You can turn off those messages by going to the CDs and DVDs panel in System Preferences and changing what you want to do when inserting a blank disc. Do nothing is my choice.
Yeah. I experimented with that earlier and it didn’t work and now it does for some reason.
I now have it set to boot Toast 6 on insert of a blank DVD/CD and it all seems fine. Indeed a DVD is burning as I write and I now have Toast 6.1.1 courtesy of a thread on this board.
So in answer to the OP, Titanium 6
does indeed work with Intel Macs OS 10.5.8. I expect delivery of my free copy of Snow Leopard next week.
