Can't erase CD-RW's since installing el capitan.
Since I installed el cap on my Macbook Pro several days ago I am not able to erase CD-RW's. That option is grayed out. I also tried to do this on my wife's Macbook Air with an external Super Drive with the same results. This is something I do every weekend and have for years. Any ideas?
