A Mac will burn CDs, but DVDs are a different story. I am finding with El Capitan [Apple's old software] iDVD (v7.1.2 2010) will burn DVDs. I have found like this thread is saying that T14 crashes in may ways - software hangs after burn, Disk fails to burn, the Drive Reported and Error: Sense Key=medium Error etc., menu fails to burn (reported). Also, I have had success burning HD video and BD video disks (menus are not burning for me but the disk will launch in my player) and I have created a few coasters in the process. My success comes when nothing else is running while encoding (DVD/BD) and only if I create a BD image first - i.e. don't encode and burn in the first try. Search for this pdf on the web it may help you, it helped me - Your Easy Guide to Burning Blu-Ray Video Discs on Your Mac From OWC.pdf
For DVDs I really like "Wondershare Video Converter Ultimate." It is fast, reliable, and has many themes. Unfortunately it doesn't burn Blu Ray disks. Roxio is a little better at producing a HD DVD on a DL Disk, but Roxio takes forever to create the disk.
