IMac running hot! After installing Mountain Lion OS

I installed Mountain Lion and I my iMac is running so hot. The fan is running and the whole case is hot. Hot along the whole back side. Has anyone else had this happen? I call Apple Support and scheduled an appt. today to drop off for evaluation and repairs. Just be aware!

I am curious what you mean when you say that "once this process is complete, things should settle back down to normal levels" with respect to reindexing and "NORMAL" temperature levels.
Would you kindly tell me what "NORMAL" temp levels are supposed to be for an iMac Mid 2011 Intel Core i5 2.5 GHz processor with 8 GB RAM or any iMac with which you are familiar?
Here is what my stuff looks like at present. What is 'normal" operating temp?
Thanks.

MacBook Air late 2010 very hot after installing Mountain Lion? Can i back to Lion?

My MacBook Air, late 2010, is very hot and the vans are going too speedy after installing Mountain Lion. Can I deinstalling Mountain Lion and returno to Lion? What are the steps for this deinstallation? Thank you.

Technically, there is a way, but it is definitely not something I would recommend, as downgrading isn't usually supported/encouraged.
I found a website that has instructions but it clearly states it's not for the inexpert, so proceed at your own risk. Also, I don't think you can download Lion from the AppStore anymore?

Safari runs slow after installing mountain lion

Safari is running very slowly since I installed Mountain Lion. Any suggestions about why this is happening or how to improve the speed?

I ordered something from a website I haven't used before, and it was very slow, but I don't know if it's that website or safari. Safari is the only browser I use.

Mac Book Pro i7 late 2011 Running Slow after installing Mountain Lion

Hi All,
Is anyone else experiencing the same issues, since I have updated to Mountain Lion last week my mac is now running alot slower than before on startup, closing down and when opening and shutting programs / apps.
Would it pay me to upgrade to 8GB ram?
Thanks

HT1338 Why is my MacBook Pro running so slow after installing Mountain Lion 10.8.

Why is my MacBook Pro running so slow after installing Mountain Lion 10.8. I have restarted, created more free space on my hard drive and run disk utilities. Simple operations result 20 seconds or more of the spinning wheel. Some are so slow that the operation does not happen at all. Itunes music cuts out during operations.

Check out this article by Thomas Reed for help http://www.reedcorner.net/understanding-upgrade-nightmares/. Also, make sure all apps are compatible with Mountain Lion using www.roaringapps.com. Do you have any antivirus installed? Make sure all apps are updated as well.

Serious wifi problems with iMac after installing Mountain Lion

After installing Mountain Lion, I'm experiencing serious trouble with wifi. I noticed that some people had this before with Lion. Can anybody help to solve this problem or should I downgrade to Mountain Lion?
Please help
Thanks in advance!

Thank you for the information Arizonadonn! I'll install 10.8.1 this evening. I really hope you're right after having connection troubles for almost a month now .
If this solves my problem, you'll be my hero !

Ethernet connection issues after installing Mountain Lion

After installing Mountain Lion I can't get my iMac to connect by ethernet. It says that no cable is connected. The cable/connection is fine. When I plug in my MacBook Pro running Lion, the ethernet connects just fine.

same exact problem. in fact, my iMac24 (2009) worked flawlessly until I installed the latest update to Mountain Lion. I then checked my MBAir (2011) and it too has a problem when using the USB/Ethernet adapter. Neither can get an ethernet connection. I deleted my network preferences and rebooted my machine, played around with my Ethernet switch and even reboot my gateway/router. I've never had to do any of this to my network until Mountain Lion. Wireless is the only thing that continues to work on both machines.

Microsoft Word Intermittently Crashing After Installing Mountain Lion

After installing Mountain Lion (10.8), Microsoft Word 2011 (v 14.2.3, currently the latest update) is intermittently crashing. This is not the error I have seen reported elsewhere where Word crashses on start up. Rather, it starts fine, runs for a while, then suddently freezes and gives an error message. Unfortunately I do not remember the full error message, but it stated something like "Microsoft Office cannot write to the hard drive..." I was prevously running Microsoft Office 2011 and had no problems until upgrading to Mountain Lion.
So far I tried repaired disk permissions, both via the disk utility application and by restarting while holding down the option key to boot into disk utility directly. This did not solve the problem.
I also checked the activity monitor, because after crashing the computer starts running very hot. The activity monitor shows a process called "mtmd", which is using 50-80% of the CPU. This activity seems to persist until the computer is restarted again.
I also checked fonts in Font Book, but there appear to be no duplicate fonts, which I thought might cause a problem in Word.
Any suggestions would be greatly appreciated.

Hi there,
I've been getting the same error message for teh last few days. Word and Mountain Lion seemed to be playing well together until the last MS update (now running Word 2011 14.2.3). Fans go into overdrive and always a reboot required. Additionally, my DOCX is gone from where it was saved and in place only a word.tmp file remains. Sometimes I can open the temp file and recover all of the data but sometimes not. Luckily Time Machine has saved me on both occasions when the tmp file wouldn't open.
Excel and Powerpoint are currently running very smoothly (in fact I dare say better than previously).
I've tried running the DOCX from local drives and two external drives all with the identical results. However, after this occurring for the nth time I noticed that it seems to occur when Time Machine kicks in. I'm presently testing it with Time Machine turned off and all seems ok. Though it does kind of defeat the purpose!

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install.

Ive just upgraded my late 2009 macbook, and things are not working properly. First of all, when I started the computer first time after installing Mountain Lion, some message advised me that some files were impossible to install. Once I wrote my password, and for now on, everytime I start the session, another window advise me that "Java SE 6" is missing, due that, the computer can't run some "CS5Service Manager". If I try to install it, the download ends with an error. If finally, you skip the istallation, you arrive to the dock, but the menu bar at the top of the screen doesn't show up.
In addition, my trackpad doesn't works either. I can move the arrow but i can't click anywhere, probably because the option of clicking by touching is disabeled and I can't performance a regular click.
I'll be very glad if someone know what the heck is happening with my computer. Anyway, I'm going to the genius bar next Saturday. Thx!

We're sorry.
We can't find the article you're looking for.
Please return to the Apple Support homepage.
Sigh.

Can No Longer Get Camera Photos After Installing Mountain Lion

After installing Mountain Lion, I am no longer am able to see pictures from my digital camera thru the USB port. This camera has worked for years with my iMac, but not anymore. Anybody else having this issue after installing the newest system?
Dick

Paul_31:
I have not tried to import the photos directly into iPhoto. However, I did remove the SD card from the camera and plug it into a USB card reader, and my iMac would NOT read the photos that way either. I took the camera and plugged it into my Win. 7 laptop and the pictures showed up nicely, so I know the camera and the card are Ok. My iMac has been working strangely since I installed Mountain Lion. I'm getting lockups using iMovie too.

After installing Mountain Lion two drives on my network cannot be accessed. I am using Parallels to utilize QuickBooks ERP. The programs and data are on the drives that I can no longer access. Suggestions?

After installing Mountain Lion on my Mac Book Pro, I can no longer access two shared drives. Diagostics cannot solve the problem. I am using Parallels to run Qucikbooks ERP on these shared drives. How do I get my Mac to see these drives and access them?

Don't know what to tell you, but I also have an AEBS-Gen5 with a MBP Retina and Mac Mini using WiFi. Both are running Mountain Lion and I don't have any WiFi connection issues. Two iPhones in the household use WiFi with no issues along with a printer and 2 Windows 7 laptops.
First thing I would try is to shutdown all computers connected to the AEBS. Then power off the AEBS and finally the cable/DSL modem. Then reverse the order and power on the cable modem, wait for all the lights to be solid, power on the AEBS, wait for the light to show solid green; then power up a computer that uses WiFi.
If the above doesn't work, you might try repairing permissions via Disk Utility. If that doesn't help maybe a PRAM reset would work.

After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

We've had several instances where we have had to run chkdsk on arrays with over 1m files. Average completion time is approximately 72 hours. The maximum downtime window they have available is the 64 hour weekend window. File sizes and number of files were
much smaller then than they are now.
The idea, in theory, was to use VHDs to compartmentalize the data into smaller volumes which could be more easily managed. It would also improve performance when transferring these compartments of data as they would use sequential read/write rather than
fragmented/random. This idea was never fleshed out in entirety, they don't split data up into little containers, but simply into big ones per project. Hence the 11m files in one container that I am currently trying to diagnose.
Some other important facts: The VHD in question is mounted in B:/project/ as this server also allows remote workers to log in, but they are restricted to see only data in E:. Disks A-D are hidden via group policy.
Update: icacls is failing on a large number of files within this dataset. I counted the path characters to ensure it wasn't the 255 character limit I was encountering and verified that the paths being blocked are only about 150 characters long. Once it finishes,
I'll have to try taking ownership and then re-running it. At this point I still have no idea how long to expect. I'm running out of time as the environment will be in use again at 9AM tomorrow morning.

My wifi is very slow after installing mountain lion on my Mac book pro

My wifi is very very slow after installing mountain lion on my MacBook pro.
What can I do?

Ha ha, I misread that as "My wife is very slow after installing mountain lion on my Mac book pro"
BTW on my MBPro (late 2009 with max RAM) Mountain Lion runs very well with no slowing down.

After installing Mountain Lion my mouse won't scroll

After installing Mountain Lion my mouse won't scroll up or down. It will, on occasion, scroll left.

Which mouse do you have? If it has a mechanical scroll ball on the top then it's simply dirty and needs cleaning. However if you are using Magic Mouse then please click iMac SMC and PRAM reset and do both resets 2x.

After installing Mountain Lion, my Time Machine won't back up ... says the sparsebundle is in use

After installing Mountain Lion, my Time Machine won't back up ... says the sparsebundle is in use

Standard problem in ML.. apple do not seem to want to recognise.
Reboot the TC .. if that fails restart the whole network in correct order.. modem.. router/TC... clients.. with 2min gap.
There are other suggestions like changing the password.. all they do is the same as reboot.
Read C12.. most quoted Q in pondini website history. This is asked 10 times a day.
http://pondini.org/TM/FAQ.html
Here is another way to get a useful utility in ML.. rather than toyland version.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.
