Can't open DMG files...should have never upgraded my OS to mountain lion

Upgraded to OSX 10.8.2 and now I can't run any downloaded dmg files. Says "the Following disk images couldn't be opened". and then say's there "isn't enough disk space" I'm pretty sure it has something to do with apps that are not approved by the app store. How can I turn it off?
I posted this question before and thought the problem has been solved nbut i'm still having this problem.

How much disk space do you have? When you "Get Info" on a .dmg file, is it set to open with "DiskImageMounter.app"? Should have nothing to do with your Security settings just to mount a disk image.

  • Can't open DMG-files

    I can't open DMG-files anymore because OS X associates dmg-files with another program. Usually when I opend .dmg files a "virtual disk" opened, now another program starts.
    I tried the Open with (Openen met in Dutch) function, but I don't know which program I have to choose. When I have this problem on a Windows PC I just select explorer.exe. Which file do I have to choose on my Mac? Or is there another way to solve this?

    Hi mrtn87,
    welcome to Discussions!
    /System/Library/CoreServices/BOMArchiveHelper.app opens .zip files,
    and
    /System/Library/CoreServices/DiskImageMounter.app opens the .dmg files.
    If you have OnyX, you can try running the "Reset LaunchServices Database" and "Reset links between documents and applications" tasks, see if the problem disappears.
    Here is a Terminal command you can try if you don't have OnyX (or one of the usual utilities):
    /System/Library/Frameworks/ApplicationServices.framework/\
    Frameworks/LaunchServices.framework/Support/lsregister \
    -kill -r -domain local -domain system -domain user
    Let us know.

  • Help! Can't open .dmg files suddenly, and can't find stuffit expander application!

    My iMac is currently running on Mac os x 10.5.8, **out of nowhere my computer can't open dmg files. I can't seem to find the stuffit expander application anywhere in my hard drive either, which usually opens these files. Is there another application that can open dmg files? Help Please! I need to open multiple dmg files tonight and can't figure out a way around this. Downloading/running a new stuffit expander application also happens to be a .dmg file. If anyone can help me I'd appreciate it so much!

    Do you mean DiskImageMounter was chosen or not?
    No change on that .dmg or on on others?
    If you want to apply DiskImageMounter to all you have to choose "Change All".
    EDIT: Also, Repair Permissions from /Applications/Utilities/ Disk Utility.
    Also, George Orville has some interesting advice in this thread
    Note this advice is for 10.3 but much of it will apply here.

  • HT1338 can't open dmg files on my new iMac

    I have a brand new iMac updated OS X and I can't open dmg files. It appears that I don't have DiskImageMounter. What do I need to do?

    The path for DiskImageMounter is Mac HD/System/Library/CoreServices.
    EDIT: Get Info on the .dmg and make Open With= DiskImageMounter, then clcik on Change All.

    How are you trying to open it?  What happens when you double-click it in the Finder? In the Finder Preferences do you have Show these items on the desktop: "CDs, DVDs, and iPods" selected?

  • I can't open dmg files anymore

    I JUST got this problem. I have been using my mac for a couple of years now. My Mac is a Macbook Pro, Version 10.7.2 (Lion)
    Recently, I have been unable to open Dmg files, whenever I double click it, I get a message saying:

    I never had this problem before, so why am I getting it now? How do I fix this?

  • My Safari can´t open .dmg files after downloading

    I updated to Mac OS X 4.9. But since this update, Safari cannot open .dmg files after downloading! On 10.4.8 it was not a problem. What can I do?
    eMac G4 PPC   Mac OS X (10.4.9)  

    Darn...I thought that would do the trick.
    Given the other problems you mention, more and more, it seems a reinstall of the OS, using Archive and Install is going to be necessary. Have you ever done an Archive & Install of the OS? Important you carefully read the description of the process. If you are uncertain, I find the Take Control Upgrading to Tiger E-zine to be a very helpful guide.
    Once you reinstall the OS, then you can upgrade to 10.4.8 using the combo update, repairing permissions via Disk Utility in your Utilities folder when complete.
    One question: Not sure why you have run into all these problems on the 10.4.9 upgrade. It worked without problem for me. Anything unusual happen during the install?

  • Can't open old files in CS5 since upgrading to OS X 10.9 Mavericks

    Since I upgraded to OS X, I can open all my CS5 programs and create new files. However, I can't open files I created (even a week ago on CS5) since I upgraded to Mavricks. I googled it and I tried updating my Adobe drive and I updated Java, but I still can't open any file I created before downloading mavericks. In Indesign, I get an error message "Adobe InDesign may not support the file format, a plug-in that supports the file format may be missing or the file may be opened by another application" and In Illustrator I just get the spinning wheel of death...
    Any ideas or suggestions?
    Thanks!

    Talk to Apple support about updating your permissions - that may be it.

  • Can't open .dmg files, says its "not recognized"

    I have recently tried to mount a .dmg file but a dialogue box will always open, saying that the disk was "not recognized".
    I've already checked "From anywhere" under "System Preferences/Security and Privacy/Allow applications downloaded from", so there should be no problem with downloading a .dmg file off the internet, right?
    The .dmg is an Adobe Extensions Manager CS4. I'm using a Macbook Pro with OS X 10.8, and yes I already know that particular extension manager is not for this operating system, but this has already happened with a 10.8 version as well.

    If you right click on the dmg can you open it? 
    Use Software Update or the OS 10.8.3 combo update to update your OS.  Also, update everything SU has to offer for your computer.  When done, repair permissions and restart your computer.

  • Can't open .dmg files in Mavericks

    Upgraded to Mavericks but can't open any .dmg files. Get this message:
    Your security preferences allow installation of only apps from the Mac App Store and identified developers
    This is no good. HOw do I change security prefernces to bypass this to update software that will work with Mavericks? Right now Toast 11 crashes when I upgraded

    Go to: Apple System Preferences > Security & Privacy > General tab > click the Lock > enter your password > select Anywhere.
    If you are the only user and are very careful, then it might be OK to leave the preference set to Anywhere. If you are hap-hazard about downloading stuff or other people use the iMac, then you would be wise to set it back once you have what you want.

  • Can't open .dmg files on Mavericks.

    Hello! I can't seem to open any .dmg files. Tried with DiskMounter and disk utility but still can't install any new applications.
    Anyone having the same issue with Mavericks? I upgraded 3 days ago and I don't want to regret it.
    I thought maybe some kind of OS installation 'repair' would fix the issue but I'm not sure if it's even possible.
    All tips welcome.
    Thank you!

  • Can't open DMG files on 10.5.8

    Hi,
    I just updated, and to my surprise I can't open any of my DMG files, not even the ones that I download from places like macupdate.com, can somebody help me? Thanks.

    HI,
    Try repairing disk permissions.
    Quit any open applications/programs. Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.
    This process can take up to 10 minutes.

    Why would you be surprised?  You were syncing your Notes with iCloud or a Mail Account.  Synchronization means when you make a change on one device, it affects all other devices that are synched for the same purpose.  Like when you delete an email (usually) it also disappears from your other devices as well.
