Hello,
I get the same error messages, and I am also on MacOs Mojave 10.14.6, Knime 4.0.0, and Tess4J Integration 1.3.3.v201907171304 .
It seems that this issue on MacOS dates from Feb 2014 as shown in this thread : Tesseract Node not working
I found that there is a general issue of Tess4J on MacOS : apparently MacOS lib is not in the package. see more here: https://stackoverflow.com/questions/21394537/tess4j-unsatisfied-link-error-on-mac-os-x
(i have not tested yet the solution posted on stackoverflow)
Thanks in advance
Cedric
