The publication office of Mojtaba Khamenei switched their design computer from a Mac to a Windows machine in early June 2026, according to an OSINT investigation of PDF metadata. Despite the change, the Adobe InDesign version identifier embedded in their PDF files exactly matched that of Mohammad Bagher Ghalibaf's office. The identical tool signature, extracted from PDFs shared on their respective Telegram channels, was:

Adobe InDesign 21.0 (Macintosh) | Adobe PDF Library 18.0 | Adobe InDesign 21.0 (Macintosh) | Adobe PDF Library 18.0 | Adobe XMP Core 10.0-c000 25.G.ef72e4e, 2025/06/27-18:54:05 | 1.4 | ar-SA | Adobe InDesign 21.0 (Macintosh)

Despite the migration to Windows, the signature still references 'Macintosh,' suggesting the metadata was carried over from a template or the original creation environment. The digital fingerprint points to a shared or closely related production environment between the two offices.
