Mac Pro :: System Waking Up For No Particular Reason?
Mar 14, 2008
What could be the cause of an '08 Pro waking up for no particularly good reason, and seemingly never going to sleep? Say I'm working or playing on one of my Dells with the Pros slept, at random times I'll hear the Pros wake up. Also despite setting the sleep timer at 2 hours, if I leave the Pros running I never come back to find it slept. I have similar issues under Windows sometimes so I've not been very worried about that, but what concerns me is that it wakes up when I explicitly send it to sleep.
I'm pretty diligent about shutting down apps I'm not using, and really all I'd send the Pros to sleep with is with Office components running. I have no problems with my other previous and current Macs (although the Air is the only other Leopard machine right now) so am a little puzzled. The MX1000's I use on the Pros are holstered when I manually put the machines to sleep and nothing goes near the keyboard.
I doubt it is a hardware issue - I have two at home, and spilled beer over one of them recently (oops) and swapped it out for another more recent one which I brought back home. The first thing I did was to restore the beered Pro's install and I just heard it do the same thing. I'm fairly certain it's some configuration or software problem but I wondered if anyone had any quick answers before I started rooting around for the cause.
I'm on my third MacBook Pro and all three of them keep waking up from sleep mode. I have reformatted and reinstalled the OS each time. I have reset the SMC and the PRAM. Still no resolution. It happened again this morning and I started digging thru the Console logs. I found this.
10/29/08 8:33:11 AM kernel Wake reason = OHC2
Can someone please tell me what the OHC2 code means? I have no idea where to find the documentation on these codes. If I wake my computer up from sleep by pressing the power button, the Wake reason code is PWRB.
i was working on my macbook pro and it shutdown for no reasoned, no warring message. the power cord was more hot than usual. When i restart my computer the time was rest in 2000. i had reprove some only permission. google chrome don't let me surf the web your connection is not private. And i have some stange warring to in safari like it can be fake website.i try to instal Security Update 2011-003 but it tel me you need 10.6.7 to install you can not instal it but i have 10.6.8. Did i have ben hackor my powercord just heat up and my computer just shutdown for security, and have damage some setting that i need to restart. macbook pro, 2.4ghz intel core i5, 8gbmac os 10.6.8

I have a 2009 8 cores 2.66Ghz Mac Pro with 16GB RAM and ATI Radeon HD 4870. It keeps waking up randomly from sleep. I have tried quitting all applications before sleeping, but it still woke up from sleep by itself. Anyone has nay idea why it kept waking up randomly?
I have a Mac Pro 8 core XEON with OSX LION, 22gb Ram, Ati 1gb to conect an Apple Led Cinema 27" anda Apple HD Cinema 23", two hard drives 1tb and 350gb, 2 external hard drives 500 gb, and 1tb. Now frequenly my mac shut down without anyreason, sometimes doesnt start up properly and a i have to restart.Â
What can i do to solve this problem?Â
I have my mac pro and all the other thins conected to an UPS.
ok so i suppose the inevitable had to happen. and so my mac OS X crashed badly within a few days of my getting this new MBP!
i had a short word document open in 1 workspace some firefox tabs in another, and was checking out the movies in my ext HDD (formatted with NTFS).and suddenly i start seeing this multi colored round icon which i guess is the cousin of the windows hourglass. after trying unsuccessfully to force quit, i was forced to hut down using the boot up button. yes, the same procedure that wreaks havoc on the HDD.
- so my questions are - what to do if even force quit doesn't work ? its surprising that it didn't in this case, as i have used ubuntu for almost 3 years and never had the OS crash on me! of course there were a few application crashes but the force quit always worked. and there was the keyboard shortcut - Ctrl+Alt+Del.
- also what is the norm with macs in this regard ? do they crash often and for the flimsiest of reasons as in my case ?
- probably i am not aware of the Mac OS equivalent for the Ctrl+Alt+Del function that almost always works in ubuntu. so is there some key combination that is guaranteed to work in the even that even force quit does not?
I started to notice that my Mac Pro beeps. It is every so often with no rhyme or reason. I first started to notice it when I was booted to XP, but it is also doing it in OS X. I assume it is coming out of the internal speaker.
The first problem, which is what I named the thread for, is that for no reason, while sitting on a desk, doing disk intensive work, the drive clicks fairly loudly and seems to spin down, causing delays. Is it a faulty drive, or can this be fixed via software?
The second may be related to the first. When watching somewhat large movie files (>600mb), the video skips for about 30 seconds every 30 minutes. While this may not seem like much, it is incredibly annoying. Is this because of the speed of the drive, or is it faulty? Coming from a 500gb 7200rpm external for my iMac, I never experienced either of these problems, although I suspect the first has something to do with the motion sensor in the MBP.
Where can I go to find the reason why the system froze up? This is the first time I've had pus the power button and do a hard reset since installing SL a month ago.
Since i've installed Yosemite, I noticed that my fans are always running on high level (6000rpm) for no reason. As soon as I open it the cpu starts overheating (between 195 and 205 degrees) even if there's no apps using significant energy. I already tried to reset the SMC or the PRAM with no results. Â

A few days ago I found that launchd was constantly using around 14% of my CPU (via iStat), which drastically lowered my battery life and caused my CPU to reach 75 degrees Celsius and higher. Initially I thought that SL just needed to do something, so I ignored it. But it has persisted for a few days now, so I decided to do something about it.
I checked the Console and nothing appeared to be repeating itself, so what I did was use MainMenu to perform a batch of system maintenance tasks, and then left my Mac on overnight to see what Console would report. Besides hourly instances of "kernel" running "iCalHelper" and "SubmitDiagInfo", there was nothing else.
However, launchd lowered its CPU usage to about 3%, but it is still constant and my CPU is still at a constant 40-50%. Activity Monitor says the following processes are (constantly) taking only 1-4% of the CPU: coreservicesd launchd mds WindowServer disnoted activitymonitord ...and others The CPU is reported as 35% User and 20% System. But I am not running anything besides Activity Monitor.
But other programs still running fine? On my OSX partition only 4 free gigs left. Could this be the problem? I miss firefox, but alas I'm stuck using chrome.
I have an 08 mbp. Was awesome for about the first yr. Slowly it kept slowing down to the pt where I just open up a browser like chrome and the memory fills up suddenly. I try backing up my very important files so I can reformat it but as soon as I try pasting even a 1 gb file it says memory full. I have 2 gigs and that was more than enough for my use.
For some reason, my menu bar is lagging this morning. I even tried restarting. All I have running are last.fm, Camouflage, LittleSnapper, InsomniaX, and Caffeine. Everything usually runs fine, but right now when I click on them to change the preference, it takes a few seconds for the drop down menu to come up.
I am quite new to Mac and I've had the new 21.5' imac for around a month now and since few days ago, I started getting kernel panics at least once a day.
Recently my computer has been shutting down for no apparent reason. I needed a new battery so I assumed that this was the reason. Now I've replaced my battery but my computer continues to completely shut down.
Lately, my laptop has been freezing for no reason. I've only had it for a year now. Sometimes when I open it to wake it up from sleep, nothing will appear on the screen, but the light indicates that it is on.
My two week old Mac Pro shut downs for no pparent reason. Using the wireless, not plug in to an outlet but battery fully charged. Both times happen within 15hrs. apart.
iTunes LPs have stopped working for me for some reason. It's been like this for months and I haven't found a solution anywhere. When I click on the LP file, nothing happens. Nothing pops up, nada. It's like as if I hadn't clicked on it at all. This is affecting ALL my iTunes LPs. I checked the files in the iTunes media folder and they all seem to be there iTunes just won't open them. I have the latest version of iTunes and I'm using a 2010 iMac 27" running Mac OS X Lion, the latest version.
This is really getting old. Now I want to return the $4000 computer and go back to Microsoft. I've seen discussions dating back to 2007 about Macbooks and iMacs automatically muting themselves with no solution. APPLE FIX THIS NOW. Enough of this problem. Write your OS so that it is IMPOSSIBLE for the iMac to mute itself
Now, before I return this hunk of junk, can you please tell me how to STOP this iMac from muting itself? (In system preferences/sound/output, the Mute box is checked and GRAYED OUT so that it cannot be changed by the ADMINISTRATOR (why on earth would you program it to do that?).
Macbook pro (older style non-unibody) running 10.6.8 has started randomly shutting down instantly for no reason. Sometimes only lasting 30 secs before just shutting off, sometimes up to 10 minutes. Happens when cool or hot, no apparent rhyme or reason. Tried resetting SMC, no difference. Ran software update, thought that had fixed it as it stopped happening for a day, then the problem started up again.
I have a problem with Mail. it crashed everytime i open the application, and i keep on reporting it to apple, and sometimes ignoring that, and nothing changes.
it happened to me before when i try to open a certain email from my friend. now when i open Mail, it automatically opens the first email on the list, and it's another email which has the same problem.
i don't know how to solve this problem.
My laptop is a Macbook pro 2.16ghz core2duo processor, 2gb ram, 160gb harddisk (80 gb free space), Running Leopard 10.5.1.
I just noticed that the fonts of some of the italicized words in a few pdf documents have been changed. This just happened suddenly for no reason. Does that mean my Mac has been hacked or Apple has changed something on the previewer (version 4.1, 469.2.2) which came with Leopard? I also noticed that the wireless network connection has been very slow for the past two days.
My rev C. SSD runs beautifully, for hours and hours, usually without the fan on. Is there any reason for me to upgrade. This is my only computer, and I'm tempted by the old saying: If it ain't broke.
