I have some legacy 3d modeling/animation software called Bryce 3D, that I need to use ASAP to work on some old files. The problem is, Bryce won't run on Lion. But it will run on Snow Leopard.
I'm currently using a MacBook Pro running Lion 10.7.5.
I was told by the legacy software company (DAZ3d) to install Snow Leopard on an external hard drive (partitioned or not), then install their software on that hard drive as well, then boot my computer from the external hard drive and run Snow Leopard and their software.
This evening I hooked up a Seagate FreeAgent Go 80GB external USB hard drive to my MacBook Pro, inserted my Snow Leopard install disk and clicked on the installer. Immediately I received a message stating, "You can't use this version of the application install Mac OS X with this version of Mac OS X. You have to install Mac OS X 23.1.1."
I would imagine that would indicate some incompatibility between the OS on my internal drive (Lion), and the Snow Leopard install disk. Perhaps there is no backward compatibility or something similar. But I do not want to install it on my internal HD, but rather on the external USB drive mentioned above.
I tried clicking on "Other Installs" but when I did so it seemed the destination had already been selected -- my internal HD. The installer did not appear to "see" my external hard drive.
My next step was to boot directly from the Snow Leopard install DVD. I restarted the MacBook Pro and pressed the "C" key, but the MacBook Pro would not boot from the Snow Leopard install DVD. It did not reject or eject the install disk. It just took its time and eventually booted to the log-in window of my internal hard drive.
I checked out the external drive via disk utility and it's formatted Mac OS Extended (Journaled) and the partition map is GUID. The partition is 70 GB -- more than large enough to comfortably install Snow Leopard and run the software.
I'm not sure what the problem is. Seems like this should be a straightforward process. Suggestions?
