10.10.4 Keyboard not working after sleep (mac min)i

After the 10.10.4 upgrade I thought my computer will no longer wake up from sleep without a hard boot (kill from power button and then start up again). After all basic repairing of permissions, resetting nvram and SMC I turned power saving off hoping the computer would work as long as it does not sleep (it does).


Looking further into the issue I noticed that by quickly pressing the power button I can get it to wake up, only I can't enter my password on the login form. I took a wireless Microsoft media keyboard from another system and tested with it and it works.


So basically, since 10.10.4 my Apple USB keyboard does not work after sleep until the computer is completely restarted. With a quick google search I find others that have the same issue and all of them seem to have a previous gen Mac Mini like me.


specs (unchanged from before)

Mac Mini I7 (quad core)

16GB ram

1TB Sandisk Extreme SSD

Nec Spectraview display

Apple USB keyboard (A1243 EMC No: 2171 probably older gen)

Mac mini (Late 2012), OS X Yosemite (10.10.4)

The more reports Apple gets the more likely they will address your issue.


HOWEVER, I'm sure this does not happen to everyone, and I strongly suspect Apple employees use Apple keyboards. So maybe there is something else going on with your system.


Do you happen to have another USB keyboard you can try? USB devices (or their cables) do fail from time to time.


Have you tried a different USB port?


You have replaced your disk with an SSD (I do not object, as I've done the same for 2 of my Macs), but it is a difference.


Try booting into Safe Mode (it will be a slower boot). Safe Mode should avoid starting all non-Apple additions. Now experiment with sleep/wake and see if there is any difference.

Try a different newly created account (System Preferences -> Users & Groups).


If you have an external disk you can install a bootable system on, or clone your current boot disk, then set System Preferences -> Startup Disk and boot from the external. Does the behavior remain the same? Or if you really want to eliminate all possible installed software conflicts, install a clean version of Yosemite on an external disk and boot from that. See if there are any sleep/wake issues.


These are the best suggestions I can give at the moment.

I just bought Mac Mini with preloaded El Capitan. Unfortunately, it seems that exact problem that were described in this post seem to affect this new Mac Mini as well. After sleeping, or even if I prevent sleeping but after long time with display off, I get no response with keyboard or mouse. Even if I disconnect keyboard and mouse, it does not help, and the only way to regain control of keyboard and mouse is hard shut down with pressing on power key for several seconds....


I looked up firmware update 1.8 from Apple, but it states that my Mac Mini does not need this update. So, I am not sure what I can do to fix this. It is very annoying to do hard shut down so often in order to simply use keyboard and mouse....


Do anyone know how to fix this???

The keyboard of my macbook air (2008) freezes after closing the lid or putting the laptop into the sleep mode. It's loaded with El capitan.

I spend hours and hours on internet to find out what it is. A lot of posts suggest to reset PRAM and SMC. Other posts suggest to delete old bluetooth connections. This did not gave a good result in my case, it worked sometimes for a short period but the freese came back.


Now I found a different cause: a plugged in usb connection. It seems to be that the usb port is not disabled during sleep, which is not right. I checked it with my iPhone cable and iPhone. It looks like that a usb device which is asking current is interfering the sleep mode. The reason I have a usb device connected is that I use a usb wifi dongle. Any advice?

Hello,


same experience at my system:

  • fault: USB port does not recognizes any change after sleep and looks dead.
  • fault solution: restart the Mac
  • workaround: disconnect the USB device before going to sleep, reconnect after wake-up.
  • parameters:
    • El Capitan, 10.11.3
    • MacBook Pro (Retina, 15', Mitte 2014)
    • appears with USB 2.0 Hub and with USB 3.0 Hub connected to the port.

It looks like a new bug report to Apple is required, what I shall do.

Dear community,


sorry to say - or happy - the bug disappeared at my system and I can not reproduce again.

This was the advice the Apple developer support told me:


Apple Developer Relations09-Feb-2016 11:45 PM


Engineering has requested the following information in order to further investigate this issue:


Please attach a sysdiagnose when the usb devices stop working after sleep.

More on running sysdiagnose:


1. Launch Terminal.app

2. Enter this command: sudo sysdiagnose

3. Enter your admin password

4. When sysdiagnose has completed (may take several minutes), locate the new sysdiagnose file in /var/tmp or /private/var/tmp. Upload that file.

An alternative approach uses a key command:

1. Press Shift-Control-Option-Command-Period when the issue reproduces

2. Wait for a few minutes (you can release the keys).

3. When sysdiagnose has completed (may take several minutes), locate the new sysdiagnose file in /var/tmp or /private/var/tmp. Upload that file.

Thank you.

Please provide your response or results by updating your bug report and compress any bundled files (e.g. nested folders) prior to uploading.

If someone else gets the bug repeated prior to me, the Apple support might welcome her/his results, too.

If you already captured the bug this way, I guess you need to open another bug report on your own, but you can refer to my number above, if you suppose that it is the same.

Many thanks for your help!

So you are talking about your single keyboard?

My problem appeared only related to an externally connected additional keyboard, but I guess even the main keyboards are USB connected and, yes, I can imagine that you might have the same problem with those.

If you have any other external keyboard available, you could try to use this for the bug report generation, because it seems that not all USB ports become dead at once.

Short before the bug appeared again at my computer and I was able to generate the sys diagnosis file. But this does not mean that you should not generate such a file on your own for an own bug report. Such a sys diagnosis could help but multiple could help even more, because one could look for equal patterns at the reports.

I hope that the apple people will stop the report avalanche by a „bug found“ message to this blog.
