iMac 2014 5K Bluetooth Trackpad Problem after sleep

Hi all,

I was all excited to get my new iMac 2014 5K two days ago. The display is simply stunning. I am however struggling with a trackpad problem and had several support calls with Apple already.

After the iMac goes into sleep (and enters deep sleep after circa 2-3 minutes), it cannot be woken up with trackpad or keyboard anymore, After pressing the power button, it turns on again (no need of restart). The trackpad is by then however useless. The pointer movements are extremely slow and none of the gestures work. I tried the following instructions in different forums but none of them worked. It cannot be that all new iMac 2014 users are having this problem!

Unpairing and pairing the bluetooth devices
PRAM reset (multiple times)
SMC reset (multiple times)
Safe boot
Deleting system plist files and restarting
Changing batteries of trackpad.
Turning wifi off (between that I am connected otherwise at 5Ghz with 802.11ac)
Turning off all devices in the house that transmits signals (router, DECT phone etc)
Testing Trackpad with Macbook Air with Yosemite installed (sleep and trackpad works fine with it)
SSD format and reinstalling Yosemite (and no further apps on top of it). This means iMac is as good as out of the box with only Apple bluetooth keyboard and trackpad connected.

After the problem starts I see the following messages in Error log

30.10.14 22:51:08,000 kernel[0]: [BNBTrackpadDevice][setReportWL][1c-1a-c0-f2-1e-82] Could not send DATA command via interrupt channel - 0xE00002BE

The day before I got the iMac 5K, I sold my perfectly working Late 2013 iMac with Yosemite on it. It had no issues with trackpad.

I see a long thread here from Macbook users

Bluetooth problem with OSX Yosemite: Magic Mouse and Keyboard

There people mostly complain about latency and not the sleep problem. Does anyone else face this problem with the new iMac and Yosemite?

Regards,

iMac (Retina 5K, 27-inch, Late 2014), OS X Yosemite (10.10)

Has anyone a chance to test the newly released 10.10.1?

AppleCare is the overarching name for Apple Support, both hardware and phone.

AppleCare does start concurrent with the purchase and coverage is from the date of purchase.

So for example, if you purchase AppleCare on a new Mac, the coverage starts immediately and lasts for three years from the purchase of your Mac.

If you purchase AppleCare near the end of your warranty period, coverage still expires three years from the purchase of your Mac.

Why purchase AppleCare with your Mac? There's no reason not to, and though hardware coverage for that first year is covered by both, you get phone support with AppleCare after 90 days, when your free support with purchase runs out.

From the AppleCare pages at the Apple Store:

Not yet. I installed it tonight, so will report back by tomorrow. Anyone else?

The 1st build of .1 did not fix it... but the version # of the BT kext has since changed...

I installed 10.10.1 (just released yesterday). Problem seems to have been resolved. I have only tested it once, but my keyboard and mouse worked fine after sleeping for 3 minutes.

It's only been a day, so take this with a grain of salt, but for me, 10.10.1 also seems to have solved the issues. I'll continue to monitor. Anyone else?

My iMac slept overnight and I woke it using my Bluetooth trackpad. It's been working fine all morning since then. Fingers crossed that it was fixed in 10.10.1. So far it looks promising.

I have my Imac since 3 weeks and was working fine, but now since 4 days ago the trackpad is going crazy sometimes works fine, then it doesn't move at all and then works slowly, and then normal, then back again. Last time I reboot my Imac and works perfect, but then again. now I have made the upgrade bu still the same. any news ??

I tried the developer pre-release of 10.10.1 and it didn't fix the problem, then last night I installed the public release of the update and everything seems to be great now, now more issues. I let it sleep overnight and when I was at work, it woke up fine with the trackpad/keyboard everything was normal both times.

For me it feels like it's case closed 🙂 Thanks you Apple.

I did NOT have the problem before. But right after I upgraded to 10.10.1 I started to have the no-scroll problem with my Apple Mouse. I tried using a USB mouse and it wouldn't work at all; not even power on.

I unpaired and deleted the mouse from BT prefs. Restarted. Now both USB and Apple mouse (paired up anew) work fine.

I've had coming out of sleep mouse issues with other Macs too, under both Yosemite and Mavericks.

I have a Magic Trackpad on a 2-year old iMac 27" and it is still behaving very badly after the 10.10.1 update. It ran fine for a while, but after about 15 minutes went back to randomly dropping connection and giving me random click events.

My other bluetooth devices seem fine, though. Apple Keyboard works, as does a Logitech bluetooth mouse, which is getting me by right now until they fix this. Only the Trackpad is flakey.
