Apple doesn’t want its customers to repair their own devices. Its phones and laptops require specialty tools to open and repair and sometimes pushes software updates that disable features on phones repaired with aftermarket parts. So it’s probably not going to like that someone has uploaded what appear to be 11 of its internal repair videos to YouTube.

Apple did not immediately respond to a request for comment, but two sources in the repair community familiar with Apple’s repair policies told Motherboard these are indeed genuine Apple how-to videos. The videos themselves have an Apple copyright on them, the host references internal Apple documentation and diagnostic tests, and, most importantly, the videos use proprietary Apple disassembly and repair tools that Motherboard has previously confirmed are manufactured by and are exclusive to Apple.
