after osx 10.10.4 update mac mini won't wake up from sleep

I have made the OSX 10.10.4 Update on my Mac Mini (late 2012) - now if thet mac mini goes to sleep for a longer time (1 hour) the status led is permanent white (on) but I can't wake up the mac mini any more. If I push the power button it wakes up but all usb devices are frozen - no keyboard an mouse and after a while the system searches for a bluetooth keyboard/mouse.

Before the update all was fine...

btw. has apple made a firmeware update combined with the 10.10.4 update - if I boot the mac mini now I will get a black booting screen (not grey as before)....?

thanks for help

Try booting to Recovery and repairing the startup disk

Reset the SMC and PRAM/NVRAM

Yes, i believe there was a firmware update as part of 10.10.4. My screen is also now a black shade..

Did this already - no luck. MacMini freezes USB after a while in sleep modus...

... so I am not alone - can reproduce the freeze like that:

- put MacMini to sleep - now the status led goes and comes as ever

- wait about an hour or so and suddenly the led goes to on (like the mac mini is running) but the screen remains black

- no reaction of keyboard and mouse (usb is frozen, screen is black) and mac mini is on...

- a short press on the power button of the mac mini gets the screen on ... but all is frozen, no keyboard, no mouse and the system searches for a bluetooth device...

PLEASE APPLE SAY WHAT YOU DO - IF YOU MAKE A FIRMWARE UPDATE DECLARE THIS....

So I had previous to the 10.10.4 Update a good working mac mini - and now it freezes on going to sleep and the worse is that I can't revert this????

btw where can I tell this to apple....?

thanks

Well it seems that apple coupled the 10.10.4 update with a firmware update (would be nice they had declared it so...) for the mac mini.

I can identify now severals draw backs:

- no usb after deep sleep

- I can't choose anymore an other system on booting (alt-key) - if I choose my 10.10.3 backup disk it won't boot it...

A work around for the usb/sleep thing for me is to not wake up the mac mini via keyboard - don't touch it as I seems to freeze it... just press the power button once and it will awake non frozen...
