OSX Boot problem.

countzero

Hi all.

We have an iMac.  It was encrypted with Safeguard but the software is still installed.

The only account with Admin' access was suddenly unable to login - we suspect a corrupted profile.

We tried to boot from the install disk but are unable to do so because of the Safeguard login at boot.

We un-encrypted the disk but still get the requirement to do a Safeguard login before the machine will boot and still cannot

boot from the Mac install disk.

We are unable to uninstall Safeguard from a normal user account as the system won't accept the Admin password!

Any suggestions?

We are now considering removing the HDD and erasing it however this will probably invalidate the Apple warranty on the machine.

    Hello Countzero,

    many thanks for your posting and welcome to the forum.

    If you want to boot from the Apple install disk you don't need to authenticate to the POA (SafeGuard login at boot).
    Simply press and hold the Option key (alt key ) and start up your iMac until you enter the Startup Manager, then insert the Apple install disk, wait a moment and choose it.

    You will find detailed information in Apple Article HT1310

    The machine will then boot from the install CD and you will be able to access the disk utility to erase the HDD.

    So no need to remove the HDD :)

    Regards,
    Tim

    Hi Tim,

    I too have a problem on startup with my Mac Pro OSX 10.6.8 Quad-Core Intel Xeon. Unfortunately, I cannot do anything other than login with NO effect. No mouse (wired in not bluetooth), cannot hold shift or option to give effect. I'm frozen out. I'm also locked out of the CD tray and cannot load my system disc. Any comments?

    Regards

    Rod

    Hello Macman,

    many thanks for your forum post.

    This sound really strange as the EFI boot menu (which has normally nothing to do with SDE4Mac) should always be accessible by holding down the option "alt" key when booting your computer.

    This issue would need further investigation. Please get in contact with Sophos Support.

    Regards,
    Tim

    If you have a corrupt mac install and you've decrypted the volume, call support and ask for the OS X SGN Purge Tool.  This tool will purge SGN from your system but ONLY if it's decrypted and shouldn't be used normally because it can be risky to use depending on what other security software was installed so it's not normally distributed to customers.
