I am currently having problems opening Anki on my macbook pro. I try to open the anki application and it will continue to “bounce” up and down on the dock but never opens. I have deleted and reinstalled, reinstalled older versions as well as the alternate version and also checked for malware. I had got in contact with apple support and we have come to conclusion that is user specific. We created a new admin user and Anki opened just fine. Apple had sent me to this discussion page to get help in regard to pulling folders that may cause this issue.
