superdrive on older MBP
I just picked up a super drive from a second hand store. Looks to be in good shape.
However I’ve plugged it into both my older MBP, mid 2009 and 2012. I hear the drive mechanism chirp as soon as it’s plugged in. But both the MBP immediately say it’s not compatible. Trying to insert a disc it doesn’t respond either.
Is the drive just defective?
