References and Sources

Lirum Device Info's built-in device database is compiled from Apple's own published specifications and from open, community-maintained references. Individual factual values (clock speeds, resolutions, capacities, model identifiers) are not copyrightable, and we transcribe and re-enter them into our own database schema rather than copying any source's text, tables, or compilation.

The links below are provided as reference and further reading for visitors. Where a source has gone offline or been altered, we link to an archived copy on the Internet Archive's Wayback Machine and note its status.
