CD doesn't show up. Can't eject!
I inserted a CD with photos on it this morning and it doesn't show up. I can't eject with the eject button or with the eject command in iTunes. Have also tried restarting with option key, still doesn't show up. I don't have a pin hole next to my CD/DVD drive, just a small oval hole. Really important CD. I just used the CD drive yesterday to download some music and had no problems with it. Any help would be appreciated.
MacBook Pro, macOS Sierra (10.12.6)
