If you are familiar with the terminal window in mac you can use the following terminal directions:
Go to whatever folder that the later daters is in by typing cd <path to folder> Go into the app by following the path LaterDaters.App/Contents once in the Contents folder type: chmod +x MacO
And that will work, if you'd like a bit more clarity in directions, you can join our discord and we can chat you through it : https://discord.gg/fdHExNe
Thank you!
