I have a MAC now and something is up with the spacebar. It was kind of stiff on the right side, so I followed some instructions, took it off, and cleaned it. All the parts are there, nothing is broken.
I put the key back on and it seems tilted and stiffer than before. It's facing the right direction. Yes, all the hinges are okay and seem to have snapped into place. Yes, the tiny metal bar is tucked into the tiny metal thing it's supposed to be. Still my space bar is tilted.
The parts are there. I can't tell what I'm doing wrong.
