10.6.7 Update - Fan running loudly

Just updated to 10.6.7 and now the fan is continuously running. Multiple restarts are not resolving. its like the Mac thinks it is hot or something, but it isn't.
Anyone else having this issue?

Apple, please look into this and fix it before it kills my MBP 15" that I really depend on.
Apple does not read these forums, they are manned by end user volunteers people just like yourself. Please do a SMC reset and PRAM reset and if you still have problems post back. You can find instructions below:
_SMC RESET_
• Shut down the computer.
• Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
• On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
• Release all the keys and the power button at the same time.
• Press the power button to turn on the computer.
_PRAM RESET_
• 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
• 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.

Mac Mini fan running loudly after Safari upgrade

Mac Mini 2GHz is around 2 months old. All been fine until yesterday. When running Safari (it seems) and not necessarily heavy usage fan starts runningvery loudly. In the previous 2 months NEVER heard the fan or at least it's been very quiet, so am quite concerned. It appears that this has coincided with updating to the very latest Safari release 3.1.1.
Anyone else having similar problem and/or advice?
thanks
D

The new Safari release supposedly has some issues with Flash media files and with Windows Media files -- and will require updates of the helper programs that display those formats.
Does the fan run loudly when you visit sites with such files? Or does it also run loudly if all you visit is sites with no video files on them?

Will running games that make the fan run loudly and the computer heat up damage my machine?

On my Macbook Air running Yosemite 10.10.3, with 4 GB RAM, 251 GB storage (170 GB free), a 1.6 GHz Intel Core i5 processor, and Intel HD 6000 1536 MB graphics card, when I play games such as Batman Arkham City, I experience very smooth gameplay with high fps. The only thing that worries me is when I play, the laptop heats up very much and the fan runs pretty loudly. Even with old, less intensive games like GTA SA, the computer gets pretty hot and the fan runs loudly. Is this damaging the computer, or can I continue to play these games?
Thanks.

Yes you can continue to play games but heat is the bane of electronics and in time there will be a cost. When is hard to say, but I can put it this way, a fan running constantly at high speed is more likely to fail sooner than one at a slower speed.
Ciao.

No startup chime, red light, fans running loud...

yeah, I know that there are other threads with the same topic, but I just wanted to know how common this problem is?
How many people have experienced this?
What are the common disturbances?
What is going on?
Why is such an expensive, powerhouse computer become such a puny electronic product because of power issues?
I posted this in another thread but,
Here's my story:
I am having the same problem.
Now before you start taking advice to back up all your data, reformat your hard drive, and reinstall all the software; please take note of a few things:
first off, I'm ****** that this is happening to me. I spend $5000+ for a "reliable" Apple computer. Then it doesn't want to turn on because its not safe. Sorry if I drown this post with bitter sarcasm but I am coming to the end of the line with my patience.
I called Apple Care, read a bunch of posts (here and elsewhere), and yes I do know about the SMU Reset button (like that really does anything?).
My problem happened a few weeks ago and I thought nothing of it at first. There was a power outage for a quick second and it turned everything off. When I went to turn on my computer, there was no chime, the red light was on, and the fans were running and eventually began running very loud. After letting it run like that in hopes of the screen lighting up, I turned it off by holding the power button. By the way, there's nothing on the screen and the keyboard doesn't work (I use a wireless keyboard, but I plugged in the OG cord keyboard to push whatever series of buttons recommended by these "geniuses") Trust me, the computer doesn't make it to that part of the boot process, so stop with commandoption+PR or F12 to get the CD out. It doesn't work! What's up with this computer! It can handle all these intense calculations,etc. but a power surge is going to shut it down indefinitely.
So I left the computer came back the next day, turned it on and its fine. Cool, I'm happy. It's Working!! I go on a few weeks, then I go to turn it on this Monday, same problem. But actually a worse situation. I had a client come over and the computer wouldn't work. I looked like a idiot. Couldn't do anything cause my computer didn't want to turn on. I do music production/editing. I use my G5 for running ProTools LE. I have other programs but that is the main one I use. There's nothing wrong with it. It's optimized for use with the mac. So those people who are going to advise me to uninstall all my software and all that - I appreciate your concern but don't give advice when you don't know anything!
So I am getting frustrated. My client left a little disappointed, but what can you do? I tried to call AppleCare on Mon. but it was Memorial Day. So I waited for Tues.
Tues morning, my computer turns on like everything is fine.
I'm happy but cautious. I talk to AppleCare rep. He tells me that it is a common problem they have heard about with the G5's. Wherever blackouts, brownouts, spikes, sags, dips, and other electricity inconsistencies occur, the Power Mac G5 has a breaker in it which flips so it doesn't receive uneven power supply and damage internal components.
I like that feature. Good thinking Apple. Protecting my investment from bad electrical grids. But I don't like the fact my computer has a mind of its own where it decides when it wants to boot or when it wants to sit there and run its fans all loud.
I shut down Tues morn to go to work. I come back in the evening, it doesn't want to boot up. Instead of getting angry trying a bunch of times to turn on/turn off the computer, I leave my house all together and go and have a few drinks. I come home ,don't even look at my computer, and go to bed.
I wake up Wed. morning. Go to turn on my computer. Successful boot. It's running. Okay, I think, I'm going to get down to the problem. I read all the logs, not like I know every piece of info, but just to see what's happening. Everything looks fine. I decide to run the AppleCare CD Tech Tool. It says restart holding down C. I do that. When the gray Apple Logo comes up, all this writing about kernals comes up and it tells me to restart or shutdown. I shutdown and attempt to restart, same problem: no chime, red light on, and fans eventually spin loud. Now the CD is stuck in there. I'm going to take it to the Apple Store tomorrow to if these "geniuses" can figure it out.
(Just a side note: Apple calls them geniuses, but its hard for me to think some disconnected college kid with a bad haircut and questionable social skills knows what's up with the power supply issues of a computer; maybe I'm wrong, but you can run your diagnostics and look at the chart of what to do and all that BUT Apple needs to listen to the people)
I am going to get a UPS (uninteruptable power supply) with a clean sine wave output to curb the issue at my end. It's not my fault I live in a area that receives uneven power output. I live in Los Angeles. Summer is starting up and I think its going to be hot, so blackouts, power dips and sags are inevitable. I just don't understand why Apple hasn't considered this problem and fixed it with something:
A recall to change the power supply, Is it something on the logic board?, are they going to reimburse me for lost income (Ha, yeah right)
I really want to know how many people are having this problem?
From what I've heard, it is a common problem.
So I think we need a common solution.
If its so common, it must be the computer. We are all going to live in different areas where the power may vary. Not all of us have the consistent power flow of 1 Infinite Loop in Cupertino, CA. So if it is such a common problem, Apple needs to fix it.
I can't spend more than five grand on a super duper computer and have it wuss out on some power issues.
Its a loss of income and productivity to me.
I can't have that anymore.
Sometimes my computer turns on, sometimes it doesn't.
I bought my PowerMac G5 in April 2006, its been about a month and a half and I'm having these problems.
Thank you for your time.
If anyone else has been having this problem, I feel for you.
It was been very difficult for me not to curse in this post, but I have tried to extend the same respect to all that use these discussion boards to create dialogue, find help, and create solutions.
LETS FIX IT!

Well, you can see my specs below. I have the same problems as you, just worse. I am also running (as I have my previous systems) on an APC Smart-UPS 2200, and it doesn't solve this problem.
I bought my machine last December. In early March (just 2 days before my 90 days of phone support were up), I woke the computer from sleep to check email; about 5 minutes later it just froze. I had to force it down, but it never even got to the startup chime.
Called Apple, bought Apple Care on the spot, spent about 45 minutes on the phone with two levels of support, and Apple couldn't really diagnose the problem. They decided to send out a replacement logic board, processor unit and power supply for on-site service (I don't have an Apple service center nearby).
Nearly two weeks later the technician arrived with the parts, installed all of them, and - nothing. The system still exhibited the same symptoms as before the repair. He spent around five hours here, most of it on the phone with Apple. They decided that the processor unit they shipped was defective, so they sent another processor unit.
Nearly another two weeks later, the re-replacement processor unit arrived with the tech. He installed it, and everything worked. This was around April 1.
Fast forward to last Wednesday. Arrived home from work, tried to wake the Mac. Nothing happened. Had to force the machine off. Never booted again. Called Apple and went through the motions again. They're sending another logic board, processor unit, and power supply.
I asked about having the machine replaced since this will be the third repair attempt, considering it took two visits and nearly a month to repair it the first time it died. Apple was unwilling to replace it but I was told that if I had another failure, a replacement would be in the cards.
I agree with you about needing reliability in a computer as expensive as a Power Mac. It is not acceptable to have this kind of failure, repeatedly, with this kind of system. If my Windows PC has a hardware failure, I can take care of it myself. A top-end power supply is ~$200, a quality system board is ~$200-$300 - all very doable, and in very little time, if the need arises. A Power Mac logic board is ~$1K, a cpu module is well over $1K, who knows how much that crappy power supply costs, etc. If you have Apple Care, you face the kinds of downtime I'm having to deal with. A month without use of your computer. I mean, if I buy a Dell workstation, or an HP workstation, and pay an extra $200-$300 for service and something fails, Unisys will be here the next day and it will be fixed. That's the standard business class service experience you get from those companies with a computer that costs $600, much less the $3000+ you dish out for a Quad Power Mac. Apple's response is unacceptable.
It's a good thing I have kept my Windoze machine around, cause it's really saved my butt the last 2-3 months; that also makes me really sad, because in the last 6-7 years of Power Mac ownership I've had zero problems with any of them. My dad has my previous machine, a Rev A Dual 2.0 G5, and it's rock solid.
I sure hope that the Intel based Power Mac replacement doesn't suffer from what ever seems to afflict the recent Power Macs. I would absolutely hate to abandon OSX, but I will not put up with this kind of quality failure (hardware & service) again.

Finder makes fan run loudly and continuously.

I've had my MacBook for only a few months now and I am having a problem with the fan. It starts running loudly when I am doing simple tasks, such as viewing a webpage which contains no flash, video, or similar content. The fan does not stop running unless I put my computer to sleep or restart it. I have found that by relaunching the Finder, the fan almost instantly slows down back to its normal state. This concerns me as this has been occuring more frequently over the past two weeks. Is there some sort of fix to this instead of having to relaunch the Finder every time?

Yes you can continue to play games but heat is the bane of electronics and in time there will be a cost. When is hard to say, but I can put it this way, a fan running constantly at high speed is more likely to fail sooner than one at a slower speed.
Ciao.

Is it bad to have the fan running loud all the time

the fan on my macbook runs loud and long at times. is this bad for the machine?

Is it possible to have 2 threads running at the same
time at different times eg 1 repeats every 20
miliseconds and the other 40 for example. Yes.

MBP battery crapped out, now fan running loudly

While I am waiting for my replacement MBP battery (which I ordered yesterday) it looks like my current battery finally crapped out, as my computer shut down again automatically last night while I was on a plane and I'm getting a big "X" where the battery charge indicator is located. This appears to have caused my fan to run at a higher rate or something of that nature because the fan is now very constant and loud. Everything else on the computer seems to be working fine however, so long as I am plugged in. The question is, is it OK to be using the MBP with the fan running like this until the replacement battery comes in, or should I try to change to setting on the fan? And when I get the new battery in, will THAT make the fan go back to normal?

I do think it's normal. Keep in mind that batteries vary - the "health" is determined with a nominal value as the denominator (5500 mAh for a 15" MBP, which is actually rounded down from the calculated full charge capacity of a new battery, 5555 mAh), but the actual full charge capacity of a new battery varies within a range around that nominal value. So, if you happen to get a battery with a full charge capacity higher than 5500 mAh, iStat or CoconutBattery will report your health as 100% for some time, even though the full charge capacity is dropping - you started from >100%, but the utilities will just show 100%, not a value like 107% even if your battery started with a capacity of 5900 mAh.
The bottom line is that a rechargeable battery starts with a certain capacity, and over time that capacity can only decrease. The decrease is non-linear, and how rapidly it decreases is influenced by a variety of conditions (charging pattern, temperature, etc.).

G5 won't wake from autosleep, fan runs loudly, ever since Leopard install

I recently installed Mac OS X v10.5.0 Leopard and 10.5.1 update on my G5. Sometimes when the computer puts itself to sleep the G5 fan starts running full out and does not seem to stop. Usually I am able to wake the computer up from sleep just by moving the mouse or pressing any key. But when the fan starts running hard I am not able to get the computer to wake up again.
Energy Saver settings are one hour for computer, 15 minutes for display, and "Put hard disks to sleep..." is checked. The problem does not arise when the screen goes to sleep or when the hard drive rests, only when the computer itself goes to sleep and then only occasionally.
This problem did not occur ever under v10.4.11 or earlier. In fact I hardly ever hear the fan running. Thus I am suspicious that it is somehow related to the Leopard install.
I have noticed other posts similar to mine, but no apparent solutions. Some posts mentioned a Logitech mouse upgrade being necessary but I am using a Microsoft 3000 Wireless Optical Mouse and no software is needed for it to function.

Any time you have power management or sleep/wake problems, a good first step is to reset the low level controller that handles that stuff in your Mac. For intel-based Macs this is the SMC. For Power-PC based Macs this is the PMU.
Go to the main Support page here and, in the search field at the top LEFT of that page, search for "reset SMC" or "reset PMU" as is appropriate. In the list of Knowledge Base articles returned, find the instructions specific to your model of Mac. It is not hard to do in any case, but you do need to find the right instructions for your Mac. Note that resetting a PMU will likely require you to manually correct the Date and Time (System Preferences / Date & Time) the next time you log in.
While you are at, also reset Parameter memory (PRAM). PRAM holds copies of certain system settings for rapid access, and if it gets out of whack all sorts of odd things can happen. The instructions for resetting PRAM are the same for all Macs. Shut Down the computer. Locate the 4 keys Apple-Option-P-R. Press and hold all 4 of those keys and, while doing so, press and release the power button. Keep those 4 keys held down until you hear the SECOND startup chime, then release them. Your computer will continue to boot up normally.
Once you log in, go to Applications / Utilities / Disk Utility. Select the line in the column on the left showing the name of your main hard drive. Then click on Verify Disk in the panel on the right. Be patient, this will take a while and the progress bar may not advance until the very end. If Verify Disk finds any problems you will need to boot directly from your Leopard Install DVD (hold the "c" key while booting and insert the disk shortly after pressing and releasing the power button) and, instead of proceeding with a new intall, run Disk Utility from the menu bar. Once again select you main hard drive, but this time do a Repair Disk.
Once Verify or Repair Disk shows no problems, go back to Disk Utility while booted from your main hard drive (if necessary) and this time do a Repair Disk Permissions. Once again, be patient. This will take a while (20 minutes or so) and the progress bar may not advance until the very end. This may produce a variety of messages, but if it finishes with "Permissions Repair Complete" you are good to go.
Now Restart the computer and, once logged in, run Applications / Disk Utility / Console. Select "All Messages" in the column on the left. If this is the first time you've done this, Console will take a while getting organized -- initially the message list may be empty.
Now try commanding your computer to Sleep and then Wake from sleep. Check the Console messages to see if any problems are reported.

Apple macbook won't boot up and only fans running loud

Hi,
I am having a big problem in my laptop, it's not display anything, and when i press on power button only fans running aloud, and the charger, battery working!
please help me!

Unfortunately, we do not have an agent or a local Apple store.
do you help me identify the problem exactly?
thanks

Imac randomly freezes fan runs loud

Hello,
My imac g5 randomly freezes. When it does freeze the fan kicks in and is very loud. This is a stock g5 Imac with no new software loaded. The only applications run on this machine so far are safari, and Mail. Does anyone have a clue as to what could be wrong? I've had the machine for 2 months and it has run fine untill the last week of random freezes. Also does anyone know apples policy regarding replacement or repair? I do have applecare. any advice would be appreciated, thanks,
Dan

Hi,
I have exactly the same problem. I've had it for a couple of months now. My iMac G5 (iSight) is only a couple of months old - I got one of the last ones just after the intel came out. The freeze occured loads with 10.4.6. I've just had it again with 10.4.7 - my first time since I updated with the full combined installer a few days back.
I regularly repair permissions. I have run fsck from single user mode. I have run apple hardware test - no faults. I have checked/repaired the disk from the install disk - no faults. I have removed all external devices - I previously suspected it might be a USB hub causing the problem but no. I have not removed additional ram as yet - that is my next step though it pains me to be doing such things when I bought the computer from Apple and you would think they would have installed Apple approved/top quality ram.
It is very weird behaviour. Never experienced it in all my mac owning days - and I've got/had a few. I had hoped it was a combination of 10.4.6 and the iMac G5 (iSight)... but the latest update has not fixed the problem. And I find it hard to believe it may be the RAM. Because surely RAM just doesn't fail that often?!? And like this?
Any suggestions would be much appreciated.

Yosemite update - fan running constantly

Hi
I have a macbook pro retina - less than a year old. Has been working great, but right after updating to Yosemite - the fan began running constantly on high. It doesn't stop even during sleep (only when shutting down the computer completely). I am not a computer expert - but I did reset the SCM and PRAM and nothing helped. I looked at the CPU, and one thing I noticed is that everything seems to use low percentage, except idling %, which is constantly on 80-99%. Any suggestion on what this might be about, and how to fix it? I'm worried about my

Fan runs LOUD

Hi there,
I bought my first iMac just a few weeks ago, and I am having so many issues with it like I never had with my Windows PC. I'm ready to return the iMac to the store. The latest thing that started yesterday is that the fan comes on as soon as I turn on the iMac, and it runs so loud, it is hard to listen to music or just sit in front of it. I have almost nothing running, and it starts without any reason at all. I sent it to sleep, shut it down completely, pulled the cord and plugged it back in half an hour later, and the fan still comes on as soon as I turn it back on.
Can somebody please help me? I took my iMac to the store today but because of the iPhone pre launch they could not help me at all!!!!
Should I just return it and give up on my Apple experience?

Reset the SMC, following these steps:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
This can fix a situation where the fan is on when there aren't programs driving the systems usage.
When the fan is on high, you can verify that there's not some program driving your systems usage by loading the Activity Monitor, which is on your hard drive in applications/utilities. Look at the CPU tab to see if some program is pushing the CPU utilization high. If you've downloaded any drivers or software, that may be causing the problem too.
I have a couple of month old iMac, and can tell you that you shouldn't be hearing the fan. Oh, one other condition could cause that, if the hard drive was replaced with a non-Apple specific hard drive or if the hard drive is unplugged, which could happen if someone installed an SSD drive (not counting the online store SSD that you can get in a build to order iMac).

Fan runs loudly and upgrades

So mac isn't really famous for having upgradeable products, but is there anyway or anywhere where I can change out hardware on my imac? I have a 20" G5 and I use it for Photoshop and Z brush and it works fine for that, but if I play a game the game play tends to jump. I'm not great with computers and I'm new to mac so I don't know if or where I can change the graphics or video card.
Also, the fan seems to run really loud at times? Does is seem this way with anyones else? It's done this before and I had to get the power supply changed... twice.

See if the following Knowledge Base Article is of any help:

Fan runs loud and continuously

Hi- The fan on my Macbook 2.1 Intel Core 2 Duo 2.16 GHz runs continuously and loudly from about 3 minutes after booting up. Activity monitor shows nothing unusual, only Firefox and Activity Monitor using any CPU (very small percentages). It has been a noisy fan for awhile, but used to come on only after prolonged use. Any suggestions will be welcomed. Thanks -Howard

If you have not already done so....reset the SMC....

Why is my fan running loudly?

My Macbook Pro Retina 13" is about 6 months old. Just today it started running warmer than normal and the fan is MUCH more audible than usual. My office staff commented that it sounds like it's overheating. I am not doing anything differently than normal nor have I downloaded any new programs in the last few weeks. Any ideas about why this has suddenly become an issue? This issue occurs whether the laptop is plugged into my Thunderbolt display or running off of battery power.

Thank you! I stopped the application that had 'taken over' or run away but it was the Mail program and I don't know how to figure out what's wrong with it so that it doesn't happen again.
