Fraktur is not included in the standard ABBYY supported languages and requires a specialist licence. I had seen that Tesseract supported Fraktur however as yet we haven’t had a chance to test it. We will be adding support for other languages in future updates and I have noted your request for Fraktur.
I assume you have a M1 Mac. In DEVONthink 3 the ABBYY OCR is working in Rosetta2.
