Are permissions specific to hardware or software? I ask this because I was wondering if I plugged my mac HD into my pc could I access the mac files even though they have "everybody" set to "no access"? I basically changed the permissions on my mac for eveyone to no access and now the machine wont boot. It won't even let me on safe mode.

 

I now have the original cd and have tried booting with 'c' and also with 'options' but nothing is happening Please help

MacBook, Mac OS X (10.6.8)

    Windows can not Read Mac formatted drives unless you install a special preogram that allow it to.

     

    If you set permissions on any file, set of files, folder or set of folders (or to the ROOT of the drive) you have screwed the Pooch and restricted access to No One even the system.

     

    Right the system won't boot because you have basically LOCK the drive for everyone.

     

    At the chime Hold Down the Option key until you see the Boot menu screen.

    Then you DVD drive is Non functional.

    You can buy any external DVD drive that connect to a USB port and it will work with your Mac and allow you to boot the install disc.

    Or if you have another Mac you could make a USB thumb drive if the installer. Can't do it on a PC.

    Doesn't matter if you used the drive Before.

    But if you have tried with an external DVD drive and it still won't show that external with the Snow Leopard install disc in the drive then I'm at a loss.

    You have to extract, Burn, that DMG down to a DVD disc and you should use a Dual Layer disc as the total files are over the standard 4GB limit of the single layer DVD disc.

    You have to Burn the DMG down to the DVD, Not copy it. Yes Extract it to individual files.

     

    That is why it isn't showing up. A DMG file does not have the proper BOOT files in the right place on the DVD. The system can't see the files needed to boot the system.

    No. You need a system, an OS, to Start the computer. Disk Utility is a Disk Management program Not an Operating system.

    I have no idea. Never ran Linux on a Mac, run it on PC. But I doubt anything you try will work. Even when and if you get the system started from that installer DVD you are trying to make.

     

    Setting the permissions on the Drive for Everyone to No Access basically FUBARs the system to the point about the only thing to do is Wipe the drive and reinstall the OS or Restore from a Time Machine Backup. I guess you don't have one of those either.
