Fan spinning up causes programs to hang...

I've been using a new Satellite A505-S6005 (Win7, i3-330m, 4G RAM) for almost three months now and I like it a lot. I bought it for general browsing and typing, messing around with some light-ish imaging and music apps, and playing older games. It does a great job, except when running certain programs (and most games).
When I fire up something like FL Studio (a digital audio workstation, which is fairly processor-intensive... and probably more-so because of the standard sound card), it runs great until the fan kicks on. When that happens, the program hangs up and the sound repeats like a broken record. After 4 or 5 seconds everything goes back to normal, and the fan slows down again. This happens again and again roughly every 30 seconds, maybe every minute.
I thought FL Studio might just be putting too much strain on the CPU (though its in-program CPU meter shows that it never goes above 40% and I don't run any major processes in the background) until I installed an old copy of Warcraft III. The game does the exact same thing...runs incredibly well and then just locks up for a few seconds when the fan kicks on, then runs incredibly well again...and it came out roughly 8 years ago. Sometimes it will hang up every 10 seconds depending on how many people are on the screen, which makes it pretty much zero fun.
Almost all of the games I've installed so far do this to varying degrees.
So what's up? The computer is well above the system requirements of these programs. Why does the fan trigger the lockups? Does the fan need a ton of processor power because it's really really really smart?
Thanks in advance,
-Ian
P.S. - It does this plugged in and on battery. I switched the power management options around between active and passive and nothing changed...could something be wrong with my fan? It's kicking on every 30 seconds or so right now, and I'm just typing this with one browser window open and no other programs running.

Terrifically old post, but still. I'm on a different model of Satellite, but I'm having a similar issue: every so often, the fan will spin up suddenly, the computer will hang for about a second, then the fan will slow down again and everything resumes as usual. Any ideas? Anyone?

Process.waitFor() causes program to hang!

I've successfully created a Process and run it using Runtime's exec(String path), and the kinds of processes I've successfully run have included Winzip, a WS_FTP Pro script, and a regular .bat file. I've also successfully called waitFor() on these processes, but in this particular case I'm calling a program that takes a file I give it as a parameter and merges its data into a database. I've been doing this procedure for a while (either from a command line or in a .bat file), but now I need to call it from my Java code. Preferably I'd like to waitFor() the process each time because I need to make sure all the files are merged in chronological order. My current test case only uses ONE file, but in reality there will be several. With one file, I can run the program and it appears to run fine (and it runs fast--like maybe a second or two at most), but whenever I call the following line it hangs indefinitely (I've never seen it terminate, even after several minutes):
focusProcess.waitFor();
When I just execute that program by itself by calling a .bat file with a hardcoded filename, I get standard output back from the program I'm calling. I'd like to see this output when I run my Java program and it appears to run fine, because I have no way if it IS running correctly! So, I added the following:
BufferedInputStream bis = new BufferedInputStream(focusProcess.getInputStream());
StringBuffer sb = new StringBuffer();
int c;
while((c=bis.read()) != -1) {
sb.append(c);
bis.close();
I'm not sure if this is the right way to monitor that InputStream that I get from the process, and even if that InputStream is going to give me the standard output from that the process normally writes to the terminal. All I do know is that again, the program seems to hang indefinitely, and I guess it has to do with the fact that maybe this process isn't notifying me that it's terminated, and so I'm still waiting for the rest of that InputStream. And yes, I HAVE tried both of these situations together AND separately (so I know that both pieces of code cause the program to hang).
Any ideas would be much appreciated!

Paying attention to the standard output from the running process is good for debugging (and reporting program progression, if necessary) but probably doesn't contribute to the problem you are seeing. The standard input to the process, however, is a different story. If the process you have Runtime.exec'd is waiting for something on stdin, then the OS will block on behalf of the program that is blocking for input and never terminate!
Try running the exec'd command from the command-line and see if it needs any input (i.e. you have to press a key, or enter, or send EOF) for the program to complete. If this is the case then your Java program must supply that process with the appropriate input or it will just hang.
As for printing the output from a process... here's a quick proof of concept:
import java.io.*;
public class Exec {
    public static void main(String args[]) throws Exception {
        // Make sure we've got something to exec.
        if ( args == null || args.length < 1 ) {
            System.out.println("Usage: java Exec COMMAND [ARGS...]");
            System.exit(1);
        // Run the process and print the output.
        Process p = Runtime.getRuntime().exec(args);
        BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String line;
        while ( (line=in.readLine()) != null ) {
            System.out.println("EXEC: "+line);
}Hope this helps!

My efforts to remove malware from a network external hard drive connected to my Intel based iMac is now causing programs to hang when I try to open them.

I own an iMac, recently updated with OSX 10.75. It is the core computer on a home network shared with an iPad, Apple TV, two network printers,my wife's laptop, two iPhone, a BlackBerry and a BlackBerry Playbook. I am experiencing three if not four problems that are overwhelming.
My original problem is associated with Windows emails files or documents stored on my external network hard drive. One or more has malware and is sending malware laced files across the Internet to points unknown. As someone pointed out in a forum my iMac may be hosting,sharing and propagating Windows malware. I originally used Trend Micro software on my IMac to monitor any viral activity. Two weeks ago I noticed a number of notices from servers around the world saying my message was not undelivered. Since I had sent messages to the people I simply deleted the emails. Next I noticed the emails on my BlackBerry and my BlackBerry playbook.I configured the Trend to do a complete scan and although it did a complete scan it did not perform a full network scan. It did identify a series of .x27 document files with the same name tbut each had a sequential number. I assumed hat these were the source files that had sent out the email documents selling Viagara and othernproducts. I manually deleted thousands of the source documents and the files. This caused some disruption to my computer but it did not produce a hardware or software problem. By following this effort in conjunction with security scans I do believe the malware was activated by Iranian students who were able to activate the malware through my BlackBerry and BlackBerry Playbook. I learned this from an encounter I had when trying tondelete these files on my computer and my BlackBerry.
When using my PlayBook after deleting the files from my computer I noticed more messages being returned from servers. I realized that email accounts connected to my BlackBerry and BB Playbookn were not protected from this problem. As I searched for remedies I learned about turning on the firewall in the previous version of Lion but that did not stop the BlackBerry problem. Each time I deleted a source file on my computer more documents were released. I eventually received McAfee from my ISP. It provided security on the entire network. My first full scan of my external drive identified two malware files. One of them was associated with the Cialis ad the other was from a firm in the Middle East called ADP. it could not remove the latter file.
Moreover each time I attempted to remove the source file from my hard drive a file labeled A239A076F would show up on my Blackberry. As I removed them thousands of these files would show up. Ultimately I eventually disconnected the external hard drive and removed the battery from the phone and not use the email accounts these messages had used to enter my iMac. I am contacting ATT about BlackBerry data security and switching to a different phone for business purposes. I will probably change to an iPhone or Android phone for business purposes. I am also looking at ways to resolve the malware on that drive. There are a number of business and personal files on thatbdrive that I hope to keep. I dread having to pay McAfee to configure the software to eradicate the malware.
Moving on...last week I updated my iMac to 10.75. It simultaneously updated every Apple based program as promised. It did not update the non-Apple programs. I am not an IT professional and assumed that it had done so. On Saturday I attempted to download a file associated with my router extender using my untethered Playbook and BlackBerry desktop software. The program hung. I attempted a reboot and it reopened with the hung program. It created an alias file on the desktop. My inclination led to put the alias file in the trash can and delete it. My computer did not respond well to that action. It has been rebooted with Cmd-s-esc tens of time to see if that would activate a file check. It did not. I was able to run a disk utility check. And in spite of the hung process it eventually said the drive was okay.
Long story in a nutshell. My iMac is responding as if it is looking for a subprogram to complete its a function. Or it is attempting to finish the BlackBerry operation it began on Saturday. I hope this makes sense to someone and the know how I can restore functionality to my iMac.
Thank you.

I think the McAfee suite will do the trick when I pay them a one-time fee of $69 or $179 for a year for unlimited support.
Your call of course but IMO a waste of money. Please read this first:
There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac has NOT been infected by a virus, it may have another security-related problem, but more likely a technical problem unrelated to any malware threat.

Program links cause programs to hang

Whenever I click a link that opens a program to launch a file, the programs jumps in the dock repeatedly and hangs. But if I open the program first and then manually select the file to open, this does not happen. One recurring example is if I click a torrent link that launches Transmission, it will hang. But when I force quit and then manually re-launch Transmission it comes up fine and the torrent will already be added.

I also wanted to a few more examples of programs hanging. When I option-click a dmg and select open with disk utility, the program hangs. When I double-click an installer file for an application, the installer hangs. Also I cannot mount dmg files unless I logout and back in.

Transferring photos from camera or memory card causes iPhoto to hang up with the spinning beach ball - why

Transferring photos from camera or memory card causes iPhoto to hang up with the spinning beach ball - why? This happens only on a 5 year old iMac running 10.6.8. It is a recent developmemt. All other machines have no problen with the same card.

I click on the send feedback everytime it pops up with the force quit, so they'er getting it.
That sends a crash report. Its doubtful that these are ever seen by a human being, but more likely datamined. Sending feedback reaches an actual person.
My guess from yourdescription is that the portion of the OS (note, OS, not iPhoto) that manages the importing process is what's crashing.

Firefox regularly hangs after an unspecified period of use, and causes other programs to hang, and a forced system shutdown is necessary.

The firefox browser hangs after an unspecified period of time. Anything from a few minutes after system startup, up to 5-6 hours of use or perhaps more. Attempting to use other programs including windows explorer while firefox is hanging causes those programs to hang also, making a forced shutdown necessary. Occaisionally I've noticed firefox will respond, perhaps after 10 or more minutes. There seems to be no hard disk activity while the program hangs. Memory usage of firefox on my system is usually upwards of 190,000.

I have circumvented this mostly by running internet explorer, and using Firefox only for browsing when I need to make use of it's addons. In this way I've had the problem re-occur maybe once or twice in the past two weeks. It's not really a solution but it does seem to help, and I'm no longer sure the problem IS firefox but using it certainly exacerbates the problem.
I've only just updated to firefox 6, so I am not entirely sure how that will go just yet.

Safari causing full-system hang

For a while now I've been getting the SBOD irregularly in Safari, since 3.x if I remember right. I've got some time off work at the minute so I'm finally looking into this properly, and here's what I've found:
There seems to be two separate conditions. The first happens on loading some, but not all web pages, causes a lengthy hang in which the entire system (even invoking Dashboard or Spaces) becomes unresponsive. In the console this accompanied by an entry similar to the following:
05/10/2010 08:15:47 /Applications/Safari.app/Contents/MacOS/Safari[242] ATS AutoActivation: Query timed out. (elapsed 5.0 seconds. params: queryString = {comapple_ats_namepostscript == "Helvetica-Neue" && kMDItemContentTypeTree != com.adobe.postscript-lwfn-font}, valueListAttrs = {<CFArray 0x6f5710 [0xa008dee0]>{type = immutable, count = 1, values = (
0 : <CFString 0xa01602c8 [0xa008dee0]>{contents = "kMDItemContentType"}
)}}, sortingAttrs = {<CFArray 0x6f5730 [0xa008dee0]>{type = immutable, count = 1, values = (
0 : <CFString 0xa01603a8 [0xa008dee0]>{contents = "kMDItemContentModificationDate"}
)}}, scopeList = {<CFArray 0x6f5750 [0xa008dee0]>{type = immutable, count = 1, values = (
0 : <CFString 0xa0161a98 [0xa008dee0]>{contents = "kMDQueryScopeComputer"}
(sometimes it names a font, sometimes the font name is "_")
I suspect this means some vestigial adobe product has messed my system right up. I used to use CS4 but have long since removed it. I also have Air and Flash (the current gala beta) installed. I have had fontbook validate Helvetica Neue and check all fonts for duplicates - if external disks are plugged in at this time they all spin up.
The other case is when downloading a file through clicking a link or alt-clicking a link (right-clicking a picture and saving it to the downloads folder does not cause this behaviour), and is accompanied by this much sparser line in the console:
05/10/2010 08:25:06 kernel disk0s2: I/O error.
The files themselves can be opened, moved and copied without incident and at regular speeds, so I doubt disk corruption. I've also performed a few full clone/restores on my boot disk with no effect. My initial thoughts were to blame a long-forgotten folder action that sorted downloads into different places (including a network share, if present), but disabling folder actions has not helped.
So, any ideas? I'm fresh out.

A workaround for the font-problem seems to be to turn off ATS - it's in FontBook.
The second issue still eludes me.
Things I have tried:
Trashing ~/Library/Safari/
Trashing ~/Library/Preferences/com.apple.Safari*
Cleaning out every vestigial trace of anything suspect I had on my system (google keystone, logitech control centre, SIMBL, The Spark, iStat Menus, folder actions)
Interestingly, the issue is not present for the guest user, so it IS something wrong with my user account. I just can't figure out what.
Yes, making a brand new account would fix all this, providing I'm meticulous about testing the issue as I move /Users/Old/ into /Users/New/, but I'm kind of loathe to give up. It's surely something really simple!

Non-Apple browsers cause cascading system hang with clean install of Lion

It started with Google Chrome. After a few hours of use, Chrome would randomly lock up one renderer at a time until it was completely unresponsive. Console showed nothing conclusive in the logs, and would soon lock up itself. Logged-in Terminal windows could sometimes get as far as a "ps auxc", but would lock up during the command output, and new Terminal windows or tabs would never get past login. The SSH daemon would be dead in the water, preventing me from logging in remotely. Any existing SSH connections would hang on the first command. Activity Monitor would lock up the moment I tried to sample a process or interact with anything. Interacting with SystemUIServer (pulling down the menu for the clock or trying to do a Spotlight search) would cause SystemUIServer to hang. Same with the Dock. My mouse was like the Midas of software failure: everything I touched turned to hang. Eventually I'd be staring at a spinning beachball. After a few (five to ten) minutes, it might perform a couple queued events (opening a window, switching to another application) but would usually become wedged again immediately, forcing me to hard restart.
I then tried installing Firefox 5, and discovered that it causes the hang fairly reliably within the first ten seconds. Since I knew when it was about to happen, I managed to capture a few stack traces in Activity Monitor, but it was always different, and always somewhere in the kernel (usually file-system related: __getattrlist while scanning fonts one time, the open system call another).
Safari, on the other hand, works great.
I've tried performing a verification of my startup disk, which returns no errors, so although I'm not ruling out hardware failure at this point the problem started immediately after I upgraded to Lion, and persisted even after I wiped my hard drive completely and performed a clean install from the recovery partition. It also doesn't seem to be completely the fault of either Chrome or Firefox, since they're different browsers with different rendering engines using different system frameworks. They do both perform a lot of file I/O, so maybe that's a clue. Another possible lead is the seemingly random errors Console will spew out while the hang is occuring. Most recently I've gotten a screenful of '--ImageKit Error: updateGLTextureWithBitmapData: glPixelStorei returned an error : 506 ...', and before that it was 'Google Chrome Helper: CGSLookupServerRootPort: Failed to look up the port for "com.apple.windowserver.active" (1100)', "kernel: IOSurface: buffer allocation size is zero". Console spew being what it is, though, I don't know if any of that is relevant.
I figure I would be seeing quite a lot of angry forum threads if Chrome and Firefox were completely unusable on other people's machines, so I'm guessing there's something specific to my configuration happening here. With a clean install, though, I'm not sure what it could be. Here are detailed system specs:
24" iMac (Early 2008 -- just out of AppleCare coverage, figures) , 2.8 GHz, 2GB RAM, running Lion build 11A511 (which should be the 10.7 release version).
I would be massively indebted to anyone who has experienced or heard about this issue before and can give me something else to try.

Zeroing the disk serves no purpose in this situation. It is a common misconception that this is required to map out bad blocks on the drive, but the fact is that 1) modern hard drives map out bad blocks as part of everyday operation, and 2) zeroing the drive involves simply writing zeros with no checks to see if the zero was written successfully, so it wouldn't know if a block was bad anyway.
It's possible the drive is starting to go bad, although then there should be some problems with SL as well. I would recommend repartitioning the drive with Disk Utility. Make sure it's got one partition, using the GUID partition map scheme, and format that partition as Mac OS Extended (Journaled). Repartitioning should get rid of any gremlins lurking on the disk, unless the physical disk itself is dying. And after repartitioning, install straight from the flash drive, as Shootist recommends, rather than installing SL first.
Hardware could be an issue. It's entirely possible for an older system to work fine on slightly faulty hardware while a newer system does not. Running Apple Hardware Test wouldn't be a bad idea.
Firmware updates wouldn't be a bad idea. However, note that my mid-2010 MBP with the same specs is running Lion just fine, and I've never installed any firmware updates. (Firmware updates scare me... if my machine is running just fine, I'm reluctant to risk installing new firmware. But that's probably just a bit of paranoia talking. )

Labview Program will hang between 33% and 50% of the time.

I have a problem with a Labview program I made. I have two programs that do the same thing. One is in flat sequence form and the other is in state machine form.
As explained in the link below, I would like to make use of a microcontroller to make wiring connections for automating a measurement process. A separate current source and volt meter will be used.
https://forums.ni.com/t5/LabVIEW/Sequence-a-good-idea/td-p/2601333
I have since made some simple test programs which I have attached. The problem is when executing, the labview program will hang, but not every time the program is execute.
For example: Hall 1.2.vi will work properly twice with the third time it is executed it will hang. If you abort and try again, it will again run twice with no problems with the third hanging. This one is in flat sequence format (was in a flat sequence, but merged the windows because I thought that was the cause). From what I can tell, the program will hang when calling Keithley 6517 Single Read.vi. Both connected Keithley devices are connected to the computer via GPIB at 16 and 27. The way I verified if it was this vi causing it or contributing to it was that I removed it and the program never hung. I find it very strange that it will hang exactly on the third attempt every time.
Hall 1.3 simple.vi will work the first time and hang the second time. So it works 50% of the time. This one is in State Machine format. This one will hang at the case titled "Measure 1" which contains the Keithley 6517 Single Read.vi.
I've used the highlight execution button and watched the program run. Oddly, it doesn't hang when using this button. So I tried adding delays/wait in different places to no avail.
What could be causing this? As a side note, I say the program hangs for two reason. The main one is the program doesn't finish running so the run arrow is still black. The second thing is that if you notice at the end of the labview program, I have a block there that turns the current source off which doesn't happen when it hangs. I have to manually turn it off and then hit the abort program button to stop labview.
Solved!

Also, I've tried placing wait/delays at various places with no improvement of the problem. My next thought is to just remove all the vi calls and have everything in one program.
How did you place the waits?
Why would placing everything in one program fix the problem. That makes no sense! What is your reasoning?
In the case of hall1.3, I placed a wait in the Measurement cases and CS On cases and there was no affect. In the hall 1.2 when the blocks were broken up similar to the state machine cases where each sequence window was identical to the cases, I placed a wait or delay in each window with no effect on the hanging.
My reasoning for placing everything in one program is the same as my reasoning for figuring delays would help, since the time of execution would be altered. If the execution time is faster and if the timing is the problem then I figured that the problem would happen more frequently or even every time.
Somehow I get the feeling this is not the case. The reason being the interval in which it succeeds or hangs is constant. I believe somewhere, a value is getting set. The 6517 Read vi runs fine if I run this vi by itself no matter how many or how fast I run it. Also, the same goes for both 1.2 and 1.3 if I remove the 6517 read vi they run fine no matter how fast or how many times I run them.
Somehow after the current source is set to operate and triggers labview will hang on a set interval when calling 6517 read vi.
Separately they work, together there is a problem. I tried placing a delay between these two by connecting the error out of the trigger vi to the error in of the delay block and the error out of the delay block to the error in terminal of the 6517 config block. I've also tried delays between other blocks connected the same way. From what I understand, a called vi can't execute until all inputs are present. Is this the correct way to wire the delays?

Switch to RAW decode 2.0 causes Aperture to hang

My apologies if this has already been posted. I didn't see this question anywhere else in the forums.
I converted to Aperture 2.0 and have a library of about 25k images. I have shot with a Nikon D100, D200 and D300 and have images from each in my library. I am pleased with the appearance of many of my images with RAW decode 1.0 and 1.1 so don't want to migrate my entire library to 2.0. I am able to convert some of my images to 2.0 with no problem. Several images, though, refuse to convert. When switching the decode from 1.0 to 1.1 or 2.0 or from 1.1 to 2.0, I get the spinning beach ball of death and have to force quit Aperture. Sometimes the image will convert when I restart Aperture and sometimes it won't. One image in particular was shot with my D100 and consistently causes Aperture to hang when changing the decode from 1.0 to 2.0.
Any ideas on how to fix this problem and get that image to decode 2.0?
Any help is much appreciated.

Why does fan spin for 1 second only? K7N2GM-1L

Hi Guys,
First post here. I have read all the stickies and FAQs, but I don't seem to have found an answer to my specific problem. If it is here, and I missed it, please just point me to it and accept my apologies ( and thanks) in advance.
I have just put in a K7N2GM-1L for a friend who was struggling. When I hit the case power switch, the CPU fan spins for about 1 second, then stops. Nothing else happens. If I reset the power switch on the PSU (i.e. set from 1 to 0 then back to 1), I can repeat this process - but nothing seems to help get the board to progress onto POST.
I have tried with and without RAM. I have tried removing the power switch cable to the board, and shorting (briefly) with a screwdriver, in case the case switch was bad (same result). I have tried with no IDE drives, all IDE drives, with and without the floppy connected. I have tried the board mounted in the case, and outside the case (on a non-conducting surface) - always the same result.
After a lot of head scratching (I normally consider myself pretty competent inside a PC case, and have installed / upgraded / fixed numerous PCs) I realised I had done something pretty dumb. I had been powering the board with the BIOS reset jumper set in the RESET position. I know, I should have checked first, but I didn't :(
The manual says that this will *damage the board*, but does not give any further details. Does anyone know whether this is the real showstopper, or is it just a generally bad idea and there is still something else that I have not checked?
I see from many other posts that the PSU is pretty critical to these boards. I have tried two separate PSUs - both from known working systems. Specs are below.
Jeantech 400W
+5V = 35A
+3.3V = 28A
+12V1 = 15A
+12V2 = 17A
-5V = 0.3A
-12V = 0.8A
+5V SB = 2A
Jeantech 500W
+5V = 40A
+3.3V = 30A
+12V = 18A
-5V = 0.3A
-12V = 0.8A
+5V SB = 2A

Yes, having the cmos clear jumper in the wrong position can damage the motherboard. I don't believe that it is an automatice thing to happen since I have done the same thing a time or two myself without any resulting problems
How many times did you try to start the system with the jumper set wrong? That may give us the answer since multiple tries might have been too much for the motherboard to endure.
Can you try the pieces in another system to verify if they are all good? If they check out, then it is probably time to request an rma on the motherboard.
It would help if you told us what other pieces are in the system: cpu-memory-video card-hard drives-optical drives-pci cards as I are just guessing now.
I'm afraid I probably started the board with the jumper in the wrong position a dozen times or so, while trying various combinations of other possible faults before I realised the jumper setting was wrong :(
The system is essentially bare at the moment - just a floppy, a stick of RAM, CPU (Athlon 1800), onboard graphics, no monitor, no PCI cards.
Just to humour me for a moment..... if we assumed that no damage was done by the CMOS jumper setting, what else might be causing the symptoms described in my post above? Any thoughts?

Fans spin up only in one account

I have a late 2010 MacBook Air (2.13/256GB SSD/4GB RAM running 10.6.8) and when I'm in my user account the fan spins up to 5200 RPM with the CPU temp at 79°. When I login to the guest account, the fan operates at its normal speed. In my user account, with the fan at 5200RPM, I'll have no applications open (including in the menu bar) and the fan is still spinning too fast.
I've downloaded SMC Fan Controller, and when I ask to manually override the fan it will ignore my request and spin it at its current rate of 5200RPM. I can ask SMC to spin it faster, and it will spin faster. I can not get it to spin slower.
I know it's probably unrelated, but the issue started happening immediately after I performed the latest Java update. I know it's not software related as the fan behaves normally in other user accounts. Also I only have 4GB free on my SSD, could that be causing it? It would be strange if it were, as I've had roughly that much space for a few months now and the issue just began a few days ago.
It's like I'm sitting in front of my Dell from 10 years ago. The fan is so obnoxious and loud, it's difficult to concentrate.
I'm currently traveling where there are no Apple Stores or Apple Authorized Centers, so I'm out of luck there.
Any help the community can provide would be much appreciated. Thank you!

I've performed an SMC and PRAM reset, still the same issue. But it's definitely hardware as it only shows up in one account.
I launched Activity Monitor and found a process (SparkleShare) to be eating 45% of my CPU usage. I terminated the process and the fans spun down a bit, there still a little too high though. Will wait to see if they cool down after a bit and report back.
Thanks!

After Yosemite, a new email message causes Mail to hang

After upgrading to Yosemite last evening, opening a "compose new message" window in Mail causes Mail to hang (crash?). I'm able to receive email messages, but I can only send messages by booting my MacBook Air in "Safe" mode. (Opening Mail in "safe" mode does not keep Mail from crashing when I open a "compose new message" window.)
I haven't been able to get far enough to see if trying to "send" a message will make Mail crash. Just opening a "compose new message" window and trying to put the cursor in the address line, subject line, or message area will cause Mail to spin away into infinity.
I do use three Mail add-ins: MailTags, Mail Act-On and the Daylite Mail Assistant; but all of those are the most current versions and their developers claim that they are compatible with Yosemite.

Welcome to Yosemite beta. I havent been able to use Mail since I "upgraded" 4 days ago. Apparently the solution is to wait until Apple figures out what went wrong.

IPhoto 11 fan spinning very loudly

Hi,
I have a 2004 i7 15" Macbook Pro, when I startup iPhoto 11 (version 9.4.3) the fan spins really fast and I can hear it clearly. Also, the MBP will heat up and then reboot itself.
So I just bought a 2013 i7 13" Macbook Air, same problem, the fan spins loudly and then MBA heats up.
Can anyone help?
Thx and cheers,

That's what happens when an pp hangs or is in someother way distressed. Have you the same library on both machines?
As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?
Post back with the result.

MacBook Pro - Fans spin up on power on

Hi,
I got my MBP back the night before last night, it was in for a major repair in which they replaced the Main-board (includes new SDD, RAM, Fans, I/O board, I/O Flex cable as well as the Clamshell Retina display (Complete))
The issue I was having before, after my MBP "burn-out" something inside, which caused them to replace everything, still seams to be happening.
My fans spin-up as soon as you turn the power on.
They also stay on the whole day (and never go off).
I know this is not the standard case with the MBP - as I have confirmed this with the genius at the apple store when I took it in last night - and he told me that it was "not doing it any more" ... and I got home, turned it on... and it was doing it still .... what a waste of a trip to the Apple Store on that one
I wanted to know if other had this issue, and if its perhaps an installed app. I have the widget iStats (which is loaded on the widget screen all the time) ... To check things, and after googling things, I installed smcFan control... in which I am NOT able to tell it "not" to spin the fans, there is no option in the APP that has a minimum speed of 0 (zero) I also installed the "Macs Fan Control.app" - which also does not have the option to make a zero minimum spin speed.
Because the MBP's fans come on immediately when I turn the power ON... and stay on through log-in, and boot up... and the whole day... I struggle to see it as a software issue - unless one app along the way set something in the machine config that tells it to always be on...
During use of the MBP, and when it does get "hot" ... the fans also do not seam to spin up faster to cool it down, knowing that this algorithm may think its not necesary to cool it down when the GPU Diode is cooking at 155 degrees F - the SSD is running over 115 degrees F - the CPU Heatsink is at 126 degrees... and so on... I in this case used smcFan to cool it down by manually increasing the fan-speed (I otherwise do not have either of the fan-speed apps running automatically on boot, the only one is the iStat widget, which as far as I see does not "control" it only "reads" the values)
Is there anything I can check for this.... I really don't want to waste my time again going to the Apple Store to have a genius tell me they are not on, to get back home again to see that they are still on :S
Thanks!
Brad

EDIT: I notice that when using smcFanControl, you can set the "Default" for the fan speed... In this app you can not select a minimum speed of less than 2100 left, and 2000 right... Going into the other app, Macs Fan Control (MFC) it tells you the minimum speed that "can" be used is the same as what I make the minimum with the smcFan app... i.e... If I make the minimum for both fans 4000 in smc, then close it... and open MFC... then MFC tells me that the minimum fan speed is 4000.... This makes me think that smcFanControl is updating a system setting to tell is what the minimum fan speed is... which would make sense that when booting from power off, the fan speed is already set to the minimum. ( I will confirm this by setting it HIGH, and powering off, then powering off again - and will update this thread ONLY if I am wrong in the understanding that on powering ON again, that my fan speed will come on as I power on at the HIGH speed that I set it in smcFanControl!!! Only if I am wrong) ... which would lead me to the question to the Apple geniuses, of "How do I then set my "default" minimum fan-speed back to zero?? ( and I can then un-install the fan-applications, as I only installed them to see if I could control the fan speed to make it zero, which I can't)
I have only a few apps open right now while I type this, and checking activity log, FireFox which seams to be using a LOT of cpu power for me to type into this box (I must be typing blazing fast - not ) ... which makes my GPU Diode to go over 155 degrees F :S)
:END EDIT
