The Mac will not run without the application Trigger. The reason for this is that the user must be able to accept or reject the operation of software as it is installed on the system. Trigger comes with a program called Mac Check. This can be used by the users in order to go back and review all the applications that have been downloaded on the computer.
With the latest version of the Trigger software, this feature has been upgraded to also include a check of the signature of each application that has been downloaded. Once the signature has been verified, the user is then given the option to accept or reject the installation of the application. If the signature is verified, it means that the software is original and is safe to be installed on the computer. However, if the signature is not verified, then it means that the signature is only the signature of the trial version.
Another function that can be checked using the Mac Check program is the decision on whether the software is compatible with the system. The compatibility of a program is checked by entering the name of the application in the box of the mouse. After which, the program name is compared against the list of compatible applications. If the application is not found in the list, then the user will be required to click on the X or close the application before clicking on the OK button.
