I am sitting in front of an 15" TFT iMac (G4) which has a combo drive built in.
The system profiler calls it: “HL-DT-ST RW/DVD GCC-4120B”
Of course that device is from LG. Now I ask myself if this thing is a GSA 4120B and could burn DVDs and just has a different firmware which crippels it to a combo drive???
Apple is known for ordering special versions from its retailers (like other firmware etc.). Anybody got a clue?
