I have accidentally update a software that I use to access my patient charts. It will not allow me to open the app because my computer is not compatible with the new program. It is asking me to update my computer to 10.15 or newer. My MacBook is 10.13.6. How do I update my computer to the 10.15 software? I have gone to the app store and it says there are no new downloads or upgrades nor will it let me search for any. Please help
