I tested Epubor Ultimate to remove DRM on my Apple Silicon M4
I tested Epubor Ultimate to remove DRM from my own Kindle ebooks on Mac (Apple Silicon). The process required disabling System Integrity Protection (SIP) and using an older version of Kindle for Mac (7.53), which isn't trivial for a non-technical user, but their support/tutorial walks through it well. After following it correctly, the program recognized and processed my protected books normally. The trial version limits export to one page per book, so I haven't been able to validate the final result yet, but recognition and processing worked as expected. (Note: I received a free 7-day license in exchange for this review.)
