Superdrive will not burn on mountain lion

After installing mountain lion on iMac, superdrive will not burn or recognize cd/dvd. Have tried several different brands and burning software with same results.

If you have a CD or DVD, insert the disk and see what happens. If the drive kicks back the disk or gives you some kind of error message, then it's most likely a hardware issue, and might require a repair. However, if the drive seems to work fine mechanically, then it's a software issue.

  • HT5022 Airport Utility 5.6 will not install under Mountain Lion

    I have older Base Station Extreme and Airport Express models that need to be looked after; however, the fix to install Airport Utility 5.6 under Lion will not work under Mountain Lion. The installer complains that "the version of Mac OS X on this volume is not supported". So...suggestions?

    That is correct. AirPort Utility 5.6 for OS X Lion will NOT install under OS X Mountain Lion. If you had it already installed, and then upgraded, it would have worked just fine.
    One option, is to use Pacifist to extract the utility directly from the .dmg file.

  • HT5022 What works with Mountain Lion?  AirPort Utility 5.6 will not install on Mountain Lion.

    What gives?  The AirPort Utility 5.6 wil not load on a computer running Mountain Lion.  Attempted both on an iMac and Macbook.

    That is correct, the 5.6 version of the AirPort Utility will not install under Mountain Lion ... but it will run on it once installed. One option is to use a utility, like Pacifist, to extract and "install" the utility into the Utilities folder.

    Thanks Doug, I did not know that. 
    Confrontation was not the intent.  Was merely trying to inform the posters that they may get better responses if they posted in the correct forum.

  • IPhoto and iMovie will not open with Mountain Lion upgrade.

    Since upgrading to Mountain Lion OS 10.8, my iPhoto and iMovie will not open. I am using a newly purchased MB Air. I re-installed iPhoto from the App Store after trashing my previously installed iPhoto application. IPhoto Library Manager was downloaded as recommended on Apple Support but also will not open. I also tried to trach the iPhoto plist as recommended by a community member.  Each application (iPhoto and iMovie) bounces above the dock and message received that application unexpectedly closed. Thank you for any recommendations.

  • External USB drives will not mount under Mountain Lion

    Since upgrading to Mountain Lion, two external USB2 drives that I have will not mount and cannot be viewed in the Finder.  The same occurs on a 2012 MacBook Air, a 2009 iMac 27 and a 2010 MacMini, all running OS X Mountain Lion version 10.8.2.
    Both drives are Samsung Story external USB drives (one is 1.5 GB and the other is 2 GB) and both have been formatted using Mac Disk Utility with a single Mac OS Extended (Journaled) partition, one using Snow Leopard and the other with Lion.
    Both still mount correctly on a friends MacBook Pro that is still running Snow Leopard, and I had no problem with the same drives under Lion.  Interestingly both can also be connected to Time Capsule USB port and show up correctly.
    Both drives mount correctly under Windows 7 on BootCamp partitions that I have on both the 2012 MacBook Air, a 2009 iMac 27. These BootCamp partitions have Paragon HFS+ installed so I can read Mac formated drives.
    Both drives show up in Disk Utility, but when attempt to mount the drives I get the message "The disk could not be mounted.  Try running First Aid on the disk and retry mounting." I can run Repair in First Aid on the disk and get the message that the volume appears OK, but again have the same problem when I attempt to mount the disk.
    I have also tried using Disk Utility 3,2, but still cannot mount the drives, though the program indicates there is no problem with the drives.
    I have other portable USB including a Samsung portable USB2 drive, and two external USB3 drives, and I don't have problems with them.
    There is clearly a problem with Mountain Lion with accessing (mounting) these Samsung Story USB drives, and the problem appears to be with Mountain Lion itself as the problem did not occur on the same Macs with Lion and does not occur with Bootcamp partitions on the machines.
    I have a lot of time searching forums, but I have not found anyone with an identical problem.
    I sure hope someone can help or that Apple come up with a fix for this issue which has only developed since the update to Mountain Lion.

  • IPhoto will not update after Mountain Lion install

    Installed Mountain Lion last week. Running software update results show an update available for iPhoto but iPhoto will not update to the latest version using the APP store update interface.

    Have you bought it in App Store or in a disc? If you bought it in a disc, download iPhoto 9.3 and iPhoto 9.3.2. If it has been bought in App Store, delete and install iPhoto

  • Epson ICC profiles will not install in Mountain Lion

    I have an Epson R1900 printer which requiress icc profiles. The generally agreed route has been to use those from Epson of America and these work fine on my PC. On the Mac however only the matte set will install. The glossy profiles bring up an error stating that I do not have enough permissions to complete the install. I believe this was also a known issue in Lion and I have found one suggested solution which was to adjust permissions in Colorsync and Profile folders in the Library.
    However, in Mountain Lion this did not work for me. Does anyone else have success in installing these profiles?
    Previous discussion here https://discussions.apple.com/thread/3319527?start=0&tstart=0

    I just used the Pacifist tool to peer into the Oct 4, Epson Printer Drivers v2.12 for OS X package. In particular, for the R1900, both sets of the ICC profiles are installed into the following paths. Supporting code for this printer is installed under the InkjetPrinter2 hierarchy.
    /Library/Printers/EPSON/InkjetPrinter2/ICCProfiles/SPR1900_A.profiles/Contents/R esources
    /Library/Printers/EPSON/InkjetPrinter2/ICCProfiles/SPR1900_W.profiles/Contents/R esources
    The AutoSetupTool is installed in:
    /Library/Printers/EPSON/InkjetPrinter2/AutoSetupTool/EPIJAutoSetupTool2.app
    Everything in the above paths is owned by root with group admin. The individual R1900 .icc files are read/write by root, read-only by everyone else. There are two categories of .icc files for the R1900 as shown below:
    Stylus Pro R1900 A Profiles
    Stylus Pro R1900 W Profiles

  • Sony EX1 .mp4 files will not play in Mountain Lion

    I have .mp4 files from a Sony Ex1 camera.  They are in the correct file structure in the BPAV folder.  They will open and play in Quicktime 7 but not Quicktime 10.2. (Black screen, no audio.)  They will not preview (black screen, no audio)   They will play in the Sony viewer.  Of course they will not import into a NLE.
    This is what Quicktime 10.2 inspector says:
    MPEG-4, 1,920 x 1,080
    Linear PCM, 16 bit big-endian signed integer, 2 channels, 48000 Hz
    All the files worked fine till I "upgraded" to Mountain Lion
    I can play .mp4 files I compressed myself.

    VLC will play the AAC audio files. It reports the following as their codec:  MPEG AAC Audio (mp4a) 48 kHz
    Incidentally, I get the same results (no audio) when attempting to play the QuickTime audio files on a MacBook Air that is also running 10.8 Mountain Lion. When I boot into 10.6 Snow Leopard on the same computer, the files do play properly in QuickTime Player.

  • Bridge will not start in Mountain Lion

    I originally had this problem with Lion but a reinstall of the system cleared things up. Now since installing Mountain Lion Bridge bounces once in the dock and thats it. There is not even a recognition there was a crash.

    So, I've been having a problem very like this and perhaps can offer a bit of insight. At least I found what was going south for me.
    My problem looked like this: Start Bridge and there'd be a flicker of a window followed by a dialog with "Bridge is unable to perform this action" (or words to that effect) followed by a crash.
    After reading this thread I tried the previously-unknown-to-me OPTION start. That didn't fix the problem but it did eliminate the crash!
    Interesting.
    Now this problem began for me when I upgraded to Mountain Lion a while ago. After that my system began to become increasingly unstable. When I bought a large SSD to be my system volume I thought it would be a good time to do a clean install of everything.
    That went well, actually. Bridge worked in the new account I created! Wonderful! But I needed to use Migration Assistant to bring over my old account which had existed, more or less unchanged, since OS X 10.0! But then I began to have the same kind of instability I had seen before: Finder crashing, Path Finder crashing, and Bridge not working although the other Adobe products including Lightroom 4 worked just fine.
    So I poked around and here's what I found: different Groups. In older versions of OS X the user account was a part of group Wheel. This time it was a part of group Staff. Different group numbers. Hmmm. So I started at the top level directory of Users where all the accounts live and I changed the Group, recursively, to Staff.
    And then Bridge worked fine and there were no more Finder crashes, at least until I shut down for the night.
    So you might want to check both ownership, group and permissions in your accounts and see if this is a part of the probem.
    Why Mountain Lion (or maybe even Lion) changed the assigned Group for new accounts I cannot explain although, as I was walking the critters tonight and gazing up at the just-past-full moon, I wondered if it isn't because OS X Server can be installed as a layer over ML and this is a part of that compatibility.
    Now I do think that by changing the whole tree heirarchy I may have changed invisible files that shouldn't have been modified. But for right now I'll live with that and see what happens.
    Now I just have to try to get Microsoft Office 2011 to install...argh!

  • Logic Pro 9 will not start in Mountain Lion

    I have gotten so much great info here, that I thought this would be the best place to ask my question. I am using a Mac Pro 3, 1 (early 2008). I bought the machine running Leopard, upgraded to Snow Leopard, lion, and Mountain lion with no problems. I have a valid license for logic studio eight and nine. Logic ran without problems… Until I upgraded to Mavericks. After upgrading, my computer started acting terribly. It was much slower, and I would get these terrible freezes where the screen would go kind of crazy flashing colors and stop working completely.
    After thinking it was my graphics card, and not wanting to spend $1 million on a new video card, I decided to try downgrading back to Mountain lion.
    First, I cleaned off the system drive, and installed mountain lion fresh from a USB drive. The crashing went away and the computer ran much faster and smoother.
    However, after reinstalling logic, I am no longer able to start it. As soon as I click on the icon either through Finder or a dock menu, it crashes almost immediately. It has never gotten to or through the part where it scans the plug-ins or anything. I tried to understand the report it generates, and understand the things that it is trying to tell me, but cannot make any sense out of what it is actually saying happened. I have updated the app as well. I am currently at 9.1.8.
    I don't know why this is happening, and don't know what the best next step should be. I already have everything moved out of the way if I need to do another fresh install. I was thinking to try a fresh install on a clean drive of Mavericks, and see if anything changes. Also, when I would try to change logic to start in 64-bit mode, there would be no option in the "get info" window to select or deselect 32-bit mode. It simply wasn't there.
    I can post specs/logs/error reports of course, but don't even know where to start. Does anybody have any experience with this? Does anybody have a suggestion for where to start? Do I need to get Logic X? (Logic was running fine in Mountain Lion before) I have scoured the Internet trying to find someone with similar issues, but haven't found anything that works. All I have really tried is reinstalling both the OS and the app. Everything else works great in Mountain lion. I still have my Snow Leopard disks if you think going all the way back there would be the best option. My OS is running in 64-bit mode, but when logic does try to start, it says 32-bit mode in the little start up window.
    I'm totally comfortable with Terminal, Console, etc, so can provide any info if anybody thinks they may be able to direct me towards a solution.
    Thanks for reading and thanks for any help or advice.

    Must be my chipset then, although another Mainstage board told me otherwise. (that it was the OS)
    When I upgraded my Duo2Core MBPro to Mavericks, I too lost Logic 9.
    I'm pretty much done with Logic 9, and pretty happy about the new Logic X, and happy that it works on ALL of my machines.

  • How do I find out which programs of mine will not work with Mountain Lion?

    I recently upgraded to Lion and found that all of my Power PC based applications wouldn't work (much to my surprise, as no one at Apple told me this when I inquired about the upgrade, nor is it listed in the App Store). Had to get a whole new Microsoft Word suite - after the fact.
    Now, I just got an email from Intuit saying that if I upgrade to Mountain Lion I will probably have to upgrade to the latest and greatest version of Quickbooks (unless I create a partition, which is waaay too complicated for me). How do I find out what ELSE won't work if I upgrade to Mountain Lion?
    Mac OS X (10.5.8)

    Here's a compatibility guide by a 3rd party.  I can't attest to the accuracy.

    I can burn CDs,play CDs and watch DVDs. I can not burn DVDs. I have iLife but I cannot run iDVD because it is not compatible with of my version of OS. Why I don't know. Why should I have to buy every upgrade that come out? I can live with that, sort of, but why can't I burn a data DVD? I looked for a new driver but there does not seem to be one for Leopard. will I have to buy iLife 09 to bun a DVD?
