Hello all, I owned this iMac G4 for two years now, and when I bought it, it had a Kensington lock, whose wire was cut, that I couldn't remove. I tried recently again since I wanted to perform a full clean-up of my computer, but I still couldn't do it. I tried using the cardboard technique, tried to use a flat screwdriver, nothing worked, even trying to remove the thing from the inside of the iMac failed. I even tried a Kensington key I found from someone, but it wouldn't fit, I assume because they're all slightly different. I could try and cut the whole thing somehow, but I'm really afraid to damage my computer. Any tips? Thanks.
