When my Mac Pro goes to sleep, it will not wake up by just slapping the (Mac) keyboard; I have to hit the power button on my Mac Pro to wake it up. From what I’ve found online, it seems like it might be going into something called “deep sleep.”

It’s not a huge inconvenience, with the exception that—if my speakers are powered up when the computer goes into deep sleep—it sends loud crackling and thumps through my system, which can’t be good for my speakers.

(BTW: Other than Time Machine, I have no spinners in my system; internal flash mem + two external SSDs.)

Questions:
1. Is this really deep sleep, or something else?
2. Is this typical behavior? My MacBook Pro doesn’t do this.
3. Is this desirable, and—if so—why?
4. If not, how do I reconfigure so it just goes into “normal sleep” instead of “deep sleep?”

Thanks in advance.

Have you disabled AppNap globally? Are you using any 32bit apps? If AppNap is disabled, shouldn’t be an issue.

Are there any FW or TB devices connected? If so, what?

How is your Time Machine device(s) connected — Ethernet, wireless, other?

Thanks, Mike....
Good questions, all...
• I haven’t disabled appnap globally... didn’t realize that was possible. I found instructions here: http://osxdaily.com/2014/05/13/disable- ... -mac-os-x/
and will try tomorrow.

Not using any 32-Bit apps.

Time machine drive is connected via USB.

My external sample drives are connected via Thunderbolt (2).

Any further suggestions welcome. Thanks again.

Are you using a wireless keyboard? I've had this happen with my iMac, and I think it is the result of my Bluetooth card going offline. Resetting the SMC and the NVRAM seemed to help.

EDIT: I mean Bluetooth, not WiFi

DP is one of a few that doesn’t get along with AppNap. I hav a couple of others.

I hadn’t considered Bluetooth but that is a possibility.

Time machine drive is connected via USB.

This is where I’d look for the problem. WiFi and Ethernet never have sleep issues and USB (and FireWire) can. 2013 Mac Pros support 802.11ac WiFi — otherwise, Ethernet. No reason to tie up a TB port for TimeMachine. 802.11a/b/g/n WiFi is too slow anymore.

Keyboard is USB, but I’m using the original Apple Bluetooth trackpad.
