And then there were the last minute RFI issues. Originally all was supposed to be well, but the far-field tests indicated that the case seams leaked a bit more than was allowed -I remember the term "slot antenna" being used.
The solution was to spray a coballoy (paint) coating inside the case -some were actually done using an arc-spray (metalizing) process. Both added some thickness and that caused interference at the seam, which caused difficulty on assembly. The solution was to put each Mac face down and push the back onto the bezel with a large arbor press -a stunningly manual step in an otherwise automated factory.
