Epic Privacy Browser Forums

Hello, I have a MacAir and each time I try to open the dowloaded file I get the message; “epic_71.0.3578.981.dmg” is damaged and can’t be opened. You should move it to the Trash."
I reset my current epic to defaults, I disabled all my security settings and no luck. Any advise? Also I enjoy your browser. I owe you another donations soon.
I am on the East Coast USA.
