The software installation package downloaded from the internet often prompts:
xxx is damaged and cannot be opened. You should move it to the Trash.
Now let's summarize the solutions.
In general, Method 1 and Method 2 can solve the problem. If neither of these two methods works, please try Method 3.
Method 1#
In System Preferences - Security & Privacy - General tab, select the option "Allow apps downloaded from: Anywhere".
Method 2#
If there is no "Anywhere" option, open Terminal and execute the following command:
sudo spctl --master-disable
Method 3#
If Method 1 and Method 2 do not work, execute the following command in Terminal:
sudo xattr -r -d com.apple.quarantine /path/to/app
where /path/to/app is the path where the app is located. For example, for XMind ZEN.app, it would be:
sudo xattr -r -d com.apple.quarantine /Applications/XMind\ ZEN.app
