wireless Apple keyboard stalls requires restart

I'm just confirming that this issue continues in the release of 10.11.4. Keyboard and Magic Trackpad work fine; Keyboard and Magic Mouse work fine; Keyboard with Magic Trackpad and Mouse all connected via Bluetooth and the "stutter" returns. I guess it's time to toss out the old peripherals, Apple's not going to fix this!

I agree that this issue still persists in OS X 10.11.4. I have probably submitted fifty or so reports to Apple through Feedback Assistant in the last few months. They have contacted me through Feedback Assistant twice and asked for more information. I have submitted the information they asked for, but so far no solution. This issue only affects my late 2014 27" 5K Retina iMac. I have a mid 2011 iMac that has not been effected by this issue. I am just going to keep submitting reports, hoping this will get resolved. I did not have this issue before OS X 10.11. So far turning the keyboard off then back on again works every time, but only until the next wake from sleep via the Apple Wireless Keyboard. Waking with the Magic Mouse or Magic Trackpad still seems to work good at avoiding the problem, at least for me. Console messages seem to suggest that Bluetooth is not making a proper connection to the Apple Wireless Keyboard when this issue happens.

Most posters on this forum are saying that this is only a problem with El Capitan but I've had it for over a year and I'm currently running Yosemite 10.10.5 on a Mid 2012 Mac. So it may have been in previous major versions of OSX but is now being seen by more users.

I have tried just about everything to solve it with not much luck. I don't have the "preventing the computer from sleeping automatically when display is off" option (or at least I'm not seeing it) in Yosemite. I'm going to try turning off the Magic Trackpad and just use a mouse for a while as suggested by some people here and see if I get any luck. If that doesn't work I'll set my MacBook to never sleep, even when on battery. But that might cause other issues when the computer runs out of battery overnight.

I've had this problem after upgrading to El Capitan. Oddly enough, I recently discovered that the keyboard works fine if I wake up the system by clicking the mouse rather than the keyboard.

The issue continues in Mac OS X 10.11.5. Is this a dead issue for Apple??

Issue continues in betas of 10.11.6. Really hoping that macOS 12 will fix this. Giving up that this will be fixed in El Capitan.

Out of curiousity is everyone using this have the older wireless keyboard/mouse/trackpad? If I was sure the new peripherals solved the problem i might upgrade (as having rechargable batteries is nice), but I don't want to waste money if the same issue will persist fter investing more money.

I do have the older wireless keyboard, mouse and trackpad. I, too, wonder if upgrading to the new rechargeable peripherals would eliminate the problem.

Problem still exists in macOS Sierra! My guess is it is never going to be solved. Anyone try getting the newer rechargeable input devices? My other though is that I am having a bluetooth interference problem since i own a ton of bluetooth devices.

I was wondering! i haven't tried using my trackpad for ages and can't say I missi it. Time to list it on eBay!
