A collection of papers and presentation slides related to macOS, iOS, and (U)EFI Firmware.


This is my archive of papers related to macOS, iOS, and (U)EFI Firmware. It was previously hosted at my blog but moved here for easier management.

The content will be always available but if you really must mirror it please do it gently (contains more than 1gb of data).

If you find any missing paper please email me at papers @

Starting in 2019 the content is added to the end of each page and not anymore at each year (dropped organization by year). For a long time I wanted to have a changelog to see what new content has been added. This solution avoids a separate changelog, and at least for now I think it is a better solution. A new year field is added to keep track of each paper.
