You need to use QB Desktop 2024 Pro/Premier to convert data from QBO as the first step. Open the converted file on QB Desktop 2024 Pro/Premier and convert it again to QB Desktop 2024 Mac. If you converted it using QB Desktop 2024 Enterprise, you need to purchase a 3rd party service to downgrade your company file to QB Desktop 2024 Mac. You can contact Fiat Lux for assistance.
