Not sure about a Mac Pro but on an iMac with an internal optical drive (superdrive - Optiarc DVD RW etc) you get a screen that indicates that you can Rip and Burn CDs. I attach a screen shot of what I get when a normal CD is inserted. If I put a recordable disc in the drive, nothing appears under Drives and Devices
Although ripping is now generally stable on Macs with internal drives and perhaps external drives, burning has never been available on Mac using MC and still is not. You have to burn separately using the Mac built in programs, iTunes or an external program.
