Fan won't shut down after install of 10.6

My fan on my Macbook Pro will not turn off while the notebook is on it is at max speed. The only time prior to this that I had my fan run this loud is when I have played a game like call of duty 4 since installing 10.6 my fan won't stop running like that even if no applications are running just from boot

Have you tried Resetting the System Management Controller (SMC)? According to the this document you may need to reset the SMC if your fans run on high speed when the system is not warm.

  • My Macbook Pro won't shut down after installing Lion.  Anyone have a suggestion to fix this?

    Just installed Lion, and it won't shutdown!
    The only way it'll shut down is if it drains the battery.
    Help!

    Lots of other people are complaining about their Macs taking long times to shutdown. Some solved it by reinstalling Lion from scratch (without using a Time Machine backup and simply copying all their files on to the new install).
    Others discovered old software that is no longer compatible with Lion (I found Mac The Ripper in mine, plus many others on day 1). I uninstalled some apps using App Cleaner (google it, it's free and it's awesome).
    I was having a hard time shutting down my macbook pro, now it's back to normal.
    Try finding applications that are not compatible with Lion. Their icons should be greyed out and with a diagonal line crossing it. Make sure you erase these applications and library related files, which is very simple if you use App Cleaner. And make sure you look into sub-folders inside the Applications folder, as I missed a couple because they were not immediately visible.
    Hope it helps. If it does, let us know.

  • Macbook Pro won't shut down after installing Yosemite

    Hi,
    I just finished installing Yosemite on my Macbook Pro. It's fairly new, the last version with a DVD drive but without retina display (I bought it in May 2014 and it's my first Mac).
    I installed Yosemite, updated all my applications from the App Store and tried to shut it down from the Finder but the screen just freezes on a black screen wth the pointer showing and then I to shut it down using the power button which I hate doing.
    I turned on FireVault after set up and that is busy encrypting could that be causing this? I did check online and it says you can put your Mac to sleep or shut it down while this is happening, but I haven't been able to. Any tips would be great.

    I had the same problem and just fixed it.
    What I did:
    - Launch Disk Utility > Select Macintosh HD > Verify Disk
    Let the Verify run until it's done
    - If you are seeing any error try the Repair disk
    It's possible you need to restart (holding cmd+r while restarting)
    - Next I did a verify disk permissions and a repair disk permissions
    - reboot
    After this the shutdown issue was gone!
    Hope this solves your problem as well.

  • My Mac 10.7.5 won't shut down after new software (security update 2013-003) installation-- hangs at grey screen with "software update" at top.  It also intermittently goes to sleep without my asking.  What to do?

    My Mac 10.7.5 won't shut down after a new software installation (Security Update 2013-003).  It just hangs at a grey screen with "Software Update" at the top.  I have to force quit, then restart-- but the new software hasn't installed.
    My Mac also intermittently goes into Sleep mode, repeatedly, unprompted by me.  I suspect a connection between these two problems.
    I have tried deleting the /Library/Updates folder.  It hasn't helped.  The update still won't install, and my Mac won't shut down without my forcing the quit.
    Help please!

    Hi, I've just come accross the same problem... did you manage to get a resolution??

  • After having shut down after installing updates, when I restarted and tried to open a word file, it started opening ALL the word docs and the only way I could stop it was by"force quit"  arted  and tried to open

    After having shut down after installing updates, when I restarted and tried to open a word doc, it started opening ALL the word docs and the only way I could stop it was by"force quit"  . This is REALLY annoying!!

    May be it is the Resume feature.
    System Preference > General > Number of recent items
    Uncheck the box next to      "Restore windows when quitting and re-opening apps".
    Best.

  • Won't shut down after Tiger 10.4 install

  • My Mac won't shut down after upgrading to Panther

    I recently upgraded to Panther 10.3 from Jaguar 10.2.9. After Panther had installed successfully, I used software update and I'm now running Panther 10.3.9. However, since then my Mac won't shut down. It doesn't hang or freeze - it just does nothing at all.
    I've made sure no applications are running or have frozen. I've tried booting up from the OS X disk and running Disk Repair, and I've also tried using the 'fsck' tool. (I entered '/sbin/fsck -f' in single-user mode). Nothing has worked.
    Now each time I want to shut down, I have to force shut down. Can anyone help?

    Hard shutdowns can cause disk damage. You are better off leaving your Mac on until the problem is sorted.
    Have you disconnected all peripheral devices (unmount firewire drives before disconnecting) except Apple keyboard and mouse and tried shutdown? Often peripherals can kick back a signal to the cpu preventing shutdown.

  • MacBook Pro sometime won't shut down after Lion installation.

    After installation of Lion my new MacBook Pro (early 2011) sometime won't shut down in the normal way and I have to shut it down using the power botton.

    Make sure you quit out of all programs prior to shuting down if you have not done so.
    Boot up from your install DVD and run "Repair Disk" from the Utility menu.

  • External hard drive won't shut down after switch from OS10.5 to OS10.4.11

    i recently chanded my OS from 10.5 to 10.4.11 (as a programme i want to use is not compatible with leopard), but since i have done this my external hard-drive won't shut down automatically when i shut down my mac. i have to switch it off at the plug instead.
    can anyone suggest how i can get it to do this again?
    i'm a little concerned that i'm damaging the external drive by turning it off manually all the time..
    thanks

    Some hard drives shut off with shutdown, some don't. Sometimes hard drives that did shut off with one system will not do the same with a different system. My hard drives which did shut off, prior to 10.5 now stay on.
    This is not really a problem as all hard drives spin down after 10- 20 minutes when not in use, whether your computer is on or off. Leaving the drive on is fine, shutting it off manually is fine.

  • 10.5.8 won't shut down after bad SD disk removal.  It stops all applications but won't get past the final shut down screen.

    I had a disk error with a SD disk from my camera.  Removed the disk from the card reader and got the Disk Removal Error alert.  Then the whole thing froze up on me.  Noting else would eject, No other apps would shut down and basically nothing worked.  I couldn't shut down so I removed the battery.  Restarted the computer ok then tried to repair the SD disk in question.  No luck on the repair so ejected it again.  Then tried to restart OS and it won't shut down again except everything still works but it just won't shut down.

  • Cleaned Fan, Now Laptop Shuts Down After 1 hr.

    I own a pavilion dv5 1140tx laptop and for the past few months it has been really overheating and so I decided to open it up and clean the fan. This laptop is really poorly designed since you have to completely dismantle it to get to the fan. Like I had to take out the HDD, Monitor, Mothe Board, Optical Drive, everything!!!
    Anyway I cleaned out the fan which had a considerable amount of dust in it (its 3 years old) and then I peiced it back together. After that it seemed that the fan was running a bit more smoothly and there was far less heat coming from the laptop, I turened it on and everything works the same but after about an hour of use it shuts itself down just as it would if it were overheating, but it isn't anywhere near as hot as it used to get.
    I set it to a balanced power setting, and changed the BIOS so that the fan isn't constantly running and that seems to have helped it but it still shuts down after a while!
    Might it be that the heat sink isn't close enough to the CPU and so the CPU over heats before the heat can disapate into the heatsink? Anyone else have this problem?

    Hi Mario,
    Before cleaning the fan with an air duster can, I restored the computer to factory settings. It was only after that my laptop started shutting down shortly after start-up. It stopped doing that eventually, but what I did to prevent overheating is I sprayed the fan's underneath the laptop with air from an air duster can to remove any possible dust clogging, thereby causing the fun to work much harder than it normally should, and it seems to be running fine now. I haven't had any problems with start-up, and in fact, when in use, it doesn't make as much noise at is use to. My laptop used to ramp up the fan speed quite often because not enough heat was being expelled from the laptop. Luckily, it doesn't do that anymore.
    Doing further research led me to a video  called: "Reducing Heat and Fan Noise in Desktop and Notebook PC's" on HP's support page.
    If anyone ever does research on the same issue and this post ends up as a result to what you are researching for, than I suggest what Mario said, but also watch the video I referenced above by following this link:

  • IMac won't shut down after using Time Machine

    Here is the thing: My iMac (late 2009, 24", 8 GB RAM) won't shut down when I use my external HD for Time Machine. After the back up I try to eject the external HD but the icon won't disappear on the screen, it only gets blank and is not clickable anymore. It is still visible in the menu of the Finder but with no ejection sign anymore. Programs that were open before won't close even if I use the forced shut down function. But it seems like they are closed as they don't appear on the list anymore. When I then try to shut down the whole system the screen goes black and the wheel turns for hours! So that I finally have to shut it down manually.
    This happens only after using the external HD for the back ups and when I then try to eject it. If I don't eject it everything goes normal. If I don't connect it everything goes normal. Sure, you might say, hey leave it plugged in then. But as it is a 3 TB HD I also use it for my MBP so I have to eject it
    Is this a known issue or a bug in the system of Yosemite? With Mavericks everything worked really well - no problems at all. On the MBP (late 2011, i7, 8 GB RAM) it also works well. So I am kind of annoyed the I always have to shut the iMac down manually which can't be that healthy for the system.
    Any insights on that issue are highly appreciated - thanks a lot!
    Birgit

    Okay, just realized that the same problem occurs with the MBP after rejecting the external HD
    Icon gets blank, cannot be clicked anymore, while shutting down the MBP normally the screen goes black and the wheel is turning forever but nothing else happens. So I have to force it to shut down.
    It seems to be a general problem with connecting an external HD once in a while for doing a time machine back up regularly and then eject it. So the question is: who has the same problem or does everybody have their HD permanently connected to their Macs for Back ups? Either by USB or WLAN? It never was a problem wit Mavericks and I don't want to permanently back up my system every hour - once a week is good for me BUT this cannot be adjusted in the time machine settings which would be a very good idea.
    Any solution is still highly appreciated !!
    Thanks a lot,
    Birgit

  • Mac won't shut down after 10.6.8 update - a possible fix

    I noticed that after updating my MacBook Pro to 10.6.8 (using the latest 1.1 combo update) that often times when attempting to shut-down after using Safari the computer would just hang or, I'd get a message that said something like, "OSX didn't log you out because Safari did not quit...".
    After putting the system into SAFE BOOT mode and trying to launch Safari I was getting tons of errors about Flash Player plug-in 10.6 crashing.
    After downloading the latest Flash player plug-in from Adobe the hang-on-shutdown behavior seems to have stopped.
    FYI for those who haven't found a fix.

  • I5 iMac won't complete shut down after installing Lion

    When I try to shut down my iMac it gest as far as the white screen with the spinning wheel.  It never completes the shut down.  I always have to force quit it by holding down the power key.  Any suggestions?

    I have the same issue was fine after 10.7 install but happend straight after 10.7.1.  I have reset PRAM NVRAM and reset SMC, I have also been to the genious bar where they did an erase and install of lion, it then closed down six times and has now stopped closing down again.  I can't think of any other option i'm sure that it must be something in 10.7.1 so will wait for 10.7.2 with my fingers crossed.  Any other thoughts out there?

  • Adobe CS6 Apps Shuts Down After Installing Creative Cloud.

    I can't start my Photoshop, Illustrator or InDesign CS6 anymore, it just shuts down as soon as it's done loading, without any errors. Only Bridge CS6 will start.
    I tried launching with Ctrl+Alt and Ctrl+Alt+Shift but it did not work.
    Then I tried uninstalling it (With all the preferences as well), and install it again, that did nothing - still the same issue.
    I updated windows and my gfx drivers (GeForece 332.21 - NVS4200M) after the issue started.
    I tried both the 32bit and the 64bit version.
    I have manually removed the preferences file.
    I have disabled the firewall and my AV.
    I have logged out and back in of the Creative Suite Utility.
    My hosts file is not blocking any sites.
    I am running Windows 7 Enterprise 64 bit.
    I tried to open a issue on superuser but that did not help, nobody has awnsered it yet.

    Nicoar do you receive any specific error messages?  I would recommend starting with the steps listed in Error "Failed to Install" Creative Cloud Desktop application - http://helpx.adobe.com/creative-cloud/kb/failed-install-creative-cloud-desktop.html.
