    Hello everyone. I'm trying to install a very old version of Mac OSX, which requires the system date to be set around the year the OS was released. I set up a new VM, pre-OS install, and got to the UEFI shell. "help date" provides the syntax as you can see in the screenshot below. However, when attempting to set the date, the command seems to take, but does nothing.

    Of course, I've set time to "do not sync"

    Any suggestions? Thanks.

    Because that is not the solution - this is not a code-signing issue. The installer will not even begin to boot without the date being set on the machine first. The only way to set the date on the machine is through the UEFI, and that appears to not be working - probably a Parallels bug. Any ideas why the UEFI date is not taking?

    The easiest solution is to change date on Mac HOST at the installation stage.
    I.e. disconnect Mac from network, change date/time on host, start the VM, pass problem stage, suspend/stop the VM, enable network on host (change date back if not set automatically)

    The Mac is a server, running many VM's and hundreds of TB's of storage - I cannot take it offline (except for scheduled maintenance), and changing the date would have disastrous consequences, so unfortunately that's not an option. Sure wish the date command in the UEFI worked like it should...
