IMac :: Fan Runs Loudly With Excessive Rpm's?

Jan 17, 2010

I have been battling with fan speed on my iMac recently.

I installed iStat which shows normal temps, but the fan revs up to 4000rpm - for seemingly no reason at all. Sometimes its quiet for long periods. It sometimes helps for a while if I put the machine into Sleep mode, but then I hear the fan start to rev up again when I resume activity.

I have spent hours with tech support, who then upgraded me to a higher level of tech support. But still the problem continues.

PowerPC :: IMac G5 Overheating - Fan Starts Spinning Loudly

Apr 3, 2010

I have an iMac G5 that is starting up, then working okay for 1-2 minutes. After that, the processor usage goes way up, and the fans start spinning loudly. It's a first generation 1.8 GHz with a 17" display. Mac OS X Leopard. Recently, it spun up and then shut down and wouldn't start again. The room it's in is < 75 degrees F. No malodor, or other symptoms save for hot to the touch. Has been left shut off and unplugged for a few hours, and still has this problem.

IMac :: Google Desktop Using Excessive CPU Time

Jan 14, 2009

I bought my current imac in late 07, I have the 2.0 20" with 1GB ram (don't know why I have upgraded) anyway, it seemed my mac was getting slower over time and I didn't really think anything of it. Its my first mac and I figured it was just like a PC in that hardware wares out. But the problem with the slowness wasn't the mac, it was GOOGLE! I downloaded google desktop about 2 months after i got the mac and its been on ever since. I rarely ever used it, only when spotlight failed to do a good enough job. So I finally opened up activity monitor to look at my ram usage (I am thinking about upping) with all these apps open (FCP, PS, etc) and I notice my cpu is being 50% used.

So I change to view all apps and it appears googledesktopdae and MDS (spotlight) were using 20-30% of my cpu! I finally got rid of it after reading a bunch of forums. Apparently even if you uninstall GD, its process google desktop still stays on your mac and runs. Anyway I don't know how much it has been using while I didn't even realize but in the last 45 minutes since I fully got it removed my computer has been a "screamer!" Does anyone else have this installed? is it using much of your CPU? BTW to fully remove it follow these steps:

1. Delete the google desktop like you normally do any other program

2: add these files to your trashcan:
/Library/Google: delete entire folder
/Library/Internet Plug-Ins: delete GoogleGadget.webplugin and GoogleOneClikPluginDeluxe.plugin
/Library/LaunchAgents: delete
/Library/LaunchDaemons: delete,, and

3. Then STOP the fallowing processes:

Then you can permanently delete the google files. Note that you must top the above processes before you empty your trashcan or else your mac wont let you permanently delete them.

IMac :: Excessive Hard Drive Noise Even With No Activity

Nov 16, 2009

I am getting HD noise like every 20 seconds. Even with no activity. Per the suggestions of another user, I typed this in terminal: iostat -w 1 disk0
And the sound seems to coincide with the output whenever the first column has a value other than 0. So it seems there is activity, it's just not user initiated. Is this some kind of energy saving feature that apple is doing or is it a logging application? Is anyone else having the same issues? Even if you're not, could you run the program and check for 1 or 2 minutes (without any other apps open or doing anything) to see if you also get a value other than 0 in the first column every so often and an associated sound?

OS X Mavericks :: Excessive Unauthorized Remote Access Attempts On IMac

Sep 5, 2014

This morning and throughout the day this is how my console looked:

 My machine became unresponsive at times up to the point that I had to hard-restart it twice. Before today I hadn't noticed any weird activity like this, I looked up some of the ip addresses that appeared there and all of them were marked as malicious ip's. 

Is there anything I can do to prevent this other than shutting down the vnc access? Is logmein a better/safer option? I need to connect to my machine remotely almost on a daily basis. 

Why this started happening to my machine all of the sudden? is not like I keep highly classified info on that computer, is a common occurrence and I shouldn't worry? All the attempts are failed, but it got to a point where I'm getting more than one per second, so I guess that's what caused my machine to crash.

PowerPC :: IMac Runs Slower Than G4?

Jun 28, 2007

Just got an Intel iMac, with 1.5g ram (one 1g and a 512mb). I've been running CS2, and have been very disappointed. Previously, I was using a G4. I was expecting the program to run faster, even under Rosetta, but not only has it been slower, InDesign is acting buggy, with crashes, and corrupting files.

I'm going to get a second 1G stick of ram to see if it's a matched ram issue, but I'm interested if anyone else has had this problem.

IMac G5 Would Not Start When New RAM Installed / But Fan Runs

Mar 21, 2012

I recently upgraded the RAM on my iMac PowerPC, but after installing the new modules, nothing would come up when I boot it. It gives me 2 (or three) of the "dial tone" beeps, the light flashes on and off and the only thing running would be the fan, running at an ultra high speed.I did install the correct modules, which are 2 x 1gb 184 pin DDR PC3200 400mhz ones, but I realize that they are high density ones. Dumb question here, but would that be the problem?

IMac (Intel) :: Fan Runs Full Speed On Shut Down

Aug 27, 2014

My iMac runs perfectly fine; more or less as it did when it was new. In OS X, when I shut down the computer, the fan runs at full speed indefinitely, unless I unplug it or boot back up.  When running, the fan is perfectly normal (increases speed a bit when doing something taxing).  I've never heard it at full speed before until this started happening.  After following the SMC reset procedure with no luck (I'd like to add that the SMC reset only says it relates to fan problems when the computer is ON), I searched a bit and noticed there are one or two cases where a problem like mine was believed to be a motherboard issue, and therefore a costly fix. 

However, here's the fun part. When booted into Windows 8.1, shutting down the iMac does not cause this issue to occur.  It stays silent, as it should, even if I disconnect then reconnect the power.  This leads me to believe it's unlikely to be a motherboard issue.  However I've wiped, restored, and reinstalled fresh copies of Mountain Lion, Mavericks, and Windows 8.1, and the result is still the same: if I don't want to have to unplug it from the wall, then I have to use Windows to shut it down. 

So then, my questions are these:

-What is the difference between shutting down from OS X and shutting down from Windows?

-Is an operating system allowed/able to touch BIOS settings?

-Is it possible to still be a hardware problem, given this difference? 

My default OS is OS X, and it makes no difference if I change that to Windows.  I also did a PRAM reset, even though that has nothing to do with fans...

IMac :: 17" 1.83Ghz Core2Duo (MA710LL) - Runs Beautifully?

Jul 31, 2009

I purchased a Refurb 17" iMac 1.83Ghz Core 2. It would have been the Education Model for what I gather. No Bluetooth, Combo Drive, no 802.11n wifi, and Intel GMA950 graphics. Apple Specs state max RAM = 2Gb (2x1Gb). Has anyone been successful with trying 4Gb (2x2Gb)? I ask because we also have a Black MacBook (MA701LL/A) and Apple Specs state max RAM is also 2Gb, and we have had 4Gb in it, and runs beautifully!

OS X V10.7 Lion :: Brand New IMac Runs A Disk Check On Start Up?

Feb 16, 2012

I've owned this iMac for less then 20 hours  

Mac OSX 10.7.3
2.5 GHz Intel Core i5    
4 GB 1333 MHz DDR3 ram
"Mid 2011" 

It was purchased brand new. I used it for one hour yesterday, run the set up, install updates. thats all I have done with it. Today I awake to it presenting a loading bar of some sort under the Apple logo and Spinning wheel. I researched the bar, and found that it was a progress bar for a disk check, and since it doesnt complete (I let it do its thing) something must be wrong, However when i run disk utility, it can find now error in the disk. but my sound and video play pack does not work unless i restart the machine. this seems like an unessecary process. what are the possible causes?

MacBook Pro :: Does Not Fully Wake Up - Fan Blowing Loudly

Feb 16, 2012

Recently I have woken up during the night because my Macbook has randomly 'awoken' causing my two external hard drives to spin up and its internal system fan to start blowing loudly. This is weird for a start. What's weirder is that it doesn't fully wake up when it does this, or at least my external display doesn't come on, it just sits there in this half awake/half asleep state with the fan blowing a gale.If it's doing something weird like waking on LAN or Bluetooth or one of my iDevices trying to sync etc, is there a way to disable this or at the very least kill the noisy fan?

This problem typically occured when I was doing something particularly strenuous, but I just recently had it happen while browsing the internet. The computer will suddenly freeze and start beeping loudly in groups of three with an LED on the front flashing in sync with the sound.

MacBook Air :: Excessive Water Damage?

May 7, 2012

My MacBook Air was not starting up so I sent it in for a repair. Just got a call that the logic board is corroded and there is excessive water damage. However, I have never split anything on my laptop nor has anyone else. I carry it around with me all the time. I thought at first it might be damage due to a shock as a dropped it a few months ago and it has a slight dent on a corner.

Software :: Mac Mail - Excessive Incoming Messages

Sep 8, 2009

I use Mac Mail at home and at work. At home everything works fine. At work, in general everything is working, but every time I start up Mail, it says there are over 1500 Incoming Messages and proceeds to "download" them. Of course there aren't these messages. My two email accounts are .Mac IMAP account and a business IMAP account. These 1500 messages don't seem to be put anywhere, and I can't seem to figure out which account these messages are coming from. The problem is downloading all of this makes my computer slow down a bunch (old mac) and it takes a long time. The problem does not affect my home Mac or my iPhone.

OS X :: Excessive Data Time Machine Backups?

Oct 8, 2009

I have my Time Machine hooked up to a Time Capsule and it seems that Time Machine is backing up an excessive amount of data throughout the day. Normally the backups are just 5-10 MB, however it seems that once or twice a day it backs up 2-3 GB worth of data. I don't do much saving/creating/modifying of files during the day. just web-based programs, iTunes (no downloads), etc.

MacBook Pro :: Excessive Wired Memory Usage?

Feb 17, 2012

I have a 2010 MacBook Pro with an 2.66 GHz i7 processor, 8 G-Byte of RAM and a 500 G-Byte hard drive with plenty of free space and am running OS X 10.7.3 . Whenever I run a Windows 7 Pro virtual machine under Parallels 7, ~ 6 G-Byte of wired memory is used. I have allocated 4 G-Byte of memory to the virtual machine. I would expect plenty of free space and that used to be the case but no longer. I am tired of an unresponsive machine and spinning beach-balls.

Sep 11, 2014

About month or two ago, I started getting excessive ads on my computer. Scams, Microsoft stuff, Adobe Flash upgrades hat were obviously fake. The ads generally appeared on the pay, but evolved to gene ate separate tabs and windows. It gets really annoying when i can't click twice without getting a scam, or being redirected. I don't know if there are similar topics. i'm not going to look cause in the 5 minutes it took for me to write this, I've been redirected TWICE.

Software :: Why Need Excessive HDD Space To Import Photos To IPhoto

Sep 18, 2010

I've been trying unsuccessfully to import 8gb worth of photos directly from my DSLR (a Canon 40D with CF card) to iPhoto and it keeps telling me I've run out of HD space before it's finished even though I've over 15gb to start with. I tried again tonight after freeing my HD up to 29 gb and it got to about 90% of the files when iphoto crashed, but I was monitoring it in finder only to see my free space go from 29gb to 10gb. Why do I need more than twice the memory card capacity to import these photos?
