Which DAW is specifically designed to work only with Apple products?

Apple Logic Pro is the correct choice because it is a digital audio workstation (DAW) developed by Apple Inc. specifically for macOS and iOS platforms. This software is optimized for seamless integration with Apple hardware and software ecosystems, providing features tailored for music production, such as professional audio recording, MIDI sequencing, and a wide range of virtual instruments and effects.

In contrast, the other DAWs mentioned are not restricted to Apple products. For instance, Finale and Sibelius are widely used music notation software that operates on multiple platforms, including Windows. FL Studio is a versatile DAW that primarily runs on Windows, though there is a version available for macOS, making it less specific to Apple. Thus, Logic Pro stands out as the only DAW in the options that is exclusively designed for Apple products.
