Apple EFI firmware passwords and the SCBO myth
These could be insiders working at Apple support centers or even Apple itself.It makes me somewhat happy in a weird way to think that, even in notoriously locked-down and secretive companies like Apple, there are individuals who don't believe in and subvert the company's attempts to have sole control of its products. We have these individuals to thank for schematics, parts, and a lot of other material that feeds the third-party repair industry.
