Information you can find in System Profiler.
As Apple hardware improves, the latest and greatest versions of different devices are installed in Macintosh models. As a result, some older optical drives may not be able to write to all the formats that current optical drives can write to.
How can you tell which formats your optical drive can write to? Ask System Profiler. Here’s how:
Choose Apple > About This Mac.
In the About This Mac window that appears, click the Move Info button.- In the left column, under Hardware, click Disc Burning.
- Consult the lines labeled CD-Write and DVD-Write to see which formats your optical drive supports.
- When you’re finished, choose System Profiler > Quit System Profiler to Quit.
