Well I purchased it but can’t install it. I have an older MAC running 10.3 software. Tech support said it has to be 10.4 or above to install. Their response was : Unfortunately, we can do nothing for you”. If I upgrage the OS, than my protools LE version 6.4 with digi01 will not be supported. Does anyone know the cheapest way I can get protools and ezdrummer to run on my MAC without downgrading to an MBOX? Newbee recording artist….
