I found a way to fix it for me.
Open terminal and issue:
xattr -cr /path/to/application.app
Then it should run fine. Hope it helps.
Unfortunately this did not work for me either - got a "no such file" message in terminal. Any idea why/what to do?
> /path/to/application.app
this is where you copy of WOH is.
I tried the above terminal command and it fixes it.
Got it - thank you so much!!
This seemed to work for me.
