I have a older Mac Laptop that say's OS 10.5 cannot be installed although it has OS 10.6.8 installed on it now! I think it maybe because the discs I am using came from my iMac rather than a laptop. I need to get back to an earlier version like OS 10.5 or earlier to get some specialized programs to work. The programs won't work on OS 10.6.8.
How do I get back to an earlier OS? Can I download 10.5, or do I have to buy the discs from Apple... as usual?
