    I'm new here (obv.) and i asked a friend where i should best ask mac related questions so please bare with me if i'm abit clueless.

    Okay, after around 7 months (got my MacBook Pro in September last year) i started to not be able to install programs downloaded off the internet.

    It would download and then ask me if i want to continue once it had finished, i'd say 'yes' and then the program would try and 'mount' and then it'd say, 'mounting failed' or 'disk image failed' (i can't remember which tbh). Anyway, the point is they wouldn't install. Nevertheless whenever i'd try and load the said program anyway by double clicking it from the desktop it'd load and then say 'broken pipe'. :S

    So, yeh, anyone know the problem/a way to fix it? xx

    Hmm, unable to mount disc images.

    I would suggest using the disc utility to create a .dmg file, use these instructions to create one (Don't choose to encrypt though, it's not necessary). Once you have created the disc image, see if it will mount.

    If it does not mount, use the Disk Utility first aid to repair your permissions, and verify your disc. If you get no errors after verifying the disc, try mounting the disc image again, if the issue persists then come back and we'll try something else.

    ok, i just tried the first bit. I opened Disk Utility and tried opening a New file like the guide instructed, it then immediatly stated 'broken pipe'. I have no idea what has happened :S.

    Okay, try verifying the disc and running the repair permissions (Run it again if you see anything like "We are using special permissions/permissions differ/permissions changed"). Then tell me what it says.

    Edit: Also, what version of Mac OS X are you running? You can find that information by clicking on the Blue Apple > About this mac.

    Okay, when i click Verify Disk and Repair Disk, they both state that it's passed verification...

    Verifying volume “test2”
    Checking HFS Plus volume.
    Checking Extents Overflow file.
    Checking Catalog file.
    Checking Catalog hierarchy.
    Checking volume bitmap.
    Checking volume information.
    The volume test2 appears to be OK.

    1 HFS volume checked
    Volume passed verification

    Verify and Repair disk “test2”
    Checking HFS Plus volume.
    Checking Extents Overflow file.
    Checking Catalog file.
    Checking Catalog hierarchy.
    Checking volume bitmap.
    Checking volume information.
    The volume test2 appears to be OK.

    1 HFS volume checked
    No repairs were necessary

    However the two icons next to it, 'Verify Disk Permissions' and 'Repair Disk Permissions' are greyed out and unselectable. I have no idea if i'm doing the right thing here?

    Edit - Version 10.4.9

    Oh, I guess I didn't mention it. When you select a drive from the left hand column in Disk First aid, choose Macintosh HD

    You should see something like

    WDSYTS120; That's your HDD (Note: That's not the actual name just an example). Then below it and indented you should see Macintosh HD, select that and the repair permissions should be selectable.

    If you find nothing wrong with the permissions, do a safe boot by holding down the shift key while starting up the computer (Let go of it when you see the Grey Apple). And then download this and install it- or try to.

    Nah not yet, repair the permissions one more time and then restart the computer. After the restart try and mount a .dmg file, if you still get the same error then boot into safe mode.

    Also, be sure you can connect to the internet directly, as AirPort is disabled in safe mode.
