Occasionally, my Mac Pro's (8-core early 2008) fans will go to full speed after a shut down. I did the procedure of unplugging everything and letting it sit for 15 mins, and that seemed to work for a day or 2...but last night the problem was back. The only solution is to hold down the power switch for 10 seconds. I just reset PRAM -- we'll see if that has any effect.
View 24 RepliesI have a G5 that is about 5 years old. For some reason it will not sleep or shutdown. When I try to do either one of those actions it does simi-sleep/shut down, but not completely. By that I mean it sounds like the hard drive spins down but then fans still are running. After about two minutes the fans spin way up and the Mac won't start back up. I have to pull the power on my battery backup. I took it to the shop (Not an apple store) and they reinstalled the OS for me and put some new ram in. Supposedly they "Fixed' the problem.

It's a 2.0 GHz dual-processor with 8x AGP video. I checked it out and the only thing "wrong" with it is that someone has set up the fans, all of them, to run full-speed all the time.First, how did they most likely do that and, second, how can I return the fans to their normal operation. This can't be good for the computer and it's so loud and annoying that I'd rather use my G4.It's a great computer otherwise, I hope they didn't do something permanent that would require a new motherboard, that's not in my budget.
I've got this weird problem with my late 07 SR 17'' MBP, after I plug in the Magsafe charger the fans start spining and in like 3 minutes they reach 6000 rpm (both of them) and stay that way until it's finishing the charge. I did the same exact tasks with my laptop charged and plugged in, and the fans stay around 2000 rpm, as opposed to when it's charging staying at full speed.

I can't hear people on the telephone. And never stop. Let me reiterate that I am running NO apps. My load averages are in the zeros.

My menu icons kept flashing on and off for a while. I left the computer by itself for a bit and returned to find the fans blowing at full blast and the cursor wouldn't move. So I pressed the power button to turn off the computer and restarted
My console log showed this repeated about every 30 seconds for about 30 mins
I think the icon flashing was a result of having a film dvd in an external drive like in this thread [URL]
I've ejected a film DVD that was in a Lacie external drive and verified my internal and external hard drives to check for any errors. All were ok.
I'm not too worried about the menu icons flashing but I am bother about the fans blowing like this. The fans have blown at full blast and crashed the computer about 12 times in the last 4 months when I have been away from the computer. So i'm a bit bothered about leaving the G5 alone. I haven't been able to replicate this fan issue - its random. Erasing the HD and installing Leopard doesn't seem to have stopped if from happening (I had the same problem in Tiger)
I have attached a screen capture of my Stat widget below
The slots and backside fans are always stuck at 76rpm and 51rpm. Also CPU A is normally at a high temperature than CPU B. I think the highest i've seen that temperature at has been about 75 but i don't look at it often. These stats were just when I was importing a CD into itunes fans were quietish.
I'm thinking about getting Apple to have a look at my G5 while the Applecare is still valid (it should run out in May).
Can anyone look at their Stats and see if their slot and backside speeds are stuck at similar rpms.
I've got a little problem with my iMac 24" 2.8 GHz Nvidia Geforce 8800GS 500GB. When I start it up, the fans start blowing at full speed. I checked the apple support page for support and found my problem with all the symptoms being correct. The support said I had to reset the SMC by shutting down the iMac, then removing the power cord and all the other one's, wait 15 seconds and then put the power cord and the other one's in respectively. I did this almost 10 times, but my iMac still won't stop making those annoying noises. Maybe it has to do with the SMC fancontrol app my brother installed lately.

Tried every mac temp. software. Looked in activity monitor, nothing major running, biggest thing is "activity monitor". I can just have it sitting on my counter, on hard surface, very hot fans full blast. Its a new MacBook White early 2009.

Is there any way to set the fan speed manually, say in openfirmware?
It's a 1.8 DP June '04; I've ran ASD 2.5.8 to calibrate and test the mobo, which passed.
My Mac OS X as soon as I turn it on the fan is running. I have already gone thru the reset SMC . Could I have too much stuff in it?

I have a 1.8Ghz dual processor G5, 1GB Ram, 80GB HDD, with OS X 10.4.7 installed and all current updates, and today I was working on it and the fans on it slowly started speeding up, and then everything on the screen disappeared and a mesage appeared stating that a restart was required. After restarting everything seems to be working fine, but I'd like to know if this is a fluke or if I have a serious problem.
View 12 Replies View RelatedI have a 24" mid-2009 iMac, bought in June. It's behaving oddly over the past week or so. It fails to wake on sleep on the first attempt, but always succeeds on the second. When I say fails though, I mean that it *does* wake up, but goes back to sleep again after a few seconds. The other issue happened today, when I woke it up, in a cold room, the fans started up at full speed (I assume). It sounded terrifying to me as my iMac has never got that loud - not even playing games. I restarted it and it was the same, but died down after a while.
View 3 Replies View RelatedExactly the same issue on Macbook Air and new iMac both running Safari 5.1 and Lion 10.7.3Â
When I open Safari it does not open a page, it just shows a spinning beach ball and shortly after the fans kick in and the activity monitor shows 1 webprocess at 99 - 100% or sometimes 2 web processes at 50/50% all coming from the User. When I inspect the process it says it's "Parent Process (Safari 450)"Â
When I quit safari the web processes stay at 100% and will only stop when I quit them in activity monitor. I have reset Safari but no joy. Firefox etc works fine. The only update I ran was a 1Password update but they say it's not them.Â
I have a white MacBook and its three years old. It all of a sudden crashed last night and when I switched it back on the fans were running full, the time set to 1-1-2001 12:00am and there is an X through the battery sign. When I click on the battery charge symbol it says " No Batteries Available" although it clearly does as it runs without needing a charger. And then there’s the fan.
It started running at full speed (like I was playing a game or something) and it just runs like that all the time. I have restarted my computer and shut it down several times and the only problem fixed is the time. Also when the screen is shut it doesn’t go to sleep or even show signs that the lid is shut? I haven’t done anything to dislodge the sensor so I don’t know what the problem is.
So today I opened up my MBP to clean it out and stuff (it had a ton of dust... A wall of it had built up where the fans blow out)All is fine and dandy now except for one thing. Since I don't want to open my case up for the second time today (right fan wasn't plugged in all the way first time I started it up... oops x( ) I'm asking here since everything else seems to be fine.
What I did:
Opened everything up all the way down to the heatsink.Applied correct amount of Thermal paste.plugged everything back in (right fan wasn't perfect at first, but fixed and stupidly didn't double check everything else while I was in there)
And now both fans are running at 6k (full) constantly. I tried resetting PRAM and SMC with no luck. I'm about to grab my disk 1 and run the diagnosis to see if that turns up anything.Are there any plugs that I might have accidentally not plugged in all the way or at all that would cause this? Also any other suggestions if everything is plugged in correctly?

Also, I have iStat Menu. No apps using all my CPU (Mostly <10% usage right now) and temp is mostly <40c right now. All temps have a temperature so I'm assuming all heat sensors are fine.On a great note: My computer is so much cooler now! Even before this at 6k rpm I'd get down to MAYBE 45c if I was lucky.I also have Fan Control installed and it's not having any effect
I just bought a new dual 2.0 ghz power mac G5 about 2 weeks ago. I set everything up and dowloaded all the updates for everything, and then about a week into using it the problem started. I left for work and when I got home that evening after the computer had been asleep all day, it sounded like the computer was taking off from a runway. It would not respond at all to the keyboard or mouse so I had to shut it down by holding the power button on the front of the unit and then start it back up. I called tech support but they had me turn the option off that puts the harddrive to sleep when possible and then turn off my screensaver. Well it was fine again for about a week and then it happened agin yesterday, not once but twice. I looked on apple discussion boards and there is alot of this happening. Well I took one guy's advice that seemed to know what he was talking about. I restarted holding the command-option-o-f keys down, then prompted the computer to reset the v-ram, and two other things he suggested to reset that I cannot remember. Then I restarted, trashed the energy saver prefs and ran a repair disk permissions task inside OSX. Well that is where I am now, and it has not done it again, but I am still trying to find out what exactly is going on here. I just spent $2000 on a machine and it appears messed up and Mac has no answer.
View 5 Replies View RelatedSo Ive got the new aluminum MBP and got an incase shell for it. For the first few months I would open my screen and at about 90 degrees it would feel like it was about at the stopping point so I left it there, like the older ones.
I recently let a friend use it and not being familiar with the product he forced it a bit further before I could leap across the room and stop him, I heard a bit of a creak and it ended up going all the way back, as far as it would without a case. Everything seems to be in place but it really did sound like something broke, and I couldnt do this before without force. Is this normal?
I am trying to find a good quality webcam to use for videoconferencing with my Mac (MacBook Air actually). The camera is to be positioned on the 60-inch screen on the wall in our boardroom so the built-in Facetime camera doesn't do the job. It needs to have tilt/pan/zoom (in software). When I started on this search I had no idea such a thing was going to be so hard to find. There is no shortage of such products for Windows but I can't find a single one for the Mac.
There are a lot of webcams that claim to support Mac but on closer investigation not a single one of them (that I've found so far anyhow) provides any control features like tilt / pan / zoom - nor even brightness and contrast control for that matter. Maybe I'm looking in the wrong places because it's hard to believe the Mac world really is lacking such products.

the other day i wake up and open my macbook pro and immediately heard the fan making noises ive never heard it make before. i checked istat pro. the fans were going at 2000rpm. this is when i started to get concerned since i would never hear the fans at that speed before. the difference was day and night. it sounds like the one or both of the fans are hitting something. i always hear the noise when i start up or wake up from sleep and after a while (30 minutes to an hour) it usually goes away but has come back once without me turning off or putting the computer to sleep. its a refurbished less than a little more than a month ago. im hoping its just some dirt that made it through keyboard and will eventually go away because i dont want to send my machine in to get manhandled by apple repair. has anyone had something like this happen before?

My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?
I was just wondering if a full system restore can be harmful or if it's good to do every once in a while to get that "fresh" computer feeling. I just re-installed OSX and everything feels like new but was just wondering if this is bad for the hard drive or something.
View 4 Replies View RelatedWhen I have my brightness at a certain setting and then start playing a game, the brightness jumps to full. When I then press the button for less brightness, it jumps immediately to the setting it was originally.
This also happens whenever I do alt+tab to return to the desktop. So it appears it happens when I do something that requires to switch to full screen mode cause it also happens with other programs.
At normal use, surfing, office,... this problem does not occur. And also it doesn't happen under OS X

Lately my computer has been rediculously slow with everything, but aside from that my issue is with my start up disc. I would have over 1.5 GB of space left, open up a photoshop file...make some alterations and save...and all of a sudden I have NO SPACE left. These alterations created the photoshop file to be like 50mb more. Its a 200mb file. So how can I go from 1.5 gigs to saving a 200mb .psd file and all of a sudden 0 hd space?Â
Sometimes I couldnt even save the .psd because when I opened it all of a sudden I have half a gig now. And even if I had half a gig why wouldnt I be able to save? I go to save and sometimes it says "your start up disc us full" - Is this different than my harddrive?Â
Is photoshop using some sort of weird caching thing?
