Mac Mini either won't sleep or continually wakes up from sleep

Well, I think I've tried everything...
My mini won't sleep on it's own through energy saver. I can force it to sleep by choosing it in the apple menu - and it will stay asleep. And it will go to sleep through the schedule. I installed "Please Sleep" which forces the mini to sleep but it wakes up 10 seconds later. The monitor sleep works fine.
I unplugged all USB devices - still didn't work.
So it must be a rogue process or something? Is there a way to know which one is forcing the Mac to stay awake? Or any other suggestions?

If you haven't already, try resetting the SMC per this link: Intel-based iMac, Intel-based Mac mini: How to reset the System Management Controller

Mac mini 2014 won't do 5.1 surround sound from HDMI port

I can't seem to get my Mac mini 2014 to do 5.1 surround sound from the built-in HDMI port to my home theatre system. When I run the Audio MIDI Setup program the only option is 2ch-24bit (stereo). Now I didn't have this issue when I tested it with a Mac mini 2012 running 10.9.5. It allow me to select 6ch-24bit (5.1) and Encoded Digital Audio. I also don't have an issue with the Mac mini 2014 if I use a Belkin Mini DisplayPort to HDMI Adapter connected to one of the Thunderbolt 2 ports. It does 5.1 surround sound just fine. So is there something wrong with the built-in HDMI port on the Mac mini 2014 or OS X 10.10?

Mac Mini late 2012 with Mavericks don't wake up from standby mode

My Mac minin used to run with OS X ML 24/7 without any problem. After Update to Mavericks the Mac won't recover from standby mode. I have to power off the mac.
I cleared nvram, pram, installed Mavericks second time.
What can I do? Return to Mountain Lion?

I gave Mavericks a second try. It failed. Made clean install ofe mavericks, setup user manually, reinstalled my most needed applications. The mac mini will not wake up from standby mode (blanc screen -> must reboot/hard reset; spinning beachball -> hard reset)
I reset nvram and pram.
Any advice? any chance to get informations by apple?

Leopard won't wake monitor from sleep on Power Mac G4

I had no problems with my Power Mac dual G4 867 while running Tiger, but immediately after a clean install of Leopard (a fresh install - no third party apps) my Dell 17 inch LCD monitor will not wake from sleep.
The monitor comes on just fine when the computer first boots, but if the computer sleeps, and I wake it by hitting a key on the keyboard, the drives spin up and I can hear that it thinks it's working just fine, but the monitor won't wake.
I know that the computer is working fine despite the sleeping monitor because I can hear VoiceOver working after a clean install of Leopard (if I let it sleep after the Welcome movie) while asking for user information.
I reinstalled Tiger, and the problem disappeared. The monitor wakes reliably from sleep with a fresh, clean install of Tiger. But with Leopard, even turning off and on or unplugging the monitor doesn't wake the screen.
I have reset the PRAM, the PMU, and the Open Firmware (the firmware is up to date). I even opened the case and pulled and re-seated the video card. Nothing seems to work, so I have just set the computer to never sleep. Not a great option, given the insane fan volume in the G4 MDD model.
Thanks for any suggestions anyone can offer.

I'm having similar problems with both a new MacBook Pro and a new Mac Mini, both connected via a Gefen DVI switch to a Dell 2005FPW monitor. Putting the MacBook Pro to sleep while in dual monitor mode will crash the machine. Putting the Mac Mini to sleep won't crash it, but the monitor won't wake—the computer wakes, but the monitor stays black. I can use Screen Sharing to connect to the Mac Mini and restart it (the only fix, as far as I can tell).
I suspect this is a software issue, because my old PPC Mac Mini would usually wake from sleep. The Gefen support people say this shouldn't be happening.
Anyone having this problem should probably post it as a bug at Apple's Feedback page. I think reinstalled, resetting PRAM etc. is probably a waste of time. Meanwhile, don't sleep your monitor.

My mac won't wake up from sleep, what can i do

My mac won't wake up from sleep, what can i do

Can you say more about thermal cut-off? My mac has beene having problems waking from sleep and I have noticed that I hear the fan running ever so slightly in the background. When I depress the power button for a second the fan shuts off.
Just open the side an dlook to see which fan it is. The lower fands are easy to see as well as the video card fan.
When you push the power button and that fan goes off is the machine now fully off? No power light? No fans spinning? Now drives spinning?
I don't recall what I did when my machine shut off with the one exhaust fan running. I think the obvious thing I would have tried would have been to push power button for 10 seconds to shut it down fully. That or actually pull the plug.
When this happens the only way to use my Mac is to restart via the power button.
Then I guess that answers the first question. It must have turned off since pushing the power button again was the normal reboot.
I can't find any helpful info on thermal cut-off so I was wondering if you could explain what it is, what causes it, and more importantly what I can do to fix it?
That was my term for it. What else could it be? Without its fan video card would get extremely hot and throw off all that heat. Whats the point of having temperature sensors in so many places other than to use that info to protect the machine against damage due to overheating? So my assumption was card gets hot, sensor (probably the pci slot 1 temperature sensor) senses it, kills the machine. It's also seems logical to me that the circuit(s) handling temperature overloads would want to keep a exhaust fan running to dump the heat out of the machine to further protect any damage from the heat.

G5 won't wake up from sleep & fans go to high speed ???

G5 won't wake up from sleep & fans will go to high speed within a few minutes of it going to sleep. Whether I put it to sleep or it goes to sleep on it's own per my preferences in energy saver. I have to manually shut it down by holding the power button in. I ran the system hardware dvd and results were good. I have repaired permissions, reset the PRAM.
Any ideas?

"Try Disk Utility
1. Insert the Mac OS X Tiger Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, test sleep in Safe Mode, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

After update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.

hello,
after update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.
the used ports appear to be "killed"; the unused USB ports seem to work, but the Mac works in slow-motion.
The only "solution" is to restart my Mac.
- SMC-reset, PRAM-reset or repairing user rights had no positive effect; what is the solution - a bug-fix-update???

I have a mac mini (A1283) with OS 10.7.4. Upon upgrading to 10.7.5 it did not start up again. Instead, the light was on and the hard drive did not start up. The light on the connected USB mouse was not lit.
My solution:
Cold start with Command-v pressed.
This should start Verbose mode (see http://support.apple.com/kb/HT1492 ).
What happened on my mac mini was that the grey startup screen with the Apple logo appeared for a long while before the login screen came.
Maybe Cmd-v set open firmware params and fixed some corruption.
Anyway: my mac mini works again.

Mac Mini hangs at hardware boot and at wake-up

I've got a brand new Mac Mini Intel Core 2 duo 2GHz with 2GB RAM.
50% of the time, when I power it on, there is no "start" sound and
the screen remains dark. The "power on" LED is however switched on.
After a force shutdown, I can start it fully OK. The same behaviour
is observed in 50% of the wake up from sleep: LED on no longer blinking
and dark screen. Force shutdown and power on again solves the case.
I've already reset the PRAM twice without any visible effect.
I've tried the SMC reset procedure also without any visible effect.
The Apple Hardware Test detects no hardware failure and the disk
verification ends up with no problem detection.
The Mac Mini is connected with a 2-year old Eizo L557 flat screen
with a resolution 1280x1024. It worked fine with an older G4 Mac Mini.
I have an Apple pro keyboard in version 4.10 and a 3-button+scroll wheel
Logitech wired optical mouse.
Once started, the Mac simply works fine.
Does anyone have a clue what the problem could be ?
Many thanks in advance

I have the same problem I am hung up right now color wheel spinning around, color wheel cursor, and I have a dark screen I guess I have to hold in the button or something to restart? What do you think? My macMINI is only 2 wks old has 1 gig ram its the 2.0 gHz intel C2D I'm going in tomorrow get upgr extra gig makes 2 gig. I'm not really insightful with this machine how do I turn it off or reboot to get out of this hang'n effect? Do I need to optimize the HD how do I do that I'm from win platform is there a scan/error fix disk / defrag procedure or disk clean we do on the mac what is the procedure on this. It seems your suggesting maybe mem error causing this hang'n on the mac, is that right? Even though I've had the cmptr only two wks I've only used it 4 to 5 days since I was over seas for 12 days.

G3 Bronze Keyboard won't wake up from sleep

I have a hand-me-down Powerbook G3 Lombard 400 Mhz (bronze keyboard), with a dead main battery. It works great with the power adapter, and has just enough charge for me to move it from one outlet to another without shutting down. I'm trying to set it up for use as an Itunes server connected to my home stereo, which is fine because it will always be plugged in.
The problem is that the laptop won't wake up from sleep. This morning I noticed that the display and HD seemed to be sleeping, but the fan/processor buzzing noise was still going (there were no lights other than the little green light on my PCI card). I couldn't figure out any combination of keyboard or power key strokes that would either wake it up or shut it down. I unplugged it, waited half an hour or so, and it finally shut down. I then plugged in, hit power, and it started and booted perfectly (after the expected disk check for abnormal shutdown). Then this afternoon, the whole thing was sleeping (I think -- no sound, no lights other than PCI card light), and again it wouldn't wake up. Again, I unplugged, let it power down (waited for the PCI light do die), the replugged and it started up just fine.
Any idea what gives? Or what I do when it's sleeping? Right now, I have changed the power saving settings so that it never goes to sleep, but I'd really like to let it sleep when people forgot to turn it off...
thanks!

aldpol,
There are many causes for sleep issues and you just have to wade through them one at a time.
You can always force a Lombard or newer powerbook to shut down by pressing/holding the power button until it turns off. As you have noted, this is an undesirable process since you can corrupt the HD.
I would start the troubleshooting in this manner:
1. Unplug all peripherals (PC cards, mouse, everything).
2. Reset the power manager:
http://support.apple.com/kb/HT1431?viewlocale=en_US
3. Now put the powerbook to sleep via the Special menu, wait a minute or so, then wake.
4. If no success, restart while pressing the shift key until you see the message 'extensions off', then release. Now test sleep/wake.
If number #3 is successful, one of you peripherals is probably the troublemaker. If still having issues, please post back with more details if possible.

My Mac Mini shuts off when I try to wake it up

Whenever I put my brand new Mac Mini to sleep, then push any key on the keyboard to wake it up, the pulsing green light turns off. Then I can't even start it up when I press the power button. I need to unplug the Mac and plug it back in, then I can press the power button to start it up. I just set it up yesterday and it worked fine, but tonight I can't wake it up. Did I change a setting by mistake?

I have the same Problem, Reported here:

Try resetting the PMU (power management unit).
Remove battery and power adapter.
Hold down power button for 10 seconds.
Reinstall battery and attach power adapter.
Hold down Command-Option-P-R, a total of four keys, and press power button. Don't release the keys.
Continue holding the four keys until you hear the startup sound twice, then release.

MacBook won't "wake" up from sleep, when being folded

When I "fold" computer it goes to sleep. But, when I flip up the screen again, my Mac won't "wake" up from sleep mode anymore.
Do anyone know how to fix this problem?

I have a MacBook 2.26 GHz Intel Core 2 duo, Snow Leopard 10.6.8.

I've solved my problem.
I have reset my MacBook's PRAM settings.
It's very easy: link: http://support.apple.com/kb/HT1379
Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.
Hope this helps
Best regards,
Christian

I would opt for one 8 GB stick so you would have 10 GB. total. This says really no practical advantage in dual channel memory

Early 2008 Mac Pro wakes up from sleep with Mavericks.

Ever since I upgraded to OSX Mavericks on Tuesday, my early 2008 Mac Pro keeps waking up from sleep mode every couple hours. It goes back to sleep again on its own though after a minute, so I'm thinking it's some kind of new automated feature that I'm not aware of. With the Mac Pro being fairly loud when it wakes up from sleep mode, it woke me up three times last night! Is there some kind of option in the system preferences that I'm not aware of that can deactivate this new behavior? I usually only shut down my computer once a week, and keep it in sleep mode when I'm not using it most of the time, but I'm going to have to start shutting it down every night now to keep it from waking me up throughout the night...

Hello MARl0,
You may want to disable the Power Nap functionality, if available, in System Preferences -> Energy Saver.
