I can only talk about my experiences with getting a code signing certificate and card reader for a Mac using Apple Silicon and macOS 26.3.It does not work ! Not all their software has been adapted for Apple Silicon. Certum Tools which is a java program won't work on apple silicon. The other applications are poorly translated from Polish into English and it's not possible to install a certificate from their website onto your local machine for reasons unknown. Support seems to be low quality and resorts to "reinstall" and don't understand the problems with CPU architecture. Had to return the lot and request a refund. Postage at my own expense.
