Uninstalling Sophos on a Mac

Zavatone

Hi.  I borrowed a Mac with 32 bit EFI to test SafeGuard on.  Just ran a decrypt drive last night since I have to return it but lo and behold, after I reboot it, there is the Sophos login screen (the mouse doesn't function BTW, how are you supposed to click the buttons?)

But anyway, I've read the MacSGNuserguide.pdf file, searched the forums for "uninstall mac" and there are no removal instructions for the software.  Since I need to return this Mac, where can I find out how to uninstall the package?

TIA, 

- Alex Zavatone

    Just to add some information:

    Concerning enc/dec speed: Encrypting a HD takes some time. It is mostly related to the fact that every single sector needs to be read/written. The acutal bottleneck in this case is not our software it's the HD itself. You'll see a significant performance boost when using SSD's. While I understand that it's annoying to "wait" for the initial encryption to complete you can still continue working with the machine and could do all the tests.

    Just to make it clear: We do not need a 64 Kernel, but require(d) a 64bit EFI firmware. The next release scheduled for beginning of 2011 will also support "old" EFI32 firmware environments.

    Concerning decryption/OS upgrades: Upgrading an OS is not a trivial task, pretty much everything changes, from the Kernel to the boot loader. So it's probably better to not support such scenario. Otherwise it could lead to complete data loss. I'm not aware of any Full Disk Encryption software (either on Mac or on Windows) that allows _encrypted_ OS upgrades. Updates are not a problem as those usually introduce only minor changes. Upgrades are in fact prevented by Apple as they seem to detect that they will not be able to access the HD without specific drivers...

    Regards,
