    Well, i have a Macbook Pro 15" late 2011, and when it's cold it sometimes freezes (i'm not sure why, and i don't have apple service in my country).
    So, when i first start it up, it sometimes freezes (because it's cold)
    But when it warm, everything is ok, so i wanted to ask, if there is possobility to setup a delay (for about 30-40 sec) in startup, so it could get warm, before gpu is loaded.

    For example enter in single user mode for 30 seconds and then exit to normal mode, but without my help, some kind of script maybe?
    Please help. And sorry for my english, i'm not a native speaker.

    Maybe install refit and set to auto boot the Mac partition after X amount of time?

    Try this:

    sudo defaults write StartupDelay -integer 30
    That'll make it delay 30 seconds. I'm not sure if that'll work for you or not.

    This didn't work, the delay is after gpu kexts are loaded, so it freezes.

    Thank you for simple and working idea.
