Mac Mini REALLY won't sleep

OK, I have an Intel Mac Mini that really, REALLY won't sleep. When I try to sleep it, the heartbeat light on the front pulses, but I don't think the Mini is asleep, in that the external drives don't spin down (or they do spin down and then spin right back up again), and it wakes up too quickly. Also, when I try to use "Safe Sleep" ("pmset -a hibernatemode 1", or the Deep Sleep widget), the Mini doesn't deep sleep; it fakes normal sleep just like above (this used to work). I have tried all of the following:
1) Disconnecting all but a mouse and sleeping. Tried two different mice.
2) Resetting the SMU (15 minute unplug) and the NVRAM (CMD-OPT-P-R)
3) Booting from an external drive with a copy of a different Mini. Unmounted everything but the external drive first.
Is there anything else I should try?
Though I don't think it's relevant (due to point 3 above), the Mini has an internal drive with 2 partitions (a large Mac OS X partition in a RAID 1 with an external miniStack, and a small blank Boot Camp partition for a future XP install) and a miniStack with three partitions (the RAID mirror, a static backup, and a simple storage space). The hardware shouldn't be relevant due to point 2 above, but is a Ministack, a Logitech Marble Mouse, a Kenginston Orbit, an Apple Keyboard, a Dell 19" monitor with USB hub, a Griffin iMic, a Canon MP760, and an iSight.

Try downloading a copy of OnyX from
versiontracker.com...I find it solves almost
everything as it runs high level UNIX maintenance
scripts, such as Cron job, clearing kernel caches,
repairing permissions, etc.
Otherwise I'd try reset the PRAM by holding
Option-Cmd P, R at startup.
I had already tried Cmd-Opt-P-R. Disassembling the RAID and running MainMenu (similar to OnyX) fixed the problem. Seems the partition table may have been goobered somehow, because after I disassembled the RAID, Boot Camp wouldn't touch the drive (even though it supposedly had just an OSX partition and a Windows partition at that point).

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

2010 mac mini server won't sleep

Hi ,
I have seen some people report that there mac mini server running Snow Leopard will not sleep .
I have had this issue for a while and have now installed an App called ' PleaseSleep ' . All seems good and my Mac now goes to sleep so I thought I would let you all know
Best

I was doing some consulting for a client who had Snow Leopard Server on a Mac Mini 2010. By nature a server is not supposed to go to sleep. They wanted the same functionality, which I ended up scripting but looks like PleaseSleep is a better option.
I've searched and saw a lot of people complain about this. Most ended up getting Snow leopard instead of Server which solved their problems. Good find!

Mac Mini Mavericks won't sleep. Why

Processor 2.6 GHz Intel Core i7
OS X 10.9.5 (13F34)
Mini will not sleep either with command from Apple Menu nor opt/com Upper right arrow combo
Energy Saver Settings on 10 minute default

Test after each of the following steps that you haven’t already tried:
Step 1
Take all the steps suggested in this support article. That's the starting point for any further effort to solve the problem. Skipping any of those steps may mean that the problem won't be solved. Note that, as stated in the article, the computer will not sleep if some sharing services are enabled.
Step 2
From the menu bar, select
           ▹ System Preferences ▹ Accessibility ▹ Speakable Items: Off
Step 3
Select
           ▹ System Preferences ▹ Bluetooth ▹ Advanced...
and uncheck both boxes marked
          Open Bluetooth Setup Assistant at startup if...
Step 4
Disconnect all wired peripherals and test. If you use a wired keyboard and/or mouse, use different ones. You must rule out the wired keyboard and mouse as possible causes of the problem.
Step 5
Reset the SMC.
Step 6
Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is much slower to start and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 7
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 8
If sleep is still working after you’ve launched all the usual applications, restart as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after restarting out of safe mode, post again.

I cannot get the new mac mini to wake from sleep and trigger the displays - this is the second mac mini I have had and both have had the same issues. It worked before on my macbook extremely well...

Using 2 displays, connected via HDMI and thunderbolt
Been on to support a number of times now - is anyone experiencing the same issues?

BUMP.
I actually showed this to Apple geniuses when I took my computer to the apple store, and it's still here. In console it says:

I don't know if that's related or not, but maybe helps?

Mac Mini kernel panic during sleep

Hi,
I have a late 2012 MAC MINI that i bought around 3 months ago. Usually my Mac mini is left to sleep/hibernate during the night instead of being shut down. Today morning when i woke up the mini, i saw that a kernel panic had occured.

Does this mean i have to get my Logic Board changed due to malfunction, or is there some other problem? Please assist...
Thanks in advance

No. In fact I wouldn't even worry about it unless this becomes a continuous problem. No software on Earth is perfect. There are, however, some tips you might want to consider:
Some of the backtrace appears that you're running VMWare, and quite honestly I don't know what types of bugs might be present in it.
If you're using a third party drive with third party add-ons and drivers, they can sometimes be problematic.
I know Seagate had software that was problematic with Mountain Lion and they're supposedly putting out updates to fix the problems (might already be done for all I know).
A single crash isn't a big deal. If it's crashing periodically, the it's a problem.

Mac Mini Server won't go to sleep!

Like a naughty child, my Mac Mini server (i7 2Ghz, OS X 10.7.3) won't go to sleep. I use it as a personal computer, not a server, and I like to put it to sleep at night. But about 20 seconds after going to sleep, it wakes up again.
I've shut off all the server functions I can think of, and it's still waking up. Is there any way to determine WHAT is waking it up when I put it to sleep?
Thanks.
David

Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
syslog -k Sender kernel -k Message Req Wake
Post any lines of output that appear below what you entered — the text, please, not a screenshot.
Important: The name of your computer will appear in the output. If that information is private (for example, if the computer name contains your own name), edit it out by search-and-replace in a text editor before posting.

Mac Mini fan won't turn off (only while powered on)

Unlike some stories i've read while crawling around the internet trying to solve MY problem, it's not that my fan won't shut off EVER. The fan shuts down when i put it in sleep mode or shut down the Mini. No problems there. But while the computer is in operation, the fan runs non-stop.
It wasn't always like this. In the 2.5 years i've had my Intel Mac Mini, it has more and more frequently employed the fan. As of the last couple months, the fan is now in continuous use, as long as the computer is in operation. In addition, all the programs take much longer to load, and i'm dealing with programs crashing (Firefox & Safari far more than anything), Bluetooth not functioning, and the front light on my Mini is out.
As for the fan, the Mini is getting plenty of breathing room...even more than it had before the problem. I also have 22GB left on my Mini's hard disk.
Are all these problems related? Am i really just working on my last thruster here? Is my dilitium crystal just about dead? Is a warp core breach imminent? I do not have AppleCare, and i don't know if the Apple Store would look at it for free if i brought it in. Any help (no matter how small) would be greatly appreciated.

When you start your mini from cold (after at least an hour powered down) does the fan spin up to full speed immediately, or does it start out normally and then speed up after a few minutes or so? Did you have the system open for any reason just before this behavior started?
If you had the system open, it might be something as simple as the fan control cable that is not connected. When disconnected, the fan will run at full speed all the time.
It the fan runs at full speed almost immediately from cold, then it would suggest one of two things: either the system is suffering from something like a loose heatsink, or there is an errant process running that is putting the system under heavy load. You can check that by opening Activity Monitor (in Applications>Utilities) at looking to see if the CPU load is consistently high. If it is, look for a process that is causing it.
If the fan runs quietly at first, and then speeds up, after a few minutes, then it does seem likely to be a heating issue. Aside from making sure the vents around the base and on the back are clear by using a good vacuum cleaner, it's possible there is enough debris inside to obstruct the airflow. If you've opened up the system previously for any reason, now might be a good time to do so again, for a quick inspection and clean out.
I would also perform an SMC reset if you have not already done so:
To reset the SMC on an Intel mini:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.
And to ensure you are not suffering from a range of broad 'tuning' type issues, download a copy of YASU (http://jimmitchelldesign.com/projects/yasu/) and run all tasks. This clears cache files, resets logs files, updates prebinding, performs a permission repair and a few other tasks. After the reboot (which will be slower than usual) your system should run a little better.
... i don't know if the Apple Store would look at it for free if i brought it in....
You can make an appointment at the 'genius Bar' of your local Apple store - they will look at your system for free, and help with a diagnosis. What they generally wont do without charging for it is anything that involves opening the system up. However, it's worth paying them a visit for a bit of hands on work!

Mac Mini G4 won't boot; fan full blast . . .

Hello!
I was using my G4 Mac Mini when it decided to re-boot itself, and on start-up, all I heard is 1 loud whrrring sound from the fan, a short pause, followed by continuous whrring sound from the fan going at full blast (very loud!). The screen shows nothing.
I've tried the troubleshooting steps in the Apple site but nothing seems to work. Each time I start it up, it does the same thing.
A few months back I'd the unit repair under warranty by Apple (replaced logic board). So it's quite frustrating to have it down again - and now it's out of warranty.
Any ideas?
Thanks.

It's perhaps telling that the problem occurred after the system forced a reboot. That tends to suggest there's a significant fault - likely hardware, since if the issue was with MacOS it would not be likely to cause the fan to ramp up to full speed on startup with the screen showing nothing.
You mention that you've tried troubleshooting steps, though not which ones. Likely, given that it features in G4 mini troubleshooting of startup issues, that would have included a PMU reset, but if you haven't yet tried that, do so. I would not hold out much hope that it will assist in this situation, but the power manager is the only hardware component that could cause this sort of potential issue, and the only one that can be reset by the user.
Assuming a PMU reset doesn't help at all, and since the system doesn't show any display, it's not worth trying to boot from the original install disk to run the hardware test since the system isn't even managing the power on self test, thus won't move on to loading MacOS. At that point, I'd say you should take the mini to an Apple store if you have one in your location, or to an Apple authorized service provider for them to give you an idea of what is wrong and what it would likely cost to repair it.
If you don't want to do that, the only option is to open the system and examine it yourself. The problem with that, however, is that there really aren't any user-servicable parts inside so other than checking that everything is correctly connected and properly seated, there's really not much else you can do.

Mac Mini WIFI won't connect in 10.6

Hi I have a 2008 Mac mini. I got Snow Leapord and Installed it on my computer soon after it cam out, but there was one problem- it won't connect to WIFI. Other computers work fine in the same room, and my own computer works fine when running windows, but won't connect in 10.6. I have dongraded (or in my case upgraded) to 10.5.8 but am missing some of the fetures of 10.6, is there anyone else with this problem that has found a solution?

Hi Adam,
There's not really anything you can do to reset the chip. What sort of wireless encryption is deployed at your place of work? Is it 802.1x or some other enterprise level security? I've definitely seen some "wonky" things with 802.1x and Snow Leopard, it's what is deployed here at the university I work at and support. If it's something more basic like WPA or WPA/2 or worse... WEP then you can try:
Deleting the saved wireless network location
Creating a new network location
Removing any keychains associated with your credentials for the network
There are ways to "reset" the network software but it's pretty invasive and that's only a last resort. The fact that it works at another location just fine would tell me that there's no hardware/software problem.

Mac mini now won't even turn on

A series of problems started going on with my mac mini intel when I was attempting to burn a DVD:
-I opened disk utility and attempted to burn a DVD (something I've done many times before), only to find the "burn" button was greyed out and it wouldn't allow me to burn anything.
-I inserted a blank DVD only to have the computer spit it out instants later, I inserted it again, and the same thing happened.
-Finiding this really weird, I checked the DVD image I was attempting to burn with the "get info" button on disk utility and found that it was recognizing the archive as being on an external disk, even though it was on the internal.
-I thought there might be a problem with my disk so I verified it, and disk utility told me everything was fine. So I attempted to reapir disk permissions. After about 15 minutes of DU telling me there was "about a minute" left to go, and the status bar going nowhere, I gave up and decided to boot through the mac OS X installation CD (I have 10.5).
-I put the cd in and held "c" and nothing... the computer booted normally. I did it again and nothing. And now I noticed that the computer didn't recognize the disc, and I couldn't even eject it.
-I tried all the solutions presented here for ejecting, including terminal and sticking a business card to loosen it up, nothing worked. I called my father, and he said we had to reset the parameters by reseting the mac and holding ctrlalt+PR and letting it restart 3 times.
-Well... now the mac mini won't even start up... it turns on, but the monitor doesn't even recognize it and no image shows up. It stays like that for as long as you leave it on, so I eventually had to force a shut down, and try again, to no avail. There's a small beeping noise about twice, and then a stronger sound that suggests it's trying to boot, but nothing... and it heats up a lot.
any ideas?

OK, now when I turn it on the light on front doesn't even go on, and it just starts making a loud exhaust noise (like a "vvvvvvvvvvvvvvv"), and the ventilation in the back goes crazy strong... I had to unplug it

Mac Mini Slow & Won't Recognize CDs

A classmate of mine is having issues with his Mac Mini, early 2009 model & was looking for advice. He is curious if there is anything he can try before he takes it to the Apple store as he runs his music business from it.
It's a Mac Mini, March 2009
OS 10.5.8 (he thinks)
C2D 2GHz
1GB RAM
120GB HDD (only 9.5GB free according to him)
nVidia 9400M (128MB shared he thinks, not sure)
He says that he installed VM Ware Fusion on it with a dynamic partition. It seems that the unit runs slower when the VM is not running than when it is. (Yes, I agree that's odd.)
His specific question is 'what free defrag programs exist for mac?' I explained it's not entirely necessary and that might not be his issue.
Also when he attempts to burn CDs the first discs he uses won't read. He'll reboot & it will see the disc fine in Disk Utility & Finder. Once that happens he can burns discs at his leisure (until the next time he reboots without a disc in the drive).
Any advice for him before he brings it in?

I actually talked more to him & one of my coworkers. He said that, in fact, he's got 4GB of RAM as he had it upgraded (after purchase). My class mate said he uses a program called Fruity Loops 9.0 (I've never heard of it) to mix his songs & that it would get choppy when (like a skipping CD) during playback once compiled.
My coworker said that he knows Fruity Loops & says that it's a processor-intensive task. He's only seen it perform well on PCs with dual cores at 2.5GHz & up, or MacBook Pros, Mac Pros, & iMacs with 2.4GHz & up. He also said that the disc drive may need a firmware update as he's seen Mac Minis get flaky without the right update.
Once he's gone through all those suggestions I'll report back.
Thanks Ian!

Mac Mini G4 refuses to sleep due to KVM switcher

I have a KVM switcher + powered USB hub hooked up between my Mac Mini G4 and a PC- while the PC is able to enter standby mode, my Mac always wakes up within 3 seconds of entering sleep mode. Belkin tech support said this is due to the Mac receiving USB signals (albeit me not moving the mouse, touching the keyboard, etc), and told me to ask Apple how to disable this feature.
Ideally, I'd like the computer only to wake up from a keyboard signal, but the powered hub might be making that unfeasible. However, I'm okay with taking the Mac out of sleep mode by pressing the button on its back.
Can anyone tell me how to fix this (as my LCD monitor's output is beginning to suffer)?
Thanks,
Jamie

Hi, Jamie. Welcome to the Discussions.
1. You wrote: "I have a KVM switcher + powered USB hub"It's unclear if you mean:
a. Two separate peripheral devices, i.e. KVM switchbox and a powered USB hub.
b. One peripheral device that performs both functions.1.1. Which is it, (a) or (b)?
1.2. If (b), is the USB hub is connected to each computer, or the KVM switchbox? If the former, try the latter. Don't connect the same USB hub directly two two computers2. You wrote: "Belkin tech support said this is due to the Mac receiving USB signals (albeit me not moving the mouse, touching the keyboard, etc), and told me to ask Apple how to disable this feature."If you make any change to USB devices (power them on or off, connect or disconnect them) on a USB chain that connects to the Mac, then the Mac will wake.
This feature cannot be disabled: it is a function of the circuitry.
If you look at the "USB Ports" section of the "Devices and Ports" chapter of the Mac Mini G4 Developer Note, in the subsection entitled "USB Features" you will see:"Wake Up From Sleep
USB devices can provide a remote wakeup function for the computer. The USB root hub in the computer is set to support remote wakeup whenever a device is attached to or disconnected from the bus. The keyboard that comes with the computer uses this method to wake the computer on a key press.
Connect and Resume
The Intrepid ASIC contains special circuitry that allows the computer to wake from sleep mode on connect, disconnect, and resume events. Compatible USB devices should support the USB-suspend mode defined in the USB specification."Therefore, if you put your Mini to sleep, then connect, disconnect, power-on, or power-off a USB device on any USB chain connected to the Mini, the Mini will wake.
3. It may also be that either the KVM switchbox or USB Hub (whether alone or a combined device) could be defective. I one had a similar problem where I'd put one of my Macs to sleep and it would wake immediately. Turned out to be a bad Belkin USB hub. Removing the hub restored normal sleep function.
Good luck!

Mac mini "Overtemp" signal and sleep received regularly.

mac mini "Overtemp" signal received regularly.
been researching the regular "Overtemp signal" received by my mini (Mac Mini PPC G4/PowerMac 10,1, 1.42GHz, 1G RAM, Tiger 10.4.11) followed by forced sleep since around the time i updated adobe flash a month ago. it goes to sleep whenever i run streaming video or multiple resource-heavy apps. the fan motor seems to top out, wind down and the mini's power light pulsates slowly/softly. if upon waking the mini a video or heavy process is still running, the cpu often sleeps before i can quit any such process.
i tried reverting to an older version of flash to no avail. i have reset both the PMU and PRAM. i've run Disk Utility from the system disk. iStat Pro reports an average of 130°F/55°C. around a year ago i opened, cleaned and upgraded the RAM in my mini in a clean room. can't imagine it could be worse in there than then when the computer functioned fine.
i found out about Narcoleptic Aluminum Powerbook Syndrome, and found a user that had most carefully removed his PB's temperature sensor. is it possible that i have a faulty sensor? bad fan (even though it sounds like it runs clean)? anything else i could potentially fix using iFixit's manuals?
here are my log files:

Is it possible that the air vents have become blocked? One mini owner had a cat that liked to sleep next to the mini, which caused the air vents to get clogged with cat hair.
Do you have any print jobs that haven't completed? OS X can try to reprint, causing CPU to spike. Doesn't sound like the issue here, but worth a check.
Definitely sounds like a flash-related problem. Have you tried ClickToFlash? It can be downloaded here: http://clicktoflash.com/ . I use this on our G4-based systems, including a mini. This may help.

Mac Mini REALLY won't sleep
