I just got a new Macbook pro with Mavericks already installed, downloaded monkey, downloaded line 6 hd500 edit, neither of them recognise the hd500 and line 6 monkey drivers are not updating, I've downloaded and updated new mavericks usb drivers about 9 times and still when i open monkey it says i need to update USB drivers. i cannot update the device firmware because it says there is no device.
please help i need to update my patches for shows in a week.
