The following are some known issues running the Project Paradise Demo version on Mac OS Big Sur (Version 11). If you're having a different problem with your demo copy on Big Sur, please post here.
ISSUE: When attempting to start progam, a system error is triggered: “You do not have permission to open the application”. This is a common issue with many programs attempting to run on Big Sur. You can read more on Apple's official support page here.
SOLUTION 1: First, confirm that permission settings for the game are correct. To do this, right click on the game program and select “Get Info”. At the bottom of this window, make sure that next to your user name you have the “Privilege” option set to “Read & Write”. Then, try right clicking the application and then selecting "Open".
SOLUTION 2: If that still doesn't work, open up Mac's Terminal program (Applications > Utilities > Terminal). Enter the following text exactly as you see it here:
sudo chmod -R 777
Once this text is entered exactly as above (with a single space at the end), drag and drop the Project Paradise Demo program from wherever you have it stored on your computer into the Terminal program. (This will add the file path of the game and manually give your computer the permission to open it)
Next, hit enter. You will be prompted for your user password. Once entered, this will give you permission to open the file.
SOLUTION 3: If you're still getting the permissions error, try updating your version of Big Sur. Do this by clicking the Apple icon at the top left of your screen, then clicking "About this Mac". In the box that appears, click on "Software Update..."
ISSUE: When trying to launch the game, an system error appears: "Project Paradise Demo" cannot be opened because the developer cannot be verified."
This is a common error when running any app downloaded from the internet (rather than downloading from the official App Store). You can find more information at Apple's support website here.
NOTE: Always be careful running software from unknown sources on your computer!
To allow your Mac to open the game, try this:
SOLUTION 1: Simply right click the program, then select "Open".
SOLUTION 2: Go to your Security & Privacy settings (click the Apple icon in the top left of your toolbar, then click "System Preferences", then "Security & Privacy")
Next, click on the “General” tab at the top of the Security & Privacy panel. At the bottom of the window, you will see the notification: “ “Project Paradise Demo” was blocked from use because it is not from an identified developer.” Click on “Open Anyway”.
ISSUE: When attempting to start the program, the error shows: ""Project Paradise Demo" would like to receive keystrokes from any application."
This is a known issue for Big Sur, and is a result of Apple wanting to discourage third-party software being installed on their computers. Further documentation can be found on the error on their official support page here.
To bypass this error, click on "Open System Preferences", then "Security & Privacy". Then, give Project Paradise access by clicking on the "Privacy" Tab, scrolling down to "Input Monitoring" in the left panel, and then adding "Project Paradise Demo" to the list of apps on the right.
