I don't have a new iMac, just 2015 macbook pro the drive still works with that but I need to get old batteries removed or device recycled. I may get a mac mini or studio sometime later this year if I can afford that. Got a new microsoft surface ten device with usb-c dock, unfortunatley the mac superdrive doesn't work with that not sure why. May get new universal cd/dvd drive that works with windows. I can play dvds / blue ray disks on xbox also.
The old imac just has nice presence to sit on desk and play documentary dvds or music in background. Will try again to reset password today, may need to reset root administrator password instead of user and keychain password also is different than login password. Not sure if there is error that prevented that from working the first time. Now the device requires login password on startup, darn. Tried resetting O.S. but that didn't work over internet, don't know if O.S. Lion is even on Apple servers anymore. May still have physical disk of that or can see if I can get a new disk of that to reset device.
