Question about Mountain Lion on iMac 27

I recentely installed Mountain Lion on my iMac, and after the computer restarted and everything. When I click on an icon, it doesn't go into the program or the apple menu too. What can I do to solve this problem?

That is checked (of course); however, I just actually tried the wireless mouse that came with the iMac and that works using a click - it does not work with my wired third party (Macally) USB mouse which is what I use (I do not care for the "un"ergonomically shaped Apple rodent). And it used to work with my Macally mouse, so something was definitely changed with the Lion release. I actually sent in a bug report for "loss of functionality" - didn't get me anywhere, LOL.

General question about Mountain Lion

I've kept clear of Lion on both my MACS because of all the "bad press" it got, I'm still running Snow Leopard on my MACS and I've never had a day of problems with either. Also I run Logic Studios on both my MACS and didn't want to chance having issues with interface compatability, lack of drivers and such. My question is kind of simple and for better or worse comes down to opinion, what is the general feeling about Mountain Lion? Is it a big improvement over Lion? Is it more stable with less bugs? Any issues running Logic? I'm "playing with the idea" of upgrading but I want to do my research first. If Mountain Lion is not a big improvement over Lion or if people are having issues with running Logic I'm going to stick with SL.
Thanks for your opinions in advance.

Be cautious about listening too much to replies you're likely to get. These sort of questions in a place like this are like magnets to people who are having problems and want to complain about it. You're likely to hear some horror stories that don't represent the majority of cases.
ML has been excellent so far for me, faster than Lion and no serious bugs I've discovered so far. But if you upgrade, be sure to do your homework: backup, check compatibility of all your software (including things like printer drivers) and repair the hard drive with Disk Utility before installing.

As the others have stated, you're on Mountain Lion with 10.8, anything. But you can check your version of the software by going to the apple in the upper left corner of the screen and clicking it and selecting "About This Mac". That will open a box that shows your software version. Once there you can click on "More Info" that will tell you everything about your specific mac configuration.

Attempting to install Mountain Lion on iMac running OS 10.6.8 produces the message that ML cnnot be installed on the int. HD because it is used by Time Machine. It is the int. startup drive. What now?

You may have a folder named Backups.backupdb at the root level of your startup disk. You cannot find it with Spotlight. Just navigate to your startup disk (usually named "Macintosh HD") and drag Backups.backupdb to the Trash.
Is your startup disk partitioned? If so this may be applicable:

HT201272 Under purchased items in the APP Store, it say that the item you have requested is currently not available in the US store. The item in question is Mountain Lion OS X

Under purchased items in the APP Store, it say that the item you have requested is currently not available in the US store. The item in question is Mountain Lion OS X which I have already paid for. Any ideas to retrieve this?

When you submit a podcast you should get an email acknowledging the submission. If you subsequently submit it again you will get an error message saying that it's already been submitted.
It then has to be assessed by a real person, which can take some time - a couple of weeks seems to be common, but it can be longer: however since March seems an unreasonably long time.
When it's accepted (or rejected) you should get an email saying so, in the first case giving you a link to the Store page.
More than that I can't tell you: obviously I don't have access to the inner workings of the Store. You could try asking Support, but I have to say you probably won't get a helpful answer. Go to http://www.apple.com/support/itunes/ - click on 'Other iTunes Store Features' in the list and then on 'Podcasts'. You will see a link to either 'Express Lane', which will guide you eventually to some contact options, or you may see a link to email them.

Since I installed Mountain Lion, my iMac has shut down after 15-20 minutes. I have adjusted screen saver, shut down time, and sleep after. Nothing seems to help, any ideas?

As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.

HT1758 About using OS X Mountain lion on iMac

I bought an iMac in november 2010, Can I update my iMac with OS X Mountain Lion? I live in Sydney, Australia.

Upgrade to Mountain Lion

Mountain lion on iMac compatible with retina Macbook pro?

My late 2012 13" Retina Macbook pro running Mountain lion 10.8.4 is suddenly paralysingly slow due to kernel_task hogging my CPU. I have not been able to find a definite solution to this problem yet, but I am guessing some software installed is causing the sudden meltdown.
I ran Apple Hardware test 3 times.. the first time it spotted an error "4SNS....ICOR..." but after cleaning out the vents on my mac, it hasn't shown up again.
Now I read online that a clean fresh install of Mountain Lion may solve the kernel_task problem... however my rMBP is so slow, that I cant even manage to open the app store on it.
So my questions are:
1) Is there any solution to fixing the kernel_task hyperactivity on the rMBP that I am not aware of? (Tried rebooting, resetting SMC, PRAM multiple times, repairing disk, repairing disk permissions -- all to no avail - the problem recurs after a short period of normalcy and then goes back to becoming unusable)
2) I have a 2011 iMac... Can i download mountain lion on it via the app store, make a bootable disk from it, and use it to perform a fresh reinstall of mountain lion on my 2013 rMBP? Can OSX downloaded on app store of iMac be used on a totally different device like rMBP? Should I be worried about device incompatibility, drivers going out of whack, etc? Or is the mountain lion installer a global software and can figure out the device make on its own and install itself correctly?
Thanks
Regards

1. That's a known problem in portable Macs. There's a fix but you have to follow the steps carefully > http://www.rdoxenham.com/?p=259 Make a backup of your files before doing this.
2. The 13-inch MacBook Pro with Retina display was launched with a special OS X version, but as the most recent OS X version is 10.8.4, you can download OS X Mountain Lion from the iMac and use it in the MacBook Pro without any problem. Just download OS X Mountain Lion in the iMac and use Lion Diskmaker to burn it to a USB drive or DVD > http://liondiskmaker.com

How to download mountain lion on iMac that already have it?

I have late 2012 iMac with MacOS 10.8.2 and I'm want to fresh reinstall my OS (no ask me, why, please ).
I looked in AppStore but saw only "Buy" link, not "Install".
So I don't understand - I need to pay for it? Why? I already have it installed on my computer.

My pleasure.
Here's a link to read about Internet Recovery. You'll see where you have to use it for new hard drives.
OS X Internet Recovery
If you happen to encounter a situation in which you cannot start from the Recovery System, such as your hard drive stopped responding or you installed a new hard drive without OS X installed, new Mac models introduced after public availability of OS X Lion or OS X Mountain Lion, automatically use the OS X Internet Recovery feature if the Recovery System (Command-R method above) doesn't work. OS X Internet Recovery lets you start your Mac directly from Apple's Servers. The system runs a quick test of your memory and hard drive to ensure there are no hardware issues.

Unable to install mountain lion on iMac

Hello
I bought mountain lion and installed it with no problems on my macbook pro. After that i wanted to install it on my iMac(intel) too, but here i fail repeatedly.
Mountain Lion gets downloaded, installation dialog appears, everything seems normal except for duration: Once the installation starts it says "Remaining time 3 minutes" and thats it, after three minutes the whole process ends, no reboot, no error message, no nothing.
On my MBPro it took about 50 minutes (estimated 30 minutes and then another 20 minutes) - but the installation succeeded.
On my iMac it says from the beginning that it will take only 3 minutes.
I disabled time maschine, no user except admin user is logged in.
What can i do?
iMac was bought about last summer, i am within my 1 year warranty - so my iMac should not be too old.
Regards

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If 10.7 or more, reboot holding CMD+r down to boot from the Restore Partition, use Disk Utility there to repair the Disk, reinstall may be needed if errors were found.

Mountain Lion on iMac with no SSD - why is Power Nap forcing my computer to sleep?

I have an iMac purchased in mid-2011. It has no SSD. So why is it going to sleep when tasks are still running? If I'm encoding a video in HandBrake, downloading files in Firefox or Chrome, etc...the computer goes to sleep, despite the fact that it's still doing something. Why is this? If my iMac is not Power Nap capable, shouldn't it use the old method for determining whether or not to go to sleep? Why can't we choose between Power Nap and previously functioning sleep behavior?

I am unclear on how that will help. It is a link to a post from a user on a non-Apple website whose first and only post is about how this problem exists. And I assume if you're referring to the Apple Discussion thread that other post links to, you would have just posted that link instead.
If you intended to link to that other Apple Discussion thread, from that discussion thread, Apple told one user, "Apps need to use power assertions while engaged on activities that should not be interrupted and we are working to evangelize this." meaning that Apple realizes they haven't done a good job of letting developers know of this; and that was from October 18, 2012, nearly 3 months after Mountain Lion's release date and I believe nearly 8 months after the first developer preview. So by Apple's own admission they haven't done a good job regarding this issue.
However, that does explain why Mountain Lion is behaving the way it did. Both Apple and developers dropped the ball on this given that major apps (Firefox, Chrome, etc...) still don't implement Apple's new method of power saving.
