Q: iMac 2014 5K Bluetooth Trackpad Problem after sleep

I have been talking to a friend in Florida who has bought a maxed out 5k Retina and has no problems whatsoever with issues that I have experienced and has tested a few links I sent him that cause me immediate problems.  Not so on his 5k Retina.

My issues are thus:

1. Magic Mouse losing scroll function after sleep.

2. About 50% of videos (Vimeo, Youtube, FB etc will not play full screen - it blacks out.

3. Processor seems to labour for even simple tasks like web site slide show, or watching a movie.  This is indicated by the fan immediately switching on.

4. SMPT does not function for several eMail accounts.

Upon migrating my complete Retina content via Time Machine to my standard 27 inch iMac, all these problems disappeared.  

The one major thing that is different in the machines my friend in Florida and I own, (we both have i7, 32GB RAM, 4GB Video, 3TB Fusion drives) is the mains voltage and frequency.  Here in the UK and Europe we have 230v at 50Hz whereas the USA has 110v at 60Hz.  I don't thing voltage would change anything, but frequency might well be a factor.

Therefore it would be interesting to know what voltage and frequency is being used by commenters in this post.  Are we all in Europe or are USA users also experiencing the same issues?

Has anyone a chance to test the newly released 10.10.1?

Thanks.

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.

I am having the same problem on my week old iMac. 

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?

All,

Thanks for the updates. Please keep them coming. Unfortunately, I am not in a position to contribute.

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.

Yes, I confirm all the same problems.

4GHZ i7

AMD Radeon R9 M295X

16 Gigs of RAM

3TB Fusion

10.10.1 did not fix the problem.

Using the power button to wake from sleep. After that, sometimes the trackpad works, the mouse never works.

Also the entire machine is very slow waking from sleep.

Hope Apple does something about this quickly because I can say that this was a very very very expensive computer in Europe!

I have two Retina 5Ks and I have had some Sleep/Wake issues. But 90%+ they Sleep for hours and wake with one click of the Trackpad.

Sometimes they will NOT wake so you need to use the power button to wake it.

I hope you find a solution.
