Some of the apps on my MacBook Air (OS El Capitan) specifically my Grand Theft Auto are not opening because a prompt appears "Verifying (Name Of The App)". I've tried countless times to fix this but nothing has worked. Any suggestions on how might I fix this?

If you are sure that you downloaded the app installer from the official/verified source and that it has not been tempered with, you can skip the verification process altogether by removing the extended file attribute that causes FileVault to attempt to verify the application. Do this by executing the following command from terminal:
xattr -d com.apple.quarantine /Applications/app_name.appThe
app_name.appis the name of the application you are changing the extended attributes on. In this case,GTA5.app.The
xattrcommand allows you to view and change extended file attributes. The-dflag indicates you are deleting thecom.apple.quarantineattribute which is set on the application package. Any file with the extended attribute of com.apple.quarantine is verified by FileVault. This attribute is typically automatically set on downloaded files and files extracted from a tar or zip archive.
