I downloaded version 7.5 and had to re-download which took some time. But it froze immediately upon launch, this is Mac OS version. So I had to force quit and re-start my macbook. Tried again, it froze again. I then tried 7.4 and it seemed to work but was especially laggy. But when I tried to send some tokens, it froze on the "confirming" window. I am at a loss on what to do from here.
