Repeated alert: "MAMP PRO.app" would like to access data from other apps

I recently migrated to a new Macbook Pro. Now every time I re-open Mamp I get the alert "MAMP PRO.app" would like to access data from other apps. Even if I choose to "Allow" it will pop up again if I close the app and open it. What is Mamp trying to access and why? Edit: I'm using the newest version of Mamp Pro 6.8
