- During my time at Apple I never saw any of the macOS source code, at all, even for userspace components. I had not even heard of things like SPTM.
- I have not worked there since June 2025
I don't believe that there's any risk due to my former Apple employment. As another example, WINE does not ban all former Microsoft employees, they just ban anyone who has ever looked at the Windows source code. If I felt there was even a chance that my employment at Apple may have exposed me to relevant internal secrets, I would refrain from contributing to community projects.
It's an interesting example given that Wine considers deriving code from traces of original components (like hypervisor traces) tainted and also bans LLM contributions for legal considerations: https://gitlab.winehq.org/wine/wine/-/wikis/Clean-Room-Guide...
