This question is for my Mac and OS X comrades:
When I upgraded from Tiger to Leopard, I had a bunch of device profiles left over from my use of PatchBurn in Panther and Tiger. When I look at these drives now under system info in Leopard, it says they are vendor supported.
My question is, should I leave the old device profiles there, or should I delete them? I know where they are and how to remove them, but I'm curious because the author of PatchBurn implied that they no longer had any purpose under Leopard, and that the OS ignored them. Yet, under Leopard, there are still three different types of drive support, Generic, Vendor, and Apple, so if Apple didn't intend for there to be vendor supported drives, why does it still seem to recognize the profiles? Did the author of PatchBurn really know what he was talking about, or did he just make up an excuse to explain his abandonment of the project?
The heart of my question is, do device profiles for DVD drives still have any purpose under Leopard or Snow Leopard? Does it matter whether a particular drive is supported generically or has a device profile and is recognized as vendor supported?
