean scroll no matter how long I've waited after the last time touching the touchpad. I had never noticed the cursor jumping issue, and I had to try several times to reproduce it.

Take any windows laptop, and I'll bet you a new rMBP that there are at bare minimum three times as many quirks in the system than are on the rMBP.

Well, I think you may be onto something. When I enable Bluetooth on my machine, then the stutter goes away, but only temporarily. As soon as Bluetooth goes to sleep, the same stutter reappears.

But I think it's pretty obvious that this is caused by the power management of the USB bus. The same also happens with the keyboard if you pay close attention: Go to a text input field, don't type anything or move the mouse for 5-10 seconds, and then when you push the key, it also takes a split second for the input to show up.

So I think people should just relax. It's a power saving feature of the USB bus. If Apple would turn off the power management, battery life would probably suffer. I'd rather have the battery life than getting rid of the stutter, but I guess it would be nice if Apple would let people choose.

Yeah I noticed this as well, enabling bluetooth seems to halt the problem temporarily. Once the same "power saving" feature puts the bluetooth controller to sleep the problem starts again.

EDIT: If this is a power saving feature, why doesn't this happen on MBAs or the 15" models? I think your fanboyism is getting the best of you...

I did mention I was able to reproduce the stutter of the trackpad with my 2011 13" MBP
 
I don't have this problem on my late-2013 13" rMBP (2.8GHz i7, 16GB RAM, 512GB SSD), surprisingly.

And I haven't experienced this on my spare baseline late-2013 rMBP (2.4GHz i5, 4GB RAM, 128GB SSD) either.


I have the the very same i7 mbp model. I've tried to recreate this problem numerous times but to no avail.
 
I turned on bluetooth on my mid 2014 rMBP 256gb 2.6Ghz and the cursor stutter is gone.

I guess you need bluetooth on for handoff to work in yosemite so its not all that big of a deal.
 
Are people still experiencing this on Yosemite?

my computer does it, it seems to be a software/firmware issue as many of you seem to be able to do it and I don't really want to return an otherwise great machine.
