IMac still overheating with Mountain Lion

Am still suffering WAY higher temps on my i7 iMac after installing Mountain Lion
CPU Core is 150 F while I do nothing but surf the web
Ultimately the mouse will move but be unable to perform any action
Need to unplug it from wall to shut it off

You're not alone. I have both a 2010-2011 iMac. Both i7 with 16 gigs of ram. Audio stutters, overheating, crashing, and now a memory leak. I've spoken with apple and I haven't gotten anywhere yet.
I spoke with a buddy who has 18 of these iMacs at his work. Mountain lion crippled them all. So, good job apple. If your goal is to shrink your Mac business, you're succeeding marvelously. If not, fire the idiots in OSX development and hire competent staff. What an embarrassing time to own a Mac.

Constant reboots on my iMac (early 2009) with Mountain Lion. Why?

I know there are a number of threads here speaking of similar problems, I've tried the steps mentioned there...to no avail.
I have an early 2009 iMac with a 24" display, 3.06 Ghz Core2 Duo. Memory has been upgraded to 8 GB.
The problem is: Since upgrading to Mountain Lion I get constant reboots, sometimes I can't even have the machine running for more than 30 minutes without it starting again. This is making it impossible for me to work. I've posted the last panic report at the end of this message. What I've noticed so far in all the panic messages is that the last loaded or unloaded extensions are always the same ones, no matter if my machine is restarting after 30 seconds or 4 hours. Could that be something helpful?

So it's ALWAYS either a file system extension or the USBCDC one. Always. Is that useless info or can I do some further testing in a specific direction here?
I've done the Apple Hardware Test in a loop for more than 8 hours without any problems, I've done a memtest in terminal without any problems. I've bootet in safe mode and still got a reboot. I've disconnected all external stuff (only using a Cintiq, a DAC with speakers and keyboard/mouse anyway)
Can anybody give me any more tips? Oh, and I've reinstalled Mountain Lion (clean install from recovery partition) a few times already. No change in behavior.
This is the very last crash report:

Update: It just happened again, this time while doing a backup with Time Machine. Could it be my Keyboard?
I'm not using a Bluetooth keyboard, but one with a USB connection. Sometimes I'm connecting my backup drive to it, but reboots also happen without anything connected to the keyboard.
This time there's even backtrace info:

IMac locks up with Mountain Lion with 10.8.1

My iMac is locking up with the SPOD since upgrading to Mountain Lion. So far the only fix I have found is to power off, unplug, wait, and plug in and power up, like a PC. Any ideas out there for how to fix? So far there are no updates other than 10.8.1 and this didn't help. Before upgrading this was not an issue. I find this happens when using Aperture 3 which is what we do most of the time. Any suggestions appreciated.

How much RAM does your iMac have installed?
Have you tried starting in Safe Mode and see if the problem still occurs?
Restart holding the "shift" key.
(Expect it to take longer to start this way because it runs a directory check first.)

HT4882 This no longer seems to work since Lion was installed and still not with Mountain Lion.

It seems this feature has stopped working only since Lion (now Mountain Lion)was installed. I wil try an old copy of an earlier OS as an external boot to check but this appears to be anOS upgrade problem.

The Swedish site you've linked is discussing .xmodmap, which is a hidden (hidden because of that leading dot) configuration file in your login home directory that's used to customize settings for the keyboard mapping within X11.
I'd expect the XQuartz tool to read ~/.xmodmap in your login directory as part of its initialization sequence.
The xmodmap tool (no leading dot, and not a hidden file) is an application that's used to process the configuration file.
When you invoke xmodmap (the tool), you either need to specify the full path /usr/X11/bin/xmodmap for it to be found and invoked, or you need to have the /usr/X11/bin/ directory added to your PATH. Your PATH is the list of directories where OS X looks for the tools you're invoking.
If the xmodmap tool is not working, are there any diagnostics? Or is XQuartz not honoring the request? (If so, see if it will honor the setting made via the .xmodmap configuration file.)
And if you don't get an answer here, you might try the (pretty quiet) Apple x11-users mailing list.

Is Quicktime broadcaster still viable with Mountain Lion?

Is anyone using QT broadcaster? Is it still a viable option with the latest OS? Is there a better solution for live broadcast? I want to do a live web presentation that could have audience feedback and also record it for streaming availability. I haven't seen anything about QT Broadcaster recently and wondering if it has been dropped or is it still an option?
Thanks

I cloud on my Imac with Mountain Lion - signing out means losing contacts, etc.

Help. I have tried to sign out of I cloud on my Imac with Mountain Lion but it says if I do so it will either delete my contacts, documents, etc. from the computer. Something is not right here. How can I prevent this from happening? Thank you.

You have to remember that your email, calendars and contacts live on the iCloud server, not on your Mac, and your Mac reads them from there (like webmail)*. So if you sign out, you don't affect the actual data in any way because it's still on the server, but your Mac loses access to it. When you sign back in it's all still there.
However, as Julian says, there is no reason to sign out unless you are actually having a technical problem that may be solved by signing out and in again. The whole idea is to stay signed in at all times.
*Just to clarify, your Mac maintains a cached copy of the data to speed things up, and so that you can still see it when you are signed in but have no internet connection; but this cache is deleted when you sign out. For practical purposes you can ignore it. As with all caches (and your Mac has a lot) it's hidden (hence the name) and can't be regarded as an actual copy.

HT1338 I have tried to updated my iMac with Mountain Lion.

HELP!! I have tried to updated my iMac with Mountain Lion, OS X 10,8,3 (12D78) to 10,8,4, it keeps asking me to restart to install the updates, having tried this 20 times the app still has update available and I just go round again. how can I get this to finish and update correctly

Try downloading the update from the Apple Downloads site. http://support.apple.com/kb/DL1658
Or, you might try booting into Safe Mode and try to install through App Store. http://support.apple.com/kb/ht1455

HT1338 im on osx snow leopard but the lion is no longer available on app store. How can i still upgrade to lion? my computer by the way is not compatible with mountain lion. thanks

Hello royalaqua,
I do think you should ask yourself if upgrading to Lion is the right course to take.
Snow Leopard is an excellent OS and Lion has literally been frozen out after barely a year. Remember too that some of your apps may not work with Lion (those that have Rosetta, for example) so that could mean more new purchases. Plus you may need to uprate your RAM too.

I have an iMac with mountain lion 10.8.3 with boot camp 5.0.2 .i installed windows 7 -64 bit with boot camp but the boot camp didn't install drivers for windows please guide me for trouble shooting .

Boot Camp doesn't install the drivers. You have the drivers on a separate USB device if you followed directions. Once in Windows connect the USB drive with the driver software. It should startup automatically and install the drivers.
You don't even need to do that. As downloading the drivers from within Boot Camp Assistant can be unreliable, it is better to get the package directly from here:

Copy the .zip file to a USB flash drive or burn it to a DVD in OS X. Install Windows as normal, insert the flash drive/DVD in Windows, copy the .zip file to the hard drive, extract it, then run the setup executable.

I've got a new iMac with Mountain Lion OS. Created a slideshow complete with music in iPhoto. Every time I try to export to iPhoto slideshow folder, it freezes. Help!

I've got a new iMac with Mountain Lion OS. Have created a slideshow complete with music in iPhoto, but every time that I try to export it to an iPhoto slideshow folder, it gets halfway through and freezes. This has been going on for a couple of days. I've tried opening iPhoto holding down the option key, but it doesn't make a difference. Any advice, please?

Upgrade to v9.4.1 or
Trash the HP Plug in from /Library/Application Support/iPhoto
There are two libraries where this plugin might be
HD/ Library
and
HD/Users/Your Name / Library
(On 10.7 or later: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)

I have iMac 27. After Mountain Lion install, my trackpad freezes partially after deep sleep and need to restart to get it working again. anyone with same issue?

I have an iMac 27 and installed Mountain Lion last week. Since then, after a deep overnight sleep, certain of my trackpad functions are frozen after i wake the Mac. i need to restart the computer in order to get the trackpad fully functional. Anyone with same issue or ideas?

I'm having the exact same issue with Mountain Lion on my 2008 17" MacBook Pro. I've just tried the SMC reset, so we'll see how that does. The problem was intermittent, occuring not after every wake--from-sleep, but every few.
Interestingly, my 2007 17" MacBook Pro is also running Mountain Lion (the oldest MacBook Pro than can!), and hasn't had this problem at all.

Could someone help me with instructions for doing a clean install for iMac with mountain lion 10.8.4 ?

   Barney, William, nbar, Galt\'s Gulch:
   A nephew stayed with us to take a course at the local community college last semester. I allowed him use of my mac for research just after I installed Mountain Lion. He decided to "help out" and ran a 3rd party clean and tune up app., Magician. The tune up wiped over 1200 titles of my music in iTunes, also a path of folders with names containing nothing but more empty folders with names. Almost every program I open and run for a short time crashes, also folders and programs are in wrong places, or cannot be located (the nephew, for instance). Up to this time I have always been able to track a problem far enough to resolve it by careful persistence and good luck, but I do not have the tech savvy to solve this one without getting in deeper. I have run disk utility saveral times and always get variations of this:
ACL found but not expected on
"private/etc/resolve.conf"
"private/etc/raddb/sites-enabled/inner-tunnel"
"private/etc/rabbd/sites-enabled/control-socket"
     Also, after four years of intense daily use it is cluttered with much junk, and every app that I was curious about, and I am a very curious guy.
   So I know my limits, (and now my nephew). I dumped my pc for a Strawberry iMac a few years ago, and so far every problem I've encountered, or brought on myself, the Mac has resolved with its own inner elegance - in spite of my novice bungels - and now I honestly feel ashamed, in addition to the need to apologize to a machine for allowing a peasant into the Royal Grounds - so I am calling the Wise Ones in for this one.
   Crazy, I know, but to me a Mac represents something far beyond the ordinary input ➛ process ➛ output title/function customarily assigned to a machine - I sense an odd kind of morality involved, one that I need to respect.
    So, these are my reasons for wanting to do a clean install, correctly.
        Thank you, Truitt
