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)

Just saw this - apple release 10.10.1 beta to developers. Hope it include the fix. Apparently there are a lot of report of BT and wifi issues on 10.10

Focus areas mentions wifi, but not bluetooth. Does not sound too promising!

Well,

the releases does update the BT Software Version (it doesn't update the firmware); it looks like we all have 4.3.0f10 14890

The .1 release updates to:

Apple Bluetooth Software Version: 4.3.1f1 14950

Since the 5k isn't a development machine I am hesitant to try it out in beta, but there it is...

I have the same problem. FYI, I have no other hardware attached to this machine. I connect wirelessly via the latest Time Capsule. I trust Apple will fix it but why doesn't it issue send an email to all people who ordered this combination of hardware and let us know they are working on it?

I remember we had an Intel based, highest-spec Mac Pro (last of the cheese graters) and until a firmware update, the systems tended to restart when put to deep sleep, then woken up 😉 In that regard, this ain't so bad 😉

No updates in Germany yet through developer seed. Maybe the mirroring takes a while.

I just realized that I had an Apple store download in background and that was the reason for sleep=0. Now the sleep is back to 1.

In order for it to show up in the app store, you need to use the seed configuration tool to enable development builds. That said, the build is available on the US developer site now (it was several hours after it was available through the 'seed' program) - check it when you have a chance.

Thats exactly what I did. Thanks for the hint though.

Between that how did you get the Bluetooth version without installing?

I Did install - on one of our deV systems, which unfortunately isn't the iMac 5k 🙂

Ok got it 🙂

Could you please send me the ktext files from 10.10.1? I guess you can find them under

/System/Library/Extensions/

as IOBluetooth**.ktext (2 files I guess)

Apple might not like sharing beta files here. It would be great if you could mail me directly. My id is the <forumID>(at)yahoo.com

Thanks in advance.

Thanks for the files. I can confirm that the bluetooth problem is NOT fixed with 10.10.1 (Apple Bluetooth-Softwareversion: 4.3.1f1 14950)

I guess the bluetooth problem is rather new (compared to the other problems) and we still need to wait for Apple to starting working on it.

Today I got a reply for my bug report from Apple asking for log files.

Thanks for much for trying it out.

Sigh, too bad.

Yeah, Apple asked me for the BT diagnostic files about a week ago, as I filed a bug report as well, and provided same day. Haven't heard anything since then, so far...

nirmalts,

I appreciate your testing this out. Alas it is not fixed in the up coming release.

I bought the iMac with retina 5K display this past Sunday and have been having the same issues. Everything worked fine out of the the box and then after awaking it from sleep mode, I lost scrolling functionality on mouse and media/screen functions (volume, brightness, etc.) on keyboard. It shows as if it's connected but then when you go into the preferences section for each, it doesn't show options for full functionality for either. I restarted it and everything worked again but then just wound up losing the functionality again after it goes to sleep. I thought I was taking crazy pills! It's good to find out now when I search this issue that it's popping up that others are having the same problem (If you can call that a "good" thing...but at least it's not just me and hoping for an Apple fix now). I had a magic trackpad that i connected too and the same thing. It has basically functionality but loses the ability to scroll and all that multi-touch stuff. Also, and not sure if this is related, it stated my batteries in it were almost dead even though they were basically brand new (albeit I did take them from a bluetooth keyboard I had put them in week before that I had barely used....but who knows if they somehow drained that badly while in there).
