I have a mac with OS 10.3.7. I have bought a Liteon dvd burner from macmall.com. They said that it was mac compatible, but my mac and toast would not recognize it. I sent it back. Then I got a LaCie from newegg.com, not only did my mac/toast not recognize it, I could not even get the DVD door/tray to open. So, I'm sending it back today. What DVD burner can I buy will work with my mac, and toast will recognize. Give me a suggestion of brand and what to do to get the mac to read it. Thanks for you help.
