Imac 27" 2012 Mountain Lion running very hot

Please help. My 27" IMac running very hot, especially top left corner. Is there a fix.
Tony R

A couple of things. First, do you know what the internal temperature are? if not, look into getting the widget istat from slayer. It will show you something like this:
You can monitor the fan speeds and temps.
The iMac should speed up the fans in relation to the temperatures against a profile determined by Apple. If for some reason, your fan speeds are low and the temp is sitll high, you may need to reset your SMC. That is the shutdown, unplug, wait, plug it back in, restart maintenance proceedure.
If everything is working properly and you still don't like the temperatures, you can download SMCfancontrol. This applications allows you to speed up your fans manually or set higher minimums.
Lastly, iMacs to get hot and are designed for it. Apple wants to keep the fans speeds down so the system is quiet. If you play lots of games, or doing a lot of GPU/CPU intensive work, it is normal for the chips to hit 70C at the case and the fans to be clearly audible. If you were expecting to work the machine hard but the aluminum backside to be just warm, that won't happen.

Mountain Lion Running VERY SLOW on Late 2009 iMac

Specs are all good. There's enough disc space, memory etc... Not too many start up items...
But STILL... My system is BUGGY and VERY SLOW!
I've done a clean install and to no avail... I am constantly getting the spinning wheel with every action I take.
For now, all I can do is be extremely patient and not keep pushing the system... I let it do its thing.
Something is not happy.

Thank you for the repy ETRESOFT!
Not sure why the screen shots aren't showing up? They even came up on iPad while viewing your post? Sorry about that.
Okay... After running your diagnostic program, (THANK YOU AGAIN) here's what we find...
It looks like there's a S.M.A.R.T. failure. (SEE BELOW)
I'm not sure if I should completely wipe the hard drive, attempt utility disk repair and reinstall everything? Would it benefit?
Last week when I was prepared to install Mountain Lion for the first time, I called APPLE Support and they advised me to do the following for a fresh & clean install:
Completely erase the iMac hard drive.
Download and Install a fresh copy of Lion
Set up TEMP USER as default ADMIN
Upgrade to Mountain Lion
Add a 2nd user Chipo1973 with ADMIN Rights
Migrate backup copy of Chipo73 from MacBook Pro onto user Chipo1973 / iMac
Delete original TEMP USER
Not sure if this caused any additional issues?
Thoughts?

Why does mountain lion run hot on my macbook pro?

After up grading to mountain lion my macbook pro now runs very hot!!!

Same problem here,
I used third-party software to manualy regulate the fans, to minimize the "damage". My CPU temp on my MacBook Pro went up to about 75.0 °C (167.0 °F). And the alu-body also gets incredibly hot. For monitoring I used iStatPro.
The application integrates nicely into the system-settings menu and there's very little that can do wrong.
I set my Base fanspeed to 3000 RPM
Lower threshold to 40.0 °C (104 °F)
Upper threshold to 70.0 °C (158 °F)
I don't really see this as a long-term fix, but more as a messure to save my hardware.
Hopefully Apple will look for a fix. I really whished I didn't need this, but it's either this or a scorched lap/battery/cpu.
PS.- I think this topic is related to: Battery life dropped considerably on...

My MacBook Pro is running very hot after lion install. Are there any hardware changes that will help? What can I do to get it back to normal?

My MacBook Pro is running very hot after lion install. Are there any hardware changes that will help? What can I do to get it back to normal?

I get the impression that most of the users on older hardware experiences similar temperature issues on Lion for a long time now. Awaiting for confirmation from the original poster.
In the meantime I'm just cautious with regards to pushing the machine to such extreme temps, since something tells me such behaviour which includes monitor flickering and the likes is nothing but abnormal for any type of use...
Any clues if 10.7.5 does anything on this? If not I'm afraid i see myself going back to SL for good...

Welcome to the Apple Support Communities
Power Nap only works with Macs with flash storage, and it requires a firmware update that it's only supported on a Late 2010 or newer MacBook Air and the MacBook Pro with Retina display

Can someone please tell me if the late Dec. 2012 iMac comes with mountain lion or something different? thanks

Desktop is running very hot

Hi. My desktop (iMac 21.5" from 2009) is running very hot since I downloaded Maverick OS X. Is there a way to find out if it is running TOO hot or if it's ok?

Does the computer seem to heat up when doing a particular task or is it an "all the time" thing?
Can you answer the following questions for us?:
1) Are you running any anti-virus/internet security applications?
2) Are you running any "cleaning/tune-up/optimization" applications?
3) Any peer-to-peer or torrent downloading software?
4) Any third-party disk backup software that came bundled with an external hard drive?
5) Any online backup scheme other than iCloud (Carbonite; GoogleDrive; MS One Drive)?

Mid-2010 Macbook Pro running very hot

Hi all,
My mid-2010 Macbook pro is running very hot. On average CPU is 61-70 degrees Celsius, sometimes even more. I'm pretty bad at having lots of chrome tabs open and heavy multitasking, but even when I'm not temperature still ends up very high and fan rpm can get to over 6000. Heat seems to be concentrated to the lefthand side of the touchpad (battery area?). I'm running 10.9.3.
Current stats below from iStat pro widget (smcFanControl concurs with these temps), with only the following pic's activity running. Laptop currently balanced on two books (so airflow around the sides) which are in turn on my lap.
I have tried reseting the SMC with the shift-control-option-power method but it doesn't seem to have worked - instructions said to press and hold this, then release, then press power again to boot, but laptop boots up from this combination anyway.
Am I just doing something wrong or will this be an expensive trip to the apple store to fix?

Hey happyhaskins,
If you are having an issue with your MacBook Pro running excessively hot, I would suggest that you troubleshoot using the steps in this article -

Thanks for using Apple Support Communities.
Happy computing,

I have a free agent desk 500GB external hard drive. Since updating my iMac OS to mountain lion recently, it will no longer backup, stating "an error occurred while creating the backup folder". Can anyone help me with this?

I have a free agent desk 500 GB external hard drive. Since updating my iMac OS to Mountain Lion it no longer backs up through Time Maching like it did in the past. Now, after completing its work it says, "Unable to complete backup. An error occurred while creating the backup folder." I cannot find any sites that help me fix this. Do I need to purchase a new external hard drive?

Hi Aaron,
Have you looked through Pondini's extensive TM help site?

Think about it for a second. Some Macs come with SSDs, so obviously the OS runs on them...

Is there any Blu-ray Player Software compatible with my iMac OS X Mountain Lion?

I want to watch a Blu-ray Movie on my iMac(OS X Mountain Lion), so I need a best Blu-ray Player Software.

You need third party software, Macgo Blu-ray Player can deal with the work you mentioned. As for the Mac Moutain Lion(10.8), I check their website and it is said that the Mac OS 10.8 are supported.
Refers to their product page: http://www.macblurayplayer.com/features.htm

SQL 2012 DBCC CHECKDB Run Very Slow

Does anyone experience this? SQL 2012 DBCC CHECKDB runs very slow on one of the server. I monitored the server and it seems DBCC CHECKDB does not hit the disk hard enough.
It can read 100 mb per second on of my slower server, but on this particular server, it only read 1 mb per second. I saw parallel processes, but it just not read disk hard enough. I am curious what causes this? There is no user using the server when I run
DBCC command. The full database restore took 3 hours, but DBCC CHECKDB took more than 11 hours. Thanks for any input.
Lijun

Hi,
Have you made the change of 'cost threshold for parallelism'? The default value of this is 5. Increasing the cost threshold for parallelism would cause most of the queries including CHECKDB to not execute parallel and hence will tend to
take time to complete. This could be one of the issue contributing to the CHECKDB slow run.
Also, please check if the antivirus is checking SQL Database files:
http://support.microsoft.com/kb/309422
Here is a good article on CHECKDB time taken to complete.
