Anki not opening after downloading 2.1.49 Mac

Hello,

I have had Anki on my Mac and decided to download the 2.1.49 version. I downloaded it, placed it into my applications folder and elected to replace the existing version. Now when I try to open the app it just bounces on my desk top for a while and then if I click on it it says “application not responding”. I tried restarting my computer and deleted/re-downloading the same 2.1.49 version and 2.1.48 version without success. I would appreciate any help.

Please start Anki via Terminal.app:

/Applications/Anki.app/Contents/MacOS/AnkiMac

Then please paste any text it outputs here

You could also try renaming your prefs21.db file to something else while Anki is closed: Managing Files - Anki Manual
