Mountain Lion via clean install (USB) but wont read dvd/cd

I did a clean install of my mountain lion on my Mid-2009 MacbookPro 15". Everything was running fine. Until I tried to burn a cd. Thought it was a media issue. So didn't bother burning the disc after all. Then I tried playing an audio cd, the systems thinks it's an empty disc. Next tried to load my Snow Leopard installation disc (DVD), it got ejected too. All i get is the following with all cds and dvd, burnt or blank also the same.
I have tried repairing disk permissions before system bootup and also after system bootup via disk utilities. It didn't fix the problem.
I also tried blowing the superdrive with a camera lens blower. Didn't help either.
What else can I do before bringing it to the Genius bar?
Thanks.

I am lucky to have stumbled upon this thread. The drive was dirty.
I took a membership ID plastic card wrapped a lens cloth over, sprayed some glasses cleaning solution, swipe it inside the drive a couple of times... and voila it worked!

I downloaded OSX Mountain Lion via the App Store but I can't download to my other mac

I downloaded Mac OSX Mountain Lion via the App Store. My understanding is that you can download it on up to 3 machines?
I have downloaded it to one iMac and one MBP but have one more to do. I've accessed the App Store with my admin logon on my last MBP to download it but can't seem to find it in my purchased history to do it.
I can go into iTunes into my account and then purchase history where it's recorded, but there's nothing here about how to download it again?
Any advice greatly appreciated.

Log into the Mac App Store using the EXACT same Apple ID as before when you first purchased ML, and in your Account look under "Purchases", where you can download it again.
Hope this helps

Mountain lion won't install - downloads but says file is corrupt

I have purchased mountain lion osx from the App store and downloaded 3 times. Each time I try and install, it says the download is corrupt and that I should uninstall/try again. Any advice?
Trying to upgrade from 10.6.8 install of os on:
Model Name:          MacBook Pro
Model Identifier:          MacBookPro6,1
Processor Name:          Intel Core i7
Processor Speed:          2.66 GHz

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether your problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Failed TM backup after Mavericks upgrade via clean install. Nothing works incl. "tmutil" command. The time points appear but not clickable.

I upgraded to Mountain Lion via clean install. Restoring my data via migration assistant failed. Then I tried Time Machine. Altough I can see all backup time points no one is active. Then I tried to inherent and to associate the backups to the "new" disk, but it didn´t work.
Thanks in advance

Hit the nail on the head Eric, I have quite a lot in there due to system age, so turned them all off and had a nice fast system returned with no hanging.
so definately something in the startup group and i will try each at a time and see where the problem comes from..
Looking at more logs my guess is the problem will be with one of -
sabnzbd
sickbeard
both of which starting on login, both using databases and im seeing sql errors on startup...
more info when i have enabled/disabled some more apps.

HT1553 I want to do a clean install of Mountain Lion. Can I do this without a DVD version of the OS, and can I restore only specific things like iPhoto and iTunes libraries from Time Machine backup.

I want to do a clean install of Mountain Lion. Can I do this without a DVD version of the OS, and can I restore only specific things like iPhoto and iTunes libraries from Time Machine backup.

Mountain Lion is only available as a download, so there is no DVD to purchase. What you can do is download ML and then stop it from installing as soon as it's on your drive. From there you can make your own bootable ML flash drive.
When your purchase and download Mountain Lion, it will end up in the Applications folder and automatically want to install. Press Command+Q to stop the install and exit. The installer will remain on the hard drive.
1) Right click on the installer and choose "Show Package Contents".
2) A folder will open on the desktop. Drill down to Contents > SharedSupport and double click the disk image InstallESD.dmg to mount it on the desktop.
3) From here you can either burn a DVD, or copy the contents to a flash drive. Personally, I would strongly suggest using an 8 GB flash drive formatted as Mac OS Extended. You will be able to boot to it in about 30 seconds instead of at least 10 minutes off of a DVD, and it will install MUCH faster. Make sure the flash drive is empty, or you've copied anything off it it you need as it will need to be erased.
4) Don't just drag and drop the contents you see in the open disk image to the flash drive. It won't boot that way as it will be missing some hidden files. Open Disk Utility. You will something similar to this:
5) To accomplish the above, highlight either the flash drive's single partition (as I did), or the item at the bottom (Mac OS X Install ESD), which is what you will see with the Lion disk image mounted. It doesn't matter which one you pick. You'll then have the option to select the Restore tab towards the upper right. Drag and drop from the left column into the Source and Destination fields as shown above. If you've already erased the flash drive, you can uncheck the box. Click the Restore button.
You've just made your own bootable Mountain Lion USB Flash drive installer. Once you boot to the flash drive, run Disk Utility first to erase the drive you want Mountain Lion on, then continue with the install.
As far as restoring your iPhone and iTunes libraries, I couldn't tell you. So I wouldn't do any of the above until someone else chimes in with a way to do that after a clean install of ML.

Installed Mountain Lion: Fonts Disappeared In Photoshop But OK In Word

Installed Mountain Lion yesterday. Install went OK.
Was surprised to find a Parallels helper app in Incompatible Software folder, no big deal. May need to reinstall Authentec Truesuite for fingerprint reader but am quite surprised to see my hundreds of fonts disappear from Adobe Photoshop CS6 when I launched it in ML OS10.8 . Any ideas on how to recover the fonts?
The interesting thing is the fonts are all there in Microsoft Word. Thanks.

Even though you can access the outside world via Ethernet cable, you should be able to use wifi - I had no problems when I upgraded.
Try taking your question to the Mountain Lion forum and see if any users there are experiencing similar problems.

It would be easier to just fix whatever is making your machine slow.

Mountain Lion can't install but won't let me quit the installer!

Mountain Lion can't install but won't let me quit the installer! How can I get back to the desktop?

I was having the same problem with my iMac. Couldn't left click with the wireless mouse, i tried all the steps above to no avail. I then tried to use another mouse, this time bluetooth and still had the same problems. I decided to see if my trackpad, which sits in the corner of my desk and never gets used, and then i realize that my cat is lying on top of the trackpad which was causing my problem the whole time.
I hope your fix was as simple as mine.

iCloud isn't syncing them on your phone. You simply added the email account to your phone and enabled calendar and notes syncing with the email provider, and the calendar and notes appear in the calendar and notes apps on your phone. You can do this with Gmail, Yahoo and other IMAP account. iCloud email is just another IMAP account, but syncs notes with Apple's iCloud server just as Gmail syncs notes and calendars with Google's server.
iCloud didnt' set up a non-iCloud account on your Mac. When you check Mail in System Preferences>iCloud, it only creates an iCloud email account. You can also add other email accounts to your Mac by going to System Preferences>Mail,Contacts,Calendars and clicking on the "+" sign on the bottom of the left sidebar. If you added these other email accounts to your Mac before you upgraded to Mountain Lion, these were simply maintained on your Mac after you upgraded.

P.S. The order status in the app shop says - complete - but no download option anywhere.
And when my computer wants to reinstall mountain lion - it says, that this ID did not purchse Lion
What is this supposed to mean? I have to purchase Lion OS as well? or it means mountain lion by this message, but just doesnt see, that my account bought it?

I have recently bought my Mac mini ( July 12) and have already requested my free update code for mountain lion, got a reference nr, but I still haven't received a code via email to update? Its been 12 days. Any advice?

I am still in the return window but i really do not want to return my mac as i know it has the ability to do what i want, my problem is just finding the software that will work as i know there has been a lot of complications with OS X Mountain Lion with softwares that caim to be compatible but then later turn out not to be.
I have been a windows user for years and this is really my first mac but apart from the hole software issue i find the mac 10x better than any windows computer i have ever used. For example i bought a HP laptop 4 weeks ago and has nothing but problems. At first the fans stopped working and making weird noises and then it began switching off when ever it felt like it and freezing like mad when i was trying to access the smallest program. I have found that now a days you dont get what you pay for with Windows especially since Windows 8 was released. Also Laptops such as HP now are just crammed with cheap parts, they dont take pride in their systems like they once used to unlike Apple. I know i will get more than a year or 2 out my mac (hopefully a lot more) but with windows systems it just seems to break all the time costing more money on extending warrantys. Also i like mac because i dont need to send it away if i ever get a problem, i can just take it into the apple shop half a mile down the road and they will fix it in store. Where as with windows i am waiting 2 weeks+ to just hear back from them.

I Purchased Mountain Lion via app store - now I cannot download it.

I purchased a license for OS X Mountain Lion via the App Store and now I cannot download it.
Clicking on the download button did nothing.
Check for unfinished downloads says all downloads are complete.
There is no installer file named "Install Mac OS X Mountain Lion.app" anywhere on my system.
Now "OS X Mountain Lion" is listed under a seperate catagory "Other Purchases" and the button
is solid grey with no "DOWNLOAD" text.
I paid for a copy of OS X Mountain Lion but I recieved nothing in exchange for my payment.

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.
Then you will need to contact Mac App Store (MAS) support and clear up the issue before you will be able to download the Mt Lion installer.

Is it possible to upgrade a computer that qualifies for Mavericks to Mountain Lion via a content code purchase from the Mac App Store?

I inherited a situation where a previous consultant purchased a Mountain Lion installer code from the Apple Store but Mountain Lion was never installed. I obtained a new installer code from Apple based on the valid purchase of the Mountain Lion software last month.
The Mountain Lion installer appears under Purchases in the Mac App Store, but nothing happens when I try to download it. When I try to redeem the purchase by inserting the content code I get a message indicating that the content code has already been redeemed.
I don't mind spending $20 to purchase a fresh content/installer code, but I would like some assurance that the Mountain Lion software can be installed on a computer that qualifies for Mavericks. Not wanting to upgrade to Mavericks is not my idea but is that of my client.
Or to put it another way, does Apple prohibit such an install unless the computer in question does not qualify for a Mavericks upgrade?

It is your decision which OS you want to upgrade to - Apple does not place such restrictions (unless the machine specs do not meet the OS's specs or vice versa). So, if yours does meet Mavericks specs, it can run any OS newer than what it came with.
So, which OS does the machine have now?
I inherited a situation where a previous consultant purchased a Mountain Lion installer code from the Apple Store but Mountain Lion was never installed. I obtained a new installer code from Apple based on the valid purchase of the Mountain Lion software last month.
Was this purchase done on this same Mac? If so and someone else purchased the OS, then the likely answer is: any OS or app obtained at the app store is not transferable - its' license is tied to the original purchaser's Apple ID forever. So, it may have been a valid purchase, but it is tied to the purchaser, not you.
In order to get past that, you will need to wipe the drive booting from either the original install disk (which OS did the Mac come with?) or using recovery if it was Lion. After wiping the drive, reinstall the original system, and then you can purchase and download any OS version you'd like using your own Apple ID.
Let me know if I misunderstood the situation.
