also for Mac you may want to use this command in the terminal
xattr -cr "filepath"(or drag and drop app into terminal)
found the problem, also found a solution, when downloading something through safari, when that file is downloaded its auto extracted, which in some cases can corrupt the download, it then dumps the zip into the bin, what you need to do is delete that extracted file, and move the zip from the bin back into downloads and extract it manually, you'll see that when you extract it manually the icon should be a vial with some pink fluid, theirs nothing wrong with the game, its something about apple
