    Hi Yakub,

     

    The device you're talking about as a Macbook Pro 3,1 I believe:

    I think those machines have Nvidia GPUs that may or may not be supported, so beware of that factor.

     

    In terms of just getting the USB to show up as bootable - you might need to do a PRAM reset or similar to get it to show up.

    Thanks for the reply Forest
    I've tried the pram reset. But still no.luck.
    Any other ideas on how I can make the usb discoverable?

  • Forrest Smith

    Nothing comes to mind - maybe try a different USB port or a different USB device? Sometimes USB 2.0 vs 3.0 hardware can impact older devices.

    You probably need the 64 bit version....the 32 won't boot uefi on that boot manager.

    Thanks for the replies guys.
    Ill give an older USB a try and let you know how I get on.

    Hi all
    So I.managed to get hold of an older usb2. And thankfully the macbook recognised it this time. Booted from the sub and everything worked fine just as it should.
    Went ahead and installed cloud ready. Now the problem is that when I start the MacBook I get the usual.start up with the chime and white screen. The then the screen goes black and nothing. It just stays black and doesn't boot.
    Not having much luck on this device. Any further suggestions would be really appreciated.
    Otherwise I think the MacBook may have to be put to rest.
    Many thanks in.advance

    Hi Yakub,

     

    A post-install reset of PRAM might be helpful.

     

    Also - did you machine shut down after the install completed? or did it reboot? The first is expected, while the second implies an error.

    Hi Forrest
    Thanks for all the help and advice.
    I reinstalled cloud ready and this time it seems to be working fine. Not sure what happened firs time round.
    The macbook doesn't seem to support right clicking using the big button under the touch pad.
    Is there any work around for this?

    None that I know of though two finger tap should work.
