Hi Shaley.
I know your trick. It didn’t help. The error was the same.
Reiner.
I downloaded your “original” file. It didn’t open either. OS suggested to move it to the Trash. So I guess this was an improvement at some level, because the OS was thinking of it for awhile.
Next I did with the good old “xattr -cr” -operation for the app, and that helped. Now it opens.
Thanks.
