Kami will not work on my Mac


Kami works perfectly on my Samsung laptop but when I try to open PDF’s on my Mac, I can only see the notes and the PDF is blank. I have uninstalled and reinstalled, rebooted my computer, chose for Kami to be my default PDF viewer - and nothing has worked. I am running the same version of Chrome as my coworkers, and we have all the same settings checked. Can someone help us???
