Just installed Panasonic's UJ-235A into my mid 2010 27" iMac & it accepted a disc but that's all it's doing. Clicking 'About this Mac' then 'More Info' & the drive is detected - OS X recognises it & lists all its capabilities but can't see it in Finder, VLC or any other program. The keyboard eject button doesn't work. Tried getting the disc out using the 'drutil eject' command. The drive makes a noise like it's going to eject, but doesn't.
Have you, or anyone else, installed this drive & had any luck using it.
Any suggestions would appreciated.
