Hi, I would like to install Leopard 10.5 onto an external hard drive and use it as a boot disk (I will be using a MacBook Pro). I need it to run software that is only compatible with 10.5 or lower. However, the only 10.5 disks are the disks that came with some older Macs. Will those work (can I install the OS onto the external hard drive), or wil I need to buy 10.5 disks that can be used on any computer?
Thanks.
Thanks.
