Cd/dvd rom fail after the mountain lion installation

Recently, I installed os (the mountain lion) on my 2009 mac mini. Data CDs and DVDs are available to see but not working(internal super drive). also every audio cd is not recognized at all. I tried to downgrade os to lion but it does not work too. Therefore, I re-installed ML and wait for Apple's updates.
Some update patches I downloaded a month ago was working good but it became dead again after installing other updates.
I hope Apple staffs would take care of this issue because many customers have purchased mac for its safety, innovation and faithful care.

No.
You just need to show the update again.
Go to your account and "Show hidden purchases" or something like that.
You can't delete it.

My dvd quit working after installing mountain lion

It was working fine before I installed Mountain Lion. It took the disk in and then ejected it. Now it acts like it is completely dead - like something just turned it off. I've never used the drive that much. It's a mid to late 2010 aluminum iMac.

Tried alot of things, but it finally started working after resetting the SMC controller - go figure...

Why is video playback continually stuttering after the Mountain Lion 10.8.2 update?

Since updating to Mountain Lion 10.8.2 video playback in iTunes and QuickTime is unwatchable. The video stutters constantly then plays catch up to the sound. I'm running a 2011 Mac Mini i5 2.3 GHz and 8 Gb of RAM. Anyone know how to roll back the update to a working version of Mountain Lion?

Hello, you'd have to reinstall 10.8.0 or 10.8.1, but...
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
http://support.apple.com/kb/PH7029
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab of Activity Monitor, are there a lot of Pageouts?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

How do you update to the new Java 10.7 after the Mountain Lion upgrade?

I recently downloaded the OS X Mountain Lion, I need the Java version 10.7 for gaming purposes. When i go to Java preferences the latest version is Java SE 6, so I tried to do a "software update" but there is no update available.

While we all have MacBooks in this forum most of us don’t run Mountain Lion. There's a Mountain Lion Support Community where everybody has Mountain Lion. You should also post this question there to increase your chances of getting an answer. https://discussions.apple.com/community/mac_os/os_x_mountain_lion

Where to find OS X Lion after the Mountain Lion release?

I have an old MacBook Pro at work, and it's compatible with Mountain Lion. Currently it's running Snow Leopard, but I'd like to upgrade to Lion. Where can I find the download? Since Mountain Lion was released, Lion disapeared from the App store...

If you need to purchase Lion call 1-800-692-7753 or 1-800-676-2775. Ask for a Sales Representative. They will check your Apple ID, and email you a code and instructions. The cost is $29.99 (as it was before) plus tax. It's a download.
Lion System Requirements
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Some features require an Apple ID; terms apply.

Why is my Macbook Pro very sluggish after the Mountain Lion update?

It's quite frustrating being as this is my first Apple laptop. I figured that it would be easy to update these things.
I was using the prior OS and it worked just fine. Now my Macbook is just as slow as the HP laptop that I had to retire.
I'm using OS X Version 10.8.1
Processor: 2.3 GHz Intel Core i5
Memory: 4 GB 1333 MHz DDR3

With only 4GB of RAM, how much do you have devoted to the virtual machine running under Parallels? Even if it's a small amount, it's going to make page outs and swaps used very high. From my perspective, 8GB of RAM is the 'sweet spot' for running Mountain Lion.
I'm assuming that you've a 15" mid-2010 MacBook Pro? If so, you can speed things up by installing the maximum 8GB of RAM. Go RAM shopping at Crucial or OWC.
Other than upgrading your RAM, the only thing that you can do to speed up your machine is to install a SSD. You can also check the SSDs at Crucial and OWC and decide if one is right for you.

The mountain lion installer won't let me install on my Macintosh HD

I've downloaded the installer for Mountain Lion, but it won't install to my HD. I use a separate USD drive for Time Machine, which I ejected before trying the install (it wouldn't work before I restarted after trying with the USB drive attached).

What are the AdditionalEssentials.pkg included in the Mountain Lion installation disk?

I have done a clean install of Mountain Lion on my 13" MBP early 2011 and noticed on the install disk under Packages Folder there is an AdditionalEssentials.pkg andw wondered what are these additional essentials and wheather I should install it or not?

Thanks Templeton Peck. It helped a great deal

After the Mountain Lion 10.8.2 upgrade my system is VERY slow, online connection down miserably. WHat has happened and how do I go back to 10.8.1?

Upgraded my Macbook Pro tonight to 10.8.2....horrible move, internet connection is now a slow crawl. Was very fast before upgrade. IF no known fix how do I go back to 10.8.1?

I had the same problem. My solution was to reset the SMC on my 2010 Macbook Pro and now my internet speed is back to normal.
To reset the SMC, shut down the computer completely. Then hold SHIFT+CONTROL+OPTION on the left hand side of the keyboard AND the Power key for at least 2 seconds. Release all the keys, then repower the laptop normally using the power key.
Hope this helps.

I try to reedem the Mountain Lion after I start downloading nothing really happened and I can use my redeem code again?!

I for the redeem code and everything from Appl. After I try to downlaod the mountian Lion but nothing really happened and I can not use my redeem code anymore. I could not find the file in my download folder either??

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
The Mountain Lion installer is 4 GB and takes a while to download. When the installer finished downloading it usually opens and presents itself for you to approve the installation of hte operating system.
If the download did not occur, you should be able to download the installer from the Purchases pane of the Mac App Store.

2008 iMac won't turn on after Mountain Lion installation

I have a 2008 iMac with 6GB of RAM that was running on OS X 10.6.8 perfectly. Tonight I upgraded it to Mountain Lion. After the installation, my machine was running slower and a little choppy, especially when first opening programs, even though it meets all the requirements for Mountain Lion. After about an hour or two of running like this, I was standing away from the computer for a minute when I saw a flash come from the monitor. I went to it and the screen was black. I thought maybe it had went to sleep, but nope! It was completely off and would not turn back on. No lights or sounds come on at all. There was no power outage or anything, and all other devices plugged into the same surge protector were working fine. I tried plugging it into another outlet and still had no luck.
Any insight onto what caused this? Is it most likely a power supply failure, and could this have been caused by the Mountain Lion installation? Considering I've had this computer for almost 5 years and this has never happened before, it seems obvious that this contributed somehow.
Any advice would be appreciated. I'm going to try to take it to an Apple store soon, but the earliest appointment is a few days away.
Thank you!

Welcome to Apple Support Communities
It's quite possible that the power supply failed. The failure is difficult to be related with OS X Mountain Lion, so I would discard that. In some cases, it's normal that you experience slowness after installing a new OS X version because Spotlight indexes the hard drive.
The best you can do is to take it to an Apple Store or reseller so you can get your Mac diagnosed. Now we can't do anything else apart from thinking that is a power supply issue

How do I get a copy of the Mountain Lion OS that I can use to recover?

How do I make a disc image of my Mac Mini HD that id bootable and has the operating system with all the programs, settings and data. If I need to replace a defective hard drive it would be good to have an image on a USB flash drive to restore previous settings and the operating system -- Mountain Lion, 10.8.1. I have been told that TimeMachine does not make a true disc image. I want a "hard copy" of the operating system that does not require an internet connection.

Unfortunately, the link for getting specific hardware versions has disappeared. So basically:
Get yourself a spare hard drive freshly erased or with a freshly erased partition of around 8 GBs or more.
Boot to your Recovery HD. Select Reinstall Lion from the main menu.
From the beginning screen select your spare partition/drive as the target destination then begin the download.
At the end of the download you will observe an Install button for you to click. Now this is important - as soon as that gadget appears you must abort the installation process. There are only two reliable ways to do this quickly: a. yank the cable for the drive from the computer; b. pull the power on the computer - shut it down quickly.
This will result in your finding a folder on the drive that contains InstallESD.dmg that you can now use to create a bootable USB flash drive installer based on the special build for your model. Use it until the next public release of Lion appears or you move on to Mountain Lion.
If you do not stop the download process immediately upon its completion you will end up with an installer that always boots to a non-functioning installation progress window instead of the normal main menu.
Make Your Own Mountain/Lion Installer
1. After downloading Mountain/Lion you must first save the Install Mac OS X Mountain/Lion application. After Mountain/Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Mountain/Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
3. Locate the saved Mountain/Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the content of the InstallESD.dmg disc image to the flash drive as follows:
Double-click on the InstallESD.dmg file to mount it on your Desktop.
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the mounted disc icon from the Desktop into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable installer that you can use without having to re-download Mountain/Lion.
Note: The term Mountain/Lion used above means Lion or Mountain Lion.
As an alternative to the above you can try using Lion DiskMaker 2.0 that automates the process.

Other way to download the Mountain Lion

Is there any other way to download OSX Mountain Lion, because my Internet connection is very slow and when i pause the download and when trying to continue later, it is starting again from the beginning. So can anyone suggest with other alternative.

Other than taking your MacBook to some place with a faster Internet connection, or using someone else's computer to purchase and download Mountain Lion and then copying the ML installer to your computer (make sure you log out of your App Store account and delete the Mountain Lion installer from that computer when you've copied it) there is no other way. Mountain Lion is only available via download from the Mac App Store.
Regards.

After installing Mountain Lion my bootcamp partition disappeared

I installed Mountain Lion, and now I can't boot into bootcamp, and there is almost no trace of it to be found on my computer. It shows up only in Disk Utility as "disk0s4", but it's greyed out. It can't be verified or repaired. Is there any way to fix this?

OK I'm wrong. You have a 30GB partition that's unallocated to either Mac OS or Windows (i.e. it is free space), so there is a story here that hasn't been told because the Mountain Lion installer would not do this. I'm going to guess at some point in time you used Disk Utility to delete a former Windows partition and make a new FAT32 partition that was bigger, and then reinstalled Windows. Or something like that...
The MBR partition entry for Windows has the wrong partition type code (0c instead of 07), and he partition isn't marked as bootable. So that's one problem.
Assuming nothing is wrong with the Windows bootloaders, the simplest way to fix this problem is probably Camptune or maybe iPartition (but I haven't used either to fix this particular problem and I'm not sure how smart they are). Neither are free.
The next easiest, which is free and easy but there is no GUI for it, is to use fdisk from command line to fix the above problems with the MBR. The notes in [ ] explain the steps, you don't type them, just the first part of each line, followed by enter/return.
sudo fdisk -e /dev/disk0
e 4     [edit 4th partition]
07      [partition type 07 for NTFS]
n       [edit in LBA mode]
875673600    [starting LBA for Windows partition]
101099520    [size in sectors for Windows partition]
flag 4
quit
y            [confirm writing the MBR to disk]
Reboot your computer.
This instructions only work for the specified disk, for others to replicate, you have to know the correct start LBA and number of sectors, which can be found from either the earlier gpt or fdisk commands listing the partition entries.

Where can I find my mountain lion installer included with 2012 mac mini

I just bought a 2012 mac mini and I want to install mountain lion on an SSD that I bought separately. Where can I find the mountain lion installer file to create a bootable USB install drive? When I go to the mac app store, mountain lion is not listed in my purchases and when I try to buy it, it says "We could not complete your purchase. OS X Mountain Lion is not compatible with this computer." It's already installed on the mac mini, I just need the installer file so I can install it on my SSD.

You might be able to simply boot into the ML Recovery HD, select Reinstall OS X and point to your SSD drive. You won't capture the InstallESD.dmg file to create a USB thumb drive installer.
OR.... to create a USB thumb drive of your pre installed ML, you would need to redownload Mountain Lion then grab the InstallESD.dmg file and create your USB thumb drive.Here is how I've done it using Internet Recovery to get my pre installed OS X.
Attach a USB external drive to your system. Formated as Mac OS Extended (Journal) and GUID partition table.
Restart using Command+R+Option to boot into Apple's Recovery HD. This will get you the original version. Or just Command+R to boot into your ML Recovery HD.
Select Reinstall OS X from the OS X Utilities menu.
You will have to watch the download. After it completes and your system restarts, at the black screen disconnect the external USB drive.
After you are back to your current desktop, insert the external USB drive. There should be a single folder on the drive called 'Install Data' (I think). Find the InstallESD.dmg file and copy it to a folder on your current system (Downloads, for example).
Follow any of the internet instructions to create a ML USB thumb drive.
I tried this method, and while it did get me the installer image, when I restored it to an external and tried to use it to restore a Late 2012 Mac Mini, I got the same "No" symbol I did with other ML installers.
Here are some screenshots of what was loaded onto my external before I yanked it, when the screen turned black durring the restart. The highlighted file is what I restored to my external to use to restore the Mac Mini.
